Arrange to 220: generate code for all CPU emulator variants and to select them at 221: run-time. 222: Get rid of copper cheat mode, re-use "-C" option for CPU selection. 223: 980312 In COPxLCL, mask out LSB (Axel Wefers). 224: newcpu.h: Always compile in both get_disp_ea versions with a different 225: name. Delete USE_POINTER option; always use pointer. Don't fill 226: prefetch in m68k_setpc, do it in callers where necessary. Compile in 227: two versions of get_ixxxx, with different names for prefetch and 228: non-prefetch. Change gencpu.c to use these appropriately. 229: Don't generate 16 small CPU emulation source files. With a decent 230: machine it's no problem to compile all the code in one file. Also turn 231: off -O3 for gcc, -O2 does fine since all the necessary __inline__s are 232: there, and the compiler takes less memory that way. 233: Don't include <linux/joystick.h>, duplicate some definitions from 234: there instead. Makes configure.in simpler, too. 235: Fix Makefile.in/configure.in and a couple of other places to support 236: building in a separate directory (sort of; not complete yet). 237: Remove p2c.[ch] and genp2c when doing make clean. 238: Delete code to support Tcl/Tk and XForms GUIs. 239: 971215 More Amiga and BeOS patches from Sam and Christian. 240: 971205 Move some more code from custom.c to audio.c.

Set FLOPPY_SPEED to 4. 258: 971107 Make ggi.c compile again, fix a few bugs and add Picasso support. 259: 971106 Fill prefetch queue after executing an encrypted ROM illegal insn. 260: 971105 Initialize the sprites during customreset now that init_hardware_frame 261: no longer does it. 262: 971104 Implement action_set_file_size as required by the specs. 263: SetPanning/picasso96_state: XOffset and YOffset are signed. 264: 971103 xwin.c: Offer 640x512 and 320x256 resolutions in windowed Picasso mode. 265: Add a few more memory banks in memory.c (A3000 stuff - nonfunctional) 266: Don't map kickmem at address 0 if using replacement Kickstart. 267: Must fill prefetch buffer when calling calltraps or ersatz functions. 268: Write out hardfile parameters in write_filesys_config(). 269: xwin.c: Support 15 bit displays. 270: 971101 Add latest patches by Samuel Devulder. Improve hardfile support in 271: tui.c. 272: 971031 Offer "-U" only ifdef PICASSO96. 273: Add support for mounting multiple hardfiles in any order. 274: Don't reset sprite state in init_hardware_frame. Instead, allow SPRxPT 275: functions to set the state to SPR_restart in the vertical blanking 276: area. 277: 971030 Fix 8MB Chip RAM. 278: filesys_dev_storeinfo: New function and calltrap. Use it to store 279: per-unit data (which now includes geometry information) in the 280: parampacket. Modify filesys.asm to use it instead of trying to find 281: the values by itself. 282: 971028 "AMIROMTYPE1" has 11 characters, not 0. 283: 971027 Implement encrypted ROM features. Comment out non-working InvertRect 284: optimization. 285: 971026 Fix some problems in PlanarToDirect and CopyColorIndexMappingA2U. 286: 971022 Remove fixed paths in genp2c.c (oops...) 287: Some more XF86VidMode hacks. 288: Include target.h in sysdeps.h. Define PICASSO96_SUPPORTED for X11, 289: SVGAlib and Win32. Don't compile in Picasso support if this macro isn't 290: defined. 291: 971021 xwin.c: Picasso code wants to use bit_unit, not bitdepth. Also correct 292: byteorder (it's B8G8R8A8 from the Amiga's point of view). 293: Fix Picasso InvertRect function. 294: Half-hearted attempt at 24 bit support in the X11 version, with some 295: awful code in custom.c. 296: Make the X11/VidMode version try to resize the screen for Picasso mode 297: switches. 298: 971020 Delete option -5, make -4 take an argument. Disable z3fastmem and 299: Picasso emulation when using a 24 bit address space. 300: 971019 record_color_change: No need to remember a color table if the current 301: line hasn't been decided yet. 302: Add XF86VidMode extension support. 303: Integrate Stefan's Zorro III support, add support for up to 64MB fast. 304: xwin.c: Refresh the whole Picasso screen if there are Expose events. 305: Fix module length calculation for *Tracker modules. 306: Use a 32 bit address space by default if CPU_LEVEL > 1. New option -5. 307: 971018 Apparently it's not possible to turn on bitplane DMA in the middle of 308: the line, so call post_decide_line only when the number of planes is 309: modified, not in DMACON. 310: genp2c.c: New file, generates planar to chunky conversion routines. 311: Remove those which are now generated from custom.c. 312: 971017 Make row_map an array, not a pointer to one. 313: Audio periods may not be 0, so initialize them to 65535 in customreset. 314: Implement "S" command in the debugger.

Update od-win32 with latest code. 322: Remove fast_memcmp routine. 323: Include penguin.h before xwin.h everywhere. Declare a few semaphores 324: for multithreaded setups in xwin.h. Move inhibit_frame stuff to xwin.h. 325: 971011 gencpu.c: Don't generate labels without following statement. Don't 326: directly generate assembly statements if X86_ASSEMBLY, instead generate 327: code that uses macros defined in machdep/m68k.h. 328: 971008 xwin.c, svga.c, custom.c, uaelib.c: Add picasso96 code. Add Picasso 329: selection to configure. 330: Move common variables (mouse stuff, gfxvidinfo, xcolors) from graphics 331: files to custom.c. 332: memory.c: custom chip area isn't supposed to be mapped at 0x200000. Use 333: dummy bank for now. 334: od-linux/joystick.c: Open different devices for different joysticks. 335: From Win32 sources: set vsyncmintime in m68k_go. 336: 971005 genblitter.c: blitzero is initialized to 1, not to 0, so we need to 337: clear, not set it. 338: 970928 Add another user interface for X11 using libgtk+. 339: 970925 audio.c: For stereo sound, double all lookup table values. 340: Added (preliminary) win32.c. 341: 970923 DISK_check_change: Should call gui_filename when ejecting. 342: 970922 Fix od-linux/joystick.c compilation problem with recent kernels. 343: Merge results of the UAE meeting: 344: New serial code (Stefan Reinauer) 345: Expansion "test card" support (Stefan Reinauer) 346: New GGI code (Christian Schmitt), also configure/Makefile changes 347: to make it compile. 348: Fix 68020/FPU code. 349: Call do_mousehack before every read of the mouse position to get more 350: accurate values. 351: Add sd-file directory; add support for it in configure. 352: Add stereo support in audio.c, od-linux/sound.[ch], and main.c. 353: Fix copper problem: call decide_line in calc_copcomp_true; and if the 354: copper wouldn't wait normally (position reached), but the hardware is 355: fetching data in Hires 4 plane mode, delay until ddf stop. 356: t-ascii.h: Asciiart target understands "-x" parameter. 357: 970823 gencpu.c [X86_ASSEMBLY]: Turn input constraints for scratch into output 358: constraints. 359: 970626 Fix 24 bit address space logic (Mathias Ortmann). 360: Raise exception 3 for Bcc.L insns if CPU_LEVEL < 1. Reported by Stefan 361: Ropke. 362: Remove USER_PROGRAMS_BEHAVE for normal emulator. Remove hacks to 363: generate expanded CPU functions for specific opcodes. Replace with code 364: that reads an instruction count file and sorts gencpu output by 365: frequency of the called opcodes. 366: 970625 Calltraps (at least those with call_m68k calls in them) were broken by 367: the CPU emulator changes. Now use Axxx opcodes as calltraps. 368: Include pOS port by Samuel Devulder. 369: 970624 Solaris sound patches by Manfred Thole. 370: gencpu.c: The generated code shouldn't just check for odd addresses, 371: it should also call Exception... 372: 970622 gencpu.c: don't emit return statements; make code jump to a function 373: end label instead. Make genamode() check for odd addresses, also reduce 374: code duplication. Interpret getv parameter so that data is fetched if 375: getv == 1, and the address is checked if getv != 0.

Fix a number of prefetch bugs in gencpu.c. 387: newcpu.h: m68k_incpc(), get_i{byte,word,long}: New function/macros. 388: Also add oldpc parameter to m68k_do_[bj]sr(). gencpu.c: use all this. 389: CPU functions now don't use nextiword; they keep the PC constant and 390: increment it with the right value at the end. 391: If chipmem_size > 2MB, disable fastmem. 392: In configure.in and od-linux/joystick.c, use ljoystick.h as name for 393: the replacement file for a broken <linux/joystick.h> 394: configure.in: Check for post-gcc-2.7.2 option "-mno-schedule-prologue" 395: and use it for compiling the optimized CPU files if it exists. 396: 970618 Rename hardfile.device to uaehf.device to avoid name clashes. Suggested 397: by George Nicolaidis. 398: Reimplement CPU prefetch by making gencpu aware of it so it generates 399: code that fetches data from the right places automatically. Also reduce 400: prefetch length to 4 bytes. 401: 970612 memory.h: Include osdep/memory.h. missing.c: implement xmalloc(). 402: Throughout: use xmalloc instead of malloc. 403: Apply changes by Sam Devulder. 404: 970608 Fix ncurses.c so that it links. Fix configure so that it can be enabled 405: Get rid of spixstate by implementing a new sprite drawing method. 406: 970607 do_copper_cheat(): New function, Implement inaccurate, line-based 407: copper as an option (-C). calc_copcomp_true(): Fix possible hr 4 plane 408: bug (split the wait into several pieces in this mode). 409: Allow 0 bytes for fast and bogomem (to override .uaerc) 410: 970606 Fix some bugs in transdisk, and make it compile with SAS C (Joanne Dow) 411: Stupid compilation fixes: Get rid of "==" in shell scripts, check that 412: B300 and friends are defined in serial.c before using them. 413: Implement blitter prefetch. Fix silly typo in main.c that prevented 414: immediate blits. 415: init_ham_decoding(): new function, handles case where the first few 416: pixels of a HAM display are outside the window. 417: 970605 disk.c: Get rid of need_read. Save cylinder/track number for the data 418: in the MFM buffer for each drive. Force rereads on disk insert and 419: write operations. In drive_fill_bigbuf(), do nothing if saved data 420: matches current. Fix disk change logic: give the program time to read 421: the change bit a couple of times before inserting a new disk. 422: custom.c: Fix really subtle bug: when deciding a line as border, 423: plfstrt/plflinelen were not set up properly, which could confuse 424: post_decide_line(), and eventually there would be lines decided as 425: playfield with plfstrt == 0, plflinelen == -32 ==> Bang. A related 426: bug was that setting DDFSTRT to 0 would result in both plfstrt and 427: plfstop having value 0. 428: gfxutil.c: Fix bug that could cause color values to go out of bounds. 429: xwin.c, svga.c: When dithering, color values were not doubled properly. 430: 970604 filesys.c: when deleting an a_ino, remove it from hash table (Mathias 431: Ortmann). In do_find(), if creating a file failed and we didn't have 432: an a_ino before, call delete_aino on the one we created. 433: More configure changes: Add $X_PRE_LIBS and $X_EXTRA_LIBS in some 434: places. See if MIT-SHM support for X will compile and link. Always 435: compile it in if it will. Turn DONT_WANT_SHM and LOW_BANDWIDTH into 436: run-time options (-T, -L). Use single line buffer when dithering and 437: in low-bandwidth mode (but in all cases there's a full buffer for the 438: X image). 439: memory.c: Don't map in custom regs at 0x200000 if chipmem_size > 2MB. 440: Split up init_sound(): new function setup_sound(). Make "-B" accept 441: minimum and maximum values as in Gustavo's latest patch. Add code to 442: tui.c to support changing buffer size, number of bits and frequency. 