Fixed by Toni. 40: Sound sample frequency now always based on PAL timings. 41: 9B1123 Goodness! Massive memory corruption bug in picasso96.c - passing 42: last color changed to DX_SetPalette instead of count. 43: Fixes for the AHI code. 44: Changed prefetch emulation to be more similar to the one MAME uses. 45: Trace mode fixes (Bernd Roesch & myself). 46: 9B1122 Redo the ExNext code in the filesystem to make sure we always match 47: opendir with closedir and to fix some renaming problems. 48: Fix hd changing code in gtkui. 1.1.1.18 root 49: 9B1121 Mini-merge of noncontroversial WinUAE filesys.c code. 50: Add harddisk page to gtkui. Also change gui behaviour to wait for 51: the user to unpause before starting the emulator. 52: Add Toni's drive-led display. 53: Fixed a rather amazing source of crashes (we could fail to notice 54: the end of the frame in some cases). 55: Default to scanline mode. 56: Some tweaks to the SDL driver and the Win32 gui, mostly buffer-size 57: related. 58: Moved C source files back from tools directory (but still build them 59: there) to preserve my CVS history. 60: 9B1119 Move all the build tools (gencpu, cpuopti etc.) into their own 61: directory which is configured separately. This was necessary to 62: avoid picking up SDL CFLAGS (which can #define main to _SDL_main, and 63: that breaks if you don't link with SDL), and to make cross-compiling 64: at least a little more likely. 65: Remove sanity check for SDL header file - rely on sdl-config getting 66: things right (not that we have much choice). 67: Move thread support code past sound code in configure, and make sure 68: that SDL sound enables threads. 69: Move sername into options structure. 70: Check for existance of isinf/isnan before using them. 71: Rather large WinUAE merge - this tree compiles again under Windows. 72: Most of the additional features are missing though. 73: 9B1118 Restore code to mirror banks for 24 bit address space which got lost 74: when all the JIT memory changes were put in. 75: Speed up the CPU time calibration code. 76: Fix the broken file selector handling in the gtk ui. Add kickstart 77: selector. 78: Don't call XCloseDisplay, it apparently leads to crashes. 79: Try to solve the "missing write_log" problem in a sane way. 80: SDL joystick support. 81: When configure detects win32, use fsdb_win32 rather than fsdb_unix. 82: 9B1117 Proper masking for DDFSTOP; proper handling of AUDLEN == 0, changed 83: delayoffset code, gencpu BFINS fix, and lots of disk updates (all 84: Toni). 85: Some additional regs for move2c/movec2 (also by Toni IIRC) 86: 9B1115 COLOR_READ typo fix (Toni). 87: 9B1024 Filesystem reset leak fixes (Brian) 88: Allocate enough memory for custom state saving. 89: bploff renamed to bpl_off. 90: AGA copper cycle diagram (Toni) 91: Disable disk_data_used optimization. 92: 9B0926 Delayed palette setting for Picasso modes. Also fixed problem with 93: palette setting in CLUT emulation - we need to redraw the entire 94: screen if that happens. 95: 9B0921 Miscellaneous small bugfixes. Delete some obsolete code. 96: 9B0907 Beginnings of SDL support. Exterminated some penguins. 97: 9B0825 Some xwin.c fixes from Maik Qualmann. 1.1.1.17 root 98: 9B0730 Some sprite state machine tweaks.

