1.1.1.24! root 1: 9F0629 Adapt autofire logic a little to work better with my new four-button ! 2: Competition Pro. ! 3: More small and relatively unimportant differences merged from WinUAE. ! 4: Delete more fast_copper pieces that escaped the previous purge. ! 5: 9F0317 Fix bsdsocket compilation problems. Include picasso96.h in ! 6: inputdevice.c. ! 7: 9F0211 Add NOINLINE macro. Turns out gcc-3.3.3 likes to inline large functions ! 8: but not small ones so we have to mess with noinline and always_inline ! 9: attributes. Fish. ! 10: 9E1113 Compile with gtk-2.0. ! 11: 9E1024 Remove fast copper code. ! 12: Created inputdevice.c; moved over some code from custom.c. ! 13: Merge further small pieces from WinUAE. 1.1.1.23 root 14: 9E1011 ALSA sound and SDL sound fix from Heikki Orsila. 15: 9E1010 Remove AHI code from audio.c; WinUAE didn't end up using it so there's 16: no point keeping it around. 17: Clear registers on reset; use calloc in mapped_malloc. 18: Work around REGPARAM problems with newer compilers. 19: Lose cpuopti, no point on current hardware and gcc breaks it too often. 20: Upgrade to newer version of autoconf (ugh). 21: Remove option stereo to sound_stereo to match WinUAE. 22: Make some variables static in cia.c. 23: Rename BPLPT[LH] to BPLxPT[LH], again to match WinUAE. 24: Import new identify.[ch] from WinUAE. 25: Move over exception and prefetch handling from WinUAE. Also remove last 26: traces of old (pre-Bernie) JIT compiler. 27: Import most of WinUAE's debugger. 28: 9C1003 gcc3 broke lots of optimizations. Fix the lossage by making 29: STATIC_INLINE contain the new always_inline attribute. 1.1.1.22 root 30: 9C0702 Correct an overflow problem in the CIA code. 31: 9C0407 Sprite code updates; correct CIA memory access handlers (Toni). 32: 9C0306 Make w/d representable for fsdb_win32. 33: Don't reorder children of directories; this causes duplicates in 34: exnext. 35: Reorder the code for the 9/10 vsynctime hack a bit. 36: Add code from Toni to remember the last value written to a custom 37: register and to return it when reading from a write-only reg - this 38: seems to match actual hardware behaviour. 39: Add some more blitter tweaks (Toni). 40: 9C0227 When waking up the copper from a blitter wait, recheck that vpos is 41: larger than vcmp - especially with masking going on, this may not be 42: the case. 43: X11: When changing picasso resolution, reinitialize everything - our 44: bitmap might be too small otherwise. 45: When configuring hardfiles, use specified blocksize, not 512 (Toni). 46: In SPRxCTL_1, don't examine vstart position before computing it (Toni). 47: 9C0225 Some cfgfile fixes, more blitter timing changes and one big sprite 48: statemachine update from Toni. 49: Some copper timing fixes. 50: Fix flag bit confusion in action_fh_from_lock (taken from earlier 51: WinUAE). 52: 9C0220 Blitter timing update from Toni. 53: Copper timing "theory" changed (me/Toni). 54: If we have a rdtsc insn, always synchronize with realtime in 55: vsync_handler. 56: Don't reset the lof bit when restoring state. 57: When restoring disk image names, put them in changed_prefs (Toni) 58: Return error in action_seek if trying to seek past end of file (Bernd 59: Roesch). 60: SDL fixes by Maik Qualmann. 61: Fix for gtk warnings when updating floppy LEDs (Maik Qualmann). 1.1.1.21 root 62: 9C0216 Fix the clockspeed detection - we were getting lots of alarm signals 63: even after it had finished. 64: Some tweaks for the GUI - and also fix the problem with waiting on the 65: GUI semaphore even if no GUI is present... 66: More accurate blitter timing (Toni). 67: Support for A1000 bootrom and CDTV/CD32 extended ROMs (Toni). 68: Fix filesystem lockup with "copy dh0: ram: all". 69: Fix for JIT and more than 2MB chipmem from Toni 70: Make fsdb_win32 accept more valid Windows filenames (Toni). 71: 9C0215 Fix filesystem reset code that used to access freed memory. 72: 9C0213 gtk UI fixes from Maik Qualmann. 73: 9C0113 Configury & bsd compilation fixes from Krister Walfridsson. 74: Match up lock/unlock calls in wgfx_do_flushline (found by Axel 75: Doerfler). 76: Fix potential crash taking strlen of NULL in filesys.c (Axel Doerfler). 77: Set diskdmaen to 0 in dsk_dmafinished (Toni). 1.1.1.20 root 78: 9B1230 lockscr/unlockscr fixes in drawing.c. 79: Add sdlgfx from Bernd [4] Lachner. 80: Filesystem asm code improvements from Toni (make it pic, call 81: setup_exter earlier in the boot sequence, etc.) 82: Also add Toni's patch to make rtarea position configurable (keep it 83: at 0xF00000 for now, though). 84: Avoid installing filesystem stuff if user didn't request to mount 85: directories. 86: BEAMCON0 is only available with ECS Agnus. 87: Revert some bogus parts of the write_log patch. 88: 9B1219 Add some missing clipping to the Picasso code. 89: Limit number of illegal-mem warnings. 90: 9B1217 Fix the GUI crash when changing floppies. 91: Changes to support programs that change between HAM/no HAM in the 92: middle of a line. 93: Some bug fixes, and a big fprintf->write_log patch from Alex Kazik. 1.1.1.19 root 94: 9B1125 Panning support for Picasso96 (in part from WinUAE). 95: More state save fixes from Toni, and a small disk.c update as well 96: which corrects track/gap lengths. 97: More evolution of the AHI code. 98: 9B1124 Merged a few more small pieces from WinUAE (larger pieces in case of 99: the Picasso code). 100: CLXCON2 was never called or statesaved. Fixed by Toni. 101: Sound sample frequency now always based on PAL timings. 102: 9B1123 Goodness! Massive memory corruption bug in picasso96.c - passing 103: last color changed to DX_SetPalette instead of count. 104: Fixes for the AHI code. 105: Changed prefetch emulation to be more similar to the one MAME uses. 106: Trace mode fixes (Bernd Roesch & myself). 107: 9B1122 Redo the ExNext code in the filesystem to make sure we always match 108: opendir with closedir and to fix some renaming problems. 109: Fix hd changing code in gtkui. 1.1.1.18 root 110: 9B1121 Mini-merge of noncontroversial WinUAE filesys.c code. 111: Add harddisk page to gtkui. Also change gui behaviour to wait for 112: the user to unpause before starting the emulator. 113: Add Toni's drive-led display. 114: Fixed a rather amazing source of crashes (we could fail to notice 115: the end of the frame in some cases). 116: Default to scanline mode. 117: Some tweaks to the SDL driver and the Win32 gui, mostly buffer-size 118: related. 119: Moved C source files back from tools directory (but still build them 120: there) to preserve my CVS history. 121: 9B1119 Move all the build tools (gencpu, cpuopti etc.) into their own 122: directory which is configured separately. This was necessary to 123: avoid picking up SDL CFLAGS (which can #define main to _SDL_main, and 124: that breaks if you don't link with SDL), and to make cross-compiling 125: at least a little more likely. 126: Remove sanity check for SDL header file - rely on sdl-config getting 127: things right (not that we have much choice). 128: Move thread support code past sound code in configure, and make sure 129: that SDL sound enables threads. 130: Move sername into options structure. 131: Check for existance of isinf/isnan before using them. 132: Rather large WinUAE merge - this tree compiles again under Windows. 133: Most of the additional features are missing though. 134: 9B1118 Restore code to mirror banks for 24 bit address space which got lost 135: when all the JIT memory changes were put in. 136: Speed up the CPU time calibration code. 137: Fix the broken file selector handling in the gtk ui. Add kickstart 138: selector. 139: Don't call XCloseDisplay, it apparently leads to crashes. 140: Try to solve the "missing write_log" problem in a sane way. 141: SDL joystick support. 142: When configure detects win32, use fsdb_win32 rather than fsdb_unix. 143: 9B1117 Proper masking for DDFSTOP; proper handling of AUDLEN == 0, changed 144: delayoffset code, gencpu BFINS fix, and lots of disk updates (all 145: Toni). 146: Some additional regs for move2c/movec2 (also by Toni IIRC) 147: 9B1115 COLOR_READ typo fix (Toni). 148: 9B1024 Filesystem reset leak fixes (Brian) 149: Allocate enough memory for custom state saving. 150: bploff renamed to bpl_off. 151: AGA copper cycle diagram (Toni) 152: Disable disk_data_used optimization. 153: 9B0926 Delayed palette setting for Picasso modes. Also fixed problem with 154: palette setting in CLUT emulation - we need to redraw the entire 155: screen if that happens. 156: 9B0921 Miscellaneous small bugfixes. Delete some obsolete code. 157: 9B0907 Beginnings of SDL support. Exterminated some penguins. 158: 9B0825 Some xwin.c fixes from Maik Qualmann. 1.1.1.17 root 159: 9B0730 Some sprite state machine tweaks. Fix sprite vs. DIW comparison. 160: HAM linebuffer was too small by half - oops. 161: Make absolutely, positively sure that when hsync_handler calls 162: sync_copper_with_cpu, we don't take any invalid shortcuts. 1.1.1.18 root 163: Memory management changes for JIT (Bernie [2], mostly). 1.1.1.17 root 164: 9B0729 Silly mistake - need to call flush_plane_data unless plfleft is 165: -1, even if no planes were enabled. 166: 9B0728 Small hack to reduce the time we lose with unnecessary 167: disk_doupdate_read calls. 168: Avoid calling flush_plane_data if we have no bitplanes enabled. 169: Tweak the SPCFLAG_INT handling to make "Delirium" demo work. 170: Limit rate of DDF warning messages. 171: Adjust display parameters so that things are shifted to the left 172: even more. 173: Fix (hopefully) CIA & blitter saving code. 174: 9B0727 Copper code reorganized; speedup code rewritten. Can now be 175: enabled with a GUI setting. 176: Fixed the delayoffset stuff. 177: 9B0725 AGA sprites, and some patches to sprite/playfield collision code, 178: mostly by Toni. 179: Fixed a small sprite restore problem; added missing code to map 180: fastmem banks when restoring them. 181: Some more state saving updates from Toni. 182: 9B0724 Fix a nasty bug in the copper SKIP instruction introduced by recent 183: changes. 184: Update the FAST_COPPER code. Not quite enabled yet. 185: More work on the memory configuration stuff. 186: Fix CPU type writeout in cfgfile.c (taken from WinUAE source). 187: Move the WOC demo BPLCON0 fix to compute_toscr_delay (Toni). 188: Added Toni's new disk patches, which include HD disk support by 189: Adil Temel. 190: Rewrote the memory and audio save/restore code. 191: Mask DDFSTOP with 0xFE, not 0xFC. 192: 9B0723 Yet another new and correct copper state machine (this time for sure) 193: Fix some AGA problems in DDF speedup code. 194: In gencpu.c, branch insns return a hardcoded cycle count; this had 195: not been updated for the CYCLE_UNIT stuff. Fixed. 196: xwin.c: If mouse is grabbed, we don't need mousehack. 197: Don't clear audio state if produce_sound == 0; this causes problems 198: if we want to turn the sound back on. 199: If an audio channel had a period of PERIOD_MAX, allow AUDxPER to 200: set its evtime back to a reasonable value. 201: Massive cleanup of memory initialization code; it will now use changed 202: prefs on reset. Added some memory options to gtkui.c. 203: Added Toni's state saving code, then added gtkui options and code to 204: initiate saving/restoring. 205: 9B0722 filesys.c: Fix writeout of hardfile params (Bernie [2]) 206: Add an A1000 Kickstart disk loader (Gerald Schnabel). Got rid of 207: the automount_uaedev code; we can detect the Kickstart version and 208: do the right thing. 209: Deleted a few unused variables (Toni) 210: Avoid aborting in decode_ham if Amiga code turns on the HAM bit but 211: has too few bitplanes (found by Toni). 212: Make the dummy mem bank return other values than 0; helps some 213: stupid memory detection code. 214: Implemented a little exec task lister for the debugger. 215: Added new debugger commands from Mark Cox. Improved his copper list 216: debugger by adding recorded timing information to it. 217: MOVE16 fixes from Gwenole Beauchesne. 218: xBCD fixes by Maik Qualmann, with some additional flag fixes by myself 219: (ABCD & SBCD behave exactly like on a 68000 now; dunno about NBCD). 220: 9B0520 AGA bscan2 fixes and disk.c kickstart speedup fixes from Toni. 221: Remove bogus changes I made to one of Toni's earlier disk.c updates. 222: Call RethinkICRA/B from INTREQ (suggested by Toni). 223: Properly save mixed_stereo setting. 224: NEGX uses X and Z (Bernd Roesch). 225: Danish keyboard support (Jesper Bojesen). 1.1.1.16 root 226: 9B0311 Repair "emulated but no output" sound setting. 227: 9B0310 Fix massive bug introduced in do_cycles_slow with the rescaling 228: changes. 229: CLXCON logic updated for AGA (Toni). Change meaning of collision_level 230: and add support for it in cfgfile.c. 231: 9B0309 Fix problem where a fsdb file could prevent deletion of otherwise 232: empty directory discovered by Torsten Enderling. 233: Rescale return values of CPU emulator functions. 234: 9B0225 Undo parts of the audio changes that made the "accurate" setting the 235: default. 236: 9B0221 Make fsdb_unix compile again. 237: 9B0219 Fix ddf for cases where start isn't aligned to fetchunit. 238: Fix some problems with the sound code going into infinite loops or 239: crashing. 240: Try to re-add Toni's ddf delay fixes properly. 241: Added a fix from Krister Walfridsson for X11 SHM code. 242: Rename OBJECT_NOT_FOUND to OBJECT_NOT_AROUND (not sure why, but the 243: win32 port does this; Fellow picked it up as well...) 244: Give in and allocate ainos with xcalloc. 245: Import fsdb_win32 code from Fellow. 246: Some tidyup and fixes in fsdb code. 247: Lose the lastdiv10 variable, and update CIA timers when reading them 248: (mostly by Bernie [2] Meyer) 249: Move reset_uaedevices and get_new_device to filesys.c. Add extra 250: parameter to get_new_device. 251: 9B0213 Fix mouse pointer jumping bug in X11 code (Ralf Hoffmann) 252: Scaled event handling by a factor of 512.

(Gee, games on the CPC and on 275: the Amiga actually have something in common - some of them crash when 276: the joystick is pushed in too many directions at the same time...) 1.1.1.15 root 277: 9A0825 Put in the new sprite code. This has existed for many months but 278: I've only now found the final bugs. 279: New version of Bernd Meyer's special_mem code.