443: 970603 If using compiler, define NO_EXCEPTION_3 and NO_PREFETCH_BUFFER. 444: (bugreport by Raphael Poss). 445: GGI support from Christian Schmitt/Stefan Reinauer. More serial patches 446: from Stefan. 3 button joystick patch from Mathias. 447: Add linemem field to gfxvidinfo, for systems that don't want to keep 448: a buffer of the full screen. Adjust custom.c to use it instead of 449: bufmem if it's not NULL (mostly by Mathias). svga.c, xwin.c: Use single 450: line buffer in some cases. xwin.c: If USE_DGA_EXTENSION, undef 451: LOW_BANDWIDTH. Move test of DONT_WANT_SHM after inclusion of config.h 452: Make configure.in a bit more structured. 453: Move colormodes array to main.c. 454: 970602 gfxlib.c: Start implementing layers workalike. 455: md-i386-gcc/support.c: Don't mix sleep and alarm. (Petter Schau) 456: 970601 Remove may_run_compiled. Print error and abort if m68k_go is called 457: twice. 458: Fix yesterdays bugfix in svga.c. 459: Change FRAME_RATE_HACK so it tries to average the times a bit. 460: Re-implement a call_m68k function in autoconf.c. The new version 461: works by doing some heavy setjmp/longjmp magic and switching stacks. 462: With this, it's even possible to call things that Wait(), so use 463: the new functionality in gfxlib.c to call LockLayer() in WritePixel(). 464: 970531 Turn some inline functions in memory.h into macros. Get rid of 465: get_along and get_aword. Implement CIA A OVL bit. 466: main.c: Add missing close_sound() call. 467: Remove INTEL_FLAG_OPT, use X86_ASSEMBLY for everything. 468: tui.c/svgancui.c: Implement scrollable menus. Add code to select 469: video mode from a given list. Add "graphics_setup" call to graphics 470: specific files. Use it in svga.c to build a video mode menu. 471: Fix bug in svga.c that would crash non-linear modes. 472: disk.c needs to include gensound.h and sounddep/sound.h. 473: Fix bug in fuzzy_memset. In pfield_init_linetoscr, always adjust ddf 474: values if lores hack is being used. 475: 970530 Apply some patches by Samuel Devulder. 476: 970529 filesys.c: In "Houston, we have a problem" case, do not only delete 477: the oldest ExKey, but also use it instead of random memory for the 478: new one. Attempt to reduce the number of lost exkeys by allocating 479: them in action_examine_next instead of action_examine_object. 480: Initialize the "uniq" field of unit->rootnode. 481: Attempt to speed up sprite drawing loop. 482: Implement sprite<->sprite collisions. 483: Get rid of -Wtraditional. 484: 970524 New config option NO_PREFETCH_BUFFER. Emulate 16 byte prefetch if 485: unset. 486: For exception 3, the stack frame seems to be: 487: (saved SR).w, (faulting address).l, (faulting instruction).w, 0.w, 488: (pc at fault time).l. Make everything that could generate this fault 489: handle it properly. That got Cybernoid II working! 490: 970523 Makefile.in: Make sure $(DEBUGFLAGS) is used for CPU emulation files. 491: memory.c: Don't map chipmem at 0x200000, use custom chip bank for now. 492: 970507 configure.in: Mutate ac_cv_c_inline=no to ac_cv_c_inline= 493: Check for tcgetattr, <sys/termios.h>, cfmakeraw, <sys/ioctl.h> 494: Check for sem_init in -lposix4 (Marc Zimmermann) 495: serial.c, cia.c, cia.h, serial.c: changes (Stefan Reinauer) 496: Make disk gap 360 (Michael Krause) 497: 970404 In configure, check for features.h before including it in test program. 498: 970401 New option -4. Bugreport by Mirko Viviani. 499: 970324 Petter Schau says the exception frame for Bus Error and Address Error 500: is 14 bytes, not 6, on the 68000. Change Exception() accordingly. 501: It's *** OUCH *** day! Make hardfile beginio return the correct value. 502: Also load execbase before calling ReplyMsg(). 503: It's *** OUCH *** day again! The filesystem asm code was an odd number 504: of bytes, leaving the hardfile code unaligned. 505: 970318 custom.c: Rename spron to sprst, and use new variable spron to indicate 506: for which sprites the sprite pointer registers have been written. Don't 507: do sprite DMA if spron==0. (The problem was that some programs write 508: SPRxCTL and then SPRxPT, which used to set the sprite state to 509: SPR_restart, but it must be SPR_waiting_start.) 510: Turn a few m68k_reset()s into uae_reset()s. 511: New variable nr_joysticks. Delete joystickpresent. New arg "nr" for 512: getjoystate() and read_joystick(). 513: New extra keycode AK_RCTRL. Handle multiple joysticks & different key 514: replacements in keybuf.c/custom.c. Make tui.c handle all the settings. 515: 970310 od-linux/joystick.c now compiles again without the joystick header. 516: Fix some problems in configure; also check whether [n]curses.h defines 517: attr_t. Keep count of warnings and errors during configuration and 518: print a hopefully helpful message at the end. 519: disk.c sanitized by Mathias Ortmann. 520: Change the replacement getopt around a bit. 521: execlib.c, timerdev.c: Files removed. This will never be compatible 522: enough. Also remove related code (several SPCFLAGs, etc.) 523: Make main.c a bit nicer by introducing additional defines for the t-* 524: files. Also canonicalize the .uaerc file on all systems, eliminating 525: lines starting with '#' in the process. 526: Remove code in autoconf.c to set up 8MB chip; move it to filesys.asm. 527: Try doing the copper end-of-line hack in copper_memory_cycles(). 528: Disable the copper speedup hack. 529: 970309 Add a small, dumb hash table to struct _unit to speed up repeated 530: aino lookups. Delete aino in action_delete_object(). Move children in 531: action_rename_object(). In action_examine_next(), call new function 532: lookup_child_aino_for_exnext() which behaves more or less like 533: lookup_child_aino(), except it uses new function get_aname() to 534: translate filenames. 535: More portability fixes. New links set up in configure: sounddep, 536: target.h. All machine-dependent and joystick code removed 537: from os.c, renamed to audio.c. os.h renamed to audio.h, joystick stuff 538: moved to joystick.h. New directory targets/. 539: missing.c: New file. 540: 970308 Rewrite filesystem. Now it keeps one unique "a_inode" structure for 541: every object in the filesystem. This contains Amiga name, native 542: name, Amiga permissions, lock counts and several links for building 543: a tree structure. Keys are now made only for files which need a fd 544: and a file position. 545: Treat invalid locking modes als shared. 546: Comment out the code using readdir_r because that function appears 547: to be broken in glibc-2.0.1. 548: Clear RES2 in all packets before handling them. 549: Give mousehack the same task priority as the input.device. 550: Fix (?) some silly bugs in disk.c. 551: 970307 Include some Acorn port code from Peter Teichmann. 552: Yet Another Serial Diff from Stefan. 553: 970306 filesys.c: Don't just crash if lookup_key() has no success. 554: action_find_write() is supposed to create the file if it does not 555: exist. 556: 970305 More DOS patches. Make the Makefile parallel-make safe. 557: svgancui.c: Do cyclic search if character is typed in file selector. 558: my_alphasort(): New function (work around glibc bug) 559: custom.c: Fix error in yesterdays change. 560: filesys.h: New file. 561: 970304 New serial patch from Stefan and Christian. 562: Remove the assembler code to generate inputevents. Instead, add a new 563: Amiga C program ("mousehack") which does the trick. New function 564: mousehack_helper() in custom.c, activated by calltrap 0xF0FF70. 565: Mouse default is now always normal_mouse, not follow_mouse. 566: Do disk change checks only every 1/2 second. disk.c: Reverse 567: nodskchange to dskchange, and make sure there has been a step with the 568: drive empty before calling drive_insert() from DISK_check_change() (but 569: this _still_ doesn't work. Arrrghh). 570: 970303 filesys.c: Initialize _all_ of struct _unit in startup_handler(). 571: Remove message_lock and friends and use new variables cmds_sent, 572: cmds_acked and cmds_completed to determine when to send dummy messages. 573: Changed examinekey handling so that "dir all" on a large tree doesn't 574: crash anymore (it used to reuse the top-level exkeys which were still 575: in use after a wraparound). Don't allocate examinekeys if we're 576: examining files. 577: Check for readdir_r in configure. Use a wrapper my_readdir() around 578: either readdir or readdir_r. 579: Call filesys_reset() also from filesys_diagentry(). 580: Get rid of most of uaelib.c. Now there isn't a library, just a calltrap 581: at 0xF0FF60. Changed uae_pragmas.h accordingly and recompiled uaectrl. 582: Added a bunch of "volatile"s in various places in filesys.c and 583: penguin.h. 584: Make the filesystem reset-safe in the threaded case (paranoia changes). 585: Check disk changes only every 1/10 second in vsync_handler(). 586: Add assembler code to generate InputEvents once every vblank to 587: filesys.asm. (Doesn't work yet.) 588: 970302 filesys.c: Get rid of DosPacket type, pass pointers into Amiga memory 589: instead. Use GET_PCK_* and PUT_PCK_* macros to access fields. 590: Start making filesystem code thread safe & multithreaded. Move static 591: variables from some functions into struct _unit, likewise the key 592: and exkey variables. Add code to filesys.asm to queue commands which 593: did not complete and to reply to them later. Do multithreading if 594: compiled with SUPPORT_THREADS. See source for details. 595: Change hardfile and uaelib code not to call 68k routines. Make emulator 596: traps more efficient (no need to save regs, don't need SPCFLAG_EMULTRAP 597: anymore). 598: 970301 Fixed ncurses.c so it works with currprefs. 599: filesys_reset(): New function, called from customreset(). 600: Changed source layout. Break up machdep into machdep, osdep and 601: threaddep. 602: penguin.h: Now supports arbitrary types in pipes. 603: Changed filesys.c so that no 68k code is called from native C code. 604: filesys.asm, filesys.sh: New files. filesys.asm contains some 605: startup code and the main loop for the filesystem. Several locks 606: are allocated by the assembler code for use by the C code. 607: DOS_AllocMem(), DOS_FreeMem(), make_dev(), build_parmpacket(), 608: filesys_init(): Functions removed. 609: 970228 ncurses.c: Fix problem in b/w modes. 610: finish_drawing_frame(): Don't need to draw lines in multipenguin mode. 611: Move all options into new struct uae_prefs. New variables currprefs, 612: changed_prefs. 613: svgancui.c, tui_filereq(): If user presses a key, start search at 614: current position, not at the beginning. 615: DISK_check_change(): new function, compares currprefs with 616: changed_prefs and handles diskchanges if they differ. Called from 617: vsync_handler(). 618: DISK_validate_filename(): new function, checks whether a file exists. 619: Modify svga.c and tui.c so that F11 now brings up a limited UI. 620: 970227 Reimplement Mathias Ortmann's frame rate hack: New option HAVE_RDTSC 621: in config.h. New typedef frame_time_t. New variables vsynctime and 622: vsyncmintime. New function machdep_init() in md-*/support.c which 623: sets up vsynctime in the md-i386-gcc and md-i386-linux cases. Use 624: all of those in events.h, do_cycles() to determine whether to spend 625: more time on the CPU emulation. 626: Add missing "int i;" to xwin.c, init_colors(). 627: Unroll some loops in sample_*handler(). 628: Improve quitting/resetting behaviour: Move quit_program from GUI 629: specific files to main.c. New functions uae_reset() and uae_quit(), 630: quit_program is now handled in vsync_handler() and m68k_go(). 631: New variable sample_evtime, used in customreset() and set up in 632: init_sound(). 