Can now be 114: enabled with a GUI setting. 115: Fixed the delayoffset stuff. 116: 9B0725 AGA sprites, and some patches to sprite/playfield collision code, 117: mostly by Toni. 118: Fixed a small sprite restore problem; added missing code to map 119: fastmem banks when restoring them. 120: Some more state saving updates from Toni. 121: 9B0724 Fix a nasty bug in the copper SKIP instruction introduced by recent 122: changes. 123: Update the FAST_COPPER code. Not quite enabled yet. 124: More work on the memory configuration stuff. 125: Fix CPU type writeout in cfgfile.c (taken from WinUAE source). 126: Move the WOC demo BPLCON0 fix to compute_toscr_delay (Toni). 127: Added Toni's new disk patches, which include HD disk support by 128: Adil Temel. 129: Rewrote the memory and audio save/restore code. 130: Mask DDFSTOP with 0xFE, not 0xFC. 131: 9B0723 Yet another new and correct copper state machine (this time for sure) 132: Fix some AGA problems in DDF speedup code. 133: In gencpu.c, branch insns return a hardcoded cycle count; this had 134: not been updated for the CYCLE_UNIT stuff. Fixed. 135: xwin.c: If mouse is grabbed, we don't need mousehack. 136: Don't clear audio state if produce_sound == 0; this causes problems 137: if we want to turn the sound back on. 138: If an audio channel had a period of PERIOD_MAX, allow AUDxPER to 139: set its evtime back to a reasonable value. 140: Massive cleanup of memory initialization code; it will now use changed 141: prefs on reset. Added some memory options to gtkui.c. 142: Added Toni's state saving code, then added gtkui options and code to 143: initiate saving/restoring. 144: 9B0722 filesys.c: Fix writeout of hardfile params (Bernie [2]) 145: Add an A1000 Kickstart disk loader (Gerald Schnabel). Got rid of 146: the automount_uaedev code; we can detect the Kickstart version and 147: do the right thing. 148: Deleted a few unused variables (Toni) 149: Avoid aborting in decode_ham if Amiga code turns on the HAM bit but 150: has too few bitplanes (found by Toni). 151: Make the dummy mem bank return other values than 0; helps some 152: stupid memory detection code. 153: Implemented a little exec task lister for the debugger. 154: Added new debugger commands from Mark Cox. Improved his copper list 155: debugger by adding recorded timing information to it. 156: MOVE16 fixes from Gwenole Beauchesne. 157: xBCD fixes by Maik Qualmann, with some additional flag fixes by myself 158: (ABCD & SBCD behave exactly like on a 68000 now; dunno about NBCD). 159: 9B0520 AGA bscan2 fixes and disk.c kickstart speedup fixes from Toni. 160: Remove bogus changes I made to one of Toni's earlier disk.c updates. 161: Call RethinkICRA/B from INTREQ (suggested by Toni). 162: Properly save mixed_stereo setting. 163: NEGX uses X and Z (Bernd Roesch). 164: Danish keyboard support (Jesper Bojesen). 1.1.1.16 root 165: 9B0311 Repair "emulated but no output" sound setting. 166: 9B0310 Fix massive bug introduced in do_cycles_slow with the rescaling 167: changes. 168: CLXCON logic updated for AGA (Toni). Change meaning of collision_level 169: and add support for it in cfgfile.c. 170: 9B0309 Fix problem where a fsdb file could prevent deletion of otherwise 171: empty directory discovered by Torsten Enderling. 172: Rescale return values of CPU emulator functions. 173: 9B0225 Undo parts of the audio changes that made the "accurate" setting the 174: default. 175: 9B0221 Make fsdb_unix compile again. 176: 9B0219 Fix ddf for cases where start isn't aligned to fetchunit. 177: Fix some problems with the sound code going into infinite loops or 178: crashing. 179: Try to re-add Toni's ddf delay fixes properly. 180: Added a fix from Krister Walfridsson for X11 SHM code. 181: Rename OBJECT_NOT_FOUND to OBJECT_NOT_AROUND (not sure why, but the 182: win32 port does this; Fellow picked it up as well...) 183: Give in and allocate ainos with xcalloc. 184: Import fsdb_win32 code from Fellow. 185: Some tidyup and fixes in fsdb code. 186: Lose the lastdiv10 variable, and update CIA timers when reading them 187: (mostly by Bernie [2] Meyer) 188: Move reset_uaedevices and get_new_device to filesys.c. Add extra 189: parameter to get_new_device. 190: 9B0213 Fix mouse pointer jumping bug in X11 code (Ralf Hoffmann) 191: Scaled event handling by a factor of 512.

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