1.1.1.17! root 1: 9B0730 Some sprite state machine tweaks. Fix sprite vs. DIW comparison. ! 2: HAM linebuffer was too small by half - oops. ! 3: Make absolutely, positively sure that when hsync_handler calls ! 4: sync_copper_with_cpu, we don't take any invalid shortcuts. ! 5: 9B0729 Silly mistake - need to call flush_plane_data unless plfleft is ! 6: -1, even if no planes were enabled. ! 7: 9B0728 Small hack to reduce the time we lose with unnecessary ! 8: disk_doupdate_read calls. ! 9: Avoid calling flush_plane_data if we have no bitplanes enabled. ! 10: Tweak the SPCFLAG_INT handling to make "Delirium" demo work. ! 11: Limit rate of DDF warning messages. ! 12: Adjust display parameters so that things are shifted to the left ! 13: even more. ! 14: Fix (hopefully) CIA & blitter saving code. ! 15: 9B0727 Copper code reorganized; speedup code rewritten. Can now be ! 16: enabled with a GUI setting. ! 17: Fixed the delayoffset stuff. ! 18: 9B0725 AGA sprites, and some patches to sprite/playfield collision code, ! 19: mostly by Toni. ! 20: Fixed a small sprite restore problem; added missing code to map ! 21: fastmem banks when restoring them. ! 22: Some more state saving updates from Toni. ! 23: 9B0724 Fix a nasty bug in the copper SKIP instruction introduced by recent ! 24: changes. ! 25: Update the FAST_COPPER code. Not quite enabled yet. ! 26: More work on the memory configuration stuff. ! 27: Fix CPU type writeout in cfgfile.c (taken from WinUAE source). ! 28: Move the WOC demo BPLCON0 fix to compute_toscr_delay (Toni). ! 29: Added Toni's new disk patches, which include HD disk support by ! 30: Adil Temel. ! 31: Rewrote the memory and audio save/restore code. ! 32: Mask DDFSTOP with 0xFE, not 0xFC. ! 33: 9B0723 Yet another new and correct copper state machine (this time for sure) ! 34: Fix some AGA problems in DDF speedup code. ! 35: In gencpu.c, branch insns return a hardcoded cycle count; this had ! 36: not been updated for the CYCLE_UNIT stuff. Fixed. ! 37: xwin.c: If mouse is grabbed, we don't need mousehack. ! 38: Don't clear audio state if produce_sound == 0; this causes problems ! 39: if we want to turn the sound back on. ! 40: If an audio channel had a period of PERIOD_MAX, allow AUDxPER to ! 41: set its evtime back to a reasonable value. ! 42: Massive cleanup of memory initialization code; it will now use changed ! 43: prefs on reset. Added some memory options to gtkui.c. ! 44: Added Toni's state saving code, then added gtkui options and code to ! 45: initiate saving/restoring. ! 46: 9B0722 filesys.c: Fix writeout of hardfile params (Bernie [2]) ! 47: Add an A1000 Kickstart disk loader (Gerald Schnabel). Got rid of ! 48: the automount_uaedev code; we can detect the Kickstart version and ! 49: do the right thing. ! 50: Deleted a few unused variables (Toni) ! 51: Avoid aborting in decode_ham if Amiga code turns on the HAM bit but ! 52: has too few bitplanes (found by Toni). ! 53: Make the dummy mem bank return other values than 0; helps some ! 54: stupid memory detection code. ! 55: Implemented a little exec task lister for the debugger. ! 56: Added new debugger commands from Mark Cox. Improved his copper list ! 57: debugger by adding recorded timing information to it. ! 58: MOVE16 fixes from Gwenole Beauchesne. ! 59: xBCD fixes by Maik Qualmann, with some additional flag fixes by myself ! 60: (ABCD & SBCD behave exactly like on a 68000 now; dunno about NBCD). ! 61: 9B0520 AGA bscan2 fixes and disk.c kickstart speedup fixes from Toni. ! 62: Remove bogus changes I made to one of Toni's earlier disk.c updates. ! 63: Call RethinkICRA/B from INTREQ (suggested by Toni). ! 64: Properly save mixed_stereo setting. ! 65: NEGX uses X and Z (Bernd Roesch). ! 66: Danish keyboard support (Jesper Bojesen). 1.1.1.16 root 67: 9B0311 Repair "emulated but no output" sound setting. 68: 9B0310 Fix massive bug introduced in do_cycles_slow with the rescaling 69: changes. 70: CLXCON logic updated for AGA (Toni).

Delete USE_POINTER option; always use pointer. Don't fill 514: prefetch in m68k_setpc, do it in callers where necessary. Compile in 515: two versions of get_ixxxx, with different names for prefetch and 516: non-prefetch. Change gencpu.c to use these appropriately. 517: Don't generate 16 small CPU emulation source files. With a decent 518: machine it's no problem to compile all the code in one file. Also turn 519: off -O3 for gcc, -O2 does fine since all the necessary __inline__s are 520: there, and the compiler takes less memory that way. 521: Don't include <linux/joystick.h>, duplicate some definitions from 522: there instead. Makes configure.in simpler, too. 523: Fix Makefile.in/configure.in and a couple of other places to support 524: building in a separate directory (sort of; not complete yet). 525: Remove p2c.[ch] and genp2c when doing make clean. 526: Delete code to support Tcl/Tk and XForms GUIs. 527: 971215 More Amiga and BeOS patches from Sam and Christian. 528: 971205 Move some more code from custom.c to audio.c.

Improve hardfile support in 559: tui.c. 560: 971031 Offer "-U" only ifdef PICASSO96. 561: Add support for mounting multiple hardfiles in any order. 562: Don't reset sprite state in init_hardware_frame. Instead, allow SPRxPT 563: functions to set the state to SPR_restart in the vertical blanking 564: area. 565: 971030 Fix 8MB Chip RAM. 566: filesys_dev_storeinfo: New function and calltrap. Use it to store 567: per-unit data (which now includes geometry information) in the 568: parampacket. Modify filesys.asm to use it instead of trying to find 569: the values by itself. 570: 971028 "AMIROMTYPE1" has 11 characters, not 0. 571: 971027 Implement encrypted ROM features. Comment out non-working InvertRect 572: optimization. 573: 971026 Fix some problems in PlanarToDirect and CopyColorIndexMappingA2U. 574: 971022 Remove fixed paths in genp2c.c (oops...) 575: Some more XF86VidMode hacks. 576: Include target.h in sysdeps.h. Define PICASSO96_SUPPORTED for X11, 577: SVGAlib and Win32. Don't compile in Picasso support if this macro isn't 578: defined. 579: 971021 xwin.c: Picasso code wants to use bit_unit, not bitdepth. Also correct 580: byteorder (it's B8G8R8A8 from the Amiga's point of view). 581: Fix Picasso InvertRect function. 582: Half-hearted attempt at 24 bit support in the X11 version, with some 583: awful code in custom.c. 584: Make the X11/VidMode version try to resize the screen for Picasso mode 585: switches. 586: 971020 Delete option -5, make -4 take an argument. Disable z3fastmem and 587: Picasso emulation when using a 24 bit address space. 588: 971019 record_color_change: No need to remember a color table if the current 589: line hasn't been decided yet. 590: Add XF86VidMode extension support. 591: Integrate Stefan's Zorro III support, add support for up to 64MB fast. 592: xwin.c: Refresh the whole Picasso screen if there are Expose events. 593: Fix module length calculation for *Tracker modules. 594: Use a 32 bit address space by default if CPU_LEVEL > 1. New option -5. 595: 971018 Apparently it's not possible to turn on bitplane DMA in the middle of 596: the line, so call post_decide_line only when the number of planes is 597: modified, not in DMACON. 598: genp2c.c: New file, generates planar to chunky conversion routines. 599: Remove those which are now generated from custom.c. 600: 971017 Make row_map an array, not a pointer to one. 601: Audio periods may not be 0, so initialize them to 65535 in customreset. 602: Implement "S" command in the debugger. Add a bunch of module detection 603: routines. 604: 971015 od-linux/sound.c: If FRAME_RATE_HACK, reduce vsynctime a bit to give 605: the sound emulation more room to breathe. 606: 971013 Merge with Brian's latest Picasso code. 607: 971012 Fix a few more portability problems that showed up when compiling with 608: Watcom C.

Update od-win32 with latest code. 610: Remove fast_memcmp routine. 611: Include penguin.h before xwin.h everywhere. Declare a few semaphores 612: for multithreaded setups in xwin.h. Move inhibit_frame stuff to xwin.h. 613: 971011 gencpu.c: Don't generate labels without following statement. Don't 614: directly generate assembly statements if X86_ASSEMBLY, instead generate 615: code that uses macros defined in machdep/m68k.h. 616: 971008 xwin.c, svga.c, custom.c, uaelib.c: Add picasso96 code. Add Picasso 617: selection to configure. 618: Move common variables (mouse stuff, gfxvidinfo, xcolors) from graphics 619: files to custom.c. 620: memory.c: custom chip area isn't supposed to be mapped at 0x200000. Use 621: dummy bank for now. 622: od-linux/joystick.c: Open different devices for different joysticks. 623: From Win32 sources: set vsyncmintime in m68k_go. 624: 971005 genblitter.c: blitzero is initialized to 1, not to 0, so we need to 625: clear, not set it. 626: 970928 Add another user interface for X11 using libgtk+. 627: 970925 audio.c: For stereo sound, double all lookup table values. 628: Added (preliminary) win32.c. 629: 970923 DISK_check_change: Should call gui_filename when ejecting. 630: 970922 Fix od-linux/joystick.c compilation problem with recent kernels. 631: Merge results of the UAE meeting: 632: New serial code (Stefan Reinauer) 633: Expansion "test card" support (Stefan Reinauer) 634: New GGI code (Christian Schmitt), also configure/Makefile changes 635: to make it compile. 636: Fix 68020/FPU code. 637: Call do_mousehack before every read of the mouse position to get more 638: accurate values. 639: Add sd-file directory; add support for it in configure. 640: Add stereo support in audio.c, od-linux/sound.[ch], and main.c. 641: Fix copper problem: call decide_line in calc_copcomp_true; and if the 642: copper wouldn't wait normally (position reached), but the hardware is 643: fetching data in Hires 4 plane mode, delay until ddf stop. 644: t-ascii.h: Asciiart target understands "-x" parameter. 645: 970823 gencpu.c [X86_ASSEMBLY]: Turn input constraints for scratch into output 646: constraints. 647: 970626 Fix 24 bit address space logic (Mathias Ortmann). 648: Raise exception 3 for Bcc.L insns if CPU_LEVEL < 1. Reported by Stefan 649: Ropke. 650: Remove USER_PROGRAMS_BEHAVE for normal emulator. Remove hacks to 651: generate expanded CPU functions for specific opcodes. Replace with code 652: that reads an instruction count file and sorts gencpu output by 653: frequency of the called opcodes. 654: 970625 Calltraps (at least those with call_m68k calls in them) were broken by 655: the CPU emulator changes. Now use Axxx opcodes as calltraps. 656: Include pOS port by Samuel Devulder. 657: 970624 Solaris sound patches by Manfred Thole. 658: gencpu.c: The generated code shouldn't just check for odd addresses, 659: it should also call Exception... 660: 970622 gencpu.c: don't emit return statements; make code jump to a function 661: end label instead. Make genamode() check for odd addresses, also reduce 662: code duplication. Interpret getv parameter so that data is fetched if 663: getv == 1, and the address is checked if getv != 0. Remove exception 3 664: checks from get_long() etc. Get rid of buserr. 665: cpuopti.c: Make a few more checks whether optimization is possible. Add 666: code to undo GCC's epilogue scheduling. 667: newcpu.c: Split all the specialflag handling into new function. 668: Implement -w option as in Win32 port. tui.c: add it to misc menu. 669: 907621 Fix yesterday's CPU emulator changes.