633: 970226 Solaris sound update from Manfred Thole. 634: keybuf.c: Decided that it doesn't need locking after all. 635: Add a bunch of Gustavo's latest diffs. (I hate CR characters!) 636: Move gfxvidinfo from all the target-specific files to custom.c 637: More Win32 stuff: New function notice_new_xcolors(). 638: 970225 configure.in: In shell string comparisons, always put spaces around = 639: Add warning about standard SVGAlib being incompatible with 640: LinuxThreads. 641: os.c, SOLARIS_SOUND: Remove reference to obsolete variable smplcnt. 642: Two new variables sound8_base and sound16_base. 643: sysdeps.h: Split off some stuff into md-amiga/amiga-kludges.h. Also 644: make the main types now uae_u32 and variants instead of ULONG, etc. 645: Convert some files to use the new types. 646: cia.c: use int/long instead of ULONG/UWORD/etc for most static vars. 647: xdebug.c: Some cleanup. 648: md-i386-linux/penguin.h: Fix bug. Add "chunks" parameter to 649: init_comm_pipe. Use it to decide in write routine whether to signal 650: the other thread if it's waiting. Add no_buffer parameter to 651: write_comm_pipe_int. 652: Start adding Mathias Ortmann's Win32 patches. 653: md-i386-win32: New directory 654: include/sysconfig.h.win32: New file 655: custom.c: is_lastline: new variable, set in hsync_handler(). 656: sysdeps.h: Make it possible for system specific code to say that 657: POSIX/ANSI stdio/malloc functions aren't present and are defined 658: by a system-specific file instead. In filesys.c, don't reference 659: errno if DONT_HAVE_POSIX is defined. 660: readcpu.h: Kludge around the fact that Messysoft C apparently doesn't 661: handle enums properly. 662: newcpu.c/sysdeps.h: Preprocessor magic for 64 bit constants to get 663: around a problem with MS C. 664: md-*/penguin.h: Add dummy definitions for semaphores. 665: keybuf.c: Use semaphores to synchronize access. 666: os.c, win32 sound stuff: add memcpy avoidance code. 667: 970221 X86.S: Don't use .type ifdef USE_UNDERSCORE. 668: Move thread support configuration to configure from config.h. Change 669: pipe implementation to use POSIX semaphore functions. 670: 970217 From Samuel Devulder: Fix off-by-one error in LINE_TO_SCR, EHB case. 671: 970215 customreset(): Initialize current_colors.color_regs to invalid values 672: [reported by Samuel Devulder]. config.h: Uncomment ECS_DENISE [reported 673: by Mathias Ortmann]. Add ami-win.c and custom.c patch from Samuel 674: Devulder. 675: 970213 disk.c: Set FLOPPY_SPEED to 3 676: custom.c: SPRxCTL_1(): if spron was SPR_restart set it to 677: SPR_waiting_start. do_sprites(): don't do that. 678: SPRxPT{H,L}: Call decide_line(). 679: 970210 custom.c, X86.S: Do LORES_HACK for dual playfield screens. Plug memory 680: leak in custom_reset(). Fix pfield_draw_line() not to do so many 681: multiplications. Make line_changed a char array. In remember_ctable(), 682: remember comparison results also if negative. 683: In 8 and 16 bit graphics modes, use the high parts of the color values 684: to duplicate the actual values. This saves a lot of code in the 685: hdoubling routines. Add a special fill_line in the X86_ASSEMBLY case. 686: Check for glibc-2 and libpthread in configure. 687: options.h: In fuzzy_memset(), do rounding slightly more conservative. 688: Add tons of new keycodes to svga.c 689: In record_color_change(), also check if vertically outside DIW. 690: New variable hdiwstate, to represent the horizontal DIW state machine 691: (thanks Petter!) Handled in reset_decisions(), finish_decisions() and 692: decide_diw(). 693: 970209 Change ncurses.c not to do so many multiplications/divisions. Add bold 694: character support. Add color support. Make configure recognize 695: --without-svgalib and enable ncurses.c in that case. 696: 970208 X86.S, custom.c: Do LORES_HACK for EHB screens also. 697: New function write_log(); convert some fprintf(stderr, ...) calls. 698: 970207 Argh, Linux/i386/ELF check in configure got broken by latest sh-utils. 699: In disk.c, drive_reset(), clear nodskchange flag. 700: 970206 Sprite fix from Mathias Ortmann: _really_ get rid of SPR_vtop, and 701: replace all uses by SPR_stop. 1.1.1.2 root 702: 970204 Disk change fix from Mathias Ortmann. 703: 970203 New file ncurses.c, from Samuel Devulder. 704: Disabled Exec stuff completely. Now it isn't even compiled in anymore. 705: 970129 Changes from Samuel Devulder for Amiga and Christian Bauer for BeBox. 706: 970122 Reorder the set_planes_unaligned functions so that better code is 707: generated. Remove the or_planes_unaligned functions, add a parameter 708: do_or to the set_planes functions and rely on the compiler to optimize 709: the additional if away. 710: post_decide_line() can now turn DMA off early. 711: Make struct flag_struct 64 bits large for i386 systems, so we can use 712: long move insns without clobbering the X flag. 713: "make clean" should delete machdep/support.o. 714: Maybe we do need SPR_vtop after all - undo 970120 change. Instead, 715: comment out the code that clears the pos and ctl words at vsync time. 716: In xwin.c, restrict window height to 300 or 600 depending on linedbl 717: mode. 718: 970121 Get rid of SPCFLAG_BLIT, call do_blitter() directly. 719: In finish_decisions(), don't check for sprite draws in the border. 720: Reimplement the SMART_UPDATE define so that the memcmpy() overhead can 721: be avoided by not setting it (but this usually loses). 722: Detect 7 lores planes in BPLCON0() and change to 6 to avoid memory 723: clobbers. 724: In pfield_draw_line(), do memcpy linedoubling after handling the line 725: to be doubled, not when we see a LINE_AS_PREVIOUS. Get rid of prev_ypos 726: parameter. 727: Add special code for bpldelay1 == bpldelay2 to the UNALIGNED_PROFITABLE 728: code. 729: In pfield_init_linetoscr(), when delays 1 and 2 differ, clear the areas 730: which are covered only by half of the planes at the start and end of 731: the DDF area. 732: Replace FASTER_CPU and LINUX_SOUND_SLOW_MACHINE with M68K_SPEED. 733: Replace fast_unaligned_memset macros with fuzzy_memset; use this also 734: in pfield_init_linetoscr(). 735: Use real (PAL) vblank end in do_sprites(). 736: 970120 Mask out high byte in DDF{STRT,STOP} 737: Oops, forgot about long frames while calculating the bounds of all the 738: maxvpos*2-sized arrays. Increment them all by two. 739: Try to detect empty sprites before recording them for the drawing code, 740: but be careful not to hurt attached sprites. 741: From Paul Kienitz: hack for keyboard code in cia.c to work better with 742: newer Kickstarts; small cleanup in cpuopti.c. 743: Undo yesterday's change in copper_memory_cycles(), instead call 744: decide_line() each iteration and test whether copper_cycle_time == -1 745: to determine whether we're vertically in the DIW. 746: calculate_copper_cycle_time() could get astronomical plane counts due 747: to missing masking operation. 748: No need to put the copper to sleep for one memory cycle after a WAIT, 749: merge that with the two cycles for the next instruction. 750: Get rid of SPR_vtop, no longer needed (it was unnatural anyway) 751: 970119 Implemented alternate pfield_doline functions that access the apixels 752: array at unaligned addresses; conditional on UNALIGNED_PROFITABLE. 753: Move LORES_HACK from config.h to custom.c. 754: Fix loop exit test for pfield_linetoscr_hdouble_asm8(). Clear the 755: right parts of apixels in pfield_init_linetoscr() when LORES_HACK is 756: enabled. 757: Get rid of bordercol array: the decision-making code should handle 758: lines in the border correctly by setting line_changed. 759: Disable bitplane DMA if more than 4 hires bitplanes are set in BPLCON0. 760: Fix some more copper timing inaccuracies: used to test 761: thisline_decision.which without calling decide_line() before. 762: 970118 Now remember BPLCON1 changes during data fetch. New functions 763: decide_delay(), pfield_adjust_delay(); new fields in struct drawinfo 764: and new variables next_delay_change, delay_changes. 765: Forgot to set copstate to COP_morewait in one case in do_copper(). 766: Add a kludge that checks for copper position 0xDC and changes it to 767: 0xDE. 768: Restore equality test for vertical sprite positions. Disable sprite 769: DMA before the end of the vertical blank area. 770: Mask not only the positions, but also comparison values in 771: calc_copcomp_true(). 772: 970117 Change custom_bput to put the byte value in each half of the word that 773: is put. 774: 970116 disk.c: Set the gap between sector 11 and 0 to 380 words. Andromeda's 775: "Seven Seas" demo expects at least 320. Make the KILLEHB bit 776: conditional on AGA_CHIPSET. Decide BPLCON1 (scrolling delays) in 777: decide_diw(). Fix off-by-one errors in the very_broken_program case 778: of decide_plane(). Fix aspect calculation when horizontal resolutions 779: differ. Simplify copper horizontal comparison logic slightly. 780: Fix divide by zero errors when reading from empty floppies. 781: 970115 pfield_draw_line(): Check for frame_redraw_necessary also for border 782: lines. New global variable pfield_last_drawn_line, used to implement 783: clever Y centering. Make the KILLEHB test conditional on ECS_AGNUS. 784: Move joystick and sound initialization before gui startup. Adapt tui.c 785: so it understands the gfx_requested_* options. 786: We can't always avoid clearing pixdata.apixels if DIW is larger than 787: DDF. There may be sprites in the area outside DDF, but inside the DIW, 788: so we can't just adjust linetoscr_diw_{start,end} blindly in 789: pfield_init_linetoscr() [Sanity Arte demo]. 790: 970114 Bebox diffs from Christian Bauer. 791: Support for Symmetric Multi Penguins under Linux (start second thread 792: with clone and use some pipes for communication - rather simpleminded 793: for now). Rework do_flush_line() and do_flush_screen() so that X 794: libraries are only called from the first thread. 795: Eliminate valid field from struct decision (set which to -2 instead of 796: valid = 0) 797: Fix definition for gui_filename() in xdebug.c to use const char * for 798: the second parameter. Remove CRs from disk.c (now how did they get in 799: there??). Likewise for cpuopti.c. 800: 970113 When post_decide_line() detects mid-line DDF change, must adjust 801: bitplane pointers in decide_plane() also. Make plfstrt the earlier a 802: position in this case, and adjust bitplane pointers/modulos 803: accordingly. 804: current_hpos() isn't what GCC calls a constant function. 805: Replace line_drawinfo[current_change_set] with new variable 806: curr_drawinfo throughout. Likewise for new variables prev_drawinfo, 807: {curr,prev}_{color_{change,table}s,sprite_positions}; all initialized 808: in init_drawing_frame (). Turn line_data into a 2dim. array, do some 809: CSE/SR on line_data[lineno] in pfield_doline_{l,h}() and 810: decide_plane(). Make some custom registers unsigned int instead of 811: UWORD. 812: calc_copcomp_true(): Masking with 0xF000 isn't likely to give 0xC0000. 813: Comment out bplcon{3,4} from struct decision. 814: 970112 filesys.c, action_set_protect(): if __unix is defined, check whether 815: user wants to change directory protection, and if so, force rwx to be 816: the new protection. 817: Force sane window sizes in xwin.c, and set width/height from mode specs 818: in svga.c. 819: Implement LORES_HACK compile-time option. 820: Whee, there _are_ broken programs that enable bitplane DMA in the 821: middle of the data fetch area, draw half a picture on the first line 822: and the full picture on all subsequent lines. New function 823: post_decide_line(), called from BPLCON0() and DMACON() which tries to 824: detect this case and turns the decision from border to playfield if 825: necessary. 