Improve hardfile support in 718: tui.c. 719: 971031 Offer "-U" only ifdef PICASSO96. 720: Add support for mounting multiple hardfiles in any order. 721: Don't reset sprite state in init_hardware_frame. Instead, allow SPRxPT 722: functions to set the state to SPR_restart in the vertical blanking 723: area. 724: 971030 Fix 8MB Chip RAM. 725: filesys_dev_storeinfo: New function and calltrap. Use it to store 726: per-unit data (which now includes geometry information) in the 727: parampacket. Modify filesys.asm to use it instead of trying to find 728: the values by itself. 729: 971028 "AMIROMTYPE1" has 11 characters, not 0. 730: 971027 Implement encrypted ROM features. Comment out non-working InvertRect 731: optimization. 732: 971026 Fix some problems in PlanarToDirect and CopyColorIndexMappingA2U. 733: 971022 Remove fixed paths in genp2c.c (oops...) 734: Some more XF86VidMode hacks. 735: Include target.h in sysdeps.h. Define PICASSO96_SUPPORTED for X11, 736: SVGAlib and Win32. Don't compile in Picasso support if this macro isn't 737: defined. 738: 971021 xwin.c: Picasso code wants to use bit_unit, not bitdepth. Also correct 739: byteorder (it's B8G8R8A8 from the Amiga's point of view). 740: Fix Picasso InvertRect function. 741: Half-hearted attempt at 24 bit support in the X11 version, with some 742: awful code in custom.c. 743: Make the X11/VidMode version try to resize the screen for Picasso mode 744: switches. 745: 971020 Delete option -5, make -4 take an argument. Disable z3fastmem and 746: Picasso emulation when using a 24 bit address space. 747: 971019 record_color_change: No need to remember a color table if the current 748: line hasn't been decided yet. 749: Add XF86VidMode extension support. 750: Integrate Stefan's Zorro III support, add support for up to 64MB fast. 751: xwin.c: Refresh the whole Picasso screen if there are Expose events. 752: Fix module length calculation for *Tracker modules. 753: Use a 32 bit address space by default if CPU_LEVEL > 1. New option -5. 754: 971018 Apparently it's not possible to turn on bitplane DMA in the middle of 755: the line, so call post_decide_line only when the number of planes is 756: modified, not in DMACON. 757: genp2c.c: New file, generates planar to chunky conversion routines. 758: Remove those which are now generated from custom.c. 759: 971017 Make row_map an array, not a pointer to one. 760: Audio periods may not be 0, so initialize them to 65535 in customreset. 761: Implement "S" command in the debugger.

Move inhibit_frame stuff to xwin.h. 772: 971011 gencpu.c: Don't generate labels without following statement. Don't 773: directly generate assembly statements if X86_ASSEMBLY, instead generate 774: code that uses macros defined in machdep/m68k.h. 775: 971008 xwin.c, svga.c, custom.c, uaelib.c: Add picasso96 code. Add Picasso 776: selection to configure. 777: Move common variables (mouse stuff, gfxvidinfo, xcolors) from graphics 778: files to custom.c. 779: memory.c: custom chip area isn't supposed to be mapped at 0x200000. Use 780: dummy bank for now. 781: od-linux/joystick.c: Open different devices for different joysticks. 782: From Win32 sources: set vsyncmintime in m68k_go. 783: 971005 genblitter.c: blitzero is initialized to 1, not to 0, so we need to 784: clear, not set it. 785: 970928 Add another user interface for X11 using libgtk+. 786: 970925 audio.c: For stereo sound, double all lookup table values. 787: Added (preliminary) win32.c. 788: 970923 DISK_check_change: Should call gui_filename when ejecting. 789: 970922 Fix od-linux/joystick.c compilation problem with recent kernels. 790: Merge results of the UAE meeting: 791: New serial code (Stefan Reinauer) 792: Expansion "test card" support (Stefan Reinauer) 793: New GGI code (Christian Schmitt), also configure/Makefile changes 794: to make it compile. 795: Fix 68020/FPU code. 796: Call do_mousehack before every read of the mouse position to get more 797: accurate values. 798: Add sd-file directory; add support for it in configure. 799: Add stereo support in audio.c, od-linux/sound.[ch], and main.c. 800: Fix copper problem: call decide_line in calc_copcomp_true; and if the 801: copper wouldn't wait normally (position reached), but the hardware is 802: fetching data in Hires 4 plane mode, delay until ddf stop. 803: t-ascii.h: Asciiart target understands "-x" parameter. 804: 970823 gencpu.c [X86_ASSEMBLY]: Turn input constraints for scratch into output 805: constraints. 806: 970626 Fix 24 bit address space logic (Mathias Ortmann). 807: Raise exception 3 for Bcc.L insns if CPU_LEVEL < 1. Reported by Stefan 808: Ropke. 809: Remove USER_PROGRAMS_BEHAVE for normal emulator. Remove hacks to 810: generate expanded CPU functions for specific opcodes. Replace with code 811: that reads an instruction count file and sorts gencpu output by 812: frequency of the called opcodes. 813: 970625 Calltraps (at least those with call_m68k calls in them) were broken by 814: the CPU emulator changes. Now use Axxx opcodes as calltraps. 815: Include pOS port by Samuel Devulder. 816: 970624 Solaris sound patches by Manfred Thole. 817: gencpu.c: The generated code shouldn't just check for odd addresses, 818: it should also call Exception... 819: 970622 gencpu.c: don't emit return statements; make code jump to a function 820: end label instead. Make genamode() check for odd addresses, also reduce 821: code duplication. Interpret getv parameter so that data is fetched if 822: getv == 1, and the address is checked if getv != 0. Remove exception 3 823: checks from get_long() etc. Get rid of buserr. 824: cpuopti.c: Make a few more checks whether optimization is possible. Add 825: code to undo GCC's epilogue scheduling. 826: newcpu.c: Split all the specialflag handling into new function. 827: Implement -w option as in Win32 port. tui.c: add it to misc menu. 828: 907621 Fix yesterday's CPU emulator changes. Make cpuopti aware of functions 829: with two RET insns. Make sure that NO_EXCEPTION_3 and 830: NO_PREFETCH_BUFFER are on when emulating a 68020. 831: Add usage information for src/dst operands to table68k. 832: Implement CIA A OVL bit properly. 833: 970620 New NeXTwin.m from Ian. Fix a number of prefetch bugs in gencpu.c. 834: newcpu.h: m68k_incpc(), get_i{byte,word,long}: New function/macros. 835: Also add oldpc parameter to m68k_do_[bj]sr(). gencpu.c: use all this. 836: CPU functions now don't use nextiword; they keep the PC constant and 837: increment it with the right value at the end. 838: If chipmem_size > 2MB, disable fastmem. 839: In configure.in and od-linux/joystick.c, use ljoystick.h as name for 840: the replacement file for a broken <linux/joystick.h> 841: configure.in: Check for post-gcc-2.7.2 option "-mno-schedule-prologue" 842: and use it for compiling the optimized CPU files if it exists. 843: 970618 Rename hardfile.device to uaehf.device to avoid name clashes. Suggested 844: by George Nicolaidis. 845: Reimplement CPU prefetch by making gencpu aware of it so it generates 846: code that fetches data from the right places automatically. Also reduce 847: prefetch length to 4 bytes. 848: 970612 memory.h: Include osdep/memory.h. missing.c: implement xmalloc(). 849: Throughout: use xmalloc instead of malloc. 850: Apply changes by Sam Devulder. 851: 970608 Fix ncurses.c so that it links. Fix configure so that it can be enabled 852: Get rid of spixstate by implementing a new sprite drawing method. 853: 970607 do_copper_cheat(): New function, Implement inaccurate, line-based 854: copper as an option (-C). calc_copcomp_true(): Fix possible hr 4 plane 855: bug (split the wait into several pieces in this mode). 856: Allow 0 bytes for fast and bogomem (to override .uaerc) 857: 970606 Fix some bugs in transdisk, and make it compile with SAS C (Joanne Dow) 858: Stupid compilation fixes: Get rid of "==" in shell scripts, check that 859: B300 and friends are defined in serial.c before using them. 860: Implement blitter prefetch. Fix silly typo in main.c that prevented 861: immediate blits. 862: init_ham_decoding(): new function, handles case where the first few 863: pixels of a HAM display are outside the window. 864: 970605 disk.c: Get rid of need_read. Save cylinder/track number for the data 865: in the MFM buffer for each drive. Force rereads on disk insert and 866: write operations. In drive_fill_bigbuf(), do nothing if saved data 867: matches current. Fix disk change logic: give the program time to read 868: the change bit a couple of times before inserting a new disk. 869: custom.c: Fix really subtle bug: when deciding a line as border, 870: plfstrt/plflinelen were not set up properly, which could confuse 871: post_decide_line(), and eventually there would be lines decided as 872: playfield with plfstrt == 0, plflinelen == -32 ==> Bang. A related 873: bug was that setting DDFSTRT to 0 would result in both plfstrt and 874: plfstop having value 0. 875: gfxutil.c: Fix bug that could cause color values to go out of bounds. 876: xwin.c, svga.c: When dithering, color values were not doubled properly. 877: 970604 filesys.c: when deleting an a_ino, remove it from hash table (Mathias 878: Ortmann). In do_find(), if creating a file failed and we didn't have 879: an a_ino before, call delete_aino on the one we created. 880: More configure changes: Add $X_PRE_LIBS and $X_EXTRA_LIBS in some 881: places. See if MIT-SHM support for X will compile and link. Always 882: compile it in if it will. Turn DONT_WANT_SHM and LOW_BANDWIDTH into 883: run-time options (-T, -L). Use single line buffer when dithering and 884: in low-bandwidth mode (but in all cases there's a full buffer for the 885: X image). 886: memory.c: Don't map in custom regs at 0x200000 if chipmem_size > 2MB. 887: Split up init_sound(): new function setup_sound(). Make "-B" accept 888: minimum and maximum values as in Gustavo's latest patch. Add code to 889: tui.c to support changing buffer size, number of bits and frequency. 890: 970603 If using compiler, define NO_EXCEPTION_3 and NO_PREFETCH_BUFFER. 891: (bugreport by Raphael Poss). 892: GGI support from Christian Schmitt/Stefan Reinauer. More serial patches 893: from Stefan. 3 button joystick patch from Mathias. 894: Add linemem field to gfxvidinfo, for systems that don't want to keep 895: a buffer of the full screen. Adjust custom.c to use it instead of 896: bufmem if it's not NULL (mostly by Mathias). svga.c, xwin.c: Use single 897: line buffer in some cases. xwin.c: If USE_DGA_EXTENSION, undef 898: LOW_BANDWIDTH. Move test of DONT_WANT_SHM after inclusion of config.h 899: Make configure.in a bit more structured. 900: Move colormodes array to main.c. 901: 970602 gfxlib.c: Start implementing layers workalike. 902: md-i386-gcc/support.c: Don't mix sleep and alarm. (Petter Schau) 903: 970601 Remove may_run_compiled. Print error and abort if m68k_go is called 904: twice. 905: Fix yesterdays bugfix in svga.c. 906: Change FRAME_RATE_HACK so it tries to average the times a bit. 907: Re-implement a call_m68k function in autoconf.c. The new version 908: works by doing some heavy setjmp/longjmp magic and switching stacks. 909: With this, it's even possible to call things that Wait(), so use 910: the new functionality in gfxlib.c to call LockLayer() in WritePixel(). 911: 970531 Turn some inline functions in memory.h into macros. Get rid of 912: get_along and get_aword. Implement CIA A OVL bit. 913: main.c: Add missing close_sound() call. 914: Remove INTEL_FLAG_OPT, use X86_ASSEMBLY for everything. 915: tui.c/svgancui.c: Implement scrollable menus. Add code to select 916: video mode from a given list. Add "graphics_setup" call to graphics 917: specific files. Use it in svga.c to build a video mode menu. 918: Fix bug in svga.c that would crash non-linear modes. 919: disk.c needs to include gensound.h and sounddep/sound.h. 920: Fix bug in fuzzy_memset. In pfield_init_linetoscr, always adjust ddf 921: values if lores hack is being used. 922: 970530 Apply some patches by Samuel Devulder. 923: 970529 filesys.c: In "Houston, we have a problem" case, do not only delete 924: the oldest ExKey, but also use it instead of random memory for the 925: new one. Attempt to reduce the number of lost exkeys by allocating 926: them in action_examine_next instead of action_examine_object. 927: Initialize the "uniq" field of unit->rootnode. 928: Attempt to speed up sprite drawing loop. 929: Implement sprite<->sprite collisions. 930: Get rid of -Wtraditional. 931: 970524 New config option NO_PREFETCH_BUFFER. Emulate 16 byte prefetch if 932: unset. 933: For exception 3, the stack frame seems to be: 934: (saved SR).w, (faulting address).l, (faulting instruction).w, 0.w, 935: (pc at fault time).l. Make everything that could generate this fault 936: handle it properly. That got Cybernoid II working! 937: 970523 Makefile.in: Make sure $(DEBUGFLAGS) is used for CPU emulation files. 938: memory.c: Don't map chipmem at 0x200000, use custom chip bank for now. 939: 970507 configure.in: Mutate ac_cv_c_inline=no to ac_cv_c_inline= 940: Check for tcgetattr, <sys/termios.h>, cfmakeraw, <sys/ioctl.h> 941: Check for sem_init in -lposix4 (Marc Zimmermann) 942: serial.c, cia.c, cia.h, serial.c: changes (Stefan Reinauer) 943: Make disk gap 360 (Michael Krause) 944: 970404 In configure, check for features.h before including it in test program. 945: 970401 New option -4. Bugreport by Mirko Viviani. 946: 970324 Petter Schau says the exception frame for Bus Error and Address Error 947: is 14 bytes, not 6, on the 68000. Change Exception() accordingly. 948: It's *** OUCH *** day! Make hardfile beginio return the correct value. 949: Also load execbase before calling ReplyMsg(). 950: It's *** OUCH *** day again! The filesystem asm code was an odd number 951: of bytes, leaving the hardfile code unaligned. 952: 970318 custom.c: Rename spron to sprst, and use new variable spron to indicate 953: for which sprites the sprite pointer registers have been written. Don't 954: do sprite DMA if spron==0. (The problem was that some programs write 955: SPRxCTL and then SPRxPT, which used to set the sprite state to 956: SPR_restart, but it must be SPR_waiting_start.) 957: Turn a few m68k_reset()s into uae_reset()s. 958: New variable nr_joysticks. Delete joystickpresent. New arg "nr" for 959: getjoystate() and read_joystick(). 960: New extra keycode AK_RCTRL. Handle multiple joysticks & different key 961: replacements in keybuf.c/custom.c. Make tui.c handle all the settings. 