Save cylinder/track number for the data 706: in the MFM buffer for each drive. Force rereads on disk insert and 707: write operations. In drive_fill_bigbuf(), do nothing if saved data 708: matches current. Fix disk change logic: give the program time to read 709: the change bit a couple of times before inserting a new disk. 710: custom.c: Fix really subtle bug: when deciding a line as border, 711: plfstrt/plflinelen were not set up properly, which could confuse 712: post_decide_line(), and eventually there would be lines decided as 713: playfield with plfstrt == 0, plflinelen == -32 ==> Bang. A related 714: bug was that setting DDFSTRT to 0 would result in both plfstrt and 715: plfstop having value 0. 716: gfxutil.c: Fix bug that could cause color values to go out of bounds. 717: xwin.c, svga.c: When dithering, color values were not doubled properly. 718: 970604 filesys.c: when deleting an a_ino, remove it from hash table (Mathias 719: Ortmann). In do_find(), if creating a file failed and we didn't have 720: an a_ino before, call delete_aino on the one we created. 721: More configure changes: Add $X_PRE_LIBS and $X_EXTRA_LIBS in some 722: places. See if MIT-SHM support for X will compile and link. Always 723: compile it in if it will. Turn DONT_WANT_SHM and LOW_BANDWIDTH into 724: run-time options (-T, -L). Use single line buffer when dithering and 725: in low-bandwidth mode (but in all cases there's a full buffer for the 726: X image). 727: memory.c: Don't map in custom regs at 0x200000 if chipmem_size > 2MB. 728: Split up init_sound(): new function setup_sound(). Make "-B" accept 729: minimum and maximum values as in Gustavo's latest patch. Add code to 730: tui.c to support changing buffer size, number of bits and frequency. 731: 970603 If using compiler, define NO_EXCEPTION_3 and NO_PREFETCH_BUFFER. 732: (bugreport by Raphael Poss). 733: GGI support from Christian Schmitt/Stefan Reinauer. More serial patches 734: from Stefan. 3 button joystick patch from Mathias. 735: Add linemem field to gfxvidinfo, for systems that don't want to keep 736: a buffer of the full screen. Adjust custom.c to use it instead of 737: bufmem if it's not NULL (mostly by Mathias). svga.c, xwin.c: Use single 738: line buffer in some cases. xwin.c: If USE_DGA_EXTENSION, undef 739: LOW_BANDWIDTH.

The new version 749: works by doing some heavy setjmp/longjmp magic and switching stacks. 750: With this, it's even possible to call things that Wait(), so use 751: the new functionality in gfxlib.c to call LockLayer() in WritePixel(). 752: 970531 Turn some inline functions in memory.h into macros. Get rid of 753: get_along and get_aword. Implement CIA A OVL bit. 754: main.c: Add missing close_sound() call. 755: Remove INTEL_FLAG_OPT, use X86_ASSEMBLY for everything. 756: tui.c/svgancui.c: Implement scrollable menus. Add code to select 757: video mode from a given list. Add "graphics_setup" call to graphics 758: specific files. Use it in svga.c to build a video mode menu. 759: Fix bug in svga.c that would crash non-linear modes. 760: disk.c needs to include gensound.h and sounddep/sound.h. 761: Fix bug in fuzzy_memset. In pfield_init_linetoscr, always adjust ddf 762: values if lores hack is being used. 763: 970530 Apply some patches by Samuel Devulder. 764: 970529 filesys.c: In "Houston, we have a problem" case, do not only delete 765: the oldest ExKey, but also use it instead of random memory for the 766: new one. Attempt to reduce the number of lost exkeys by allocating 767: them in action_examine_next instead of action_examine_object. 768: Initialize the "uniq" field of unit->rootnode. 769: Attempt to speed up sprite drawing loop. 770: Implement sprite<->sprite collisions. 771: Get rid of -Wtraditional. 772: 970524 New config option NO_PREFETCH_BUFFER. Emulate 16 byte prefetch if 773: unset. 774: For exception 3, the stack frame seems to be: 775: (saved SR).w, (faulting address).l, (faulting instruction).w, 0.w, 776: (pc at fault time).l. Make everything that could generate this fault 777: handle it properly. That got Cybernoid II working! 778: 970523 Makefile.in: Make sure $(DEBUGFLAGS) is used for CPU emulation files. 779: memory.c: Don't map chipmem at 0x200000, use custom chip bank for now. 780: 970507 configure.in: Mutate ac_cv_c_inline=no to ac_cv_c_inline= 781: Check for tcgetattr, <sys/termios.h>, cfmakeraw, <sys/ioctl.h> 782: Check for sem_init in -lposix4 (Marc Zimmermann) 783: serial.c, cia.c, cia.h, serial.c: changes (Stefan Reinauer) 784: Make disk gap 360 (Michael Krause) 785: 970404 In configure, check for features.h before including it in test program. 786: 970401 New option -4. Bugreport by Mirko Viviani. 787: 970324 Petter Schau says the exception frame for Bus Error and Address Error 788: is 14 bytes, not 6, on the 68000. Change Exception() accordingly. 789: It's *** OUCH *** day! Make hardfile beginio return the correct value. 790: Also load execbase before calling ReplyMsg(). 791: It's *** OUCH *** day again! The filesystem asm code was an odd number 792: of bytes, leaving the hardfile code unaligned. 793: 970318 custom.c: Rename spron to sprst, and use new variable spron to indicate 794: for which sprites the sprite pointer registers have been written. Don't 795: do sprite DMA if spron==0. (The problem was that some programs write 796: SPRxCTL and then SPRxPT, which used to set the sprite state to 797: SPR_restart, but it must be SPR_waiting_start.) 798: Turn a few m68k_reset()s into uae_reset()s. 799: New variable nr_joysticks. Delete joystickpresent. New arg "nr" for 800: getjoystate() and read_joystick(). 801: New extra keycode AK_RCTRL. Handle multiple joysticks & different key 802: replacements in keybuf.c/custom.c. Make tui.c handle all the settings. 803: 970310 od-linux/joystick.c now compiles again without the joystick header. 804: Fix some problems in configure; also check whether [n]curses.h defines 805: attr_t. Keep count of warnings and errors during configuration and 806: print a hopefully helpful message at the end. 807: disk.c sanitized by Mathias Ortmann. 808: Change the replacement getopt around a bit. 809: execlib.c, timerdev.c: Files removed. This will never be compatible 810: enough. Also remove related code (several SPCFLAGs, etc.) 811: Make main.c a bit nicer by introducing additional defines for the t-* 812: files. Also canonicalize the .uaerc file on all systems, eliminating 813: lines starting with '#' in the process. 814: Remove code in autoconf.c to set up 8MB chip; move it to filesys.asm. 815: Try doing the copper end-of-line hack in copper_memory_cycles(). 816: Disable the copper speedup hack. 817: 970309 Add a small, dumb hash table to struct _unit to speed up repeated 818: aino lookups. Delete aino in action_delete_object(). Move children in 819: action_rename_object(). In action_examine_next(), call new function 820: lookup_child_aino_for_exnext() which behaves more or less like 821: lookup_child_aino(), except it uses new function get_aname() to 822: translate filenames. 823: More portability fixes. New links set up in configure: sounddep, 824: target.h. All machine-dependent and joystick code removed 825: from os.c, renamed to audio.c. os.h renamed to audio.h, joystick stuff 826: moved to joystick.h. New directory targets/. 827: missing.c: New file. 828: 970308 Rewrite filesystem. Now it keeps one unique "a_inode" structure for 829: every object in the filesystem. This contains Amiga name, native 830: name, Amiga permissions, lock counts and several links for building 831: a tree structure. Keys are now made only for files which need a fd 832: and a file position. 833: Treat invalid locking modes als shared. 834: Comment out the code using readdir_r because that function appears 835: to be broken in glibc-2.0.1. 836: Clear RES2 in all packets before handling them. 837: Give mousehack the same task priority as the input.device. 838: Fix (?) some silly bugs in disk.c. 839: 970307 Include some Acorn port code from Peter Teichmann. 840: Yet Another Serial Diff from Stefan. 841: 970306 filesys.c: Don't just crash if lookup_key() has no success. 842: action_find_write() is supposed to create the file if it does not 843: exist. 844: 970305 More DOS patches. Make the Makefile parallel-make safe. 845: svgancui.c: Do cyclic search if character is typed in file selector. 846: my_alphasort(): New function (work around glibc bug) 847: custom.c: Fix error in yesterdays change. 848: filesys.h: New file. 849: 970304 New serial patch from Stefan and Christian. 850: Remove the assembler code to generate inputevents. Instead, add a new 851: Amiga C program ("mousehack") which does the trick. New function 852: mousehack_helper() in custom.c, activated by calltrap 0xF0FF70. 853: Mouse default is now always normal_mouse, not follow_mouse. 854: Do disk change checks only every 1/2 second. disk.c: Reverse 855: nodskchange to dskchange, and make sure there has been a step with the 856: drive empty before calling drive_insert() from DISK_check_change() (but 857: this _still_ doesn't work. Arrrghh). 858: 970303 filesys.c: Initialize _all_ of struct _unit in startup_handler(). 859: Remove message_lock and friends and use new variables cmds_sent, 860: cmds_acked and cmds_completed to determine when to send dummy messages. 861: Changed examinekey handling so that "dir all" on a large tree doesn't 862: crash anymore (it used to reuse the top-level exkeys which were still 863: in use after a wraparound). Don't allocate examinekeys if we're 864: examining files. 865: Check for readdir_r in configure. Use a wrapper my_readdir() around 866: either readdir or readdir_r. 867: Call filesys_reset() also from filesys_diagentry(). 868: Get rid of most of uaelib.c. Now there isn't a library, just a calltrap 869: at 0xF0FF60. Changed uae_pragmas.h accordingly and recompiled uaectrl. 870: Added a bunch of "volatile"s in various places in filesys.c and 871: penguin.h. 872: Make the filesystem reset-safe in the threaded case (paranoia changes). 873: Check disk changes only every 1/10 second in vsync_handler(). 874: Add assembler code to generate InputEvents once every vblank to 875: filesys.asm. (Doesn't work yet.) 876: 970302 filesys.c: Get rid of DosPacket type, pass pointers into Amiga memory 877: instead. Use GET_PCK_* and PUT_PCK_* macros to access fields. 878: Start making filesystem code thread safe & multithreaded. Move static 879: variables from some functions into struct _unit, likewise the key 880: and exkey variables. Add code to filesys.asm to queue commands which 881: did not complete and to reply to them later. Do multithreading if 882: compiled with SUPPORT_THREADS. See source for details. 883: Change hardfile and uaelib code not to call 68k routines. Make emulator 884: traps more efficient (no need to save regs, don't need SPCFLAG_EMULTRAP 885: anymore). 886: 970301 Fixed ncurses.c so it works with currprefs. 887: filesys_reset(): New function, called from customreset(). 888: Changed source layout. Break up machdep into machdep, osdep and 889: threaddep. 890: penguin.h: Now supports arbitrary types in pipes. 891: Changed filesys.c so that no 68k code is called from native C code. 892: filesys.asm, filesys.sh: New files. filesys.asm contains some 893: startup code and the main loop for the filesystem. Several locks 894: are allocated by the assembler code for use by the C code. 895: DOS_AllocMem(), DOS_FreeMem(), make_dev(), build_parmpacket(), 896: filesys_init(): Functions removed. 897: 970228 ncurses.c: Fix problem in b/w modes. 898: finish_drawing_frame(): Don't need to draw lines in multipenguin mode. 899: Move all options into new struct uae_prefs. New variables currprefs, 900: changed_prefs. 901: svgancui.c, tui_filereq(): If user presses a key, start search at 902: current position, not at the beginning. 903: DISK_check_change(): new function, compares currprefs with 904: changed_prefs and handles diskchanges if they differ. Called from 905: vsync_handler(). 906: DISK_validate_filename(): new function, checks whether a file exists. 907: Modify svga.c and tui.c so that F11 now brings up a limited UI. 908: 970227 Reimplement Mathias Ortmann's frame rate hack: New option HAVE_RDTSC 909: in config.h. New typedef frame_time_t. New variables vsynctime and 910: vsyncmintime. New function machdep_init() in md-*/support.c which 911: sets up vsynctime in the md-i386-gcc and md-i386-linux cases. Use 912: all of those in events.h, do_cycles() to determine whether to spend 913: more time on the CPU emulation. 914: Add missing "int i;" to xwin.c, init_colors(). 915: Unroll some loops in sample_*handler(). 916: Improve quitting/resetting behaviour: Move quit_program from GUI 917: specific files to main.c. New functions uae_reset() and uae_quit(), 918: quit_program is now handled in vsync_handler() and m68k_go(). 919: New variable sample_evtime, used in customreset() and set up in 920: init_sound(). 921: 970226 Solaris sound update from Manfred Thole. 922: keybuf.c: Decided that it doesn't need locking after all. 923: Add a bunch of Gustavo's latest diffs. (I hate CR characters!) 