826: New arrays, sprvstart and sprvstop, calculated in SPRxPOS and SPRxCTL, 827: and used by do_sprites. Handle sprites with vstart == vstop correctly. 828: Sprite vpos comparisons are now done with <= , not ==. 829: _Now_ the X86-specific linetoscr routines do their masking correctly. 830: configure: If we have GCC, #define GCCCONSTFUNC as __attribute__ 831: ((const)) 832: 970111 Eliminate can_draw from struct decision. 833: Change vertical DIW code; use enum of two states (waiting for start and 834: for stop) which is updated in decide_line(). Lines during the wait for 835: stop phase are decided as border. No data is fetched outside the 836: vertical DIW. 837: Optimize copper memory cycle calculation a little: the new variable 838: copper_cycle_time is set to a time >= 0 if this time is constant 839: (i.e. 2). Calculated whenever DMA, BPLCON0, or DIW state changes. 840: blitter.c, genblitter.c, custom.c: For BLTBDAT, follow the HRM which 841: says that immediate data is shifted as soon as it is written. This 842: seems to be wrong for the A channel, though. Also, don't change prevb 843: during blitter loops if DMA B is off (Sanity Arte). Turn FAST_BLITTER 844: stuff into run-time option "-n", and eliminate the ancient blitting 845: code (former FAST_BLITTER == 0). 846: Big OOPS: Copper move checked copcon, but there was no COPCON function 847: so it was always zero -> copper-controlled blitter never worked. As a 848: speed optimization, recognize 00010000 copper commands and put the 849: copper to sleep until the blit is finished. 850: Slow down the blitter in decide_line() if bitplane DMA steals blitter/ 851: copper/CPU cycles (but this code is commented out for now). 852: 970110 New function pfield_init_linetoscr(). Move calculation of diw_end and 853: diw_start values there from x86-specific code. Also use DDF values to 854: determine where data in pixdata.apixels is valid. The x86-specific 855: linetoscr routines now only do the alignment masking (and they now do 856: it correctly, too). 857: Got rid of the display-related contents of struct draw_info, make 858: static variables and them initialize from pfield_draw_line() only when 859: necessary in function pfield_expand_dp_bplcon (). Get rid of the four 860: saved_* arrays, remember line_drawinfo instead now that it's smaller. 861: Color compare avoidance didn't work because color_src_match didn't get 862: set when a compare was successful. Fixed. 863: Reorder parts of the decision-making code so that less redundant checks 864: are performed. 865: Add clever x centering. Change "-O" option parameter format. 866: In md-i386-linux/support.c, memcmpy(), do memcmp() first, then switch 867: to a plain memcpy routine once we find the first difference. 868: Patches from Stefan Reinauer/Christian Schmitt for 869: xdebug.c/configure.in 870: New uae-ui.tk from Volker Zota. 871: Add --enable-profiling to configure.in. 872: Check for period==0 in AUDxPER() was accidentally commented out - 873: revert. 874: 970109 Some tweaks in X86.S, plus a new option X86_PPRO_OPT to use movzbl 875: instead of xorl/movb when possible. 876: Fix maxline calculation in finish_drawing_frame(). 877: Make next_lineno always a valid array index. Decrease minfirstline to 878: 21 (NTSC vblank end). New option -O to specify display parameters, 879: supersedes -d and -C which will be removed eventually. Differentiate 880: between line doubling and aspect correction. Put aspect correction code 881: in custom.c. 882: Remove some more unused stuff from custom.c. 883: Fix Makefile problems when cpuopti isn't used. 884: 970108 use_lores isn't initialized before custom_init(), setup lores_frame and 885: friends in customreset(). Optimize spixstate clearing. Optimize border 886: drawing with copper color changes (use fill_line instead of linetoscr) 887: Fix the sprite DMA logic, it now works with the Interference demo. 888: Silly bug: Sprite 7 never got displayed (introduced sometime last week) 889: Implement USER_PROGRAMS_BEHAVE for normal (non-compiler) CPU emulation. 890: Add most of Gustavo's last patch (new dir md-i386-dos) 891: 970107 Finish rewriting most of the drawing code in custom.c/X86.S. See 892: README.PROGRAMMERS and source for details. Improvements include better 893: copper precision, better interlace support, hopefully much less bugs 894: and not too many new ones. 895: Remove calc_adjustment() and gfxvidinfo.x_adjust; replace with code in 896: custom.c that looks at gfxvidinfo.follow_diwstop (new field) 897: Some operations (like EHB playfields) now have a higher penalty than 898: before, the assumption being that these are rare and the normal case 899: runs faster if it doesn't have to care too much about exceptions. 900: Fix sign mismatch bug in BPL1MOD() and BPL2MOD(). 901: 970104 Move x_ShowEA() from xdebug.c in newcpu.c, rename as ShowEA(). 902: 970102 Add check for XK_W to decode_es() in xwin.c. 903: New uae-ui.tk from Volker Zota. 904: 961218 Add a patch by Bernie Solomon to overcome a problem with K&R compilers. 905: Change X86.S in a way that may make it either faster or slower. 906: Fix ADF_EXT1. 907: 961217 #ifdef XK_dead_*, since Solaris doesn't have it. 908: 961202 Fixed joystick.h problem in configure. X11/DGA support from Kai 909: Kollmorgen. 910: 961117 Some fixes in svgancui.c. 911: 961112 Gustavo's latest patch, with GUS support for DOS by Michael Sontheimer. 912: Add menu browsing to tui.c/svgancui.c 913: 961107 Fix m68k_areg and m68k_dreg macros (put args in parentheses) 914: Initialize gfxvidinfo.maxlinetoscr in xwin.c (found by Sam Devulder) 915: 961104 svgancui.c tui_refresh() routine tweaked to work with the non-standard 916: ncurses that came with my new SuSE-Linux CD. 917: 961031 Added Christian Schmitt's xdebug.c (disabled for this release) 918: 961024 Module search function from Michael Krause. 919: 961019 Add Samuel Devulder's Amiga patches. 920: 961018 Don't use -lm on NeXTStep. 921: 961017 configure checks for -lforms. 922: 961016 Ian Stephenson's new NeXTwin.m. Make CLXDAT return 0 (no collisions) 923: transdisk and transrom patches from Rodney Hester. Don't warn about 924: 256K Kickstarts. Check diskfile sizes and try to determine whether it's 925: a normal or a HD diskfile. No HD drive identification yet (is it 926: different?) 927: 961013 Corrected lots of bugs in the return address stack. Fix some errors in 928: the compiler memory management. Use the "locked" flag for hash entries 929: differently, and don't enforce it on a cache flush. Compile JMP to a 930: constant address. 931: 961012 Remove regs from cache before sign extending them for ADDA, MOVEA and 932: similar things. Compile NOPs to nothing. Implement variable shifts/ 933: rotates. Most shifts clear the V flag: Handle this in the compiler by 934: some extra magic sequences after shifts or in the CC_AFTER_RO case in 935: flush_cc_cache(). 936: Implement a stack containing return addresses and their hash entries, 937: and compile JSR (to constant addresses)/BSR/RTS instructions inline. 938: 961011 compiler.c: Several bugs introduced in the last two days fixed. 939: New function compile_note_modify() which is used when an ea is 940: modified. This replaces calls to storeea with eaino_s == eaino_d. 941: Bah, the 386 doesn't set flags on a NOT. Use CC_TEST_REG again. 942: Do flag life analysis until no more changes are found. 943: Make sure all "data" parts of EAs are locked exclusively (esp. for 944: LEA, PEA) 945: 961010 compiler.c: Finish yesterdays changes. Get rid of reg/offset 946: bookkeeping in m68k_compile_block(), keep the information in struct 947: ea_info instead. Rewrite all instructions to use the new fetch and 948: store routines. 949: Don't force a byteorder conversion in sync_reg() if the reg doesn't need 950: to be written back. Don't do a SAHF or equivalent in compile_condbranch 951: if we are doing a BRA or BF. 952: Don't use CC_TEST_REG for NEG and NOT (this was inefficient for NOT and 953: wrong for NEG). 954: 961009 compiler.c: Two types of locks for registers; shared and exclusive. 955: Implement better EA fetching and storing routines. For pdi addressing 956: modes, lock the necessary registers shared before calling prepareea. 957: Unlock those registers again in generate_possible_exit(). 958: 961008 MOVEM instructions in the compiler to an absolute address could have 959: caused random memory corruption. 960: 961007 Spanish keyboard support for X by Ruben Martinez. Some configure fixes 961: (don't assume current dir is in path, don't assume ncurses.h exists if 962: libncurses does). 963: If we're calling 68k code from an emulator function, don't use compiled 964: code. 965: Add a compilation option USER_PROGRAMS_BEHAVE (for compiler). Make 966: compiler hash table larger. 967: 961004 Fix typo in configure.in. 968: Modify the compiler so it doesn't ever throw away code, unless it's 969: necessary for a cache flush. 970: Didn't quite squash the compiler flag bug yesterday. Try again. 971: In filesys.c, do_find(), add a parameter fallback that indicates that 972: the open should be retried with O_RDONLY if it failed with O_RDWR. 973: Use this in find_input(). This fixes problems with r/o files on r/w 974: volumes. 975: 961003 Play around with the x86 specific memory access functions. Problem: 976: __attribute__((regparam)) isn't reliable, and it seems that that's a 977: rather hard to fix bug in GCC. Add some alternatives to 978: md-i386-linux/memory.h; these aren't used yet though. 979: Huh, the compiler was completely wrong about the flag needs of 980: conditional instructions. I wonder how it could work at all... 981: Remove a and d arrays from struct regstruct; replace with array regs 982: with 16 elements. This allows better code for get_disp_ea() 983: 961002 BeBox diffs from Christian Bauer. Move all code from main() to new 984: function real_main(). 985: 961001 Use do_get_mem_*() functions for nextiword(), nextilong() and new 986: function nextibyte(). 987: 960930 genblitter optimizations: Don't generate expressions in genblitter, use 988: a second program called gengenblitter to generate a table of 989: expressions for genblitter to use. gengenblitter knows about a lot of 990: rules to simplify expressions. Some other tweaks to make GCC output 991: better assembly for blitfunc.c. 992: 960927 Turn off LED() in xwin.c (may fix SunOS joystick emulation problems) 993: Call XFlush() and XSync() when exiting. 994: Add some DOS patches. 995: Add hooks in filesys.c to support filesystem units in a GUI. Use them 996: in tui.c. Bugfixes in svgancui.c. Change the way tui_refresh() works. 997: New option "-A". 998: 960925 For read-only filesystems (CD...), use O_RDONLY in action_find_input. 999: 960923 Save options file even if rename fails. 1000: Mirror address space every 16MB like we used to (got turned off by 1001: accident). 1002: Move some checks out of options.h into configure. Set up md-* 1003: directories with machine-dependent stuff in them; configure creates 1004: a link called machdep to the appropriate one. 1005: 960918 Solaris sound update from Manfred Thole. 1006: 960917 Add a timer.device replacement (buggy). 1007: 960916 Tristan Cavelier's french keyboard patch. 1008: Apply ReadTheSpecsBeforeYouWrite(tm) technology to AddPort(). 1009: Implement RemPort(), GetCC(). 1010: 960915 Tighten up some of the return values in Exec. 1011: 960914 EXEC: Implement RemTask(), ObtainSemaphoreList() and 1012: ReleaseSemaphoreList(). Set up more fields of the ExecBase properly 1013: and Enqueue it in the library list. Make InitResident call AddLibrary 1014: when appropriate (otherwise, intuition is never put into the library 1015: list). Fix major braino in Obtain/ReleaseSemaphore() (tried to Enqueue 1016: tasks into two lists). Make OpenLibrary() honor the version parameter. 