962: 970310 od-linux/joystick.c now compiles again without the joystick header. 963: Fix some problems in configure; also check whether [n]curses.h defines 964: attr_t. Keep count of warnings and errors during configuration and 965: print a hopefully helpful message at the end. 966: disk.c sanitized by Mathias Ortmann. 967: Change the replacement getopt around a bit. 968: execlib.c, timerdev.c: Files removed. This will never be compatible 969: enough. Also remove related code (several SPCFLAGs, etc.) 970: Make main.c a bit nicer by introducing additional defines for the t-* 971: files. Also canonicalize the .uaerc file on all systems, eliminating 972: lines starting with '#' in the process. 973: Remove code in autoconf.c to set up 8MB chip; move it to filesys.asm. 974: Try doing the copper end-of-line hack in copper_memory_cycles(). 975: Disable the copper speedup hack. 976: 970309 Add a small, dumb hash table to struct _unit to speed up repeated 977: aino lookups. Delete aino in action_delete_object(). Move children in 978: action_rename_object(). In action_examine_next(), call new function 979: lookup_child_aino_for_exnext() which behaves more or less like 980: lookup_child_aino(), except it uses new function get_aname() to 981: translate filenames. 982: More portability fixes. New links set up in configure: sounddep, 983: target.h. All machine-dependent and joystick code removed 984: from os.c, renamed to audio.c. os.h renamed to audio.h, joystick stuff 985: moved to joystick.h. New directory targets/. 986: missing.c: New file. 987: 970308 Rewrite filesystem. Now it keeps one unique "a_inode" structure for 988: every object in the filesystem. This contains Amiga name, native 989: name, Amiga permissions, lock counts and several links for building 990: a tree structure. Keys are now made only for files which need a fd 991: and a file position. 992: Treat invalid locking modes als shared. 993: Comment out the code using readdir_r because that function appears 994: to be broken in glibc-2.0.1. 995: Clear RES2 in all packets before handling them. 996: Give mousehack the same task priority as the input.device. 997: Fix (?) some silly bugs in disk.c. 998: 970307 Include some Acorn port code from Peter Teichmann. 999: Yet Another Serial Diff from Stefan. 1000: 970306 filesys.c: Don't just crash if lookup_key() has no success. 1001: action_find_write() is supposed to create the file if it does not 1002: exist. 1003: 970305 More DOS patches. Make the Makefile parallel-make safe. 1004: svgancui.c: Do cyclic search if character is typed in file selector. 1005: my_alphasort(): New function (work around glibc bug) 1006: custom.c: Fix error in yesterdays change. 1007: filesys.h: New file. 1008: 970304 New serial patch from Stefan and Christian. 1009: Remove the assembler code to generate inputevents. Instead, add a new 1010: Amiga C program ("mousehack") which does the trick. New function 1011: mousehack_helper() in custom.c, activated by calltrap 0xF0FF70. 1012: Mouse default is now always normal_mouse, not follow_mouse. 1013: Do disk change checks only every 1/2 second. disk.c: Reverse 1014: nodskchange to dskchange, and make sure there has been a step with the 1015: drive empty before calling drive_insert() from DISK_check_change() (but 1016: this _still_ doesn't work. Arrrghh). 1017: 970303 filesys.c: Initialize _all_ of struct _unit in startup_handler(). 1018: Remove message_lock and friends and use new variables cmds_sent, 1019: cmds_acked and cmds_completed to determine when to send dummy messages. 1020: Changed examinekey handling so that "dir all" on a large tree doesn't 1021: crash anymore (it used to reuse the top-level exkeys which were still 1022: in use after a wraparound). Don't allocate examinekeys if we're 1023: examining files. 1024: Check for readdir_r in configure. Use a wrapper my_readdir() around 1025: either readdir or readdir_r. 1026: Call filesys_reset() also from filesys_diagentry(). 1027: Get rid of most of uaelib.c. Now there isn't a library, just a calltrap 1028: at 0xF0FF60. Changed uae_pragmas.h accordingly and recompiled uaectrl. 1029: Added a bunch of "volatile"s in various places in filesys.c and 1030: penguin.h. 1031: Make the filesystem reset-safe in the threaded case (paranoia changes). 1032: Check disk changes only every 1/10 second in vsync_handler(). 1033: Add assembler code to generate InputEvents once every vblank to 1034: filesys.asm. (Doesn't work yet.) 1035: 970302 filesys.c: Get rid of DosPacket type, pass pointers into Amiga memory 1036: instead. Use GET_PCK_* and PUT_PCK_* macros to access fields. 1037: Start making filesystem code thread safe & multithreaded. Move static 1038: variables from some functions into struct _unit, likewise the key 1039: and exkey variables. Add code to filesys.asm to queue commands which 1040: did not complete and to reply to them later. Do multithreading if 1041: compiled with SUPPORT_THREADS. See source for details. 1042: Change hardfile and uaelib code not to call 68k routines. Make emulator 1043: traps more efficient (no need to save regs, don't need SPCFLAG_EMULTRAP 1044: anymore). 1045: 970301 Fixed ncurses.c so it works with currprefs. 1046: filesys_reset(): New function, called from customreset(). 1047: Changed source layout. Break up machdep into machdep, osdep and 1048: threaddep. 1049: penguin.h: Now supports arbitrary types in pipes. 1050: Changed filesys.c so that no 68k code is called from native C code. 1051: filesys.asm, filesys.sh: New files. filesys.asm contains some 1052: startup code and the main loop for the filesystem. Several locks 1053: are allocated by the assembler code for use by the C code. 1054: DOS_AllocMem(), DOS_FreeMem(), make_dev(), build_parmpacket(), 1055: filesys_init(): Functions removed. 1056: 970228 ncurses.c: Fix problem in b/w modes. 1057: finish_drawing_frame(): Don't need to draw lines in multipenguin mode. 1058: Move all options into new struct uae_prefs. New variables currprefs, 1059: changed_prefs. 1060: svgancui.c, tui_filereq(): If user presses a key, start search at 1061: current position, not at the beginning. 1062: DISK_check_change(): new function, compares currprefs with 1063: changed_prefs and handles diskchanges if they differ. Called from 1064: vsync_handler(). 1065: DISK_validate_filename(): new function, checks whether a file exists. 1066: Modify svga.c and tui.c so that F11 now brings up a limited UI. 1067: 970227 Reimplement Mathias Ortmann's frame rate hack: New option HAVE_RDTSC 1068: in config.h. New typedef frame_time_t. New variables vsynctime and 1069: vsyncmintime. New function machdep_init() in md-*/support.c which 1070: sets up vsynctime in the md-i386-gcc and md-i386-linux cases. Use 1071: all of those in events.h, do_cycles() to determine whether to spend 1072: more time on the CPU emulation. 1073: Add missing "int i;" to xwin.c, init_colors(). 1074: Unroll some loops in sample_*handler(). 1075: Improve quitting/resetting behaviour: Move quit_program from GUI 1076: specific files to main.c. New functions uae_reset() and uae_quit(), 1077: quit_program is now handled in vsync_handler() and m68k_go(). 1078: New variable sample_evtime, used in customreset() and set up in 1079: init_sound(). 1080: 970226 Solaris sound update from Manfred Thole. 1081: keybuf.c: Decided that it doesn't need locking after all. 1082: Add a bunch of Gustavo's latest diffs. (I hate CR characters!) 1083: Move gfxvidinfo from all the target-specific files to custom.c 1084: More Win32 stuff: New function notice_new_xcolors(). 1085: 970225 configure.in: In shell string comparisons, always put spaces around = 1086: Add warning about standard SVGAlib being incompatible with 1087: LinuxThreads. 1088: os.c, SOLARIS_SOUND: Remove reference to obsolete variable smplcnt. 1089: Two new variables sound8_base and sound16_base. 1090: sysdeps.h: Split off some stuff into md-amiga/amiga-kludges.h. Also 1091: make the main types now uae_u32 and variants instead of ULONG, etc. 1092: Convert some files to use the new types. 1093: cia.c: use int/long instead of ULONG/UWORD/etc for most static vars. 1094: xdebug.c: Some cleanup. 1095: md-i386-linux/penguin.h: Fix bug. Add "chunks" parameter to 1096: init_comm_pipe. Use it to decide in write routine whether to signal 1097: the other thread if it's waiting. Add no_buffer parameter to 1098: write_comm_pipe_int. 1099: Start adding Mathias Ortmann's Win32 patches. 1100: md-i386-win32: New directory 1101: include/sysconfig.h.win32: New file 1102: custom.c: is_lastline: new variable, set in hsync_handler(). 1103: sysdeps.h: Make it possible for system specific code to say that 1104: POSIX/ANSI stdio/malloc functions aren't present and are defined 1105: by a system-specific file instead. In filesys.c, don't reference 1106: errno if DONT_HAVE_POSIX is defined. 1107: readcpu.h: Kludge around the fact that Messysoft C apparently doesn't 1108: handle enums properly. 1109: newcpu.c/sysdeps.h: Preprocessor magic for 64 bit constants to get 1110: around a problem with MS C. 1111: md-*/penguin.h: Add dummy definitions for semaphores. 1112: keybuf.c: Use semaphores to synchronize access. 1113: os.c, win32 sound stuff: add memcpy avoidance code. 1114: 970221 X86.S: Don't use .type ifdef USE_UNDERSCORE. 1115: Move thread support configuration to configure from config.h. Change 1116: pipe implementation to use POSIX semaphore functions. 1117: 970217 From Samuel Devulder: Fix off-by-one error in LINE_TO_SCR, EHB case. 1118: 970215 customreset(): Initialize current_colors.color_regs to invalid values 1119: [reported by Samuel Devulder]. config.h: Uncomment ECS_DENISE [reported 1120: by Mathias Ortmann]. Add ami-win.c and custom.c patch from Samuel 1121: Devulder. 1122: 970213 disk.c: Set FLOPPY_SPEED to 3 1123: custom.c: SPRxCTL_1(): if spron was SPR_restart set it to 1124: SPR_waiting_start. do_sprites(): don't do that. 1125: SPRxPT{H,L}: Call decide_line(). 1126: 970210 custom.c, X86.S: Do LORES_HACK for dual playfield screens. Plug memory 1127: leak in custom_reset(). Fix pfield_draw_line() not to do so many 1128: multiplications. Make line_changed a char array. In remember_ctable(), 1129: remember comparison results also if negative. 1130: In 8 and 16 bit graphics modes, use the high parts of the color values 1131: to duplicate the actual values. This saves a lot of code in the 1132: hdoubling routines. Add a special fill_line in the X86_ASSEMBLY case. 1133: Check for glibc-2 and libpthread in configure. 1134: options.h: In fuzzy_memset(), do rounding slightly more conservative. 1135: Add tons of new keycodes to svga.c 1136: In record_color_change(), also check if vertically outside DIW. 1137: New variable hdiwstate, to represent the horizontal DIW state machine 1138: (thanks Petter!) Handled in reset_decisions(), finish_decisions() and 1139: decide_diw(). 1140: 970209 Change ncurses.c not to do so many multiplications/divisions. Add bold 1141: character support. Add color support. Make configure recognize 1142: --without-svgalib and enable ncurses.c in that case. 1143: 970208 X86.S, custom.c: Do LORES_HACK for EHB screens also. 1144: New function write_log(); convert some fprintf(stderr, ...) calls. 1145: 970207 Argh, Linux/i386/ELF check in configure got broken by latest sh-utils. 1146: In disk.c, drive_reset(), clear nodskchange flag. 1147: 970206 Sprite fix from Mathias Ortmann: _really_ get rid of SPR_vtop, and 1148: replace all uses by SPR_stop. 1.1.1.2 root 1149: 970204 Disk change fix from Mathias Ortmann. 1150: 970203 New file ncurses.c, from Samuel Devulder. 1151: Disabled Exec stuff completely. Now it isn't even compiled in anymore. 1152: 970129 Changes from Samuel Devulder for Amiga and Christian Bauer for BeBox. 1153: 970122 Reorder the set_planes_unaligned functions so that better code is 1154: generated. Remove the or_planes_unaligned functions, add a parameter 1155: do_or to the set_planes functions and rely on the compiler to optimize 1156: the additional if away. 1157: post_decide_line() can now turn DMA off early. 1158: Make struct flag_struct 64 bits large for i386 systems, so we can use 1159: long move insns without clobbering the X flag. 1160: "make clean" should delete machdep/support.o. 1161: Maybe we do need SPR_vtop after all - undo 970120 change. Instead, 1162: comment out the code that clears the pos and ctl words at vsync time. 1163: In xwin.c, restrict window height to 300 or 600 depending on linedbl 1164: mode. 1165: 970121 Get rid of SPCFLAG_BLIT, call do_blitter() directly. 1166: In finish_decisions(), don't check for sprite draws in the border. 1167: Reimplement the SMART_UPDATE define so that the memcmpy() overhead can 1168: be avoided by not setting it (but this usually loses). 1169: Detect 7 lores planes in BPLCON0() and change to 6 to avoid memory 1170: clobbers. 1171: In pfield_draw_line(), do memcpy linedoubling after handling the line 1172: to be doubled, not when we see a LINE_AS_PREVIOUS. Get rid of prev_ypos 1173: parameter. 1174: Add special code for bpldelay1 == bpldelay2 to the UNALIGNED_PROFITABLE 1175: code. 1176: In pfield_init_linetoscr(), when delays 1 and 2 differ, clear the areas 1177: which are covered only by half of the planes at the start and end of 1178: the DDF area. 1179: Replace FASTER_CPU and LINUX_SOUND_SLOW_MACHINE with M68K_SPEED. 1180: Replace fast_unaligned_memset macros with fuzzy_memset; use this also 1181: in pfield_init_linetoscr(). 1182: Use real (PAL) vblank end in do_sprites(). 1183: 970120 Mask out high byte in DDF{STRT,STOP} 1184: Oops, forgot about long frames while calculating the bounds of all the 1185: maxvpos*2-sized arrays. Increment them all by two. 1186: Try to detect empty sprites before recording them for the drawing code, 1187: but be careful not to hurt attached sprites. 1188: From Paul Kienitz: hack for keyboard code in cia.c to work better with 1189: newer Kickstarts; small cleanup in cpuopti.c. 1190: Undo yesterday's change in copper_memory_cycles(), instead call 1191: decide_line() each iteration and test whether copper_cycle_time == -1 1192: to determine whether we're vertically in the DIW. 1193: calculate_copper_cycle_time() could get astronomical plane counts due 1194: to missing masking operation. 1195: No need to put the copper to sleep for one memory cycle after a WAIT, 1196: merge that with the two cycles for the next instruction. 