924: Move gfxvidinfo from all the target-specific files to custom.c 925: More Win32 stuff: New function notice_new_xcolors(). 926: 970225 configure.in: In shell string comparisons, always put spaces around = 927: Add warning about standard SVGAlib being incompatible with 928: LinuxThreads. 929: os.c, SOLARIS_SOUND: Remove reference to obsolete variable smplcnt. 930: Two new variables sound8_base and sound16_base. 931: sysdeps.h: Split off some stuff into md-amiga/amiga-kludges.h. Also 932: make the main types now uae_u32 and variants instead of ULONG, etc. 933: Convert some files to use the new types. 934: cia.c: use int/long instead of ULONG/UWORD/etc for most static vars. 935: xdebug.c: Some cleanup. 936: md-i386-linux/penguin.h: Fix bug. Add "chunks" parameter to 937: init_comm_pipe. Use it to decide in write routine whether to signal 938: the other thread if it's waiting. Add no_buffer parameter to 939: write_comm_pipe_int. 940: Start adding Mathias Ortmann's Win32 patches. 941: md-i386-win32: New directory 942: include/sysconfig.h.win32: New file 943: custom.c: is_lastline: new variable, set in hsync_handler(). 944: sysdeps.h: Make it possible for system specific code to say that 945: POSIX/ANSI stdio/malloc functions aren't present and are defined 946: by a system-specific file instead. In filesys.c, don't reference 947: errno if DONT_HAVE_POSIX is defined. 948: readcpu.h: Kludge around the fact that Messysoft C apparently doesn't 949: handle enums properly. 950: newcpu.c/sysdeps.h: Preprocessor magic for 64 bit constants to get 951: around a problem with MS C. 952: md-*/penguin.h: Add dummy definitions for semaphores. 953: keybuf.c: Use semaphores to synchronize access. 954: os.c, win32 sound stuff: add memcpy avoidance code. 955: 970221 X86.S: Don't use .type ifdef USE_UNDERSCORE. 956: Move thread support configuration to configure from config.h. Change 957: pipe implementation to use POSIX semaphore functions. 958: 970217 From Samuel Devulder: Fix off-by-one error in LINE_TO_SCR, EHB case. 959: 970215 customreset(): Initialize current_colors.color_regs to invalid values 960: [reported by Samuel Devulder]. config.h: Uncomment ECS_DENISE [reported 961: by Mathias Ortmann]. Add ami-win.c and custom.c patch from Samuel 962: Devulder. 963: 970213 disk.c: Set FLOPPY_SPEED to 3 964: custom.c: SPRxCTL_1(): if spron was SPR_restart set it to 965: SPR_waiting_start. do_sprites(): don't do that. 966: SPRxPT{H,L}: Call decide_line(). 967: 970210 custom.c, X86.S: Do LORES_HACK for dual playfield screens. Plug memory 968: leak in custom_reset(). Fix pfield_draw_line() not to do so many 969: multiplications. Make line_changed a char array. In remember_ctable(), 970: remember comparison results also if negative. 971: In 8 and 16 bit graphics modes, use the high parts of the color values 972: to duplicate the actual values. This saves a lot of code in the 973: hdoubling routines. Add a special fill_line in the X86_ASSEMBLY case. 974: Check for glibc-2 and libpthread in configure. 975: options.h: In fuzzy_memset(), do rounding slightly more conservative. 976: Add tons of new keycodes to svga.c 977: In record_color_change(), also check if vertically outside DIW. 978: New variable hdiwstate, to represent the horizontal DIW state machine 979: (thanks Petter!) Handled in reset_decisions(), finish_decisions() and 980: decide_diw(). 981: 970209 Change ncurses.c not to do so many multiplications/divisions. Add bold 982: character support. Add color support. Make configure recognize 983: --without-svgalib and enable ncurses.c in that case. 984: 970208 X86.S, custom.c: Do LORES_HACK for EHB screens also. 985: New function write_log(); convert some fprintf(stderr, ...) calls. 986: 970207 Argh, Linux/i386/ELF check in configure got broken by latest sh-utils. 987: In disk.c, drive_reset(), clear nodskchange flag. 988: 970206 Sprite fix from Mathias Ortmann: _really_ get rid of SPR_vtop, and 989: replace all uses by SPR_stop. 1.1.1.2 root 990: 970204 Disk change fix from Mathias Ortmann. 991: 970203 New file ncurses.c, from Samuel Devulder. 992: Disabled Exec stuff completely. Now it isn't even compiled in anymore. 993: 970129 Changes from Samuel Devulder for Amiga and Christian Bauer for BeBox. 994: 970122 Reorder the set_planes_unaligned functions so that better code is 995: generated. Remove the or_planes_unaligned functions, add a parameter 996: do_or to the set_planes functions and rely on the compiler to optimize 997: the additional if away. 998: post_decide_line() can now turn DMA off early. 999: Make struct flag_struct 64 bits large for i386 systems, so we can use 1000: long move insns without clobbering the X flag. 1001: "make clean" should delete machdep/support.o. 1002: Maybe we do need SPR_vtop after all - undo 970120 change. Instead, 1003: comment out the code that clears the pos and ctl words at vsync time. 1004: In xwin.c, restrict window height to 300 or 600 depending on linedbl 1005: mode. 1006: 970121 Get rid of SPCFLAG_BLIT, call do_blitter() directly. 1007: In finish_decisions(), don't check for sprite draws in the border. 1008: Reimplement the SMART_UPDATE define so that the memcmpy() overhead can 1009: be avoided by not setting it (but this usually loses). 1010: Detect 7 lores planes in BPLCON0() and change to 6 to avoid memory 1011: clobbers. 1012: In pfield_draw_line(), do memcpy linedoubling after handling the line 1013: to be doubled, not when we see a LINE_AS_PREVIOUS. Get rid of prev_ypos 1014: parameter. 1015: Add special code for bpldelay1 == bpldelay2 to the UNALIGNED_PROFITABLE 1016: code. 1017: In pfield_init_linetoscr(), when delays 1 and 2 differ, clear the areas 1018: which are covered only by half of the planes at the start and end of 1019: the DDF area. 1020: Replace FASTER_CPU and LINUX_SOUND_SLOW_MACHINE with M68K_SPEED. 1021: Replace fast_unaligned_memset macros with fuzzy_memset; use this also 1022: in pfield_init_linetoscr(). 1023: Use real (PAL) vblank end in do_sprites(). 1024: 970120 Mask out high byte in DDF{STRT,STOP} 1025: Oops, forgot about long frames while calculating the bounds of all the 1026: maxvpos*2-sized arrays. Increment them all by two. 1027: Try to detect empty sprites before recording them for the drawing code, 1028: but be careful not to hurt attached sprites. 1029: From Paul Kienitz: hack for keyboard code in cia.c to work better with 1030: newer Kickstarts; small cleanup in cpuopti.c. 1031: Undo yesterday's change in copper_memory_cycles(), instead call 1032: decide_line() each iteration and test whether copper_cycle_time == -1 1033: to determine whether we're vertically in the DIW. 1034: calculate_copper_cycle_time() could get astronomical plane counts due 1035: to missing masking operation. 1036: No need to put the copper to sleep for one memory cycle after a WAIT, 1037: merge that with the two cycles for the next instruction. 1038: Get rid of SPR_vtop, no longer needed (it was unnatural anyway) 1039: 970119 Implemented alternate pfield_doline functions that access the apixels 1040: array at unaligned addresses; conditional on UNALIGNED_PROFITABLE. 1041: Move LORES_HACK from config.h to custom.c. 1042: Fix loop exit test for pfield_linetoscr_hdouble_asm8(). Clear the 1043: right parts of apixels in pfield_init_linetoscr() when LORES_HACK is 1044: enabled. 1045: Get rid of bordercol array: the decision-making code should handle 1046: lines in the border correctly by setting line_changed. 1047: Disable bitplane DMA if more than 4 hires bitplanes are set in BPLCON0. 1048: Fix some more copper timing inaccuracies: used to test 1049: thisline_decision.which without calling decide_line() before. 1050: 970118 Now remember BPLCON1 changes during data fetch. New functions 1051: decide_delay(), pfield_adjust_delay(); new fields in struct drawinfo 1052: and new variables next_delay_change, delay_changes. 1053: Forgot to set copstate to COP_morewait in one case in do_copper(). 1054: Add a kludge that checks for copper position 0xDC and changes it to 1055: 0xDE. 1056: Restore equality test for vertical sprite positions. Disable sprite 1057: DMA before the end of the vertical blank area. 1058: Mask not only the positions, but also comparison values in 1059: calc_copcomp_true(). 1060: 970117 Change custom_bput to put the byte value in each half of the word that 1061: is put. 1062: 970116 disk.c: Set the gap between sector 11 and 0 to 380 words. Andromeda's 1063: "Seven Seas" demo expects at least 320. Make the KILLEHB bit 1064: conditional on AGA_CHIPSET. Decide BPLCON1 (scrolling delays) in 1065: decide_diw(). Fix off-by-one errors in the very_broken_program case 1066: of decide_plane(). Fix aspect calculation when horizontal resolutions 1067: differ. Simplify copper horizontal comparison logic slightly. 1068: Fix divide by zero errors when reading from empty floppies. 1069: 970115 pfield_draw_line(): Check for frame_redraw_necessary also for border 1070: lines. New global variable pfield_last_drawn_line, used to implement 1071: clever Y centering. Make the KILLEHB test conditional on ECS_AGNUS. 1072: Move joystick and sound initialization before gui startup. Adapt tui.c 1073: so it understands the gfx_requested_* options. 1074: We can't always avoid clearing pixdata.apixels if DIW is larger than 1075: DDF. There may be sprites in the area outside DDF, but inside the DIW, 1076: so we can't just adjust linetoscr_diw_{start,end} blindly in 1077: pfield_init_linetoscr() [Sanity Arte demo]. 1078: 970114 Bebox diffs from Christian Bauer. 1079: Support for Symmetric Multi Penguins under Linux (start second thread 1080: with clone and use some pipes for communication - rather simpleminded 1081: for now). Rework do_flush_line() and do_flush_screen() so that X 1082: libraries are only called from the first thread. 1083: Eliminate valid field from struct decision (set which to -2 instead of 1084: valid = 0) 1085: Fix definition for gui_filename() in xdebug.c to use const char * for 1086: the second parameter. Remove CRs from disk.c (now how did they get in 1087: there??). Likewise for cpuopti.c. 1088: 970113 When post_decide_line() detects mid-line DDF change, must adjust 1089: bitplane pointers in decide_plane() also. Make plfstrt the earlier a 1090: position in this case, and adjust bitplane pointers/modulos 1091: accordingly. 1092: current_hpos() isn't what GCC calls a constant function. 1093: Replace line_drawinfo[current_change_set] with new variable 1094: curr_drawinfo throughout. Likewise for new variables prev_drawinfo, 1095: {curr,prev}_{color_{change,table}s,sprite_positions}; all initialized 1096: in init_drawing_frame (). Turn line_data into a 2dim. array, do some 1097: CSE/SR on line_data[lineno] in pfield_doline_{l,h}() and 1098: decide_plane(). Make some custom registers unsigned int instead of 1099: UWORD. 1100: calc_copcomp_true(): Masking with 0xF000 isn't likely to give 0xC0000. 1101: Comment out bplcon{3,4} from struct decision. 1102: 970112 filesys.c, action_set_protect(): if __unix is defined, check whether 1103: user wants to change directory protection, and if so, force rwx to be 1104: the new protection. 1105: Force sane window sizes in xwin.c, and set width/height from mode specs 1106: in svga.c. 1107: Implement LORES_HACK compile-time option. 1108: Whee, there _are_ broken programs that enable bitplane DMA in the 1109: middle of the data fetch area, draw half a picture on the first line 1110: and the full picture on all subsequent lines. New function 1111: post_decide_line(), called from BPLCON0() and DMACON() which tries to 1112: detect this case and turns the decision from border to playfield if 1113: necessary. 1114: New arrays, sprvstart and sprvstop, calculated in SPRxPOS and SPRxCTL, 1115: and used by do_sprites. Handle sprites with vstart == vstop correctly. 1116: Sprite vpos comparisons are now done with <= , not ==. 1117: _Now_ the X86-specific linetoscr routines do their masking correctly. 1118: configure: If we have GCC, #define GCCCONSTFUNC as __attribute__ 1119: ((const)) 1120: 970111 Eliminate can_draw from struct decision. 1121: Change vertical DIW code; use enum of two states (waiting for start and 1122: for stop) which is updated in decide_line(). Lines during the wait for 1123: stop phase are decided as border. No data is fetched outside the 1124: vertical DIW. 1125: Optimize copper memory cycle calculation a little: the new variable 1126: copper_cycle_time is set to a time >= 0 if this time is constant 1127: (i.e. 2). Calculated whenever DMA, BPLCON0, or DIW state changes. 1128: blitter.c, genblitter.c, custom.c: For BLTBDAT, follow the HRM which 1129: says that immediate data is shifted as soon as it is written. This 1130: seems to be wrong for the A channel, though. Also, don't change prevb 1131: during blitter loops if DMA B is off (Sanity Arte). Turn FAST_BLITTER 1132: stuff into run-time option "-n", and eliminate the ancient blitting 1133: code (former FAST_BLITTER == 0). 1134: Big OOPS: Copper move checked copcon, but there was no COPCON function 1135: so it was always zero -> copper-controlled blitter never worked. As a 1136: speed optimization, recognize 00010000 copper commands and put the 1137: copper to sleep until the blit is finished. 