1017: 960913 EXEC: Idle task now runs in user mode (abuse 0xFF0D as second STOP 1018: instruction). Make EXEC_IntTrap perform the RTE before trying to 1019: schedule. 1020: 960912 Solaris sound didn't compile. So much for making blind changes without 1021: being able to test them. 1022: 960911 As soon as you compile it under Solaris, it bombs... Now check that the 1023: hardfile exists before determining the size in main.c. 1024: execlib fixes: Set master DMA enable bit at startup, fix interrupt 1025: code to survive an interrupt that occurs before the proper SetIntVector 1026: call. Implement RawDoFmt(), CloseDevice(), CloseLibrary(), 1027: FindResident(). 1.1 root 1028: 960905 Lower 8 bits of POTGOR should be 0. 1029: 960904 Implement MULU, MULS, ADDX and SUBX in compiler. 1030: 960903 ncurses interface works. DOS people: please use the new portable tui.c 1031: and turn dos-ui.c into a frontend for conio.h, similar to svgancui.c 1032: In xui.c, unlink the temporary files ASAP. 1033: Two new command-line options, "-o" and "-G". 1034: Get rid of sz_unknown. 1035: compiler.h, compiler.c: New files. 1036: filesys.c, action_read(): Added a hack to test whether the first four 1037: bytes read from a file a file contain 0x000003F3 (HUNK_HEADER), in 1038: which case there's probably a LoadSeg() call going on and we ought to 1039: flush the cache. Also, use the fact that memory is now linear. 1040: 960902 Struggle a bit with dos-ui.c, rename it to tui.c (text-based ui), add 1041: new file svgancui.c (ncurses ui) and try to make these two understand 1042: each other. 1043: 960829 New transdisk from Stefan Ropke (can write images) 1044: Apply Patrick Hanevolds BeBox patches. 1045: 96082x many changes to Exec. Still not booting (DMACON seems not to be set up 1046: properly, and sometimes Signal is called with task==0). 1047: 960821 Solaris sound from Manfred Thole. 1048: 960820 In filesys.c, get_fileinfo(), return volume name for top-level 1049: directory. 1050: 960819 Reimplement WritePixel(). Layer locking is still missing. 1051: 960818 Reverse meaning of -x flag for X11. More Exec code. 1052: Several changes to the main CPU loop and the way call traps work. 1053: 960817 Implement some simple Exec functions (Lists, AllocMem & friends) 1054: 960816 filesys.c fixes from David Varley. 1055: 960815 Implement graphics library region functions. 1056: 960814 Modify memory layout: All memory is linear now; get_real_address() 1057: returns a (UBYTE *). 1058: 960810 Add Gustavo's latest DOS code. 1059: In configure, include <sys/param.h> earlier for the sake of some *BSD. 1060: Add three options for sound code (bits, frequency, buffer size). 1061: Make -S option take a parameter; remove SPEED_UP_SIDMON_MODULES. 1062: New version of transrom (return 0, duh). 1063: 960805 Fixed the blitter line mode emulation (this time, really! I hope.) 1064: Thanks to Fabio Ciucci for a detailed description of the correct 1065: behaviour. 1066: 960730 Spent the last three days trying to make the filesystem emulation 1067: bootable by adding an expansion device for it. A fair bit of trial and 1068: error, but now it works! Even the hardfile now works with Kick 1.3, but 1069: you have to mount it manually after booting. 1070: hardfile.c, filesys.c, expansion.c and autoconf.c now are an 1071: entangled mess which badly needs to be cleaned up. 1072: We can now mount more than one filesystem even with Kick 1.3: we 1073: recognize them by param 2 of the startup packet, which has the same 1074: value as the dn_Startup field of the devicenode. 1075: Make Kickstart replacement work again (didn't like the CPU emulator 1076: changes) 1077: Include preliminary serial support from Stefan Reinauer. 1078: 960728 Fixed the scancodes for <> and #' keys in svga.c 1079: Apparently, CIA timer latches ought to be 0xFFFF after a reset 1080: (prevents Eagleplayer from crashing occasionally). #ifdeffed out a 1.1.1.2 root 1081: slightly weird call to INTREQ from RethinkICRB() 1.1 root 1082: 960727 Sound code rewritten again. Now uses events (five new ones). All 1083: modules seem to play correctly now. It's a bit slower, though. 1084: AF sound should work again, patches from Marcus Sundberg. 1085: 960723 ... and more CPU emulation bugs fixed by Herman. 1086: Added uae.library from Tauno Taipaleenmaki, plus support files in the 1087: "amiga" directory. 1088: Added some files for the XFree86/OS2 port from Krister Bergman. 1089: Reorganized all the directories. 1090: 960717 Add latest patch from Herman. 1091: More FAST_BLITTER options: 4 and 5. These finish the blit immediately. 1092: 960713 Call XAutoRepeatXXX() only if we know we want to change the state. 1093: 960709 Work around a few AIX bugs (ughhh... what a broken OS). New test for 1094: sys/select.h. 1095: In xui.c, don't try to communicate with a dead process. 1096: 960704 More bugfixes from Herman. 1097: Get rid of dummy_xlate(), use default_xlate() to abort with error. 1098: In svga.c, set correct_aspect to 0 if using lores. 1099: Change the Bcc exception 3 handling code a bit. 1100: Add new program "cpuopti" that takes gcc-generated assembly files and 1101: optimizes away unnecessary pushl/popl instructions on the x86. 1102: 960701 68020 exception handling & various bugfixes from Herman ten Brugge. 1103: In ersatz.c, use 0xFF0D instead of 0xF00D as trap opcode. 1104: Do MMU "emulation" (no-op MMU instructions, probably many cases decoded 1105: incorrectly). 1106: 960627 New file LIESMICH, with minimal German instructions. Somebody want to 1107: translate the docs to French, Spanish, Italian, all the Scandinavian 1108: languages, Hebrew, Polish, Dutch, Russian, Welsh, Gaelic and something 1109: [email protected] understands? (No offense meant - I'm sure there are 1110: brillant minds using AOL. There must be.) 1111: 960626 In zfile.c, make sure we delete the temporary file even if file 1112: decompression fails. 1113: Reimplemented sound support, this time following the HRM closely. Seems 1114: to work fine most of the time, but occasionally loses drum beats in 1115: TFMX modules. do_sound() is now unconditional, it calls 1116: flush_sound_buffer(), which is system-dependent. This breaks everything 1117: except Linux sound for now :( 1118: Add Herman ten Brugge's 68020/68881 emulation code. 1119: FreeBSD chokes if sys/mount.h is included without sys/types.h. Fix the 1120: configure script. 1121: 960622 More work on AGA code. 1122: Removed 2-bit display routines from custom.c. Ian: please use dithering 1123: code. 1124: Make slowmem and chipmem sizes run-time configurable. 1125: Mask out the high bits in BLT?PTH(). 1126: Add exception 3 checks to Bcc/BSR instructions. Seems to be not quite 1127: correct yet. 1128: Completely rewrote the disk emulation. We now create a big track buffer 1129: full of MFM data, used in a cyclic fashion by DSKBYTR() and friends. 1130: The current position in the buffer is determined by the cycle counter. 1131: DMA reads are now done in one piece. Two new event types: ev_diskblk 1132: and ev_diskindex. 1133: ARRGGHH! The RSI demo has _completely_ broken disk loading routines. 1134: They start disk DMA on a block while the blitter is still working on 1135: the same memory region. 1136: In zfile.c, unlink() the temporary file directly after opening it so 1137: it will be freed by the OS as soon as we close it (or crash... :) 1138: 960621 Merge pfield_sprite_h() and pfield_sprite_l() into one function. 1139: Split off new files blitter.c and blitter.h from custom.c. 1140: Fixed null-pointer dereference in zfile.c when filename has no 1141: extension. 1142: Add new field maxline to gfxvidinfo that prevents writing past the 1143: screen buffer if it has less lines than expected. 1144: Modify the 256 color allocation routine to set nb_cols to the same 1145: value first for r,g and b; allocate everything as usual and fill the 1146: lost colors afterwards with those that have the greatest difference. 1147: 960620 For some extremely weird reason, it is faster to simply call the 1148: assembly-optimized pfield_linetoscr_full routines _twice_ to double the 1149: line than calling the new (also assembly-optimized) 1150: pfield_linetoscr_full_double routines, at least when writing directly 1151: into the framebuffer. If someone has a good theory why, let me know 1152: about it. 1153: Drawing into memory is faster with the _double routines, but not 1154: noticeably (about 1%). 1155: Consequence: Removed the new pfield_linetoscr_full_double assembly 1156: routines again. 1157: Add a "--disable-gui" option to configure. 1158: Add Samuel Devulder's dithering code. Provide support for mono and 1159: 16 color X servers. 1160: Put an assembly version of DitherLine() in X86.S. 1161: New color mode (3) available, tells UAE to use 256 colors and dither 1162: the image. This is meant for people who have only a 256 color X server 1163: available, but it works with the SVGA version, too. It's much slower 1164: than normal 256 color mode, though. 1165: Use the color allocation algorithm from the dither code in 1166: alloc_colors256(), too. 1167: 960619 New files: zfile.c and zfile.h, from Samuel Devulder. These provide 1168: transparent decompression of various compressed file formats. Enabled 1169: by configure only for Unix systems. 1170: Eliminate dont_want_aspect. New option "-C", sets correct_aspect. Make 1171: video mode 3 640x480, video mode 4 800x600. Honor correct_aspect in 1172: 320x400, 640x480 and 800x600 mode with SVGAlib. 1173: Add fields maxlinetoscr and x_adjust to gfxvidinfo. 1174: Rename pfield_slow_linetoscr() to pfield_do_linetoscr(). Use new fields 1175: in gfxvidinfo to enable writing directly to the framebuffer in 1176: resolutions with <800 horizontal pixels. 1177: New function pfield_do_linetoscr_full(), called when sure that full 1178: line update is being done. 1179: Move some of the usage() information into some target_specific_usage() 1180: functions, defined in the various system-specific files. 1181: Support lower resolutions with LOW_BANDWIDTH, too. 1182: memcpy() within screen memory is dog slow. Prevent some common cases: 1183: 1. Use fill_line() to double a line in the border. 1184: 2. Add a parameter to pfield_do_linetoscr_full() to indicate whether 1185: the line has to be doubled. New functions 1186: pfield_linetoscr_*_double_slow() that simply do a memcpy(), plus 1187: optimized ones in X86.S that are much faster by avoiding the copy. 1188: Smart update code could get confused by lores modes when 1189: prev_max_diwstop changed from one frame to the next. New variable 1190: frame_redraw_necessary, which acts as a counter. It's initialized to 1191: 2 in interlace mode to handle that case properly, too. 1192: Move sprite priority checks into pfield_sprite_?(), move HAM 1193: calculations into new function decode_ham6() to simplify the various 1194: linetoscr functions. 1195: Fixed a bug that would cause sprites to get deformed in some cases 1196: when they overlapped (never seen it). 1197: 960618 New file: dos-snd.c, from Gustavo. 1198: 1199: 960617 Release 0.6.0 1200: 960617 Fix memory clobber in X86.S when diwfirstword==0. Eliminate double test 1201: for HAVE_SYS_MOUNT_H in sysdeps.h. 1202: 960616 Handle programs that don't wait for the blitter by finishing a pending 1203: blit as soon as a blitter register is written to (regardless of DMACON, 1204: to be safe). 1205: Call gui_led only if the LED changed. 