1197: Get rid of SPR_vtop, no longer needed (it was unnatural anyway) 1198: 970119 Implemented alternate pfield_doline functions that access the apixels 1199: array at unaligned addresses; conditional on UNALIGNED_PROFITABLE. 1200: Move LORES_HACK from config.h to custom.c. 1201: Fix loop exit test for pfield_linetoscr_hdouble_asm8(). Clear the 1202: right parts of apixels in pfield_init_linetoscr() when LORES_HACK is 1203: enabled. 1204: Get rid of bordercol array: the decision-making code should handle 1205: lines in the border correctly by setting line_changed. 1206: Disable bitplane DMA if more than 4 hires bitplanes are set in BPLCON0. 1207: Fix some more copper timing inaccuracies: used to test 1208: thisline_decision.which without calling decide_line() before. 1209: 970118 Now remember BPLCON1 changes during data fetch. New functions 1210: decide_delay(), pfield_adjust_delay(); new fields in struct drawinfo 1211: and new variables next_delay_change, delay_changes. 1212: Forgot to set copstate to COP_morewait in one case in do_copper(). 1213: Add a kludge that checks for copper position 0xDC and changes it to 1214: 0xDE. 1215: Restore equality test for vertical sprite positions. Disable sprite 1216: DMA before the end of the vertical blank area. 1217: Mask not only the positions, but also comparison values in 1218: calc_copcomp_true(). 1219: 970117 Change custom_bput to put the byte value in each half of the word that 1220: is put. 1221: 970116 disk.c: Set the gap between sector 11 and 0 to 380 words. Andromeda's 1222: "Seven Seas" demo expects at least 320. Make the KILLEHB bit 1223: conditional on AGA_CHIPSET. Decide BPLCON1 (scrolling delays) in 1224: decide_diw(). Fix off-by-one errors in the very_broken_program case 1225: of decide_plane(). Fix aspect calculation when horizontal resolutions 1226: differ. Simplify copper horizontal comparison logic slightly. 1227: Fix divide by zero errors when reading from empty floppies. 1228: 970115 pfield_draw_line(): Check for frame_redraw_necessary also for border 1229: lines. New global variable pfield_last_drawn_line, used to implement 1230: clever Y centering. Make the KILLEHB test conditional on ECS_AGNUS. 1231: Move joystick and sound initialization before gui startup. Adapt tui.c 1232: so it understands the gfx_requested_* options. 1233: We can't always avoid clearing pixdata.apixels if DIW is larger than 1234: DDF. There may be sprites in the area outside DDF, but inside the DIW, 1235: so we can't just adjust linetoscr_diw_{start,end} blindly in 1236: pfield_init_linetoscr() [Sanity Arte demo]. 1237: 970114 Bebox diffs from Christian Bauer. 1238: Support for Symmetric Multi Penguins under Linux (start second thread 1239: with clone and use some pipes for communication - rather simpleminded 1240: for now). Rework do_flush_line() and do_flush_screen() so that X 1241: libraries are only called from the first thread. 1242: Eliminate valid field from struct decision (set which to -2 instead of 1243: valid = 0) 1244: Fix definition for gui_filename() in xdebug.c to use const char * for 1245: the second parameter. Remove CRs from disk.c (now how did they get in 1246: there??). Likewise for cpuopti.c. 1247: 970113 When post_decide_line() detects mid-line DDF change, must adjust 1248: bitplane pointers in decide_plane() also. Make plfstrt the earlier a 1249: position in this case, and adjust bitplane pointers/modulos 1250: accordingly. 1251: current_hpos() isn't what GCC calls a constant function. 1252: Replace line_drawinfo[current_change_set] with new variable 1253: curr_drawinfo throughout. Likewise for new variables prev_drawinfo, 1254: {curr,prev}_{color_{change,table}s,sprite_positions}; all initialized 1255: in init_drawing_frame (). Turn line_data into a 2dim. array, do some 1256: CSE/SR on line_data[lineno] in pfield_doline_{l,h}() and 1257: decide_plane(). Make some custom registers unsigned int instead of 1258: UWORD. 1259: calc_copcomp_true(): Masking with 0xF000 isn't likely to give 0xC0000. 1260: Comment out bplcon{3,4} from struct decision. 1261: 970112 filesys.c, action_set_protect(): if __unix is defined, check whether 1262: user wants to change directory protection, and if so, force rwx to be 1263: the new protection. 1264: Force sane window sizes in xwin.c, and set width/height from mode specs 1265: in svga.c. 1266: Implement LORES_HACK compile-time option. 1267: Whee, there _are_ broken programs that enable bitplane DMA in the 1268: middle of the data fetch area, draw half a picture on the first line 1269: and the full picture on all subsequent lines. New function 1270: post_decide_line(), called from BPLCON0() and DMACON() which tries to 1271: detect this case and turns the decision from border to playfield if 1272: necessary. 1273: New arrays, sprvstart and sprvstop, calculated in SPRxPOS and SPRxCTL, 1274: and used by do_sprites. Handle sprites with vstart == vstop correctly. 1275: Sprite vpos comparisons are now done with <= , not ==. 1276: _Now_ the X86-specific linetoscr routines do their masking correctly. 1277: configure: If we have GCC, #define GCCCONSTFUNC as __attribute__ 1278: ((const)) 1279: 970111 Eliminate can_draw from struct decision. 1280: Change vertical DIW code; use enum of two states (waiting for start and 1281: for stop) which is updated in decide_line(). Lines during the wait for 1282: stop phase are decided as border. No data is fetched outside the 1283: vertical DIW. 1284: Optimize copper memory cycle calculation a little: the new variable 1285: copper_cycle_time is set to a time >= 0 if this time is constant 1286: (i.e. 2). Calculated whenever DMA, BPLCON0, or DIW state changes. 1287: blitter.c, genblitter.c, custom.c: For BLTBDAT, follow the HRM which 1288: says that immediate data is shifted as soon as it is written. This 1289: seems to be wrong for the A channel, though. Also, don't change prevb 1290: during blitter loops if DMA B is off (Sanity Arte). Turn FAST_BLITTER 1291: stuff into run-time option "-n", and eliminate the ancient blitting 1292: code (former FAST_BLITTER == 0). 1293: Big OOPS: Copper move checked copcon, but there was no COPCON function 1294: so it was always zero -> copper-controlled blitter never worked. As a 1295: speed optimization, recognize 00010000 copper commands and put the 1296: copper to sleep until the blit is finished. 1297: Slow down the blitter in decide_line() if bitplane DMA steals blitter/ 1298: copper/CPU cycles (but this code is commented out for now). 1299: 970110 New function pfield_init_linetoscr(). Move calculation of diw_end and 1300: diw_start values there from x86-specific code. Also use DDF values to 1301: determine where data in pixdata.apixels is valid. The x86-specific 1302: linetoscr routines now only do the alignment masking (and they now do 1303: it correctly, too). 1304: Got rid of the display-related contents of struct draw_info, make 1305: static variables and them initialize from pfield_draw_line() only when 1306: necessary in function pfield_expand_dp_bplcon (). Get rid of the four 1307: saved_* arrays, remember line_drawinfo instead now that it's smaller. 1308: Color compare avoidance didn't work because color_src_match didn't get 1309: set when a compare was successful. Fixed. 1310: Reorder parts of the decision-making code so that less redundant checks 1311: are performed. 1312: Add clever x centering. Change "-O" option parameter format. 1313: In md-i386-linux/support.c, memcmpy(), do memcmp() first, then switch 1314: to a plain memcpy routine once we find the first difference. 1315: Patches from Stefan Reinauer/Christian Schmitt for 1316: xdebug.c/configure.in 1317: New uae-ui.tk from Volker Zota. 1318: Add --enable-profiling to configure.in. 1319: Check for period==0 in AUDxPER() was accidentally commented out - 1320: revert. 1321: 970109 Some tweaks in X86.S, plus a new option X86_PPRO_OPT to use movzbl 1322: instead of xorl/movb when possible. 1323: Fix maxline calculation in finish_drawing_frame(). 1324: Make next_lineno always a valid array index. Decrease minfirstline to 1325: 21 (NTSC vblank end). New option -O to specify display parameters, 1326: supersedes -d and -C which will be removed eventually. Differentiate 1327: between line doubling and aspect correction. Put aspect correction code 1328: in custom.c. 1329: Remove some more unused stuff from custom.c. 1330: Fix Makefile problems when cpuopti isn't used. 1331: 970108 use_lores isn't initialized before custom_init(), setup lores_frame and 1332: friends in customreset(). Optimize spixstate clearing. Optimize border 1333: drawing with copper color changes (use fill_line instead of linetoscr) 1334: Fix the sprite DMA logic, it now works with the Interference demo. 1335: Silly bug: Sprite 7 never got displayed (introduced sometime last week) 1336: Implement USER_PROGRAMS_BEHAVE for normal (non-compiler) CPU emulation. 1337: Add most of Gustavo's last patch (new dir md-i386-dos) 1338: 970107 Finish rewriting most of the drawing code in custom.c/X86.S. See 1339: README.PROGRAMMERS and source for details. Improvements include better 1340: copper precision, better interlace support, hopefully much less bugs 1341: and not too many new ones. 1342: Remove calc_adjustment() and gfxvidinfo.x_adjust; replace with code in 1343: custom.c that looks at gfxvidinfo.follow_diwstop (new field) 1344: Some operations (like EHB playfields) now have a higher penalty than 1345: before, the assumption being that these are rare and the normal case 1346: runs faster if it doesn't have to care too much about exceptions. 1347: Fix sign mismatch bug in BPL1MOD() and BPL2MOD(). 1348: 970104 Move x_ShowEA() from xdebug.c in newcpu.c, rename as ShowEA(). 1349: 970102 Add check for XK_W to decode_es() in xwin.c. 1350: New uae-ui.tk from Volker Zota. 1351: 961218 Add a patch by Bernie Solomon to overcome a problem with K&R compilers. 1352: Change X86.S in a way that may make it either faster or slower. 1353: Fix ADF_EXT1. 1354: 961217 #ifdef XK_dead_*, since Solaris doesn't have it. 1355: 961202 Fixed joystick.h problem in configure. X11/DGA support from Kai 1356: Kollmorgen. 1357: 961117 Some fixes in svgancui.c. 1358: 961112 Gustavo's latest patch, with GUS support for DOS by Michael Sontheimer. 1359: Add menu browsing to tui.c/svgancui.c 1360: 961107 Fix m68k_areg and m68k_dreg macros (put args in parentheses) 1361: Initialize gfxvidinfo.maxlinetoscr in xwin.c (found by Sam Devulder) 1362: 961104 svgancui.c tui_refresh() routine tweaked to work with the non-standard 1363: ncurses that came with my new SuSE-Linux CD. 1364: 961031 Added Christian Schmitt's xdebug.c (disabled for this release) 1365: 961024 Module search function from Michael Krause. 1366: 961019 Add Samuel Devulder's Amiga patches. 1367: 961018 Don't use -lm on NeXTStep. 1368: 961017 configure checks for -lforms. 1369: 961016 Ian Stephenson's new NeXTwin.m. Make CLXDAT return 0 (no collisions) 1370: transdisk and transrom patches from Rodney Hester. Don't warn about 1371: 256K Kickstarts. Check diskfile sizes and try to determine whether it's 1372: a normal or a HD diskfile. No HD drive identification yet (is it 1373: different?) 1374: 961013 Corrected lots of bugs in the return address stack. Fix some errors in 1375: the compiler memory management. Use the "locked" flag for hash entries 1376: differently, and don't enforce it on a cache flush. Compile JMP to a 1377: constant address. 1378: 961012 Remove regs from cache before sign extending them for ADDA, MOVEA and 1379: similar things. Compile NOPs to nothing. Implement variable shifts/ 1380: rotates. Most shifts clear the V flag: Handle this in the compiler by 1381: some extra magic sequences after shifts or in the CC_AFTER_RO case in 1382: flush_cc_cache(). 1383: Implement a stack containing return addresses and their hash entries, 1384: and compile JSR (to constant addresses)/BSR/RTS instructions inline. 1385: 961011 compiler.c: Several bugs introduced in the last two days fixed. 1386: New function compile_note_modify() which is used when an ea is 1387: modified. This replaces calls to storeea with eaino_s == eaino_d. 1388: Bah, the 386 doesn't set flags on a NOT. Use CC_TEST_REG again. 1389: Do flag life analysis until no more changes are found. 1390: Make sure all "data" parts of EAs are locked exclusively (esp. for 1391: LEA, PEA) 1392: 961010 compiler.c: Finish yesterdays changes. Get rid of reg/offset 1393: bookkeeping in m68k_compile_block(), keep the information in struct 1394: ea_info instead. Rewrite all instructions to use the new fetch and 1395: store routines. 1396: Don't force a byteorder conversion in sync_reg() if the reg doesn't need 1397: to be written back. Don't do a SAHF or equivalent in compile_condbranch 1398: if we are doing a BRA or BF. 1399: Don't use CC_TEST_REG for NEG and NOT (this was inefficient for NOT and 1400: wrong for NEG). 1401: 961009 compiler.c: Two types of locks for registers; shared and exclusive. 1402: Implement better EA fetching and storing routines. For pdi addressing 1403: modes, lock the necessary registers shared before calling prepareea. 1404: Unlock those registers again in generate_possible_exit(). 1405: 961008 MOVEM instructions in the compiler to an absolute address could have 1406: caused random memory corruption. 1407: 961007 Spanish keyboard support for X by Ruben Martinez. Some configure fixes 1408: (don't assume current dir is in path, don't assume ncurses.h exists if 1409: libncurses does). 1410: If we're calling 68k code from an emulator function, don't use compiled 1411: code. 1412: Add a compilation option USER_PROGRAMS_BEHAVE (for compiler). Make 1413: compiler hash table larger. 1414: 961004 Fix typo in configure.in. 1415: Modify the compiler so it doesn't ever throw away code, unless it's 1416: necessary for a cache flush. 1417: Didn't quite squash the compiler flag bug yesterday. Try again. 1418: In filesys.c, do_find(), add a parameter fallback that indicates that 1419: the open should be retried with O_RDONLY if it failed with O_RDWR. 1420: Use this in find_input(). This fixes problems with r/o files on r/w 1421: volumes. 1422: 961003 Play around with the x86 specific memory access functions. Problem: 1423: __attribute__((regparam)) isn't reliable, and it seems that that's a 1424: rather hard to fix bug in GCC. Add some alternatives to 1425: md-i386-linux/memory.h; these aren't used yet though. 