1138: Slow down the blitter in decide_line() if bitplane DMA steals blitter/ 1139: copper/CPU cycles (but this code is commented out for now). 1140: 970110 New function pfield_init_linetoscr(). Move calculation of diw_end and 1141: diw_start values there from x86-specific code. Also use DDF values to 1142: determine where data in pixdata.apixels is valid. The x86-specific 1143: linetoscr routines now only do the alignment masking (and they now do 1144: it correctly, too). 1145: Got rid of the display-related contents of struct draw_info, make 1146: static variables and them initialize from pfield_draw_line() only when 1147: necessary in function pfield_expand_dp_bplcon (). Get rid of the four 1148: saved_* arrays, remember line_drawinfo instead now that it's smaller. 1149: Color compare avoidance didn't work because color_src_match didn't get 1150: set when a compare was successful. Fixed. 1151: Reorder parts of the decision-making code so that less redundant checks 1152: are performed. 1153: Add clever x centering. Change "-O" option parameter format. 1154: In md-i386-linux/support.c, memcmpy(), do memcmp() first, then switch 1155: to a plain memcpy routine once we find the first difference. 1156: Patches from Stefan Reinauer/Christian Schmitt for 1157: xdebug.c/configure.in 1158: New uae-ui.tk from Volker Zota. 1159: Add --enable-profiling to configure.in. 1160: Check for period==0 in AUDxPER() was accidentally commented out - 1161: revert. 1162: 970109 Some tweaks in X86.S, plus a new option X86_PPRO_OPT to use movzbl 1163: instead of xorl/movb when possible. 1164: Fix maxline calculation in finish_drawing_frame(). 1165: Make next_lineno always a valid array index. Decrease minfirstline to 1166: 21 (NTSC vblank end). New option -O to specify display parameters, 1167: supersedes -d and -C which will be removed eventually. Differentiate 1168: between line doubling and aspect correction. Put aspect correction code 1169: in custom.c. 1170: Remove some more unused stuff from custom.c. 1171: Fix Makefile problems when cpuopti isn't used. 1172: 970108 use_lores isn't initialized before custom_init(), setup lores_frame and 1173: friends in customreset(). Optimize spixstate clearing. Optimize border 1174: drawing with copper color changes (use fill_line instead of linetoscr) 1175: Fix the sprite DMA logic, it now works with the Interference demo. 1176: Silly bug: Sprite 7 never got displayed (introduced sometime last week) 1177: Implement USER_PROGRAMS_BEHAVE for normal (non-compiler) CPU emulation. 1178: Add most of Gustavo's last patch (new dir md-i386-dos) 1179: 970107 Finish rewriting most of the drawing code in custom.c/X86.S. See 1180: README.PROGRAMMERS and source for details. Improvements include better 1181: copper precision, better interlace support, hopefully much less bugs 1182: and not too many new ones. 1183: Remove calc_adjustment() and gfxvidinfo.x_adjust; replace with code in 1184: custom.c that looks at gfxvidinfo.follow_diwstop (new field) 1185: Some operations (like EHB playfields) now have a higher penalty than 1186: before, the assumption being that these are rare and the normal case 1187: runs faster if it doesn't have to care too much about exceptions. 1188: Fix sign mismatch bug in BPL1MOD() and BPL2MOD(). 1189: 970104 Move x_ShowEA() from xdebug.c in newcpu.c, rename as ShowEA(). 1190: 970102 Add check for XK_W to decode_es() in xwin.c. 1191: New uae-ui.tk from Volker Zota. 1192: 961218 Add a patch by Bernie Solomon to overcome a problem with K&R compilers. 1193: Change X86.S in a way that may make it either faster or slower. 1194: Fix ADF_EXT1. 1195: 961217 #ifdef XK_dead_*, since Solaris doesn't have it. 1196: 961202 Fixed joystick.h problem in configure. X11/DGA support from Kai 1197: Kollmorgen. 1198: 961117 Some fixes in svgancui.c. 1199: 961112 Gustavo's latest patch, with GUS support for DOS by Michael Sontheimer. 1200: Add menu browsing to tui.c/svgancui.c 1201: 961107 Fix m68k_areg and m68k_dreg macros (put args in parentheses) 1202: Initialize gfxvidinfo.maxlinetoscr in xwin.c (found by Sam Devulder) 1203: 961104 svgancui.c tui_refresh() routine tweaked to work with the non-standard 1204: ncurses that came with my new SuSE-Linux CD. 1205: 961031 Added Christian Schmitt's xdebug.c (disabled for this release) 1206: 961024 Module search function from Michael Krause. 1207: 961019 Add Samuel Devulder's Amiga patches. 1208: 961018 Don't use -lm on NeXTStep. 1209: 961017 configure checks for -lforms. 1210: 961016 Ian Stephenson's new NeXTwin.m. Make CLXDAT return 0 (no collisions) 1211: transdisk and transrom patches from Rodney Hester. Don't warn about 1212: 256K Kickstarts. Check diskfile sizes and try to determine whether it's 1213: a normal or a HD diskfile. No HD drive identification yet (is it 1214: different?) 1215: 961013 Corrected lots of bugs in the return address stack. Fix some errors in 1216: the compiler memory management. Use the "locked" flag for hash entries 1217: differently, and don't enforce it on a cache flush. Compile JMP to a 1218: constant address. 1219: 961012 Remove regs from cache before sign extending them for ADDA, MOVEA and 1220: similar things. Compile NOPs to nothing. Implement variable shifts/ 1221: rotates. Most shifts clear the V flag: Handle this in the compiler by 1222: some extra magic sequences after shifts or in the CC_AFTER_RO case in 1223: flush_cc_cache(). 1224: Implement a stack containing return addresses and their hash entries, 1225: and compile JSR (to constant addresses)/BSR/RTS instructions inline. 1226: 961011 compiler.c: Several bugs introduced in the last two days fixed. 1227: New function compile_note_modify() which is used when an ea is 1228: modified. This replaces calls to storeea with eaino_s == eaino_d. 1229: Bah, the 386 doesn't set flags on a NOT. Use CC_TEST_REG again. 1230: Do flag life analysis until no more changes are found. 1231: Make sure all "data" parts of EAs are locked exclusively (esp. for 1232: LEA, PEA) 1233: 961010 compiler.c: Finish yesterdays changes. Get rid of reg/offset 1234: bookkeeping in m68k_compile_block(), keep the information in struct 1235: ea_info instead. Rewrite all instructions to use the new fetch and 1236: store routines. 1237: Don't force a byteorder conversion in sync_reg() if the reg doesn't need 1238: to be written back. Don't do a SAHF or equivalent in compile_condbranch 1239: if we are doing a BRA or BF. 1240: Don't use CC_TEST_REG for NEG and NOT (this was inefficient for NOT and 1241: wrong for NEG). 1242: 961009 compiler.c: Two types of locks for registers; shared and exclusive. 1243: Implement better EA fetching and storing routines. For pdi addressing 1244: modes, lock the necessary registers shared before calling prepareea. 1245: Unlock those registers again in generate_possible_exit(). 1246: 961008 MOVEM instructions in the compiler to an absolute address could have 1247: caused random memory corruption. 1248: 961007 Spanish keyboard support for X by Ruben Martinez. Some configure fixes 1249: (don't assume current dir is in path, don't assume ncurses.h exists if 1250: libncurses does). 1251: If we're calling 68k code from an emulator function, don't use compiled 1252: code. 1253: Add a compilation option USER_PROGRAMS_BEHAVE (for compiler). Make 1254: compiler hash table larger. 1255: 961004 Fix typo in configure.in. 1256: Modify the compiler so it doesn't ever throw away code, unless it's 1257: necessary for a cache flush. 1258: Didn't quite squash the compiler flag bug yesterday. Try again. 1259: In filesys.c, do_find(), add a parameter fallback that indicates that 1260: the open should be retried with O_RDONLY if it failed with O_RDWR. 1261: Use this in find_input(). This fixes problems with r/o files on r/w 1262: volumes. 1263: 961003 Play around with the x86 specific memory access functions. Problem: 1264: __attribute__((regparam)) isn't reliable, and it seems that that's a 1265: rather hard to fix bug in GCC. Add some alternatives to 1266: md-i386-linux/memory.h; these aren't used yet though. 1267: Huh, the compiler was completely wrong about the flag needs of 1268: conditional instructions. I wonder how it could work at all... 1269: Remove a and d arrays from struct regstruct; replace with array regs 1270: with 16 elements. This allows better code for get_disp_ea() 1271: 961002 BeBox diffs from Christian Bauer. Move all code from main() to new 1272: function real_main(). 1273: 961001 Use do_get_mem_*() functions for nextiword(), nextilong() and new 1274: function nextibyte(). 1275: 960930 genblitter optimizations: Don't generate expressions in genblitter, use 1276: a second program called gengenblitter to generate a table of 1277: expressions for genblitter to use. gengenblitter knows about a lot of 1278: rules to simplify expressions. Some other tweaks to make GCC output 1279: better assembly for blitfunc.c. 1280: 960927 Turn off LED() in xwin.c (may fix SunOS joystick emulation problems) 1281: Call XFlush() and XSync() when exiting. 1282: Add some DOS patches. 1283: Add hooks in filesys.c to support filesystem units in a GUI. Use them 1284: in tui.c. Bugfixes in svgancui.c. Change the way tui_refresh() works. 1285: New option "-A". 1286: 960925 For read-only filesystems (CD...), use O_RDONLY in action_find_input. 1287: 960923 Save options file even if rename fails. 1288: Mirror address space every 16MB like we used to (got turned off by 1289: accident). 1290: Move some checks out of options.h into configure. Set up md-* 1291: directories with machine-dependent stuff in them; configure creates 1292: a link called machdep to the appropriate one. 1293: 960918 Solaris sound update from Manfred Thole. 1294: 960917 Add a timer.device replacement (buggy). 1295: 960916 Tristan Cavelier's french keyboard patch. 1296: Apply ReadTheSpecsBeforeYouWrite(tm) technology to AddPort(). 1297: Implement RemPort(), GetCC(). 1298: 960915 Tighten up some of the return values in Exec. 1299: 960914 EXEC: Implement RemTask(), ObtainSemaphoreList() and 1300: ReleaseSemaphoreList(). Set up more fields of the ExecBase properly 1301: and Enqueue it in the library list. Make InitResident call AddLibrary 1302: when appropriate (otherwise, intuition is never put into the library 1303: list). Fix major braino in Obtain/ReleaseSemaphore() (tried to Enqueue 1304: tasks into two lists). Make OpenLibrary() honor the version parameter. 1305: 960913 EXEC: Idle task now runs in user mode (abuse 0xFF0D as second STOP 1306: instruction). Make EXEC_IntTrap perform the RTE before trying to 1307: schedule. 1308: 960912 Solaris sound didn't compile. So much for making blind changes without 1309: being able to test them. 1310: 960911 As soon as you compile it under Solaris, it bombs... Now check that the 1311: hardfile exists before determining the size in main.c. 1312: execlib fixes: Set master DMA enable bit at startup, fix interrupt 1313: code to survive an interrupt that occurs before the proper SetIntVector 1314: call. Implement RawDoFmt(), CloseDevice(), CloseLibrary(), 1315: FindResident(). 1.1 root 1316: 960905 Lower 8 bits of POTGOR should be 0. 1317: 960904 Implement MULU, MULS, ADDX and SUBX in compiler. 1318: 960903 ncurses interface works. DOS people: please use the new portable tui.c 1319: and turn dos-ui.c into a frontend for conio.h, similar to svgancui.c 1320: In xui.c, unlink the temporary files ASAP. 1321: Two new command-line options, "-o" and "-G". 1322: Get rid of sz_unknown. 1323: compiler.h, compiler.c: New files. 1324: filesys.c, action_read(): Added a hack to test whether the first four 1325: bytes read from a file a file contain 0x000003F3 (HUNK_HEADER), in 1326: which case there's probably a LoadSeg() call going on and we ought to 1327: flush the cache. Also, use the fact that memory is now linear. 1328: 960902 Struggle a bit with dos-ui.c, rename it to tui.c (text-based ui), add 1329: new file svgancui.c (ncurses ui) and try to make these two understand 1330: each other. 1331: 960829 New transdisk from Stefan Ropke (can write images) 1332: Apply Patrick Hanevolds BeBox patches. 1333: 96082x many changes to Exec. Still not booting (DMACON seems not to be set up 1334: properly, and sometimes Signal is called with task==0). 1335: 960821 Solaris sound from Manfred Thole. 1336: 960820 In filesys.c, get_fileinfo(), return volume name for top-level 1337: directory. 1338: 960819 Reimplement WritePixel(). Layer locking is still missing. 1339: 960818 Reverse meaning of -x flag for X11. More Exec code. 1340: Several changes to the main CPU loop and the way call traps work. 1341: 960817 Implement some simple Exec functions (Lists, AllocMem & friends) 1342: 960816 filesys.c fixes from David Varley. 1343: 960815 Implement graphics library region functions. 1344: 960814 Modify memory layout: All memory is linear now; get_real_address() 1345: returns a (UBYTE *). 1346: 960810 Add Gustavo's latest DOS code. 1347: In configure, include <sys/param.h> earlier for the sake of some *BSD. 1348: Add three options for sound code (bits, frequency, buffer size). 