1206: 960615 Fixed dual playfield sprite priorities. Optimized dual playfield code 1207: in X86.S. More work on AGA code. Get joystick status only in 1208: vsync_handler to speed things up. 1209: Make blitter fill more intelligent with table lookups instead of loop. 1210: 960614 DOS update from Gustavo. Pass real bitplane pointer to 1211: bpl_data_differs(), don't calculate it again. 1212: 960610 Fixed silly INTEL_FLAG_OPT bug: The new __asm__ expressions use 1213: regflags, which is of course _regflags on a.out... 1214: More BeBox fixes from Christian. 1215: Make the CIA bank bigger (A0..BF) and relax the CIA A/B selection 1216: checks to make broken software (Kingsoft's Emerald Mine, reportedly) 1217: happy. 1218: Default framerate is now 1. 1219: 960603 New BeBox code from Christian. Fix test for ELF in configure.in. 1220: 960529 genblitter.c: generate blitfunc as a function taking ULONGs and 1221: returning an ULONG. This makes custom.o about 4500 bytes smaller on the 1222: x86 by removing worthless size prefixes, and should increase 1223: performance (better for the cache, and the P6 reportedly doesn't like 1224: 16 bit instructions anyway). 1225: memory.c: Load Kickstart in one block and swap bytes after that if 1226: necessary (eliminates the need for the special bebox load routine) 1227: custom.c: Some preliminary work for AGA support. 1228: 960528 Saw a real awful piece of code that detects the right mouse button by 1229: reading a value from POT0DAT, counting up to 25, reading from POT0DAT 1230: again, and deciding the button is pressed if the value changed. Urgl! 1231: Added POT0DAT() in custom.c ... 1232: Gustavo's latest patches. 1233: 960525 Do index pulse handling in CIA_hsync_handler(). Make sure bit 12 in 1234: INTREQ gets set on an index pulse. Don't call DISK_Index() for now, 1235: since this breaks the Workbench. 1236: The CIA code should _probably_ not be resetting the bits in INTREQ. 1237: Disable this as an experiment, let's see what breaks. 1238: 960524 Z flag handling for ABCD/SBCD/ADDX/SUBX was wrong (must be clear if not 1239: zero, was set if zero). Some other flag bugs in these functions fixed. 1240: 960523 gfxlib.c update from Christian Schmitt. Some new Mac code from Ernesto, 1241: still not all of it, though. Italian keyboard from Alessandro Bissacco. 1242: 960522 Fix the CHK instruction. Implement middle mouse button. 1243: 960515 Fix some Nextstep problems in configure.in. 1244: 960513 New Makefile target "streifenfrei" to remove all output from configure. 1245: Use autoconf 2.7; 2.9 is buggy. 1246: 960512 Remove BIG_ALIGNMENT hack. Remove superfluous pfield_fetchdata() call 1247: in pfield_doline_slow_l() that resulted in garbage on the screen. 1248: Move blttbl array from custom.h to genblitter.c 1249: Use new lookup tables imm8_table and areg_byteinc in CPU emulation 1250: instead of ?: expressions. 1251: GCC appears to generate better code if the opcode is passed as ULONG to 1252: the CPU emulation functions instead of as UWORD. 1253: Modify some of the flag emulation __asm__ statements so that GCC uses 1254: less registers for them. 1255: 960510 Cast malloc() results to char *, for C++ compilers. 1256: 960509 Use test for GCC and __i386__ in options.h to decide whether to use 1257: intel flag optimization. 1258: Use test for wish4.0 to decide whether to use the GUI. 1259: 960507 New bebox.cpp from Christian. AF sound patches from Marcus Sundberg. 1260: 960505 Fix the configuration stuff so it works. Fix some bugs in gfxlib.c 1261: 960504 Use GNU autoconf scripts to generate Makefile and sysconfig.h. Add new 1262: files sysdeps.h that includes the right system header files. Remove 1263: amiga.h and Makefile. 1264: 960502 More Next code from Ian (new Uae.app directory, 2 bit drawing for 1265: custom.c). 1266: 960501 Allow the sound driver to set the frequency to a value that is slightly 1267: different from the requested one. 1268: 960430 Added AmigaOS port from Olaf Barthel. 1269: 960427 Fixed single playfield sprite priorities in X86.S. 1270: 960426 Added new NeXTwin.m from Ian. 1271: Turn off the blitter delay in line mode. 1272: Added a CPU optimization from Olivier Raoul: gencpu now reads a file 1273: "insncount" that can be generated by UAE during execution and generates 1274: specific functions for the most common opcodes. Not documented yet. 1275: 960414 Reimplemented the fast disk emulation in a more sane way. Also it's 1276: only done for reads now. (Plus, it no longer works :-/ Need to work 1277: some more on this). 1278: In blitter emulation, defer not only the setting of the bltfinish bit, 1279: but actually defer the whole blit for the number of cycles it will 1280: take. This makes programs the clear the screen while it is still being 1281: displayed look much better. 1282: Changed supervisor mode handling around a bit (was messy). 1283: New DOS code from Gustavo. 1284: 960412 Removed smart update method 2. Added Alessandro Bissacco's blitter 1285: optimization patch. 1286: Fixed some sprite problems: during hysnc, clear sprpos and sprctl, and 1287: don't do_sprites() in line 0. 1288: 960409 Be a little more intelligent about when to call pfield_linetoscr() from 1289: pfield_doline_slow(). It's only necessary if a color register changed. 1290: If it can be deferred to the end of the line, use the the _full 1291: variants. 1292: Some CIA TOD fixes. 1293: Better transdisk, accepts first/last track parameters. 1294: 960405 New function memcmpy(), inline assembler for the i386. Compares two 1295: memory blocks and copies them at the same time. Used in 1296: bpl_data_differs. 1297: 960404 French keyboard from Tristan Cavelier. Parallel port emulation from 1298: Stefan Reinauer. 1299: Turn bpl?pt and r_bpl?pt into arrays, simplify some code using them. 1300: 960401 Some parts of Ernesto's new Mac sources. 1301: 960331 filesys.c: Close filedescriptors in free_key(). get_path() sometimes 1302: read uninitialized bytes. 1303: Minor cleanups all over the place. 1304: unchain_mnn() leaves sibling intact, but clobbers next. customreset() 1305: didn't care about that and crashed. 1306: Use the __asm__("intel_flag_lookup") magic not only for DOS. 1307: Support 320x300 for X (without LOW_BANDWIDTH). 1308: Add new function fast_memcmp(), defined as memcmp if __i386__ is 1309: undefined, otherwise a slightly optimized inline assembly function. 1310: 960329 Some bug fixes in gencpu.c 1311: 960328 Stupid programs write odd playfield modulos into the hw registers... 1312: Eek! Sometimes, linedescr[] was indexed with a negative value... Add a 1313: vpos >= minfirstline check to pfield_may_need_update(). I really need 1314: to rewrite this in Oberon... 1315: Don't turn off SHM when LOW_BANDWIDTH is selected. 1316: Keep the nextpos and linepos variables from pfield_doline_slow_?() as 1317: globals and initialize them in pfield_may_need_udpate(). 1318: Modified alloc_colors256() some more. 1319: Try to make sprite DMA follow the Amiga DMA slots more closely by 1320: adding a currhp parameter to do_sprites() and calling it at the end 1321: of a scanline or in pfield_may_need_update(). 1322: 960327 Added Gustavo's latest DOS code, as far as possible. Modified X86.S to 1323: use a macro SYM() to create symbol names either with underscore or 1324: without. 1325: Fixed some very silly SVGAlib lores bugs. Move screen 8 pixels up in 1326: low resolution. 1327: Use diwstop instead of diwstart to caclulate the DIW for 320x200 modes. 1328: Reset it not only in calcdiw(), but also in init_frame(). 1329: Speed up 256 color allocation a little bit. 1330: 960326 New function flush_block() in xwin.c and svga.c. Called from 1331: do_flush_line() and (new function) do_flush_screen(). Modify struct 1332: vidbuf_description, new member maxblocklines that records the maximum 1333: number of scanlines that do_flush_line() should collect before calling 1334: flush_block(). If it is zero, then flush_line() is used as before. 1335: This makes the special case stuff for SHM unnecessary, so it's removed. 1336: Fixed a stupid bug in events code: Put ev_hsync in front of ev_copper, 1337: so that do_copper gets called with hpos == 0 instead of hpos == 227 at 1338: the beginning of the line. 1339: New function init_frame() that sets up some variables, called from 1340: customreset() and vsync_handler(). 1341: Move smart update code to pfield_doline() from pfield_doline_h() and 1342: ..._l(). Clean up these two with a macro DO_ONE_PLANE, removing 1343: duplicate code. 1344: Implement big blits and ECS chip ids. New configuration options 1345: ECS_AGNUS and ECS_DENISE. 1346: Implement MOVEP. 1347: 960325 Before calling pfield_may_need_update(), make sure the value that was 1348: written to a register actually differs from the previous one. 1349: New expansion code from Stefan Reinauer. 1350: Modify struct mem_notify_node to contain a pointer to a valid bit 1351: instead of the valid bit itself, so that the playfield code has to 1352: check only one flag to decide whether to draw the line (SU method 2) 1353: 960324 The chip_flags approach has several problems. A flag may cover an area 1354: in memory that spans two scanlines, or several scanlines may use the 1355: same area in memory. 1356: Provide two other, different methods for the smart update: 1357: 1. Save all the bitplane data for each line and compare the chipmem 1358: with the saved data to decide whether an update is necessary. 1359: 2. Use a chain of memory_notify_node structs instead of a single bit 1360: for flags. Each scanline owns a set of these structs and chains them 1361: into the right place, and the chipmem_?put routines walk the chains 1362: and set the modified bit for each element. 1363: Unfortunately, both methods are slower than the old one. Especially the 1364: first one has some advantages though: it speeds up programs that clear 1365: the screen each update and write the same contents back, and it 1366: can speed up double-buffering programs at full framerate, since it does 1367: not have to check whether the bitplane pointers have changed. 1368: Remember the first and last drawn line for each frame, and pass them to 1369: flush_screen. Use this in xwin.c for SHM. Modify SHM logic: if smart 1370: update is selected, call XShmPutImage() from flush_line() instead of 1371: from flush_screen(). But gather blocks of consecutive lines to avoid 1372: calling XShmPutImage() too often. 1373: 960323 "Smart update" method, based very loosely on Alessandro Bissacco's 1374: work, implemented: 1375: Add an array chip_flags that records any change made to specific words 1376: in chip memory. 1377: Move all the hardware registers relevant to playfield display into a 1378: new structure bplinfo. Remember the contents of this structure in 1379: struct line_description for every line on the screen. Avoid redrawing 1380: in pfield_doline if the screen memory has not been modified for the 1381: line to be drawn and if the information from the last frame matches 1382: that in the current frame. 1383: 960322 Duplicate all functions responsible for drawing (pfield_doline, 1384: pfield_doline_slow, pfield_sprite, pfield_*word_*res) and append _h 1385: or _l (ah, the golden C++ days, when we had templates... which never 1386: worked). Modify the *_l functions to support drawing in low resolution 1387: (i.e. 320x200). Change the options -d and -H to support selecting color 1388: mode and resolution, thereby getting rid of some SVGALIB_* options. 1389: Get rid of the old pfield_*word_*res functions. 1390: Collect information about the minimum diwstart value during the 1391: previous frame and use that in case 320x200 was selected to fit the 1392: image on the screen. 