1426: Huh, the compiler was completely wrong about the flag needs of 1427: conditional instructions. I wonder how it could work at all... 1428: Remove a and d arrays from struct regstruct; replace with array regs 1429: with 16 elements. This allows better code for get_disp_ea() 1430: 961002 BeBox diffs from Christian Bauer. Move all code from main() to new 1431: function real_main(). 1432: 961001 Use do_get_mem_*() functions for nextiword(), nextilong() and new 1433: function nextibyte(). 1434: 960930 genblitter optimizations: Don't generate expressions in genblitter, use 1435: a second program called gengenblitter to generate a table of 1436: expressions for genblitter to use. gengenblitter knows about a lot of 1437: rules to simplify expressions. Some other tweaks to make GCC output 1438: better assembly for blitfunc.c. 1439: 960927 Turn off LED() in xwin.c (may fix SunOS joystick emulation problems) 1440: Call XFlush() and XSync() when exiting. 1441: Add some DOS patches. 1442: Add hooks in filesys.c to support filesystem units in a GUI. Use them 1443: in tui.c. Bugfixes in svgancui.c. Change the way tui_refresh() works. 1444: New option "-A". 1445: 960925 For read-only filesystems (CD...), use O_RDONLY in action_find_input. 1446: 960923 Save options file even if rename fails. 1447: Mirror address space every 16MB like we used to (got turned off by 1448: accident). 1449: Move some checks out of options.h into configure. Set up md-* 1450: directories with machine-dependent stuff in them; configure creates 1451: a link called machdep to the appropriate one. 1452: 960918 Solaris sound update from Manfred Thole. 1453: 960917 Add a timer.device replacement (buggy). 1454: 960916 Tristan Cavelier's french keyboard patch. 1455: Apply ReadTheSpecsBeforeYouWrite(tm) technology to AddPort(). 1456: Implement RemPort(), GetCC(). 1457: 960915 Tighten up some of the return values in Exec. 1458: 960914 EXEC: Implement RemTask(), ObtainSemaphoreList() and 1459: ReleaseSemaphoreList(). Set up more fields of the ExecBase properly 1460: and Enqueue it in the library list. Make InitResident call AddLibrary 1461: when appropriate (otherwise, intuition is never put into the library 1462: list). Fix major braino in Obtain/ReleaseSemaphore() (tried to Enqueue 1463: tasks into two lists). Make OpenLibrary() honor the version parameter. 1464: 960913 EXEC: Idle task now runs in user mode (abuse 0xFF0D as second STOP 1465: instruction). Make EXEC_IntTrap perform the RTE before trying to 1466: schedule. 1467: 960912 Solaris sound didn't compile. So much for making blind changes without 1468: being able to test them. 1469: 960911 As soon as you compile it under Solaris, it bombs... Now check that the 1470: hardfile exists before determining the size in main.c. 1471: execlib fixes: Set master DMA enable bit at startup, fix interrupt 1472: code to survive an interrupt that occurs before the proper SetIntVector 1473: call. Implement RawDoFmt(), CloseDevice(), CloseLibrary(), 1474: FindResident(). 1.1 root 1475: 960905 Lower 8 bits of POTGOR should be 0. 1476: 960904 Implement MULU, MULS, ADDX and SUBX in compiler. 1477: 960903 ncurses interface works. DOS people: please use the new portable tui.c 1478: and turn dos-ui.c into a frontend for conio.h, similar to svgancui.c 1479: In xui.c, unlink the temporary files ASAP. 1480: Two new command-line options, "-o" and "-G". 1481: Get rid of sz_unknown. 1482: compiler.h, compiler.c: New files. 1483: filesys.c, action_read(): Added a hack to test whether the first four 1484: bytes read from a file a file contain 0x000003F3 (HUNK_HEADER), in 1485: which case there's probably a LoadSeg() call going on and we ought to 1486: flush the cache. Also, use the fact that memory is now linear. 1487: 960902 Struggle a bit with dos-ui.c, rename it to tui.c (text-based ui), add 1488: new file svgancui.c (ncurses ui) and try to make these two understand 1489: each other. 1490: 960829 New transdisk from Stefan Ropke (can write images) 1491: Apply Patrick Hanevolds BeBox patches. 1492: 96082x many changes to Exec. Still not booting (DMACON seems not to be set up 1493: properly, and sometimes Signal is called with task==0). 1494: 960821 Solaris sound from Manfred Thole. 1495: 960820 In filesys.c, get_fileinfo(), return volume name for top-level 1496: directory. 1497: 960819 Reimplement WritePixel(). Layer locking is still missing. 1498: 960818 Reverse meaning of -x flag for X11. More Exec code. 1499: Several changes to the main CPU loop and the way call traps work. 1500: 960817 Implement some simple Exec functions (Lists, AllocMem & friends) 1501: 960816 filesys.c fixes from David Varley. 1502: 960815 Implement graphics library region functions. 1503: 960814 Modify memory layout: All memory is linear now; get_real_address() 1504: returns a (UBYTE *). 1505: 960810 Add Gustavo's latest DOS code. 1506: In configure, include <sys/param.h> earlier for the sake of some *BSD. 1507: Add three options for sound code (bits, frequency, buffer size). 1508: Make -S option take a parameter; remove SPEED_UP_SIDMON_MODULES. 1509: New version of transrom (return 0, duh). 1510: 960805 Fixed the blitter line mode emulation (this time, really! I hope.) 1511: Thanks to Fabio Ciucci for a detailed description of the correct 1512: behaviour. 1513: 960730 Spent the last three days trying to make the filesystem emulation 1514: bootable by adding an expansion device for it. A fair bit of trial and 1515: error, but now it works! Even the hardfile now works with Kick 1.3, but 1516: you have to mount it manually after booting. 1517: hardfile.c, filesys.c, expansion.c and autoconf.c now are an 1518: entangled mess which badly needs to be cleaned up. 1519: We can now mount more than one filesystem even with Kick 1.3: we 1520: recognize them by param 2 of the startup packet, which has the same 1521: value as the dn_Startup field of the devicenode. 1522: Make Kickstart replacement work again (didn't like the CPU emulator 1523: changes) 1524: Include preliminary serial support from Stefan Reinauer. 1525: 960728 Fixed the scancodes for <> and #' keys in svga.c 1526: Apparently, CIA timer latches ought to be 0xFFFF after a reset 1527: (prevents Eagleplayer from crashing occasionally). #ifdeffed out a 1.1.1.2 root 1528: slightly weird call to INTREQ from RethinkICRB() 1.1 root 1529: 960727 Sound code rewritten again. Now uses events (five new ones). All 1530: modules seem to play correctly now. It's a bit slower, though. 1531: AF sound should work again, patches from Marcus Sundberg. 1532: 960723 ... and more CPU emulation bugs fixed by Herman. 1533: Added uae.library from Tauno Taipaleenmaki, plus support files in the 1534: "amiga" directory. 1535: Added some files for the XFree86/OS2 port from Krister Bergman. 1536: Reorganized all the directories. 1537: 960717 Add latest patch from Herman. 1538: More FAST_BLITTER options: 4 and 5. These finish the blit immediately. 1539: 960713 Call XAutoRepeatXXX() only if we know we want to change the state. 1540: 960709 Work around a few AIX bugs (ughhh... what a broken OS). New test for 1541: sys/select.h. 1542: In xui.c, don't try to communicate with a dead process. 1543: 960704 More bugfixes from Herman. 1544: Get rid of dummy_xlate(), use default_xlate() to abort with error. 1545: In svga.c, set correct_aspect to 0 if using lores. 1546: Change the Bcc exception 3 handling code a bit. 1547: Add new program "cpuopti" that takes gcc-generated assembly files and 1548: optimizes away unnecessary pushl/popl instructions on the x86. 1549: 960701 68020 exception handling & various bugfixes from Herman ten Brugge. 1550: In ersatz.c, use 0xFF0D instead of 0xF00D as trap opcode. 1551: Do MMU "emulation" (no-op MMU instructions, probably many cases decoded 1552: incorrectly). 1553: 960627 New file LIESMICH, with minimal German instructions. Somebody want to 1554: translate the docs to French, Spanish, Italian, all the Scandinavian 1555: languages, Hebrew, Polish, Dutch, Russian, Welsh, Gaelic and something 1556: [email protected] understands? (No offense meant - I'm sure there are 1557: brillant minds using AOL. There must be.) 1558: 960626 In zfile.c, make sure we delete the temporary file even if file 1559: decompression fails. 1560: Reimplemented sound support, this time following the HRM closely. Seems 1561: to work fine most of the time, but occasionally loses drum beats in 1562: TFMX modules. do_sound() is now unconditional, it calls 1563: flush_sound_buffer(), which is system-dependent. This breaks everything 1564: except Linux sound for now :( 1565: Add Herman ten Brugge's 68020/68881 emulation code. 1566: FreeBSD chokes if sys/mount.h is included without sys/types.h. Fix the 1567: configure script. 1568: 960622 More work on AGA code. 1569: Removed 2-bit display routines from custom.c. Ian: please use dithering 1570: code. 1571: Make slowmem and chipmem sizes run-time configurable. 1572: Mask out the high bits in BLT?PTH(). 1573: Add exception 3 checks to Bcc/BSR instructions. Seems to be not quite 1574: correct yet. 1575: Completely rewrote the disk emulation. We now create a big track buffer 1576: full of MFM data, used in a cyclic fashion by DSKBYTR() and friends. 1577: The current position in the buffer is determined by the cycle counter. 1578: DMA reads are now done in one piece. Two new event types: ev_diskblk 1579: and ev_diskindex. 1580: ARRGGHH! The RSI demo has _completely_ broken disk loading routines. 1581: They start disk DMA on a block while the blitter is still working on 1582: the same memory region. 1583: In zfile.c, unlink() the temporary file directly after opening it so 1584: it will be freed by the OS as soon as we close it (or crash... :) 1585: 960621 Merge pfield_sprite_h() and pfield_sprite_l() into one function. 1586: Split off new files blitter.c and blitter.h from custom.c. 1587: Fixed null-pointer dereference in zfile.c when filename has no 1588: extension. 1589: Add new field maxline to gfxvidinfo that prevents writing past the 1590: screen buffer if it has less lines than expected. 1591: Modify the 256 color allocation routine to set nb_cols to the same 1592: value first for r,g and b; allocate everything as usual and fill the 1593: lost colors afterwards with those that have the greatest difference. 1594: 960620 For some extremely weird reason, it is faster to simply call the 1595: assembly-optimized pfield_linetoscr_full routines _twice_ to double the 1596: line than calling the new (also assembly-optimized) 1597: pfield_linetoscr_full_double routines, at least when writing directly 1598: into the framebuffer. If someone has a good theory why, let me know 1599: about it. 1600: Drawing into memory is faster with the _double routines, but not 1601: noticeably (about 1%). 1602: Consequence: Removed the new pfield_linetoscr_full_double assembly 1603: routines again. 1604: Add a "--disable-gui" option to configure. 1605: Add Samuel Devulder's dithering code. Provide support for mono and 1606: 16 color X servers. 1607: Put an assembly version of DitherLine() in X86.S. 1608: New color mode (3) available, tells UAE to use 256 colors and dither 1609: the image. This is meant for people who have only a 256 color X server 1610: available, but it works with the SVGA version, too. It's much slower 1611: than normal 256 color mode, though. 1612: Use the color allocation algorithm from the dither code in 1613: alloc_colors256(), too. 1614: 960619 New files: zfile.c and zfile.h, from Samuel Devulder. These provide 1615: transparent decompression of various compressed file formats. Enabled 1616: by configure only for Unix systems. 1617: Eliminate dont_want_aspect. New option "-C", sets correct_aspect. Make 1618: video mode 3 640x480, video mode 4 800x600. Honor correct_aspect in 1619: 320x400, 640x480 and 800x600 mode with SVGAlib. 1620: Add fields maxlinetoscr and x_adjust to gfxvidinfo. 1621: Rename pfield_slow_linetoscr() to pfield_do_linetoscr(). Use new fields 1622: in gfxvidinfo to enable writing directly to the framebuffer in 1623: resolutions with <800 horizontal pixels. 1624: New function pfield_do_linetoscr_full(), called when sure that full 1625: line update is being done. 1626: Move some of the usage() information into some target_specific_usage() 1627: functions, defined in the various system-specific files. 1628: Support lower resolutions with LOW_BANDWIDTH, too. 1629: memcpy() within screen memory is dog slow. Prevent some common cases: 1630: 1. Use fill_line() to double a line in the border. 1631: 2. Add a parameter to pfield_do_linetoscr_full() to indicate whether 1632: the line has to be doubled. New functions 1633: pfield_linetoscr_*_double_slow() that simply do a memcpy(), plus 1634: optimized ones in X86.S that are much faster by avoiding the copy. 1635: Smart update code could get confused by lores modes when 1636: prev_max_diwstop changed from one frame to the next. New variable 1637: frame_redraw_necessary, which acts as a counter. It's initialized to 1638: 2 in interlace mode to handle that case properly, too. 1639: Move sprite priority checks into pfield_sprite_?(), move HAM 1640: calculations into new function decode_ham6() to simplify the various 1641: linetoscr functions. 1642: Fixed a bug that would cause sprites to get deformed in some cases 1643: when they overlapped (never seen it). 1644: 960618 New file: dos-snd.c, from Gustavo. 1645: 1646: 960617 Release 0.6.0 1647: 960617 Fix memory clobber in X86.S when diwfirstword==0. Eliminate double test 1648: for HAVE_SYS_MOUNT_H in sysdeps.h. 1649: 960616 Handle programs that don't wait for the blitter by finishing a pending 1650: blit as soon as a blitter register is written to (regardless of DMACON, 1651: to be safe). 1652: Call gui_led only if the LED changed. 1653: 960615 Fixed dual playfield sprite priorities. Optimized dual playfield code 1654: in X86.S. More work on AGA code. Get joystick status only in 1655: vsync_handler to speed things up. 1656: Make blitter fill more intelligent with table lookups instead of loop. 1657: 960614 DOS update from Gustavo. Pass real bitplane pointer to 1658: bpl_data_differs(), don't calculate it again. 1659: 960610 Fixed silly INTEL_FLAG_OPT bug: The new __asm__ expressions use 1660: regflags, which is of course _regflags on a.out... 1661: More BeBox fixes from Christian. 