1349: Make -S option take a parameter; remove SPEED_UP_SIDMON_MODULES. 1350: New version of transrom (return 0, duh). 1351: 960805 Fixed the blitter line mode emulation (this time, really! I hope.) 1352: Thanks to Fabio Ciucci for a detailed description of the correct 1353: behaviour. 1354: 960730 Spent the last three days trying to make the filesystem emulation 1355: bootable by adding an expansion device for it. A fair bit of trial and 1356: error, but now it works! Even the hardfile now works with Kick 1.3, but 1357: you have to mount it manually after booting. 1358: hardfile.c, filesys.c, expansion.c and autoconf.c now are an 1359: entangled mess which badly needs to be cleaned up. 1360: We can now mount more than one filesystem even with Kick 1.3: we 1361: recognize them by param 2 of the startup packet, which has the same 1362: value as the dn_Startup field of the devicenode. 1363: Make Kickstart replacement work again (didn't like the CPU emulator 1364: changes) 1365: Include preliminary serial support from Stefan Reinauer. 1366: 960728 Fixed the scancodes for <> and #' keys in svga.c 1367: Apparently, CIA timer latches ought to be 0xFFFF after a reset 1368: (prevents Eagleplayer from crashing occasionally). #ifdeffed out a 1.1.1.2 root 1369: slightly weird call to INTREQ from RethinkICRB() 1.1 root 1370: 960727 Sound code rewritten again. Now uses events (five new ones). All 1371: modules seem to play correctly now. It's a bit slower, though. 1372: AF sound should work again, patches from Marcus Sundberg. 1373: 960723 ... and more CPU emulation bugs fixed by Herman. 1374: Added uae.library from Tauno Taipaleenmaki, plus support files in the 1375: "amiga" directory. 1376: Added some files for the XFree86/OS2 port from Krister Bergman. 1377: Reorganized all the directories. 1378: 960717 Add latest patch from Herman. 1379: More FAST_BLITTER options: 4 and 5. These finish the blit immediately. 1380: 960713 Call XAutoRepeatXXX() only if we know we want to change the state. 1381: 960709 Work around a few AIX bugs (ughhh... what a broken OS). New test for 1382: sys/select.h. 1383: In xui.c, don't try to communicate with a dead process. 1384: 960704 More bugfixes from Herman. 1385: Get rid of dummy_xlate(), use default_xlate() to abort with error. 1386: In svga.c, set correct_aspect to 0 if using lores. 1387: Change the Bcc exception 3 handling code a bit. 1388: Add new program "cpuopti" that takes gcc-generated assembly files and 1389: optimizes away unnecessary pushl/popl instructions on the x86. 1390: 960701 68020 exception handling & various bugfixes from Herman ten Brugge. 1391: In ersatz.c, use 0xFF0D instead of 0xF00D as trap opcode. 1392: Do MMU "emulation" (no-op MMU instructions, probably many cases decoded 1393: incorrectly). 1394: 960627 New file LIESMICH, with minimal German instructions. Somebody want to 1395: translate the docs to French, Spanish, Italian, all the Scandinavian 1396: languages, Hebrew, Polish, Dutch, Russian, Welsh, Gaelic and something 1397: [email protected] understands? (No offense meant - I'm sure there are 1398: brillant minds using AOL. There must be.) 1399: 960626 In zfile.c, make sure we delete the temporary file even if file 1400: decompression fails. 1401: Reimplemented sound support, this time following the HRM closely. Seems 1402: to work fine most of the time, but occasionally loses drum beats in 1403: TFMX modules. do_sound() is now unconditional, it calls 1404: flush_sound_buffer(), which is system-dependent. This breaks everything 1405: except Linux sound for now :( 1406: Add Herman ten Brugge's 68020/68881 emulation code. 1407: FreeBSD chokes if sys/mount.h is included without sys/types.h. Fix the 1408: configure script. 1409: 960622 More work on AGA code. 1410: Removed 2-bit display routines from custom.c. Ian: please use dithering 1411: code. 1412: Make slowmem and chipmem sizes run-time configurable. 1413: Mask out the high bits in BLT?PTH(). 1414: Add exception 3 checks to Bcc/BSR instructions. Seems to be not quite 1415: correct yet. 1416: Completely rewrote the disk emulation. We now create a big track buffer 1417: full of MFM data, used in a cyclic fashion by DSKBYTR() and friends. 1418: The current position in the buffer is determined by the cycle counter. 1419: DMA reads are now done in one piece. Two new event types: ev_diskblk 1420: and ev_diskindex. 1421: ARRGGHH! The RSI demo has _completely_ broken disk loading routines. 1422: They start disk DMA on a block while the blitter is still working on 1423: the same memory region. 1424: In zfile.c, unlink() the temporary file directly after opening it so 1425: it will be freed by the OS as soon as we close it (or crash... :) 1426: 960621 Merge pfield_sprite_h() and pfield_sprite_l() into one function. 1427: Split off new files blitter.c and blitter.h from custom.c. 1428: Fixed null-pointer dereference in zfile.c when filename has no 1429: extension. 1430: Add new field maxline to gfxvidinfo that prevents writing past the 1431: screen buffer if it has less lines than expected. 1432: Modify the 256 color allocation routine to set nb_cols to the same 1433: value first for r,g and b; allocate everything as usual and fill the 1434: lost colors afterwards with those that have the greatest difference. 1435: 960620 For some extremely weird reason, it is faster to simply call the 1436: assembly-optimized pfield_linetoscr_full routines _twice_ to double the 1437: line than calling the new (also assembly-optimized) 1438: pfield_linetoscr_full_double routines, at least when writing directly 1439: into the framebuffer. If someone has a good theory why, let me know 1440: about it. 1441: Drawing into memory is faster with the _double routines, but not 1442: noticeably (about 1%). 1443: Consequence: Removed the new pfield_linetoscr_full_double assembly 1444: routines again. 1445: Add a "--disable-gui" option to configure. 1446: Add Samuel Devulder's dithering code. Provide support for mono and 1447: 16 color X servers. 1448: Put an assembly version of DitherLine() in X86.S. 1449: New color mode (3) available, tells UAE to use 256 colors and dither 1450: the image. This is meant for people who have only a 256 color X server 1451: available, but it works with the SVGA version, too. It's much slower 1452: than normal 256 color mode, though. 1453: Use the color allocation algorithm from the dither code in 1454: alloc_colors256(), too. 1455: 960619 New files: zfile.c and zfile.h, from Samuel Devulder. These provide 1456: transparent decompression of various compressed file formats. Enabled 1457: by configure only for Unix systems. 1458: Eliminate dont_want_aspect. New option "-C", sets correct_aspect. Make 1459: video mode 3 640x480, video mode 4 800x600. Honor correct_aspect in 1460: 320x400, 640x480 and 800x600 mode with SVGAlib. 1461: Add fields maxlinetoscr and x_adjust to gfxvidinfo. 1462: Rename pfield_slow_linetoscr() to pfield_do_linetoscr(). Use new fields 1463: in gfxvidinfo to enable writing directly to the framebuffer in 1464: resolutions with <800 horizontal pixels. 1465: New function pfield_do_linetoscr_full(), called when sure that full 1466: line update is being done. 1467: Move some of the usage() information into some target_specific_usage() 1468: functions, defined in the various system-specific files. 1469: Support lower resolutions with LOW_BANDWIDTH, too. 1470: memcpy() within screen memory is dog slow. Prevent some common cases: 1471: 1. Use fill_line() to double a line in the border. 1472: 2. Add a parameter to pfield_do_linetoscr_full() to indicate whether 1473: the line has to be doubled. New functions 1474: pfield_linetoscr_*_double_slow() that simply do a memcpy(), plus 1475: optimized ones in X86.S that are much faster by avoiding the copy. 1476: Smart update code could get confused by lores modes when 1477: prev_max_diwstop changed from one frame to the next. New variable 1478: frame_redraw_necessary, which acts as a counter. It's initialized to 1479: 2 in interlace mode to handle that case properly, too. 1480: Move sprite priority checks into pfield_sprite_?(), move HAM 1481: calculations into new function decode_ham6() to simplify the various 1482: linetoscr functions. 1483: Fixed a bug that would cause sprites to get deformed in some cases 1484: when they overlapped (never seen it). 1485: 960618 New file: dos-snd.c, from Gustavo. 1486: 1487: 960617 Release 0.6.0 1488: 960617 Fix memory clobber in X86.S when diwfirstword==0. Eliminate double test 1489: for HAVE_SYS_MOUNT_H in sysdeps.h. 1490: 960616 Handle programs that don't wait for the blitter by finishing a pending 1491: blit as soon as a blitter register is written to (regardless of DMACON, 1492: to be safe). 1493: Call gui_led only if the LED changed. 1494: 960615 Fixed dual playfield sprite priorities. Optimized dual playfield code 1495: in X86.S. More work on AGA code. Get joystick status only in 1496: vsync_handler to speed things up. 1497: Make blitter fill more intelligent with table lookups instead of loop. 1498: 960614 DOS update from Gustavo. Pass real bitplane pointer to 1499: bpl_data_differs(), don't calculate it again. 1500: 960610 Fixed silly INTEL_FLAG_OPT bug: The new __asm__ expressions use 1501: regflags, which is of course _regflags on a.out... 1502: More BeBox fixes from Christian. 1503: Make the CIA bank bigger (A0..BF) and relax the CIA A/B selection 1504: checks to make broken software (Kingsoft's Emerald Mine, reportedly) 1505: happy. 1506: Default framerate is now 1. 1507: 960603 New BeBox code from Christian. Fix test for ELF in configure.in. 1508: 960529 genblitter.c: generate blitfunc as a function taking ULONGs and 1509: returning an ULONG. This makes custom.o about 4500 bytes smaller on the 1510: x86 by removing worthless size prefixes, and should increase 1511: performance (better for the cache, and the P6 reportedly doesn't like 1512: 16 bit instructions anyway). 1513: memory.c: Load Kickstart in one block and swap bytes after that if 1514: necessary (eliminates the need for the special bebox load routine) 1515: custom.c: Some preliminary work for AGA support. 1516: 960528 Saw a real awful piece of code that detects the right mouse button by 1517: reading a value from POT0DAT, counting up to 25, reading from POT0DAT 1518: again, and deciding the button is pressed if the value changed. Urgl! 1519: Added POT0DAT() in custom.c ... 1520: Gustavo's latest patches. 1521: 960525 Do index pulse handling in CIA_hsync_handler(). Make sure bit 12 in 1522: INTREQ gets set on an index pulse. Don't call DISK_Index() for now, 1523: since this breaks the Workbench. 1524: The CIA code should _probably_ not be resetting the bits in INTREQ. 1525: Disable this as an experiment, let's see what breaks. 1526: 960524 Z flag handling for ABCD/SBCD/ADDX/SUBX was wrong (must be clear if not 1527: zero, was set if zero). Some other flag bugs in these functions fixed. 1528: 960523 gfxlib.c update from Christian Schmitt. Some new Mac code from Ernesto, 1529: still not all of it, though. Italian keyboard from Alessandro Bissacco. 1530: 960522 Fix the CHK instruction. Implement middle mouse button. 1531: 960515 Fix some Nextstep problems in configure.in. 1532: 960513 New Makefile target "streifenfrei" to remove all output from configure. 1533: Use autoconf 2.7; 2.9 is buggy. 1534: 960512 Remove BIG_ALIGNMENT hack. Remove superfluous pfield_fetchdata() call 1535: in pfield_doline_slow_l() that resulted in garbage on the screen. 1536: Move blttbl array from custom.h to genblitter.c 1537: Use new lookup tables imm8_table and areg_byteinc in CPU emulation 1538: instead of ?: expressions. 1539: GCC appears to generate better code if the opcode is passed as ULONG to 1540: the CPU emulation functions instead of as UWORD. 1541: Modify some of the flag emulation __asm__ statements so that GCC uses 1542: less registers for them. 1543: 960510 Cast malloc() results to char *, for C++ compilers. 1544: 960509 Use test for GCC and __i386__ in options.h to decide whether to use 1545: intel flag optimization. 1546: Use test for wish4.0 to decide whether to use the GUI. 1547: 960507 New bebox.cpp from Christian. AF sound patches from Marcus Sundberg. 1548: 960505 Fix the configuration stuff so it works. Fix some bugs in gfxlib.c 1549: 960504 Use GNU autoconf scripts to generate Makefile and sysconfig.h. Add new 1550: files sysdeps.h that includes the right system header files. Remove 1551: amiga.h and Makefile. 1552: 960502 More Next code from Ian (new Uae.app directory, 2 bit drawing for 1553: custom.c). 1554: 960501 Allow the sound driver to set the frequency to a value that is slightly 1555: different from the requested one. 1556: 960430 Added AmigaOS port from Olaf Barthel. 1557: 960427 Fixed single playfield sprite priorities in X86.S. 1558: 960426 Added new NeXTwin.m from Ian. 1559: Turn off the blitter delay in line mode. 1560: Added a CPU optimization from Olivier Raoul: gencpu now reads a file 1561: "insncount" that can be generated by UAE during execution and generates 1562: specific functions for the most common opcodes. Not documented yet. 1563: 960414 Reimplemented the fast disk emulation in a more sane way. Also it's 1564: only done for reads now. (Plus, it no longer works :-/ Need to work 1565: some more on this). 