1393: Get rid of HAVE_JOYSTICK (breaks the "-J" option) 1394: 960321 Give up in op_illg() if opcode is 0x4e7b and the exception handler for 1395: it is NULL. In that case, it's a 68020 Kickstart. 1396: 960319 New Next code from Ian. SunOS target was still screwed (two CFLAGS). 1397: Turn -x option into a "hair cursor" option. Support multiple mounts, 1398: but warn if more than one is seen (still does not work with Kick 1.3). 1399: Integrated Samuel Devulder's new LOW_BANDWIDTH patch. 1400: 960318 Integrated the start of Markus Gietzen's gfx library replacement. 1401: Changed the interface between custom.c and the graphics code. There has 1402: to be a buffer holding the data of all the lines on the screen. For 1403: linear SVGAlib modes, this is the video memory. Eliminated -x option, 1404: prepare_line(), DrawPixel() and the X_?BIT_SCREEN options, replace with 1405: 3 versions of pfield_linetoscr for different datatypes. Implement 1406: proper handling of the borders above and below the DIW in custom.c 1407: instead of in flush_screen(). 1408: Move common code (color allocation) from all the graphics files to new 1409: file gfxutil.c. 1410: Swedish keyboard from Per Olofsson. 1411: 1412: 960315 Release 0.5.0 1413: 960315 Newest DOS port from Gustavo. New sgi-gcc target. 1414: 960314 Add -lXext to osf target. Use "rb" for fopen() in main.c 1415: 960310 Play a bit with the __asm__ constraints. Implement CHK. 1416: 960307 Fix some stupid Makefile errors. Call parse_cmdline() if no init file 1417: is found. 1418: First round of NextStep patches; new file NeXTwin.m 1419: Stupid bug in custom.c: The #define is called NO_FAST_DISK, not 1420: NO_FAST_FLOPPY. 1421: Fix one of the problems the Deform demo had with the blitter: The 1422: line texture wasn't rotated to the right position in blitter_init(). 1423: 960306 Use some black GCC __asm__ magic to calculate flags more quickly 1424: (config INTEL_FLAG_OPT) 1425: HAM was broken by pfield_linetoscr changes. Fixed. 1426: LOW_BANDWIDTH sometimes got confused when the display window changed. 1427: 960305 BCD instructions work well enough for Locomotive Basic on CPE. 1428: New function parse_cmdline_and_init_file() that reads ~/.uaerc or 1429: ./.uaerc and adds the options found in those files to those in argv[]. 1430: Patch from Denis Sablic to make disk image filenames runtime 1431: configurable. Extend it for the ROM filename. 1432: Remove some of the run-time configurable stuff from config.h. 1433: More X keysym fixes (I finally got a proper .Xmodmap ...) 1434: for SVGAlib: Delete key, and PgUp/PgDn as Amiga keys. 1435: The sound driver can now handle 22050 Hz and/or 8 bit samples. Both of 1436: these are the default with LINUX_SOUND_SLOW_MACHINE. 1437: Also use the SNDCTL_DSP_GETBLKSIZE ioctl and write the buffer when 1438: there is enough data. 1439: Abuse keybuf.c to provide a fake joystick emulation with the numeric 1440: pad (enable with -J) 1441: 960304 bebox.cpp from Christian. 1442: Rename pfield_linetoscr_full to pfield_linetoscr_full8. 1443: More x86 assembly: pfield_linetoscr_full16. 1444: 960303 SunOS target from Dirk Vangestel. Put some not-so-superfluous includes 1445: back in. Added the DOS specific patches to filesys.c. 1446: Started x86 assembly optimizations. New file X86.S, includes an 1447: optimized version of pfield_linetoscr (for 8 bit screens only). 1448: Don't use SA_RESTART if it isn't defined. 1449: prepare_line() wasn't called often enough (again...), leading to memory 1450: corruption and "hit the reset button" bugs when using SVGAlib. 1451: 960226 Get rid of bool, true and false in amiga.h and everywhere else. 1452: Copy yesterdays code to AF_SOUND code, too. 1453: Include first round of Christian Bauer's BeBox patches. Add AIX fix 1454: from Samuel Mackrill. 1455: Add #include <string.h> and #include <stdlib.h> in some more places. 1456: Modify gencpu.c and readcpu.c so that immediate types j and J (0..15 1457: and 1..8) can be merged. Replace HAVE_ONE_GIG... option with a new 1458: CPU_EMU_SIZE option that can be set to a value in the range 0..5, 1459: where 0 is minimum size and 5 is equivalent to HAVE_ONE_GIG... 1460: 960225 Remove multiplications in sound code, use a big lookup table. 1461: 960222 Go back to having only one memory bank table of type addrbank instead 1462: of several function pointer arrays. Eliminate the HAVE_BROKEN_SOFTWARE 1463: define by extending the memory bank table to 65536 entries. 1464: Remove remaining DUALCPU code. Allow BTST src,imm instructions in 1465: table68k. 1466: 960220 Back out filesys.c change from Stefan Reinauer: don't call V36 specific 1467: functions in expansion.library. 1468: Better fix for the filesys.c assign problems by Oliver Moehrke. 1469: Make new playfield code conditional on EXPERIMENTAL_SCREEN_UPDATE. 1470: Improve the 64bit variant of said code. Try to get alignment for 1471: apixels by putting it into a union with a long. 1472: Kill the child in gui_exit(). Make graphics_init() return a value and 1473: check it in main.c to see whether graphics were initialized. If not, 1474: call gui_exit() anyway. 1475: Use new 256 color allocation routine from svga.c in xwin.c, too. 1476: Make LOW_BANDWIDTH compile _and_ work (wow...). 1477: 960219 Fix bug in memory.c: When loading 256K Kickstart, copy 256K, not 128K. 1478: 960218 Finished the rest of the UI: reset, debug and quit buttons as well as 1479: drive LEDs. New target linux-gui; all others use dummy file nogui.c 1480: for now. 1481: 960217 The GUI now supports inserting and ejecting diskfiles and displays 1482: their names. Two pipes are used now, one for reading and one for 1483: writing. Properly wait for the process to start up. 1484: Use sigaction() instead of signal() in debug.c. 1485: More fixes for the new display routines: Need to do a final call to 1486: pfield_*word_*res with the data shifted right from the last fetched 1487: word. 1488: 960216 Copper & sprite bugfixes from Marco Nelissen. Better X keyboard support 1489: from Bruno Coste. 1490: Move my_strdup() from filesys.c to options.h 1491: New files xui.c, uae-ui (shell script) and uae-ui.tk (wish script). 1492: These create a GUI for the X version of the emulator. So far, the 1493: power LED works. 1494: 960215 Don't rely on SVGAlib headers defining any keycodes at all. 1495: Include Thorsten Frueauf's NetBSD patch. Apparently, the devname 1496: variable in hardfile.c caused a namespace collision, so rename it to 1497: uaedevname. Fastmem fixes, debugger help, and ConfigDev allocation in 1498: hardfile and filesys from Stefan Reinauer. 1499: xwin.c: Give the window a title. 1500: Half-implemented the DIVU.L, DIVS.L, MULU.L and MULS.L instructions. 1501: 960213 AF sound system support from Marcus Sundberg. Win95 keyboard support 1502: for SVGAlib from Thierry Lescot. Added most of Gustavo Goedert's MS-DOS 1503: port. 1504: When using the old pfield_*word_*res functions, the gen_pfield_tables() 1505: function was undefined. 1506: Hmmm, /dev/brain must have been unmounted when I wrote the new pfield_* 1507: functions. Now they make sure they access the apixels array only with 1508: addresses that are multiples of 16 bytes. 1509: 960212 Fix copy&paste bug in cia.c found by Marco Nelissen: Need to call 1510: RethinkICRB() instead of RethinkICRA() for CIA B timers. 1511: Added Stefan Reinauers autoconfig area/fastmem support. Added run-time 1512: options for use_slow_mem and use_fast_mem. 1513: Oops, the pfield_*word_*res() optimizations break completely on HPs and 1514: Sparcs. Now use this optimization only if we are using GCC 2.7. 1515: HPUX fixes in the Makefile. New target hpux-gcc. 1516: The code for clearing the areas above and below the DIW was trying to 1517: be a little too clever selecting the color. Just use the current 1518: background color. 1519: Added channel attachment to the sound code. Untested. 1520: 960211 Found some flag setting bugs in the rotate/shift instructions and in 1521: addx/subx (which I thought I had already fixed) by reimplementing 1522: DUALCPU mode to work with Ed's e68k. 1523: Argh! The copper is completely disabled during DDF in Hires 4 bitplane 1524: mode - so copper positions 0x30 and 0x34 are about 640 pixels apart. 1525: The Kickstart uses FF39FFFE to wait for the end of line 256 instead of 1526: FFDFFFFE as in all the other modes. This is implemented now, but 1527: probably not 100% correct. 1528: Added check whether SVGAlib doesn't support our mode. 1529: If using GCC >= 2.7, define __attribute__((aligned(16))) as 1530: BIG_ALIGNMENT in config.h. Use it for the apixels array to prevent 1531: potential problems on the Alpha. 1532: Tried to make the color selection routine produce better results in 256 1533: color mode. 1534: 960210 readdisk didn't work at all for large files - fixed. 1535: In pfield_doline(), clear the apixels array if playfield DMA is off. 1536: In SPRxCTL(), reset sprite mode when sprpos==sprctl==0 1537: Rewrite pfield_orword_hires() and friends to use lookup tables. No 1538: noticeable improvement on my machine, but might be different on other 1539: machines. Two versions of this code: one using 64bit longs on the Alpha. 1540: New targets linux-debug and linux-prof. 1541: Use 1MB slow mem. 1542: -funroll-loops is a little excessive. Remove it. 1543: Add support for linear addressing modes for SVGAlib version. Speedup 1544: is 20-30% on my old 486 VLB. Now, would someone please fix SVGAlib to 1545: support that for the S3-864 as well? 1546: Set SVGAlib keyboard mode to DONT_CATCH_CTRLC. 1547: Change custom.c, xwin.c and svga.c to keep track of the display window 1548: and background color and to clear the areas above and below the display 1549: window if necessary to remove garbage images from previous frames. 1550: Set the LOF bit in the Kickstart replacement init routine. Also 1551: initialize CIAs to Kick 1.3-like values. 1552: 960209 Some more -DHAVE_xxx_H options in the Makefile and filesys.c. DEC Alpha 1553: fixes for filesys.c from Ed and Marcus. HPUX fixes. 1554: New field in table68k for CPU type, parsed by readcpu and compared to 1555: CPU_LEVEL which is defined in config.h. New instructions MOVE2C, MOVEC2 1556: and CAS. Also a new field for priviledge level that is used by gencpu to 1557: generate tests for regs.s and Exception(8) calls if necessary. 1558: Move parsing of table68k into a new file build68k.c. Generate a file 1559: called cpudefs.c containing the information from table68k in 1560: machine-readable form. Change readcpu.c to use the array found in 1561: cpudefs.c. 1562: Don't generate the d8(An,Dn) addressing mode in-line. Generate a call to 1563: get_disp_ea(), which is an inline function in newcpu.h if UAE is 1564: configured for 68000 emulation; for 68020 emulation, it is defined in 1565: newcpu.c. 1566: Debugger could crash on illegals because there was no mnemonic defined 1567: in lookuptab[]. 1568: Return zero for SERDATR. 1569: 960207 It seems that the copper stops completely if an attempt to write to a 1570: specific register fails because of COPDANG. Apparently, the Kickstarts 1571: use this to stop the copper with a 0x00000000 longword. This leaves the 1572: question why they don't do 0xFFFFFFFE like everybody else. 1573: Enable 512K slow memory by default. 1574: Integrate Stefan Reinauers battclock patch that makes it work with 1575: newer Kickstarts. 1576: In cia.c, do the little index pulse hack even if dskdmaen==1, because 1577: DMA is only enabled when dskdmaen==2 (Helps the "Mad Decision" demo). 1578: Add solaris entry to Makefile (GCC, Openwin, -DHAVE_STATFS_H) 1579: Define HAVE_STRINGS_H for SGIs, change filesys.c accordingly. 