1662: Make the CIA bank bigger (A0..BF) and relax the CIA A/B selection 1663: checks to make broken software (Kingsoft's Emerald Mine, reportedly) 1664: happy. 1665: Default framerate is now 1. 1666: 960603 New BeBox code from Christian. Fix test for ELF in configure.in. 1667: 960529 genblitter.c: generate blitfunc as a function taking ULONGs and 1668: returning an ULONG. This makes custom.o about 4500 bytes smaller on the 1669: x86 by removing worthless size prefixes, and should increase 1670: performance (better for the cache, and the P6 reportedly doesn't like 1671: 16 bit instructions anyway). 1672: memory.c: Load Kickstart in one block and swap bytes after that if 1673: necessary (eliminates the need for the special bebox load routine) 1674: custom.c: Some preliminary work for AGA support. 1675: 960528 Saw a real awful piece of code that detects the right mouse button by 1676: reading a value from POT0DAT, counting up to 25, reading from POT0DAT 1677: again, and deciding the button is pressed if the value changed. Urgl! 1678: Added POT0DAT() in custom.c ... 1679: Gustavo's latest patches. 1680: 960525 Do index pulse handling in CIA_hsync_handler(). Make sure bit 12 in 1681: INTREQ gets set on an index pulse. Don't call DISK_Index() for now, 1682: since this breaks the Workbench. 1683: The CIA code should _probably_ not be resetting the bits in INTREQ. 1684: Disable this as an experiment, let's see what breaks. 1685: 960524 Z flag handling for ABCD/SBCD/ADDX/SUBX was wrong (must be clear if not 1686: zero, was set if zero). Some other flag bugs in these functions fixed. 1687: 960523 gfxlib.c update from Christian Schmitt. Some new Mac code from Ernesto, 1688: still not all of it, though. Italian keyboard from Alessandro Bissacco. 1689: 960522 Fix the CHK instruction. Implement middle mouse button. 1690: 960515 Fix some Nextstep problems in configure.in. 1691: 960513 New Makefile target "streifenfrei" to remove all output from configure. 1692: Use autoconf 2.7; 2.9 is buggy. 1693: 960512 Remove BIG_ALIGNMENT hack. Remove superfluous pfield_fetchdata() call 1694: in pfield_doline_slow_l() that resulted in garbage on the screen. 1695: Move blttbl array from custom.h to genblitter.c 1696: Use new lookup tables imm8_table and areg_byteinc in CPU emulation 1697: instead of ?: expressions. 1698: GCC appears to generate better code if the opcode is passed as ULONG to 1699: the CPU emulation functions instead of as UWORD. 1700: Modify some of the flag emulation __asm__ statements so that GCC uses 1701: less registers for them. 1702: 960510 Cast malloc() results to char *, for C++ compilers. 1703: 960509 Use test for GCC and __i386__ in options.h to decide whether to use 1704: intel flag optimization. 1705: Use test for wish4.0 to decide whether to use the GUI. 1706: 960507 New bebox.cpp from Christian. AF sound patches from Marcus Sundberg. 1707: 960505 Fix the configuration stuff so it works. Fix some bugs in gfxlib.c 1708: 960504 Use GNU autoconf scripts to generate Makefile and sysconfig.h. Add new 1709: files sysdeps.h that includes the right system header files. Remove 1710: amiga.h and Makefile. 1711: 960502 More Next code from Ian (new Uae.app directory, 2 bit drawing for 1712: custom.c). 1713: 960501 Allow the sound driver to set the frequency to a value that is slightly 1714: different from the requested one. 1715: 960430 Added AmigaOS port from Olaf Barthel. 1716: 960427 Fixed single playfield sprite priorities in X86.S. 1717: 960426 Added new NeXTwin.m from Ian. 1718: Turn off the blitter delay in line mode. 1719: Added a CPU optimization from Olivier Raoul: gencpu now reads a file 1720: "insncount" that can be generated by UAE during execution and generates 1721: specific functions for the most common opcodes. Not documented yet. 1722: 960414 Reimplemented the fast disk emulation in a more sane way. Also it's 1723: only done for reads now. (Plus, it no longer works :-/ Need to work 1724: some more on this). 1725: In blitter emulation, defer not only the setting of the bltfinish bit, 1726: but actually defer the whole blit for the number of cycles it will 1727: take. This makes programs the clear the screen while it is still being 1728: displayed look much better. 1729: Changed supervisor mode handling around a bit (was messy). 1730: New DOS code from Gustavo. 1731: 960412 Removed smart update method 2. Added Alessandro Bissacco's blitter 1732: optimization patch. 1733: Fixed some sprite problems: during hysnc, clear sprpos and sprctl, and 1734: don't do_sprites() in line 0. 1735: 960409 Be a little more intelligent about when to call pfield_linetoscr() from 1736: pfield_doline_slow(). It's only necessary if a color register changed. 1737: If it can be deferred to the end of the line, use the the _full 1738: variants. 1739: Some CIA TOD fixes. 1740: Better transdisk, accepts first/last track parameters. 1741: 960405 New function memcmpy(), inline assembler for the i386. Compares two 1742: memory blocks and copies them at the same time. Used in 1743: bpl_data_differs. 1744: 960404 French keyboard from Tristan Cavelier. Parallel port emulation from 1745: Stefan Reinauer. 1746: Turn bpl?pt and r_bpl?pt into arrays, simplify some code using them. 1747: 960401 Some parts of Ernesto's new Mac sources. 1748: 960331 filesys.c: Close filedescriptors in free_key(). get_path() sometimes 1749: read uninitialized bytes. 1750: Minor cleanups all over the place. 1751: unchain_mnn() leaves sibling intact, but clobbers next. customreset() 1752: didn't care about that and crashed. 1753: Use the __asm__("intel_flag_lookup") magic not only for DOS. 1754: Support 320x300 for X (without LOW_BANDWIDTH). 1755: Add new function fast_memcmp(), defined as memcmp if __i386__ is 1756: undefined, otherwise a slightly optimized inline assembly function. 1757: 960329 Some bug fixes in gencpu.c 1758: 960328 Stupid programs write odd playfield modulos into the hw registers... 1759: Eek! Sometimes, linedescr[] was indexed with a negative value... Add a 1760: vpos >= minfirstline check to pfield_may_need_update(). I really need 1761: to rewrite this in Oberon... 1762: Don't turn off SHM when LOW_BANDWIDTH is selected. 1763: Keep the nextpos and linepos variables from pfield_doline_slow_?() as 1764: globals and initialize them in pfield_may_need_udpate(). 1765: Modified alloc_colors256() some more. 1766: Try to make sprite DMA follow the Amiga DMA slots more closely by 1767: adding a currhp parameter to do_sprites() and calling it at the end 1768: of a scanline or in pfield_may_need_update(). 1769: 960327 Added Gustavo's latest DOS code, as far as possible. Modified X86.S to 1770: use a macro SYM() to create symbol names either with underscore or 1771: without. 1772: Fixed some very silly SVGAlib lores bugs. Move screen 8 pixels up in 1773: low resolution. 1774: Use diwstop instead of diwstart to caclulate the DIW for 320x200 modes. 1775: Reset it not only in calcdiw(), but also in init_frame(). 1776: Speed up 256 color allocation a little bit. 1777: 960326 New function flush_block() in xwin.c and svga.c. Called from 1778: do_flush_line() and (new function) do_flush_screen(). Modify struct 1779: vidbuf_description, new member maxblocklines that records the maximum 1780: number of scanlines that do_flush_line() should collect before calling 1781: flush_block(). If it is zero, then flush_line() is used as before. 1782: This makes the special case stuff for SHM unnecessary, so it's removed. 1783: Fixed a stupid bug in events code: Put ev_hsync in front of ev_copper, 1784: so that do_copper gets called with hpos == 0 instead of hpos == 227 at 1785: the beginning of the line. 1786: New function init_frame() that sets up some variables, called from 1787: customreset() and vsync_handler(). 1788: Move smart update code to pfield_doline() from pfield_doline_h() and 1789: ..._l(). Clean up these two with a macro DO_ONE_PLANE, removing 1790: duplicate code. 1791: Implement big blits and ECS chip ids. New configuration options 1792: ECS_AGNUS and ECS_DENISE. 1793: Implement MOVEP. 1794: 960325 Before calling pfield_may_need_update(), make sure the value that was 1795: written to a register actually differs from the previous one. 1796: New expansion code from Stefan Reinauer. 1797: Modify struct mem_notify_node to contain a pointer to a valid bit 1798: instead of the valid bit itself, so that the playfield code has to 1799: check only one flag to decide whether to draw the line (SU method 2) 1800: 960324 The chip_flags approach has several problems. A flag may cover an area 1801: in memory that spans two scanlines, or several scanlines may use the 1802: same area in memory. 1803: Provide two other, different methods for the smart update: 1804: 1. Save all the bitplane data for each line and compare the chipmem 1805: with the saved data to decide whether an update is necessary. 1806: 2. Use a chain of memory_notify_node structs instead of a single bit 1807: for flags. Each scanline owns a set of these structs and chains them 1808: into the right place, and the chipmem_?put routines walk the chains 1809: and set the modified bit for each element. 1810: Unfortunately, both methods are slower than the old one. Especially the 1811: first one has some advantages though: it speeds up programs that clear 1812: the screen each update and write the same contents back, and it 1813: can speed up double-buffering programs at full framerate, since it does 1814: not have to check whether the bitplane pointers have changed. 1815: Remember the first and last drawn line for each frame, and pass them to 1816: flush_screen. Use this in xwin.c for SHM. Modify SHM logic: if smart 1817: update is selected, call XShmPutImage() from flush_line() instead of 1818: from flush_screen(). But gather blocks of consecutive lines to avoid 1819: calling XShmPutImage() too often. 1820: 960323 "Smart update" method, based very loosely on Alessandro Bissacco's 1821: work, implemented: 1822: Add an array chip_flags that records any change made to specific words 1823: in chip memory. 1824: Move all the hardware registers relevant to playfield display into a 1825: new structure bplinfo. Remember the contents of this structure in 1826: struct line_description for every line on the screen. Avoid redrawing 1827: in pfield_doline if the screen memory has not been modified for the 1828: line to be drawn and if the information from the last frame matches 1829: that in the current frame. 1830: 960322 Duplicate all functions responsible for drawing (pfield_doline, 1831: pfield_doline_slow, pfield_sprite, pfield_*word_*res) and append _h 1832: or _l (ah, the golden C++ days, when we had templates... which never 1833: worked). Modify the *_l functions to support drawing in low resolution 1834: (i.e. 320x200). Change the options -d and -H to support selecting color 1835: mode and resolution, thereby getting rid of some SVGALIB_* options. 1836: Get rid of the old pfield_*word_*res functions. 1837: Collect information about the minimum diwstart value during the 1838: previous frame and use that in case 320x200 was selected to fit the 1839: image on the screen. 1840: Get rid of HAVE_JOYSTICK (breaks the "-J" option) 1841: 960321 Give up in op_illg() if opcode is 0x4e7b and the exception handler for 1842: it is NULL. In that case, it's a 68020 Kickstart. 1843: 960319 New Next code from Ian. SunOS target was still screwed (two CFLAGS). 1844: Turn -x option into a "hair cursor" option. Support multiple mounts, 1845: but warn if more than one is seen (still does not work with Kick 1.3). 1846: Integrated Samuel Devulder's new LOW_BANDWIDTH patch. 1847: 960318 Integrated the start of Markus Gietzen's gfx library replacement. 1848: Changed the interface between custom.c and the graphics code. There has 1849: to be a buffer holding the data of all the lines on the screen. For 1850: linear SVGAlib modes, this is the video memory. Eliminated -x option, 1851: prepare_line(), DrawPixel() and the X_?BIT_SCREEN options, replace with 1852: 3 versions of pfield_linetoscr for different datatypes. Implement 1853: proper handling of the borders above and below the DIW in custom.c 1854: instead of in flush_screen(). 1855: Move common code (color allocation) from all the graphics files to new 1856: file gfxutil.c. 1857: Swedish keyboard from Per Olofsson. 1858: 1859: 960315 Release 0.5.0 1860: 960315 Newest DOS port from Gustavo. New sgi-gcc target. 1861: 960314 Add -lXext to osf target. Use "rb" for fopen() in main.c 1862: 960310 Play a bit with the __asm__ constraints. Implement CHK. 1863: 960307 Fix some stupid Makefile errors. Call parse_cmdline() if no init file 1864: is found. 1865: First round of NextStep patches; new file NeXTwin.m 1866: Stupid bug in custom.c: The #define is called NO_FAST_DISK, not 1867: NO_FAST_FLOPPY. 1868: Fix one of the problems the Deform demo had with the blitter: The 1869: line texture wasn't rotated to the right position in blitter_init(). 1870: 960306 Use some black GCC __asm__ magic to calculate flags more quickly 1871: (config INTEL_FLAG_OPT) 1872: HAM was broken by pfield_linetoscr changes. Fixed. 1873: LOW_BANDWIDTH sometimes got confused when the display window changed. 1874: 960305 BCD instructions work well enough for Locomotive Basic on CPE. 1875: New function parse_cmdline_and_init_file() that reads ~/.uaerc or 1876: ./.uaerc and adds the options found in those files to those in argv[]. 1877: Patch from Denis Sablic to make disk image filenames runtime 1878: configurable. Extend it for the ROM filename. 1879: Remove some of the run-time configurable stuff from config.h. 1880: More X keysym fixes (I finally got a proper .Xmodmap ...) 1881: for SVGAlib: Delete key, and PgUp/PgDn as Amiga keys. 1882: The sound driver can now handle 22050 Hz and/or 8 bit samples. Both of 1883: these are the default with LINUX_SOUND_SLOW_MACHINE. 1884: Also use the SNDCTL_DSP_GETBLKSIZE ioctl and write the buffer when 1885: there is enough data. 1886: Abuse keybuf.c to provide a fake joystick emulation with the numeric 1887: pad (enable with -J) 1888: 960304 bebox.cpp from Christian. 1889: Rename pfield_linetoscr_full to pfield_linetoscr_full8. 1890: More x86 assembly: pfield_linetoscr_full16. 