1566: In blitter emulation, defer not only the setting of the bltfinish bit, 1567: but actually defer the whole blit for the number of cycles it will 1568: take. This makes programs the clear the screen while it is still being 1569: displayed look much better. 1570: Changed supervisor mode handling around a bit (was messy). 1571: New DOS code from Gustavo. 1572: 960412 Removed smart update method 2. Added Alessandro Bissacco's blitter 1573: optimization patch. 1574: Fixed some sprite problems: during hysnc, clear sprpos and sprctl, and 1575: don't do_sprites() in line 0. 1576: 960409 Be a little more intelligent about when to call pfield_linetoscr() from 1577: pfield_doline_slow(). It's only necessary if a color register changed. 1578: If it can be deferred to the end of the line, use the the _full 1579: variants. 1580: Some CIA TOD fixes. 1581: Better transdisk, accepts first/last track parameters. 1582: 960405 New function memcmpy(), inline assembler for the i386. Compares two 1583: memory blocks and copies them at the same time. Used in 1584: bpl_data_differs. 1585: 960404 French keyboard from Tristan Cavelier. Parallel port emulation from 1586: Stefan Reinauer. 1587: Turn bpl?pt and r_bpl?pt into arrays, simplify some code using them. 1588: 960401 Some parts of Ernesto's new Mac sources. 1589: 960331 filesys.c: Close filedescriptors in free_key(). get_path() sometimes 1590: read uninitialized bytes. 1591: Minor cleanups all over the place. 1592: unchain_mnn() leaves sibling intact, but clobbers next. customreset() 1593: didn't care about that and crashed. 1594: Use the __asm__("intel_flag_lookup") magic not only for DOS. 1595: Support 320x300 for X (without LOW_BANDWIDTH). 1596: Add new function fast_memcmp(), defined as memcmp if __i386__ is 1597: undefined, otherwise a slightly optimized inline assembly function. 1598: 960329 Some bug fixes in gencpu.c 1599: 960328 Stupid programs write odd playfield modulos into the hw registers... 1600: Eek! Sometimes, linedescr[] was indexed with a negative value... Add a 1601: vpos >= minfirstline check to pfield_may_need_update(). I really need 1602: to rewrite this in Oberon... 1603: Don't turn off SHM when LOW_BANDWIDTH is selected. 1604: Keep the nextpos and linepos variables from pfield_doline_slow_?() as 1605: globals and initialize them in pfield_may_need_udpate(). 1606: Modified alloc_colors256() some more. 1607: Try to make sprite DMA follow the Amiga DMA slots more closely by 1608: adding a currhp parameter to do_sprites() and calling it at the end 1609: of a scanline or in pfield_may_need_update(). 1610: 960327 Added Gustavo's latest DOS code, as far as possible. Modified X86.S to 1611: use a macro SYM() to create symbol names either with underscore or 1612: without. 1613: Fixed some very silly SVGAlib lores bugs. Move screen 8 pixels up in 1614: low resolution. 1615: Use diwstop instead of diwstart to caclulate the DIW for 320x200 modes. 1616: Reset it not only in calcdiw(), but also in init_frame(). 1617: Speed up 256 color allocation a little bit. 1618: 960326 New function flush_block() in xwin.c and svga.c. Called from 1619: do_flush_line() and (new function) do_flush_screen(). Modify struct 1620: vidbuf_description, new member maxblocklines that records the maximum 1621: number of scanlines that do_flush_line() should collect before calling 1622: flush_block(). If it is zero, then flush_line() is used as before. 1623: This makes the special case stuff for SHM unnecessary, so it's removed. 1624: Fixed a stupid bug in events code: Put ev_hsync in front of ev_copper, 1625: so that do_copper gets called with hpos == 0 instead of hpos == 227 at 1626: the beginning of the line. 1627: New function init_frame() that sets up some variables, called from 1628: customreset() and vsync_handler(). 1629: Move smart update code to pfield_doline() from pfield_doline_h() and 1630: ..._l(). Clean up these two with a macro DO_ONE_PLANE, removing 1631: duplicate code. 1632: Implement big blits and ECS chip ids. New configuration options 1633: ECS_AGNUS and ECS_DENISE. 1634: Implement MOVEP. 1635: 960325 Before calling pfield_may_need_update(), make sure the value that was 1636: written to a register actually differs from the previous one. 1637: New expansion code from Stefan Reinauer. 1638: Modify struct mem_notify_node to contain a pointer to a valid bit 1639: instead of the valid bit itself, so that the playfield code has to 1640: check only one flag to decide whether to draw the line (SU method 2) 1641: 960324 The chip_flags approach has several problems. A flag may cover an area 1642: in memory that spans two scanlines, or several scanlines may use the 1643: same area in memory. 1644: Provide two other, different methods for the smart update: 1645: 1. Save all the bitplane data for each line and compare the chipmem 1646: with the saved data to decide whether an update is necessary. 1647: 2. Use a chain of memory_notify_node structs instead of a single bit 1648: for flags. Each scanline owns a set of these structs and chains them 1649: into the right place, and the chipmem_?put routines walk the chains 1650: and set the modified bit for each element. 1651: Unfortunately, both methods are slower than the old one. Especially the 1652: first one has some advantages though: it speeds up programs that clear 1653: the screen each update and write the same contents back, and it 1654: can speed up double-buffering programs at full framerate, since it does 1655: not have to check whether the bitplane pointers have changed. 1656: Remember the first and last drawn line for each frame, and pass them to 1657: flush_screen. Use this in xwin.c for SHM. Modify SHM logic: if smart 1658: update is selected, call XShmPutImage() from flush_line() instead of 1659: from flush_screen(). But gather blocks of consecutive lines to avoid 1660: calling XShmPutImage() too often. 1661: 960323 "Smart update" method, based very loosely on Alessandro Bissacco's 1662: work, implemented: 1663: Add an array chip_flags that records any change made to specific words 1664: in chip memory. 1665: Move all the hardware registers relevant to playfield display into a 1666: new structure bplinfo. Remember the contents of this structure in 1667: struct line_description for every line on the screen. Avoid redrawing 1668: in pfield_doline if the screen memory has not been modified for the 1669: line to be drawn and if the information from the last frame matches 1670: that in the current frame. 1671: 960322 Duplicate all functions responsible for drawing (pfield_doline, 1672: pfield_doline_slow, pfield_sprite, pfield_*word_*res) and append _h 1673: or _l (ah, the golden C++ days, when we had templates... which never 1674: worked). Modify the *_l functions to support drawing in low resolution 1675: (i.e. 320x200). Change the options -d and -H to support selecting color 1676: mode and resolution, thereby getting rid of some SVGALIB_* options. 1677: Get rid of the old pfield_*word_*res functions. 1678: Collect information about the minimum diwstart value during the 1679: previous frame and use that in case 320x200 was selected to fit the 1680: image on the screen. 1681: Get rid of HAVE_JOYSTICK (breaks the "-J" option) 1682: 960321 Give up in op_illg() if opcode is 0x4e7b and the exception handler for 1683: it is NULL. In that case, it's a 68020 Kickstart. 1684: 960319 New Next code from Ian. SunOS target was still screwed (two CFLAGS). 1685: Turn -x option into a "hair cursor" option. Support multiple mounts, 1686: but warn if more than one is seen (still does not work with Kick 1.3). 1687: Integrated Samuel Devulder's new LOW_BANDWIDTH patch. 1688: 960318 Integrated the start of Markus Gietzen's gfx library replacement. 1689: Changed the interface between custom.c and the graphics code. There has 1690: to be a buffer holding the data of all the lines on the screen. For 1691: linear SVGAlib modes, this is the video memory. Eliminated -x option, 1692: prepare_line(), DrawPixel() and the X_?BIT_SCREEN options, replace with 1693: 3 versions of pfield_linetoscr for different datatypes. Implement 1694: proper handling of the borders above and below the DIW in custom.c 1695: instead of in flush_screen(). 1696: Move common code (color allocation) from all the graphics files to new 1697: file gfxutil.c. 1698: Swedish keyboard from Per Olofsson. 1699: 1700: 960315 Release 0.5.0 1701: 960315 Newest DOS port from Gustavo. New sgi-gcc target. 1702: 960314 Add -lXext to osf target. Use "rb" for fopen() in main.c 1703: 960310 Play a bit with the __asm__ constraints. Implement CHK. 1704: 960307 Fix some stupid Makefile errors. Call parse_cmdline() if no init file 1705: is found. 1706: First round of NextStep patches; new file NeXTwin.m 1707: Stupid bug in custom.c: The #define is called NO_FAST_DISK, not 1708: NO_FAST_FLOPPY. 1709: Fix one of the problems the Deform demo had with the blitter: The 1710: line texture wasn't rotated to the right position in blitter_init(). 1711: 960306 Use some black GCC __asm__ magic to calculate flags more quickly 1712: (config INTEL_FLAG_OPT) 1713: HAM was broken by pfield_linetoscr changes. Fixed. 1714: LOW_BANDWIDTH sometimes got confused when the display window changed. 1715: 960305 BCD instructions work well enough for Locomotive Basic on CPE. 1716: New function parse_cmdline_and_init_file() that reads ~/.uaerc or 1717: ./.uaerc and adds the options found in those files to those in argv[]. 1718: Patch from Denis Sablic to make disk image filenames runtime 1719: configurable. Extend it for the ROM filename. 1720: Remove some of the run-time configurable stuff from config.h. 1721: More X keysym fixes (I finally got a proper .Xmodmap ...) 1722: for SVGAlib: Delete key, and PgUp/PgDn as Amiga keys. 1723: The sound driver can now handle 22050 Hz and/or 8 bit samples. Both of 1724: these are the default with LINUX_SOUND_SLOW_MACHINE. 1725: Also use the SNDCTL_DSP_GETBLKSIZE ioctl and write the buffer when 1726: there is enough data. 1727: Abuse keybuf.c to provide a fake joystick emulation with the numeric 1728: pad (enable with -J) 1729: 960304 bebox.cpp from Christian. 1730: Rename pfield_linetoscr_full to pfield_linetoscr_full8. 1731: More x86 assembly: pfield_linetoscr_full16. 1732: 960303 SunOS target from Dirk Vangestel. Put some not-so-superfluous includes 1733: back in. Added the DOS specific patches to filesys.c. 1734: Started x86 assembly optimizations. New file X86.S, includes an 1735: optimized version of pfield_linetoscr (for 8 bit screens only). 1736: Don't use SA_RESTART if it isn't defined. 1737: prepare_line() wasn't called often enough (again...), leading to memory 1738: corruption and "hit the reset button" bugs when using SVGAlib. 1739: 960226 Get rid of bool, true and false in amiga.h and everywhere else. 1740: Copy yesterdays code to AF_SOUND code, too. 1741: Include first round of Christian Bauer's BeBox patches. Add AIX fix 1742: from Samuel Mackrill. 1743: Add #include <string.h> and #include <stdlib.h> in some more places. 1744: Modify gencpu.c and readcpu.c so that immediate types j and J (0..15 1745: and 1..8) can be merged. Replace HAVE_ONE_GIG... option with a new 1746: CPU_EMU_SIZE option that can be set to a value in the range 0..5, 1747: where 0 is minimum size and 5 is equivalent to HAVE_ONE_GIG... 1748: 960225 Remove multiplications in sound code, use a big lookup table. 1749: 960222 Go back to having only one memory bank table of type addrbank instead 1750: of several function pointer arrays. Eliminate the HAVE_BROKEN_SOFTWARE 1751: define by extending the memory bank table to 65536 entries. 1752: Remove remaining DUALCPU code. Allow BTST src,imm instructions in 1753: table68k. 1754: 960220 Back out filesys.c change from Stefan Reinauer: don't call V36 specific 1755: functions in expansion.library. 1756: Better fix for the filesys.c assign problems by Oliver Moehrke. 1757: Make new playfield code conditional on EXPERIMENTAL_SCREEN_UPDATE. 1758: Improve the 64bit variant of said code. Try to get alignment for 1759: apixels by putting it into a union with a long. 1760: Kill the child in gui_exit(). Make graphics_init() return a value and 1761: check it in main.c to see whether graphics were initialized. If not, 1762: call gui_exit() anyway. 1763: Use new 256 color allocation routine from svga.c in xwin.c, too. 1764: Make LOW_BANDWIDTH compile _and_ work (wow...). 1765: 960219 Fix bug in memory.c: When loading 256K Kickstart, copy 256K, not 128K. 1766: 960218 Finished the rest of the UI: reset, debug and quit buttons as well as 1767: drive LEDs. New target linux-gui; all others use dummy file nogui.c 1768: for now. 1769: 960217 The GUI now supports inserting and ejecting diskfiles and displays 1770: their names. Two pipes are used now, one for reading and one for 1771: writing. Properly wait for the process to start up. 1772: Use sigaction() instead of signal() in debug.c. 1773: More fixes for the new display routines: Need to do a final call to 1774: pfield_*word_*res with the data shifted right from the last fetched 1775: word. 1776: 960216 Copper & sprite bugfixes from Marco Nelissen. Better X keyboard support 1777: from Bruno Coste. 1778: Move my_strdup() from filesys.c to options.h 1779: New files xui.c, uae-ui (shell script) and uae-ui.tk (wish script). 1780: These create a GUI for the X version of the emulator. So far, the 1781: power LED works. 1782: 960215 Don't rely on SVGAlib headers defining any keycodes at all. 1783: Include Thorsten Frueauf's NetBSD patch. Apparently, the devname 1784: variable in hardfile.c caused a namespace collision, so rename it to 1785: uaedevname. Fastmem fixes, debugger help, and ConfigDev allocation in 1786: hardfile and filesys from Stefan Reinauer. 1787: xwin.c: Give the window a title. 1788: Half-implemented the DIVU.L, DIVS.L, MULU.L and MULS.L instructions. 1789: 960213 AF sound system support from Marcus Sundberg. Win95 keyboard support 1790: for SVGAlib from Thierry Lescot. Added most of Gustavo Goedert's MS-DOS 1791: port. 1792: When using the old pfield_*word_*res functions, the gen_pfield_tables() 1793: function was undefined. 1794: Hmmm, /dev/brain must have been unmounted when I wrote the new pfield_* 1795: functions. Now they make sure they access the apixels array only with 1796: addresses that are multiples of 16 bytes. 1797: 960212 Fix copy&paste bug in cia.c found by Marco Nelissen: Need to call 1798: RethinkICRB() instead of RethinkICRA() for CIA B timers. 1799: Added Stefan Reinauers autoconfig area/fastmem support. Added run-time 1800: options for use_slow_mem and use_fast_mem. 1801: Oops, the pfield_*word_*res() optimizations break completely on HPs and 1802: Sparcs. Now use this optimization only if we are using GCC 2.7. 1803: HPUX fixes in the Makefile. New target hpux-gcc. 1804: The code for clearing the areas above and below the DIW was trying to 1805: be a little too clever selecting the color. Just use the current 1806: background color. 1807: Added channel attachment to the sound code. Untested. 1808: 960211 Found some flag setting bugs in the rotate/shift instructions and in 1809: addx/subx (which I thought I had already fixed) by reimplementing 1810: DUALCPU mode to work with Ed's e68k. 1811: Argh! The copper is completely disabled during DDF in Hires 4 bitplane 1812: mode - so copper positions 0x30 and 0x34 are about 640 pixels apart. 1813: The Kickstart uses FF39FFFE to wait for the end of line 256 instead of 1814: FFDFFFFE as in all the other modes. This is implemented now, but 1815: probably not 100% correct. 1816: Added check whether SVGAlib doesn't support our mode. 1817: If using GCC >= 2.7, define __attribute__((aligned(16))) as 1818: BIG_ALIGNMENT in config.h. Use it for the apixels array to prevent 1819: potential problems on the Alpha. 1820: Tried to make the color selection routine produce better results in 256 1821: color mode. 1822: 960210 readdisk didn't work at all for large files - fixed. 1823: In pfield_doline(), clear the apixels array if playfield DMA is off. 1824: In SPRxCTL(), reset sprite mode when sprpos==sprctl==0 1825: Rewrite pfield_orword_hires() and friends to use lookup tables. No 1826: noticeable improvement on my machine, but might be different on other 1827: machines. Two versions of this code: one using 64bit longs on the Alpha. 1828: New targets linux-debug and linux-prof. 1829: Use 1MB slow mem. 1830: -funroll-loops is a little excessive. Remove it. 1831: Add support for linear addressing modes for SVGAlib version. Speedup 1832: is 20-30% on my old 486 VLB. Now, would someone please fix SVGAlib to 1833: support that for the S3-864 as well? 1834: Set SVGAlib keyboard mode to DONT_CATCH_CTRLC. 1835: Change custom.c, xwin.c and svga.c to keep track of the display window 1836: and background color and to clear the areas above and below the display 1837: window if necessary to remove garbage images from previous frames. 1838: Set the LOF bit in the Kickstart replacement init routine. Also 1839: initialize CIAs to Kick 1.3-like values. 1840: 960209 Some more -DHAVE_xxx_H options in the Makefile and filesys.c. DEC Alpha 1841: fixes for filesys.c from Ed and Marcus. HPUX fixes. 1842: New field in table68k for CPU type, parsed by readcpu and compared to 1843: CPU_LEVEL which is defined in config.h. New instructions MOVE2C, MOVEC2 1844: and CAS. Also a new field for priviledge level that is used by gencpu to 1845: generate tests for regs.s and Exception(8) calls if necessary. 1846: Move parsing of table68k into a new file build68k.c. Generate a file 1847: called cpudefs.c containing the information from table68k in 1848: machine-readable form. Change readcpu.c to use the array found in 1849: cpudefs.c. 1850: Don't generate the d8(An,Dn) addressing mode in-line. Generate a call to 1851: get_disp_ea(), which is an inline function in newcpu.h if UAE is 1852: configured for 68000 emulation; for 68020 emulation, it is defined in 1853: newcpu.c. 1854: Debugger could crash on illegals because there was no mnemonic defined 1855: in lookuptab[]. 1856: Return zero for SERDATR. 1857: 960207 It seems that the copper stops completely if an attempt to write to a 1858: specific register fails because of COPDANG. Apparently, the Kickstarts 1859: use this to stop the copper with a 0x00000000 longword. This leaves the 1860: question why they don't do 0xFFFFFFFE like everybody else. 1861: Enable 512K slow memory by default. 1862: Integrate Stefan Reinauers battclock patch that makes it work with 1863: newer Kickstarts. 1864: In cia.c, do the little index pulse hack even if dskdmaen==1, because 1865: DMA is only enabled when dskdmaen==2 (Helps the "Mad Decision" demo). 1866: Add solaris entry to Makefile (GCC, Openwin, -DHAVE_STATFS_H) 1867: Define HAVE_STRINGS_H for SGIs, change filesys.c accordingly. 1868: 960206 Build a smaller table instead of cputbl.c. Use readcpu and the smaller 1869: table to build the cpufunctbl array at run-time. 1870: Nuked the other half of the old CPU emulator. Reimplemented debugger to 1871: use the information generated by readcpu. 1872: Define HAVE_STATFS_H for SGIs in the Makefile, and use that as a test 1873: in filesys.c instead of #ifndef __linux. 1874: Hack filesys.c, get_path() to support the assign command. 1875: Add -fstrength-reduce and -funroll-loops in Makefile to make people 1876: nervous. 1877: Rewrite Sam Devulder's LOW_BANDWIDTH patch and add it to xwin.c. 1878: 960205 Forgot some PC-relative bit instructions in table68k. 1879: Nuked half of the old CPU emulator. 1880: Split gencpu.c into two parts, new one is called readcpu.c and just 1881: parses the table68k file. Link it to the main program. 1882: 1883: 960205 Release 0.4 1884: 960203 filesys.c, action_read(): Slightly more efficient code (translate Amiga 1885: address to real pointer). 1886: Moved some common code in the generate_* functions in gencpu.c to a 1887: separate function. 1888: 960202 Added an experimental fast disk option. Currently turned off by 1889: default (it's not such a big win). 1890: Attached sprite fixes (overlapping att. sprites looked bad, Katakis). 1891: Add sleep(1) before resetting the console to text mode when using 1892: SVGAlib: this might fix some screen corruption problems. 1893: Add sprite/playfield priority checking to the most important case 1894: (single playfield, no HAM). 1895: In filesys.c, do_find(): open() returns -1 on error, not zero. 1896: Return ERROR_OBJECT_WRONG_TYPE if do_find() is called for a directory 1897: (fixes Champions of Krynn harddisk installation). 1898: 960201 Don't abort if sound driver not present, just set produce_sound to 0. 1899: New files keybuf.c and keybuf.h to record keypresses in the right 1900: order and without losing any. In cia.c, force 15 scanlines between 1901: keypresses, just to be sure. 1902: unixfs.device _does_ work with Kick 1.3: just don't trust what Kick 1.3 1903: sends in the startup packet. For now, disable more than one mount per 1904: command line. 1905: Started integrating Ernesto's new Mac sources. 1906: Remove superfluous includes from some files. 1907: 960131 Added Ed's unixfs.device (great stuff). 1908: Adding ULONGs to pointers is a bad idea on the Alpha if the ULONG value 1909: really is signed. Add some casts to LONG in (pc_p + src) expressions 1910: in genpu.c. 1911: If DMACON is written and copper DMA is enabled, do a COPJMP1 at once. 1912: Helps the "Interference" demo. 1913: 960129 More SGI fixes from Ed. Bugfixes and transdisk improvements from Marcus 1914: Sundberg. 1915: Remove EXTRA_DEFINES from Makefile. Breaks some systems. 1916: Move common sprite code from pfield_doline() and pfield_doline_slow() 1917: to new function pfield_sprite(). The same sprite may appear more than 1918: once on the same line, so don't shift out the bits of sprdata[] and 1919: sprdatb[] while displaying it (Turrican I). 1920: In xwin.c and svga.c, barf if LINUX_SVGALIB doesn't match the file 1921: being compiled. 1922: Make all .o files depend on config.h in the Makefile. 1923: No need to exit if sound driver unavailable, but -S given. 1924: Small debugger fix: Missing space in output. 1925: Fix for the sprite logic: Specifically, use a state variable indicating 1926: whether the sprite has been restarted after a VSYNC. Fixes most 1927: Turrican problems. 1928: 960124 Added Denis Sablic's patch for sound run-time option. 1929: Added Ed Hanway's patch for better Makefile, X mouse cursor blanking 1930: and more SGI compilation fixes. 1931: 960123 Include options.h everywhere. 1932: Handle 8 bit GrayScale visuals like PseudoColor. 1933: Remove C++ leftovers from joystick code. 1934: 960122 When using the joystick driver, the button test must come after 1935: handle_events() in vsync_handler(). 1936: 960118 Removed all the remaining C++ comments. Changed all inline keywords to 1937: __inline__. Define __inline__ if not using gcc. 1938: Make proper prototypes for everything. Compile with maximum warnings + 1939: -ansi + -pedantic. 1940: Remove CIA_cycle(), obsolete. 1941: Reimplemented the STOP optimization in newcpu.c. Removed DualCPU 1942: support in CPU emulator. 1943: Real nasty bug in pfield_doline() fixed: sprxpos could be evaluated as 1944: negative, with not-so-amusing results. (Need to rewrite this in 1945: Oberon to get array bounds checking :-) 1946: 960117 Heroic effort: Rewrote the thing in C. This might help fix some 1947: problems with users being unable to compile it. 1948: Fixed a problem in hsync_handler(): Only call flush_line() for lines 1949: in the display window, i.e. when we did a prepare_line() before. 1950: Better code for relative branches: Don't use setpc(getpc()+x) calls, 1951: increment regs.pc_p instead. 1952: 960116 Reimplemented the function to load the Kickstart ROM. Use stdio instead 1953: of fstreams since this apparently does not work on the Mac. Detect 256K 1954: Kickstarts. Detect corrupt ROM images (calculate checksum). 1955: Added Ernesto Corvi's Mac port. Changed it around a bit, so it 1956: probably won't compile. 1957: 960115 Reinstate config.h options for X screen depth, so that DrawPixel() can 1958: be inlined in custom.cc for speed. xlinebuffer is now incremented in 1959: each call to DrawPixel() (for both X and SVGAlib) to get rid of some 1960: address calculations. 1961: 960114 Fixed X generic pixel drawing routine for SHM. 1962: Still trying to fix the harddisk emulation. 1963: uae.device no longer breaks the debugger (can step through uae.device 1964: functions now) 1965: Bugs affecting performance: SPCFLAG_STOP never got reset, and DSKLEN() 1966: would set SPCFLAG_DISK even if DMA was being turned off. 1967: Made slow memory a run-time option. 1968: Defer interrupts by one CPU instruction to give programs a chance to 1969: read INTREQR ("Seeing is Believing" and "Substance" demos) 1970: Added ScrollLock hack for X, too. 1971: 960113 SVGAlib version compiles again. Fixed SVGAlib mouse bug. 1972: Fixed SHM bug: Maximum scanline is 313, not 312. 1973: Sometimes, disk.cc missed a side change and would read the wrong data. 1974: Fixed. Apparently, this was the worst compatibility problem. 1975: Implemented trace mode. 1976: 960112 Changed layout of class amigamemory a little so that gcc can generate 1977: better addressing modes. 1978: Finally wrote functions in gencpu to generate MOVEMs. 1979: 960109 Integrated Ed Hanway's patches for better X support and run-time 1980: configuration of some options. 1981: Got rid of the direct VGA memory access. (Need to do this differently). 1982: Changed the method of drawing lines: custom.cc now tells the graphics 1983: code the line number and whether it needs to be doubleed before drawing 1984: it. 1985: Added Andre Beck's MIT-SHM patch. 1986: Remove warnings for newcpu.cc. 1987: 960108 Fixed exceptions in op_illg(): Need to decrement PC. 1988: 960107 Added an "uae.device" resident module at 0xF00000. This emulates a hard 1989: disk (fixed size 8MB for now). 