1891: 960303 SunOS target from Dirk Vangestel. Put some not-so-superfluous includes 1892: back in. Added the DOS specific patches to filesys.c. 1893: Started x86 assembly optimizations. New file X86.S, includes an 1894: optimized version of pfield_linetoscr (for 8 bit screens only). 1895: Don't use SA_RESTART if it isn't defined. 1896: prepare_line() wasn't called often enough (again...), leading to memory 1897: corruption and "hit the reset button" bugs when using SVGAlib. 1898: 960226 Get rid of bool, true and false in amiga.h and everywhere else. 1899: Copy yesterdays code to AF_SOUND code, too. 1900: Include first round of Christian Bauer's BeBox patches. Add AIX fix 1901: from Samuel Mackrill. 1902: Add #include <string.h> and #include <stdlib.h> in some more places. 1903: Modify gencpu.c and readcpu.c so that immediate types j and J (0..15 1904: and 1..8) can be merged. Replace HAVE_ONE_GIG... option with a new 1905: CPU_EMU_SIZE option that can be set to a value in the range 0..5, 1906: where 0 is minimum size and 5 is equivalent to HAVE_ONE_GIG... 1907: 960225 Remove multiplications in sound code, use a big lookup table. 1908: 960222 Go back to having only one memory bank table of type addrbank instead 1909: of several function pointer arrays. Eliminate the HAVE_BROKEN_SOFTWARE 1910: define by extending the memory bank table to 65536 entries. 1911: Remove remaining DUALCPU code. Allow BTST src,imm instructions in 1912: table68k. 1913: 960220 Back out filesys.c change from Stefan Reinauer: don't call V36 specific 1914: functions in expansion.library. 1915: Better fix for the filesys.c assign problems by Oliver Moehrke. 1916: Make new playfield code conditional on EXPERIMENTAL_SCREEN_UPDATE. 1917: Improve the 64bit variant of said code. Try to get alignment for 1918: apixels by putting it into a union with a long. 1919: Kill the child in gui_exit(). Make graphics_init() return a value and 1920: check it in main.c to see whether graphics were initialized. If not, 1921: call gui_exit() anyway. 1922: Use new 256 color allocation routine from svga.c in xwin.c, too. 1923: Make LOW_BANDWIDTH compile _and_ work (wow...). 1924: 960219 Fix bug in memory.c: When loading 256K Kickstart, copy 256K, not 128K. 1925: 960218 Finished the rest of the UI: reset, debug and quit buttons as well as 1926: drive LEDs. New target linux-gui; all others use dummy file nogui.c 1927: for now. 1928: 960217 The GUI now supports inserting and ejecting diskfiles and displays 1929: their names. Two pipes are used now, one for reading and one for 1930: writing. Properly wait for the process to start up. 1931: Use sigaction() instead of signal() in debug.c. 1932: More fixes for the new display routines: Need to do a final call to 1933: pfield_*word_*res with the data shifted right from the last fetched 1934: word. 1935: 960216 Copper & sprite bugfixes from Marco Nelissen. Better X keyboard support 1936: from Bruno Coste. 1937: Move my_strdup() from filesys.c to options.h 1938: New files xui.c, uae-ui (shell script) and uae-ui.tk (wish script). 1939: These create a GUI for the X version of the emulator. So far, the 1940: power LED works. 1941: 960215 Don't rely on SVGAlib headers defining any keycodes at all. 1942: Include Thorsten Frueauf's NetBSD patch. Apparently, the devname 1943: variable in hardfile.c caused a namespace collision, so rename it to 1944: uaedevname. Fastmem fixes, debugger help, and ConfigDev allocation in 1945: hardfile and filesys from Stefan Reinauer. 1946: xwin.c: Give the window a title. 1947: Half-implemented the DIVU.L, DIVS.L, MULU.L and MULS.L instructions. 1948: 960213 AF sound system support from Marcus Sundberg. Win95 keyboard support 1949: for SVGAlib from Thierry Lescot. Added most of Gustavo Goedert's MS-DOS 1950: port. 1951: When using the old pfield_*word_*res functions, the gen_pfield_tables() 1952: function was undefined. 1953: Hmmm, /dev/brain must have been unmounted when I wrote the new pfield_* 1954: functions. Now they make sure they access the apixels array only with 1955: addresses that are multiples of 16 bytes. 1956: 960212 Fix copy&paste bug in cia.c found by Marco Nelissen: Need to call 1957: RethinkICRB() instead of RethinkICRA() for CIA B timers. 1958: Added Stefan Reinauers autoconfig area/fastmem support. Added run-time 1959: options for use_slow_mem and use_fast_mem. 1960: Oops, the pfield_*word_*res() optimizations break completely on HPs and 1961: Sparcs. Now use this optimization only if we are using GCC 2.7. 1962: HPUX fixes in the Makefile. New target hpux-gcc. 1963: The code for clearing the areas above and below the DIW was trying to 1964: be a little too clever selecting the color. Just use the current 1965: background color. 1966: Added channel attachment to the sound code. Untested. 1967: 960211 Found some flag setting bugs in the rotate/shift instructions and in 1968: addx/subx (which I thought I had already fixed) by reimplementing 1969: DUALCPU mode to work with Ed's e68k. 1970: Argh! The copper is completely disabled during DDF in Hires 4 bitplane 1971: mode - so copper positions 0x30 and 0x34 are about 640 pixels apart. 1972: The Kickstart uses FF39FFFE to wait for the end of line 256 instead of 1973: FFDFFFFE as in all the other modes. This is implemented now, but 1974: probably not 100% correct. 1975: Added check whether SVGAlib doesn't support our mode. 1976: If using GCC >= 2.7, define __attribute__((aligned(16))) as 1977: BIG_ALIGNMENT in config.h. Use it for the apixels array to prevent 1978: potential problems on the Alpha. 1979: Tried to make the color selection routine produce better results in 256 1980: color mode. 1981: 960210 readdisk didn't work at all for large files - fixed. 1982: In pfield_doline(), clear the apixels array if playfield DMA is off. 1983: In SPRxCTL(), reset sprite mode when sprpos==sprctl==0 1984: Rewrite pfield_orword_hires() and friends to use lookup tables. No 1985: noticeable improvement on my machine, but might be different on other 1986: machines. Two versions of this code: one using 64bit longs on the Alpha. 1987: New targets linux-debug and linux-prof. 1988: Use 1MB slow mem. 1989: -funroll-loops is a little excessive. Remove it. 1990: Add support for linear addressing modes for SVGAlib version. Speedup 1991: is 20-30% on my old 486 VLB. Now, would someone please fix SVGAlib to 1992: support that for the S3-864 as well? 1993: Set SVGAlib keyboard mode to DONT_CATCH_CTRLC. 1994: Change custom.c, xwin.c and svga.c to keep track of the display window 1995: and background color and to clear the areas above and below the display 1996: window if necessary to remove garbage images from previous frames. 1997: Set the LOF bit in the Kickstart replacement init routine. Also 1998: initialize CIAs to Kick 1.3-like values. 1999: 960209 Some more -DHAVE_xxx_H options in the Makefile and filesys.c. DEC Alpha 2000: fixes for filesys.c from Ed and Marcus. HPUX fixes. 2001: New field in table68k for CPU type, parsed by readcpu and compared to 2002: CPU_LEVEL which is defined in config.h. New instructions MOVE2C, MOVEC2 2003: and CAS. Also a new field for priviledge level that is used by gencpu to 2004: generate tests for regs.s and Exception(8) calls if necessary. 2005: Move parsing of table68k into a new file build68k.c. Generate a file 2006: called cpudefs.c containing the information from table68k in 2007: machine-readable form. Change readcpu.c to use the array found in 2008: cpudefs.c. 2009: Don't generate the d8(An,Dn) addressing mode in-line. Generate a call to 2010: get_disp_ea(), which is an inline function in newcpu.h if UAE is 2011: configured for 68000 emulation; for 68020 emulation, it is defined in 2012: newcpu.c. 2013: Debugger could crash on illegals because there was no mnemonic defined 2014: in lookuptab[]. 2015: Return zero for SERDATR. 2016: 960207 It seems that the copper stops completely if an attempt to write to a 2017: specific register fails because of COPDANG. Apparently, the Kickstarts 2018: use this to stop the copper with a 0x00000000 longword. This leaves the 2019: question why they don't do 0xFFFFFFFE like everybody else. 2020: Enable 512K slow memory by default. 2021: Integrate Stefan Reinauers battclock patch that makes it work with 2022: newer Kickstarts. 2023: In cia.c, do the little index pulse hack even if dskdmaen==1, because 2024: DMA is only enabled when dskdmaen==2 (Helps the "Mad Decision" demo). 2025: Add solaris entry to Makefile (GCC, Openwin, -DHAVE_STATFS_H) 2026: Define HAVE_STRINGS_H for SGIs, change filesys.c accordingly. 2027: 960206 Build a smaller table instead of cputbl.c. Use readcpu and the smaller 2028: table to build the cpufunctbl array at run-time. 2029: Nuked the other half of the old CPU emulator. Reimplemented debugger to 2030: use the information generated by readcpu. 2031: Define HAVE_STATFS_H for SGIs in the Makefile, and use that as a test 2032: in filesys.c instead of #ifndef __linux. 2033: Hack filesys.c, get_path() to support the assign command. 2034: Add -fstrength-reduce and -funroll-loops in Makefile to make people 2035: nervous. 2036: Rewrite Sam Devulder's LOW_BANDWIDTH patch and add it to xwin.c. 2037: 960205 Forgot some PC-relative bit instructions in table68k. 2038: Nuked half of the old CPU emulator. 2039: Split gencpu.c into two parts, new one is called readcpu.c and just 2040: parses the table68k file. Link it to the main program. 2041: 2042: 960205 Release 0.4 2043: 960203 filesys.c, action_read(): Slightly more efficient code (translate Amiga 2044: address to real pointer). 2045: Moved some common code in the generate_* functions in gencpu.c to a 2046: separate function. 2047: 960202 Added an experimental fast disk option. Currently turned off by 2048: default (it's not such a big win). 2049: Attached sprite fixes (overlapping att. sprites looked bad, Katakis). 2050: Add sleep(1) before resetting the console to text mode when using 2051: SVGAlib: this might fix some screen corruption problems. 2052: Add sprite/playfield priority checking to the most important case 2053: (single playfield, no HAM). 2054: In filesys.c, do_find(): open() returns -1 on error, not zero. 2055: Return ERROR_OBJECT_WRONG_TYPE if do_find() is called for a directory 2056: (fixes Champions of Krynn harddisk installation). 2057: 960201 Don't abort if sound driver not present, just set produce_sound to 0. 2058: New files keybuf.c and keybuf.h to record keypresses in the right 2059: order and without losing any. In cia.c, force 15 scanlines between 2060: keypresses, just to be sure. 2061: unixfs.device _does_ work with Kick 1.3: just don't trust what Kick 1.3 2062: sends in the startup packet. For now, disable more than one mount per 2063: command line. 2064: Started integrating Ernesto's new Mac sources. 2065: Remove superfluous includes from some files. 2066: 960131 Added Ed's unixfs.device (great stuff). 2067: Adding ULONGs to pointers is a bad idea on the Alpha if the ULONG value 2068: really is signed. Add some casts to LONG in (pc_p + src) expressions 2069: in genpu.c. 2070: If DMACON is written and copper DMA is enabled, do a COPJMP1 at once. 2071: Helps the "Interference" demo. 2072: 960129 More SGI fixes from Ed. Bugfixes and transdisk improvements from Marcus 2073: Sundberg. 2074: Remove EXTRA_DEFINES from Makefile. Breaks some systems. 2075: Move common sprite code from pfield_doline() and pfield_doline_slow() 2076: to new function pfield_sprite(). The same sprite may appear more than 2077: once on the same line, so don't shift out the bits of sprdata[] and 2078: sprdatb[] while displaying it (Turrican I). 2079: In xwin.c and svga.c, barf if LINUX_SVGALIB doesn't match the file 2080: being compiled. 2081: Make all .o files depend on config.h in the Makefile. 2082: No need to exit if sound driver unavailable, but -S given. 2083: Small debugger fix: Missing space in output. 2084: Fix for the sprite logic: Specifically, use a state variable indicating 2085: whether the sprite has been restarted after a VSYNC. Fixes most 2086: Turrican problems. 2087: 960124 Added Denis Sablic's patch for sound run-time option. 2088: Added Ed Hanway's patch for better Makefile, X mouse cursor blanking 2089: and more SGI compilation fixes. 2090: 960123 Include options.h everywhere. 2091: Handle 8 bit GrayScale visuals like PseudoColor. 2092: Remove C++ leftovers from joystick code. 2093: 960122 When using the joystick driver, the button test must come after 2094: handle_events() in vsync_handler(). 2095: 960118 Removed all the remaining C++ comments. Changed all inline keywords to 2096: __inline__. Define __inline__ if not using gcc. 2097: Make proper prototypes for everything. Compile with maximum warnings + 2098: -ansi + -pedantic. 2099: Remove CIA_cycle(), obsolete. 2100: Reimplemented the STOP optimization in newcpu.c. Removed DualCPU 2101: support in CPU emulator. 2102: Real nasty bug in pfield_doline() fixed: sprxpos could be evaluated as 2103: negative, with not-so-amusing results. (Need to rewrite this in 2104: Oberon to get array bounds checking :-) 2105: 960117 Heroic effort: Rewrote the thing in C. This might help fix some 2106: problems with users being unable to compile it. 2107: Fixed a problem in hsync_handler(): Only call flush_line() for lines 2108: in the display window, i.e. when we did a prepare_line() before. 2109: Better code for relative branches: Don't use setpc(getpc()+x) calls, 2110: increment regs.pc_p instead. 2111: 960116 Reimplemented the function to load the Kickstart ROM. Use stdio instead 2112: of fstreams since this apparently does not work on the Mac. Detect 256K 2113: Kickstarts. Detect corrupt ROM images (calculate checksum). 2114: Added Ernesto Corvi's Mac port. Changed it around a bit, so it 2115: probably won't compile. 2116: 960115 Reinstate config.h options for X screen depth, so that DrawPixel() can 2117: be inlined in custom.cc for speed. xlinebuffer is now incremented in 2118: each call to DrawPixel() (for both X and SVGAlib) to get rid of some 2119: address calculations. 2120: 960114 Fixed X generic pixel drawing routine for SHM. 2121: Still trying to fix the harddisk emulation. 2122: uae.device no longer breaks the debugger (can step through uae.device 2123: functions now) 2124: Bugs affecting performance: SPCFLAG_STOP never got reset, and DSKLEN() 2125: would set SPCFLAG_DISK even if DMA was being turned off. 2126: Made slow memory a run-time option. 