1990: 960106 Moved some common code from pfield_doline() and pfield_doline_slow() to 1991: a separate function. This fixes a potential HAM bug (two static vars 1992: for the same value). 1993: Sound support for Linux. Works only with graphics off and the CPU 1994: slowed down. 1995: Better SVGAlib keyboard support. 1996: 960105 Added AvailMem(), AllocMem(), AllocAbs() and FreeMem() dummies. 1997: The Hardwired demo times the multiplication instructions and prints 1998: "This demo don't like Axel" if they are too fast. Apparently, Axel has 1999: a 68040. Added a WANT_SLOW_MULTIPLY option to config.h. 2000: Fixed the fast blitter emulation (seems to work now). 2001: 960104 Fixed all the ChangeLog entries from 95 that said 96 (oops??!) 2002: pfield_may_need_update() should check whether bitplane DMA is on. 2003: Added ersatz.cc and ersatz.h. The purpose of these files is to 2004: implement one or two Kickstart functions that are commonly called from 2005: bootblocks. This should help support some games and demos that only use 2006: the Kickstart as an initial track loader. So far, it's only good enough 2007: for one program. 2008: 951223 More intelligent event handling in the CPU emulator. Slightly faster. 2009: 951222 Optimize CPU emulation by inlining cctrue(). Also, the real PC no 2010: longer needs to be incremented each instruction. The real PC value 2011: now has to be fetched by m68k_getpc(). 2012: Added direct screen access for SVGAlib, but it didn't help much. I'll 2013: probably remove it again. 2014: The gencpu executable is 2M smaller if it allocates memory 2015: dynamically. 2016: 951216 custom_bput() enhanced a little. Now remembers the value that was 2017: written in the other half of the register. 2018: Apparently, the USEx bits of BLTCON0 are ignored in line draw mode. 2019: (Silents-Demo) 2020: 2021: 951212 Release 0.3 2022: 951212 Included Alessandro's battclock patch. 2023: Fixed mouse autocalibration for wrong-aspect screens. 2024: 951210 Joystick support for Linux. 2025: Better color matching for 256 color modes. 2026: Rewrote most of the memory management in plain C, mainly to avoid the 2027: various template bugs in some compilers, but also because gcc can't 2028: handle the regparm attribute for virtual functions yet. 2029: 951209 Added Alessandro's patches for automatic mouse calibration. 2030: Tried to optimize the blitter loop a bit. Doesn't work. 2031: 951205 Added Hannu's patches for diskfile write support. 2032: 951201 More portability fixes, especially for weird compilers that workstation 2033: vendors ship. 2034: 951125 More keys for X, some keyboard support for SVGAlib (slightly 2035: dangerous); beginnings of US keyboard support. 2036: 951124 256 color mode support for SVGAlib. FAST! 2037: 951123 Tiny tweak to central loops in playfield code results in much better 2038: assembly. Apparently, GCC does not feel too good about optimizing 2039: reference variables. 2040: 951113 Bug fix in the events code (nextevent must not be changed while events 2041: are being processed). 2042: 951112 The playfield can now be drawn with the right aspect (i.e., every line 2043: twice). Slower, but looks nicer and supports interlaced mode 2044: (flickerfree!). The first 29 lines (blanking interval) are omitted 2045: now to fit everything in 800x600. 2046: Oops, disk drive identification did not work. Fixed, all four drives 2047: appear now. 2048: Oops, CIA_reset() was there all the time but never got called. 2049: Optimized the planar->chunky conversion in pfield_doline() a little. 2050: This really is time critical. 2051: 951111 If colors change on a line, we might still be able to use the full 2052: line update, if the change occurred outside the DIW. Have to be a 2053: little careful, though. 2054: Playfield code now uses real pointers again, but makes sure it can 2055: read enough bytes to complete the current line without segfaulting. 2056: Oops, my "better estimate" (see below) was a mistake. Restored the 2057: original 4 hw cycles per instruction relation. This slows down the 2058: emulator while booting (more screen refreshs), but speeds up many 2059: demos that otherwise spend most of their time waiting for a specific 2060: raster position. 2061: Playfield modulos must be added immediately when DDF stops. (WOC demo) 2062: Portability fixes in disk.cc (null pointers). 2063: Implemented average frame rate calculation ('c' in the debugger). 2064: Debugger fixes. 2065: Sprite fixes (height was wrong, wrong priorities in fast update) 2066: Added an AutoConfig expansion RAM device. The OS seems to recognize 2067: it, but breaks sometime later (seems to be the same bug that kills 2068: the emulator when there's RAM at 0xC00000). 2069: SVGAlib now has mouse support, too. 2070: HAM mode implemented. 2071: 951110 Implemented fast complete line playfield update. Switches back if 2072: necessary. Fixed attached sprites bug. 2073: Copper wait no longer slows down the CPU emulation. (there were 2074: lots of new copper bugs because of this, but I hope I fixed all 2075: of them). 2076: Changed cia?t? from UWORD to ULONG, since there were overflows in 2077: the assertion (because of 65535+1 == 0). 2078: 951108 The DIVS remainder could have the wrong sign. 2079: New HAVE_BROKEN_SOFTWARE define in config.h that makes the emulator 2080: mask out the high byte of all addresses. 2081: Wrote genblitter.cc and replaced the awful code in blitter_blit() 2082: and blitter_line() with calls to the generated function. 2083: 951107 Implemented ?BCD. These don't really work yet. 2084: 2085: 951106 Release 0.2 2086: 951105 Fixed a bug in the new CIA timer code. 2087: Fixed flag settings for some cases of ADDX/SUBX 2088: 951104 Changed the main loop a bit - call all the *cycle() functions only if 2089: it is really necessary. I hope everything still works - at least it is 2090: twice as fast now :-D 2091: Improved mouse emulation - avoid overflows, permit "wraparound". 2092: Added debugger 'g' command. 2093: Removed some useless casts from the CPU emulator. 2094: Added a configuration option to prevent checks for odd addresses. Only 2095: very bad programs need this check. 2096: 951103 The sprite emulation sometimes did not work too well, especially with 2097: dual playfield mode. Hopefully fixed. 2098: 951102 The 10 cycle counter is more like a 5 cycle counter in this 2099: implementation. (Fine, that makes floppy loading even faster :-) 2100: Implemented mouse movement. Totally out of sync with the X pointer, 2101: but at least something. 2102: Found out about the XAutoRepeatOff() function. Real useful. 2103: DualCPU mode works again. 2104: Corrected flag settings for CMPA.W. 2105: Fixed DIV instructions: Don't change dest in case of overflow. 2106: 951031 The PC is now converted to a real pointer. This is safe (much safer 2107: than converting bitplane pointers, since the PC always has to be valid) 2108: and should speed things up a little. 2109: 951029 Some primitive event handling: 2 mouse buttons and 1 joystick button 2110: are emulated, as well as parts of the keyboard (only german mapping). 2111: Fixes: Delay values and sprite widths are always LoRes. Playfield 2 2112: uses colors 9..15. 2113: Implemented a frame rate configuration option that can speed up the 2114: emulation quite a bit. 2115: 951028 A-ha. The 68000 has one strange feature after all. MOVEM.W to Dn sign 2116: extends the value to a longword. 2117: Katakis expects that accessing odd addresses causes exception 3, so 2118: we have to emulate this. *Sigh* 2119: Do at least something with the index pulse bit. It's more or less a 2120: toggle now. 2121: Implemented sprites & dual playfields, both with small glitches. 2122: 951027 When LOF is set, the frame is one line longer. 2123: 951026 Implemented a preliminary diskfile type for special formats. Turrican 2124: boots up correctly (crashes if I want to play a game, though). 2125: Implemented EHB and added a few missing masking operations in the color 2126: handling. 2127: Fixed the absw addressing mode - need to sign extend here as well. 2128: 951025 Fixed another extremely stupid bug, this time in the playfield code. 2129: Each pixel was calculated four times... 2130: Increased the size of the apixels array - this was being overrun. 2131: 951024 Fixed an extremely stupid bug in flag settings for byte and word 2132: operations. 2133: The "sectors until gap" field must be in the range 1..11 instead of 2134: 0..10, or very bad things will happen if it is used to calculate a 2135: blit size. 2136: 951021 Don't use real pointers to fetch bitplane data - too many segfaults. 2137: Delay the copper after executing an instruction, or wait sequences like 2138: FFDF FFFE 0200 FFFE won't work. 2139: Some programs expect that the CPU is completely turned off if the 2140: blitter nasty bit is set. So be it. 2141: The RSI Megademo chokes when disk DMA fetches two syncs. Leave one out. 2142: The LOF bit wasn't set correctly. 2143: 951020 Blitter fixes: Load fill carry from FCI each line; keep the masked 2144: value of bltadat in bltolda 2145: Give the CPU twice as many "cycles" - this still is not even remotely 2146: correct, but a better estimate. 2147: 951017 Added SVGAlib support. Unfortunately, my graphics card isn't fully 2148: supported by the current SVGAlib version. 2149: 951015 More small optimizations to memory.h and custom.cc. 2150: Added code for 256 color screens. The type of screen has to be 2151: selected at compile time. 2152: 951014 Modified the memory management to be (hopefully) a little more 2153: efficient. 2154: Changed gencpu.cc to generate functions and a big function pointer 2155: array instead of the old case labels. The generated C++ files now 2156: compile a lot faster, and the code should be better as well. 2157: 951013 Implemented pseudo POTGOR to keep the RMB from being detected as 2158: pressed all the time. 2159: GenerateDecTab() generated TRAP incorrectly. 2160: Made some more instructions (MOVE.B A0,D0 etc) illegal in gencpu.cc. 2161: Fixed X colors. Fixed data fetching for HiRes screens. 2162: 951011 EXT.WL instructions set the flags. 2163: Implemented second CPU emulator, plus "DualCPU" option. The new CPU 2164: emulator is generated automatically from a file called table68k by 2165: a program called gencpu. 2166: 951002 Removed version information from the file headers. 2167: Removed some sillinesses in custom.cc. 2168: DSKLEN bug fixed (mask out 0xC000). 2169: Playfield code rewritten. Now supports horizontal scrolling. Implemented 2170: some primitive color support. 2171: 950927 Fixed predecrement/postincrement addressing with byte size for the 2172: stack pointer. 2173: 950926 Fixes to the disk code: Terminate disk DMA, flip disk side, read more 2174: than just two sectors during disk DMA, fix checksum calculation. 2175: Fixed copper comparison bugs. 2176: 2177: 950901 Release 0.1 2178: 950826 bugfix in GenerateDecTab(): LEA.W instructions were generated. 2179: 950312 New file disk.cc, for (guess what) disk support. Doesn't work yet. 2180: 950311 Multiplication instructions were generating 16 bit results. 2181: Sign extension was wrong in some places. 2182: Removed bugs in the blitter (one word width: ALWM & AFWM and line mode) 2183: The Kickstart logo looks perfect now. 2184: Playfield routine should check BPLCON0 instead of BLTCON0 2185: 950309 ASR D8,D0 is not a valid instruction. 2186: Bitplane pointers were not incremented. 2187: Copper comparison didn't work. COP2LC and bitplane pointers were written 2188: incorrectly. Fixed. 2189: Something that bears a striking resemblance to the familiar Kickstart 2190: logo now appears in my X window! 2191: 950306 ROR used to set the X flag. Bug fixes in GenerateDecTab. 2192: More bug fixes in several 68000 instructions. 2193: Improved blitter. ?????? KS1.3 doesn't seem to set BLTDMOD on a 2194: line draw. What is this?? 2195: Fixed stupid bugs in playfield code. 2196: 950305 fixed bugs in opcode generation and interrupt handling. Implemented 2197: STOP. Fixed flag settings: Result wasn't masked. Ooops!! 2198: ADDQ #imm,An doesn't set flags. 2199: One-shot timer mode didn't work. 2200: Implemented blitter, doesn't work. 2201: Some primitive and slow playfield support, only to make the things that 2202: hopefully will soon appear visible. 2203: 950304 CIA timers ought to work OK. Copper is emulated. 2204: Emulator loops infinitely when trying to initialize the console.device 2205: 950303 experiments with X, figured out how to open a window and draw pixels. 2206: No graphics emulation yet, though. 2207: 950301 Nearly all instructions work. 2208: Fixed supervisor mode stack. 2209: The memory manager now handles CIA chips. 2210: 950228 Bug fixes in 68000 code, exceptions and more instructions implemented 2211: Memory management extended to handle custom chips as well. 2212: Debugger improved. 2213: Kickstart passes memory & CPU type test, builds up some system 2214: structures. 2215: 950227 MC68000 & little debugger for tracing. It can execute the first couple 2216: of KS1.3 instructions, but doesn't get past the memory test. 2217: 950225 Work begun