2127: Defer interrupts by one CPU instruction to give programs a chance to 2128: read INTREQR ("Seeing is Believing" and "Substance" demos) 2129: Added ScrollLock hack for X, too. 2130: 960113 SVGAlib version compiles again. Fixed SVGAlib mouse bug. 2131: Fixed SHM bug: Maximum scanline is 313, not 312. 2132: Sometimes, disk.cc missed a side change and would read the wrong data. 2133: Fixed. Apparently, this was the worst compatibility problem. 2134: Implemented trace mode. 2135: 960112 Changed layout of class amigamemory a little so that gcc can generate 2136: better addressing modes. 2137: Finally wrote functions in gencpu to generate MOVEMs. 2138: 960109 Integrated Ed Hanway's patches for better X support and run-time 2139: configuration of some options. 2140: Got rid of the direct VGA memory access. (Need to do this differently). 2141: Changed the method of drawing lines: custom.cc now tells the graphics 2142: code the line number and whether it needs to be doubleed before drawing 2143: it. 2144: Added Andre Beck's MIT-SHM patch. 2145: Remove warnings for newcpu.cc. 2146: 960108 Fixed exceptions in op_illg(): Need to decrement PC. 2147: 960107 Added an "uae.device" resident module at 0xF00000. This emulates a hard 2148: disk (fixed size 8MB for now). 2149: 960106 Moved some common code from pfield_doline() and pfield_doline_slow() to 2150: a separate function. This fixes a potential HAM bug (two static vars 2151: for the same value). 2152: Sound support for Linux. Works only with graphics off and the CPU 2153: slowed down. 2154: Better SVGAlib keyboard support. 2155: 960105 Added AvailMem(), AllocMem(), AllocAbs() and FreeMem() dummies. 2156: The Hardwired demo times the multiplication instructions and prints 2157: "This demo don't like Axel" if they are too fast. Apparently, Axel has 2158: a 68040. Added a WANT_SLOW_MULTIPLY option to config.h. 2159: Fixed the fast blitter emulation (seems to work now). 2160: 960104 Fixed all the ChangeLog entries from 95 that said 96 (oops??!) 2161: pfield_may_need_update() should check whether bitplane DMA is on. 2162: Added ersatz.cc and ersatz.h. The purpose of these files is to 2163: implement one or two Kickstart functions that are commonly called from 2164: bootblocks. This should help support some games and demos that only use 2165: the Kickstart as an initial track loader. So far, it's only good enough 2166: for one program. 2167: 951223 More intelligent event handling in the CPU emulator. Slightly faster. 2168: 951222 Optimize CPU emulation by inlining cctrue(). Also, the real PC no 2169: longer needs to be incremented each instruction. The real PC value 2170: now has to be fetched by m68k_getpc(). 2171: Added direct screen access for SVGAlib, but it didn't help much. I'll 2172: probably remove it again. 2173: The gencpu executable is 2M smaller if it allocates memory 2174: dynamically. 2175: 951216 custom_bput() enhanced a little. Now remembers the value that was 2176: written in the other half of the register. 2177: Apparently, the USEx bits of BLTCON0 are ignored in line draw mode. 2178: (Silents-Demo) 2179: 2180: 951212 Release 0.3 2181: 951212 Included Alessandro's battclock patch. 2182: Fixed mouse autocalibration for wrong-aspect screens. 2183: 951210 Joystick support for Linux. 2184: Better color matching for 256 color modes. 2185: Rewrote most of the memory management in plain C, mainly to avoid the 2186: various template bugs in some compilers, but also because gcc can't 2187: handle the regparm attribute for virtual functions yet. 2188: 951209 Added Alessandro's patches for automatic mouse calibration. 2189: Tried to optimize the blitter loop a bit. Doesn't work. 2190: 951205 Added Hannu's patches for diskfile write support. 2191: 951201 More portability fixes, especially for weird compilers that workstation 2192: vendors ship. 2193: 951125 More keys for X, some keyboard support for SVGAlib (slightly 2194: dangerous); beginnings of US keyboard support. 2195: 951124 256 color mode support for SVGAlib. FAST! 2196: 951123 Tiny tweak to central loops in playfield code results in much better 2197: assembly. Apparently, GCC does not feel too good about optimizing 2198: reference variables. 2199: 951113 Bug fix in the events code (nextevent must not be changed while events 2200: are being processed). 2201: 951112 The playfield can now be drawn with the right aspect (i.e., every line 2202: twice). Slower, but looks nicer and supports interlaced mode 2203: (flickerfree!). The first 29 lines (blanking interval) are omitted 2204: now to fit everything in 800x600. 2205: Oops, disk drive identification did not work. Fixed, all four drives 2206: appear now. 2207: Oops, CIA_reset() was there all the time but never got called. 2208: Optimized the planar->chunky conversion in pfield_doline() a little. 2209: This really is time critical. 2210: 951111 If colors change on a line, we might still be able to use the full 2211: line update, if the change occurred outside the DIW. Have to be a 2212: little careful, though. 2213: Playfield code now uses real pointers again, but makes sure it can 2214: read enough bytes to complete the current line without segfaulting. 2215: Oops, my "better estimate" (see below) was a mistake. Restored the 2216: original 4 hw cycles per instruction relation. This slows down the 2217: emulator while booting (more screen refreshs), but speeds up many 2218: demos that otherwise spend most of their time waiting for a specific 2219: raster position. 2220: Playfield modulos must be added immediately when DDF stops. (WOC demo) 2221: Portability fixes in disk.cc (null pointers). 2222: Implemented average frame rate calculation ('c' in the debugger). 2223: Debugger fixes. 2224: Sprite fixes (height was wrong, wrong priorities in fast update) 2225: Added an AutoConfig expansion RAM device. The OS seems to recognize 2226: it, but breaks sometime later (seems to be the same bug that kills 2227: the emulator when there's RAM at 0xC00000). 2228: SVGAlib now has mouse support, too. 2229: HAM mode implemented. 2230: 951110 Implemented fast complete line playfield update. Switches back if 2231: necessary. Fixed attached sprites bug. 2232: Copper wait no longer slows down the CPU emulation. (there were 2233: lots of new copper bugs because of this, but I hope I fixed all 2234: of them). 2235: Changed cia?t? from UWORD to ULONG, since there were overflows in 2236: the assertion (because of 65535+1 == 0). 2237: 951108 The DIVS remainder could have the wrong sign. 2238: New HAVE_BROKEN_SOFTWARE define in config.h that makes the emulator 2239: mask out the high byte of all addresses. 2240: Wrote genblitter.cc and replaced the awful code in blitter_blit() 2241: and blitter_line() with calls to the generated function. 2242: 951107 Implemented ?BCD. These don't really work yet. 2243: 2244: 951106 Release 0.2 2245: 951105 Fixed a bug in the new CIA timer code. 2246: Fixed flag settings for some cases of ADDX/SUBX 2247: 951104 Changed the main loop a bit - call all the *cycle() functions only if 2248: it is really necessary. I hope everything still works - at least it is 2249: twice as fast now :-D 2250: Improved mouse emulation - avoid overflows, permit "wraparound". 2251: Added debugger 'g' command. 2252: Removed some useless casts from the CPU emulator. 2253: Added a configuration option to prevent checks for odd addresses. Only 2254: very bad programs need this check. 2255: 951103 The sprite emulation sometimes did not work too well, especially with 2256: dual playfield mode. Hopefully fixed. 2257: 951102 The 10 cycle counter is more like a 5 cycle counter in this 2258: implementation. (Fine, that makes floppy loading even faster :-) 2259: Implemented mouse movement. Totally out of sync with the X pointer, 2260: but at least something. 2261: Found out about the XAutoRepeatOff() function. Real useful. 2262: DualCPU mode works again. 2263: Corrected flag settings for CMPA.W. 2264: Fixed DIV instructions: Don't change dest in case of overflow. 2265: 951031 The PC is now converted to a real pointer. This is safe (much safer 2266: than converting bitplane pointers, since the PC always has to be valid) 2267: and should speed things up a little. 2268: 951029 Some primitive event handling: 2 mouse buttons and 1 joystick button 2269: are emulated, as well as parts of the keyboard (only german mapping). 2270: Fixes: Delay values and sprite widths are always LoRes. Playfield 2 2271: uses colors 9..15. 2272: Implemented a frame rate configuration option that can speed up the 2273: emulation quite a bit. 2274: 951028 A-ha. The 68000 has one strange feature after all. MOVEM.W to Dn sign 2275: extends the value to a longword. 2276: Katakis expects that accessing odd addresses causes exception 3, so 2277: we have to emulate this. *Sigh* 2278: Do at least something with the index pulse bit. It's more or less a 2279: toggle now. 2280: Implemented sprites & dual playfields, both with small glitches. 2281: 951027 When LOF is set, the frame is one line longer. 2282: 951026 Implemented a preliminary diskfile type for special formats. Turrican 2283: boots up correctly (crashes if I want to play a game, though). 2284: Implemented EHB and added a few missing masking operations in the color 2285: handling. 2286: Fixed the absw addressing mode - need to sign extend here as well. 2287: 951025 Fixed another extremely stupid bug, this time in the playfield code. 2288: Each pixel was calculated four times... 2289: Increased the size of the apixels array - this was being overrun. 2290: 951024 Fixed an extremely stupid bug in flag settings for byte and word 2291: operations. 2292: The "sectors until gap" field must be in the range 1..11 instead of 2293: 0..10, or very bad things will happen if it is used to calculate a 2294: blit size. 2295: 951021 Don't use real pointers to fetch bitplane data - too many segfaults. 2296: Delay the copper after executing an instruction, or wait sequences like 2297: FFDF FFFE 0200 FFFE won't work. 2298: Some programs expect that the CPU is completely turned off if the 2299: blitter nasty bit is set. So be it. 2300: The RSI Megademo chokes when disk DMA fetches two syncs. Leave one out. 2301: The LOF bit wasn't set correctly. 2302: 951020 Blitter fixes: Load fill carry from FCI each line; keep the masked 2303: value of bltadat in bltolda 2304: Give the CPU twice as many "cycles" - this still is not even remotely 2305: correct, but a better estimate. 2306: 951017 Added SVGAlib support. Unfortunately, my graphics card isn't fully 2307: supported by the current SVGAlib version. 2308: 951015 More small optimizations to memory.h and custom.cc. 2309: Added code for 256 color screens. The type of screen has to be 2310: selected at compile time. 2311: 951014 Modified the memory management to be (hopefully) a little more 2312: efficient. 2313: Changed gencpu.cc to generate functions and a big function pointer 2314: array instead of the old case labels. The generated C++ files now 2315: compile a lot faster, and the code should be better as well. 2316: 951013 Implemented pseudo POTGOR to keep the RMB from being detected as 2317: pressed all the time. 2318: GenerateDecTab() generated TRAP incorrectly. 2319: Made some more instructions (MOVE.B A0,D0 etc) illegal in gencpu.cc. 2320: Fixed X colors. Fixed data fetching for HiRes screens. 2321: 951011 EXT.WL instructions set the flags. 2322: Implemented second CPU emulator, plus "DualCPU" option. The new CPU 2323: emulator is generated automatically from a file called table68k by 2324: a program called gencpu. 2325: 951002 Removed version information from the file headers. 2326: Removed some sillinesses in custom.cc. 2327: DSKLEN bug fixed (mask out 0xC000). 2328: Playfield code rewritten. Now supports horizontal scrolling. Implemented 2329: some primitive color support. 2330: 950927 Fixed predecrement/postincrement addressing with byte size for the 2331: stack pointer. 2332: 950926 Fixes to the disk code: Terminate disk DMA, flip disk side, read more 2333: than just two sectors during disk DMA, fix checksum calculation. 2334: Fixed copper comparison bugs. 2335: 2336: 950901 Release 0.1 2337: 950826 bugfix in GenerateDecTab(): LEA.W instructions were generated. 2338: 950312 New file disk.cc, for (guess what) disk support. Doesn't work yet. 2339: 950311 Multiplication instructions were generating 16 bit results. 2340: Sign extension was wrong in some places. 2341: Removed bugs in the blitter (one word width: ALWM & AFWM and line mode) 2342: The Kickstart logo looks perfect now. 2343: Playfield routine should check BPLCON0 instead of BLTCON0 2344: 950309 ASR D8,D0 is not a valid instruction. 2345: Bitplane pointers were not incremented. 2346: Copper comparison didn't work. COP2LC and bitplane pointers were written 2347: incorrectly. Fixed. 2348: Something that bears a striking resemblance to the familiar Kickstart 2349: logo now appears in my X window! 2350: 950306 ROR used to set the X flag. Bug fixes in GenerateDecTab. 2351: More bug fixes in several 68000 instructions. 2352: Improved blitter. ?????? KS1.3 doesn't seem to set BLTDMOD on a 2353: line draw. What is this?? 2354: Fixed stupid bugs in playfield code. 2355: 950305 fixed bugs in opcode generation and interrupt handling. Implemented 2356: STOP. Fixed flag settings: Result wasn't masked. Ooops!! 2357: ADDQ #imm,An doesn't set flags. 2358: One-shot timer mode didn't work. 2359: Implemented blitter, doesn't work. 2360: Some primitive and slow playfield support, only to make the things that 2361: hopefully will soon appear visible. 2362: 950304 CIA timers ought to work OK. Copper is emulated. 2363: Emulator loops infinitely when trying to initialize the console.device 2364: 950303 experiments with X, figured out how to open a window and draw pixels. 2365: No graphics emulation yet, though. 2366: 950301 Nearly all instructions work. 2367: Fixed supervisor mode stack. 2368: The memory manager now handles CIA chips. 2369: 950228 Bug fixes in 68000 code, exceptions and more instructions implemented 2370: Memory management extended to handle custom chips as well. 2371: Debugger improved. 2372: Kickstart passes memory & CPU type test, builds up some system 2373: structures. 2374: 950227 MC68000 & little debugger for tracing. It can execute the first couple 2375: of KS1.3 instructions, but doesn't get past the memory test. 2376: 950225 Work begun