1580: 960206 Build a smaller table instead of cputbl.c. Use readcpu and the smaller 1581: table to build the cpufunctbl array at run-time. 1582: Nuked the other half of the old CPU emulator. Reimplemented debugger to 1583: use the information generated by readcpu. 1584: Define HAVE_STATFS_H for SGIs in the Makefile, and use that as a test 1585: in filesys.c instead of #ifndef __linux. 1586: Hack filesys.c, get_path() to support the assign command. 1587: Add -fstrength-reduce and -funroll-loops in Makefile to make people 1588: nervous. 1589: Rewrite Sam Devulder's LOW_BANDWIDTH patch and add it to xwin.c. 1590: 960205 Forgot some PC-relative bit instructions in table68k. 1591: Nuked half of the old CPU emulator. 1592: Split gencpu.c into two parts, new one is called readcpu.c and just 1593: parses the table68k file. Link it to the main program. 1594: 1595: 960205 Release 0.4 1596: 960203 filesys.c, action_read(): Slightly more efficient code (translate Amiga 1597: address to real pointer). 1598: Moved some common code in the generate_* functions in gencpu.c to a 1599: separate function. 1600: 960202 Added an experimental fast disk option. Currently turned off by 1601: default (it's not such a big win). 1602: Attached sprite fixes (overlapping att. sprites looked bad, Katakis). 1603: Add sleep(1) before resetting the console to text mode when using 1604: SVGAlib: this might fix some screen corruption problems. 1605: Add sprite/playfield priority checking to the most important case 1606: (single playfield, no HAM). 1607: In filesys.c, do_find(): open() returns -1 on error, not zero. 1608: Return ERROR_OBJECT_WRONG_TYPE if do_find() is called for a directory 1609: (fixes Champions of Krynn harddisk installation). 1610: 960201 Don't abort if sound driver not present, just set produce_sound to 0. 1611: New files keybuf.c and keybuf.h to record keypresses in the right 1612: order and without losing any. In cia.c, force 15 scanlines between 1613: keypresses, just to be sure. 1614: unixfs.device _does_ work with Kick 1.3: just don't trust what Kick 1.3 1615: sends in the startup packet. For now, disable more than one mount per 1616: command line. 1617: Started integrating Ernesto's new Mac sources. 1618: Remove superfluous includes from some files. 1619: 960131 Added Ed's unixfs.device (great stuff). 1620: Adding ULONGs to pointers is a bad idea on the Alpha if the ULONG value 1621: really is signed. Add some casts to LONG in (pc_p + src) expressions 1622: in genpu.c. 1623: If DMACON is written and copper DMA is enabled, do a COPJMP1 at once. 1624: Helps the "Interference" demo. 1625: 960129 More SGI fixes from Ed. Bugfixes and transdisk improvements from Marcus 1626: Sundberg. 1627: Remove EXTRA_DEFINES from Makefile. Breaks some systems. 1628: Move common sprite code from pfield_doline() and pfield_doline_slow() 1629: to new function pfield_sprite(). The same sprite may appear more than 1630: once on the same line, so don't shift out the bits of sprdata[] and 1631: sprdatb[] while displaying it (Turrican I). 1632: In xwin.c and svga.c, barf if LINUX_SVGALIB doesn't match the file 1633: being compiled. 1634: Make all .o files depend on config.h in the Makefile. 1635: No need to exit if sound driver unavailable, but -S given. 1636: Small debugger fix: Missing space in output. 1637: Fix for the sprite logic: Specifically, use a state variable indicating 1638: whether the sprite has been restarted after a VSYNC. Fixes most 1639: Turrican problems. 1640: 960124 Added Denis Sablic's patch for sound run-time option. 1641: Added Ed Hanway's patch for better Makefile, X mouse cursor blanking 1642: and more SGI compilation fixes. 1643: 960123 Include options.h everywhere. 1644: Handle 8 bit GrayScale visuals like PseudoColor. 1645: Remove C++ leftovers from joystick code. 1646: 960122 When using the joystick driver, the button test must come after 1647: handle_events() in vsync_handler(). 1648: 960118 Removed all the remaining C++ comments. Changed all inline keywords to 1649: __inline__. Define __inline__ if not using gcc. 1650: Make proper prototypes for everything. Compile with maximum warnings + 1651: -ansi + -pedantic. 1652: Remove CIA_cycle(), obsolete. 1653: Reimplemented the STOP optimization in newcpu.c. Removed DualCPU 1654: support in CPU emulator. 1655: Real nasty bug in pfield_doline() fixed: sprxpos could be evaluated as 1656: negative, with not-so-amusing results. (Need to rewrite this in 1657: Oberon to get array bounds checking :-) 1658: 960117 Heroic effort: Rewrote the thing in C. This might help fix some 1659: problems with users being unable to compile it. 1660: Fixed a problem in hsync_handler(): Only call flush_line() for lines 1661: in the display window, i.e. when we did a prepare_line() before. 1662: Better code for relative branches: Don't use setpc(getpc()+x) calls, 1663: increment regs.pc_p instead. 1664: 960116 Reimplemented the function to load the Kickstart ROM. Use stdio instead 1665: of fstreams since this apparently does not work on the Mac. Detect 256K 1666: Kickstarts. Detect corrupt ROM images (calculate checksum). 1667: Added Ernesto Corvi's Mac port. Changed it around a bit, so it 1668: probably won't compile. 1669: 960115 Reinstate config.h options for X screen depth, so that DrawPixel() can 1670: be inlined in custom.cc for speed. xlinebuffer is now incremented in 1671: each call to DrawPixel() (for both X and SVGAlib) to get rid of some 1672: address calculations. 1673: 960114 Fixed X generic pixel drawing routine for SHM. 1674: Still trying to fix the harddisk emulation. 1675: uae.device no longer breaks the debugger (can step through uae.device 1676: functions now) 1677: Bugs affecting performance: SPCFLAG_STOP never got reset, and DSKLEN() 1678: would set SPCFLAG_DISK even if DMA was being turned off. 1679: Made slow memory a run-time option. 1680: Defer interrupts by one CPU instruction to give programs a chance to 1681: read INTREQR ("Seeing is Believing" and "Substance" demos) 1682: Added ScrollLock hack for X, too. 1683: 960113 SVGAlib version compiles again. Fixed SVGAlib mouse bug. 1684: Fixed SHM bug: Maximum scanline is 313, not 312. 1685: Sometimes, disk.cc missed a side change and would read the wrong data. 1686: Fixed. Apparently, this was the worst compatibility problem. 1687: Implemented trace mode. 1688: 960112 Changed layout of class amigamemory a little so that gcc can generate 1689: better addressing modes. 1690: Finally wrote functions in gencpu to generate MOVEMs. 1691: 960109 Integrated Ed Hanway's patches for better X support and run-time 1692: configuration of some options. 1693: Got rid of the direct VGA memory access. (Need to do this differently). 1694: Changed the method of drawing lines: custom.cc now tells the graphics 1695: code the line number and whether it needs to be doubleed before drawing 1696: it. 1697: Added Andre Beck's MIT-SHM patch. 1698: Remove warnings for newcpu.cc. 1699: 960108 Fixed exceptions in op_illg(): Need to decrement PC. 1700: 960107 Added an "uae.device" resident module at 0xF00000. This emulates a hard 1701: disk (fixed size 8MB for now). 1702: 960106 Moved some common code from pfield_doline() and pfield_doline_slow() to 1703: a separate function. This fixes a potential HAM bug (two static vars 1704: for the same value). 1705: Sound support for Linux. Works only with graphics off and the CPU 1706: slowed down. 1707: Better SVGAlib keyboard support. 1708: 960105 Added AvailMem(), AllocMem(), AllocAbs() and FreeMem() dummies. 1709: The Hardwired demo times the multiplication instructions and prints 1710: "This demo don't like Axel" if they are too fast. Apparently, Axel has 1711: a 68040. Added a WANT_SLOW_MULTIPLY option to config.h. 1712: Fixed the fast blitter emulation (seems to work now). 1713: 960104 Fixed all the ChangeLog entries from 95 that said 96 (oops??!) 1714: pfield_may_need_update() should check whether bitplane DMA is on. 1715: Added ersatz.cc and ersatz.h. The purpose of these files is to 1716: implement one or two Kickstart functions that are commonly called from 1717: bootblocks. This should help support some games and demos that only use 1718: the Kickstart as an initial track loader. So far, it's only good enough 1719: for one program. 1720: 951223 More intelligent event handling in the CPU emulator. Slightly faster. 1721: 951222 Optimize CPU emulation by inlining cctrue(). Also, the real PC no 1722: longer needs to be incremented each instruction. The real PC value 1723: now has to be fetched by m68k_getpc(). 1724: Added direct screen access for SVGAlib, but it didn't help much. I'll 1725: probably remove it again. 1726: The gencpu executable is 2M smaller if it allocates memory 1727: dynamically. 1728: 951216 custom_bput() enhanced a little. Now remembers the value that was 1729: written in the other half of the register. 1730: Apparently, the USEx bits of BLTCON0 are ignored in line draw mode. 1731: (Silents-Demo) 1732: 1733: 951212 Release 0.3 1734: 951212 Included Alessandro's battclock patch. 1735: Fixed mouse autocalibration for wrong-aspect screens. 1736: 951210 Joystick support for Linux. 1737: Better color matching for 256 color modes. 1738: Rewrote most of the memory management in plain C, mainly to avoid the 1739: various template bugs in some compilers, but also because gcc can't 1740: handle the regparm attribute for virtual functions yet. 1741: 951209 Added Alessandro's patches for automatic mouse calibration. 1742: Tried to optimize the blitter loop a bit. Doesn't work. 1743: 951205 Added Hannu's patches for diskfile write support. 1744: 951201 More portability fixes, especially for weird compilers that workstation 1745: vendors ship. 1746: 951125 More keys for X, some keyboard support for SVGAlib (slightly 1747: dangerous); beginnings of US keyboard support. 1748: 951124 256 color mode support for SVGAlib. FAST! 1749: 951123 Tiny tweak to central loops in playfield code results in much better 1750: assembly. Apparently, GCC does not feel too good about optimizing 1751: reference variables. 1752: 951113 Bug fix in the events code (nextevent must not be changed while events 1753: are being processed). 1754: 951112 The playfield can now be drawn with the right aspect (i.e., every line 1755: twice). Slower, but looks nicer and supports interlaced mode 1756: (flickerfree!). The first 29 lines (blanking interval) are omitted 1757: now to fit everything in 800x600. 1758: Oops, disk drive identification did not work. Fixed, all four drives 1759: appear now. 1760: Oops, CIA_reset() was there all the time but never got called. 1761: Optimized the planar->chunky conversion in pfield_doline() a little. 1762: This really is time critical. 1763: 951111 If colors change on a line, we might still be able to use the full 1764: line update, if the change occurred outside the DIW. Have to be a 1765: little careful, though. 1766: Playfield code now uses real pointers again, but makes sure it can 1767: read enough bytes to complete the current line without segfaulting. 1768: Oops, my "better estimate" (see below) was a mistake. Restored the 1769: original 4 hw cycles per instruction relation. This slows down the 1770: emulator while booting (more screen refreshs), but speeds up many 1771: demos that otherwise spend most of their time waiting for a specific 1772: raster position. 1773: Playfield modulos must be added immediately when DDF stops. (WOC demo) 1774: Portability fixes in disk.cc (null pointers). 1775: Implemented average frame rate calculation ('c' in the debugger). 1776: Debugger fixes. 1777: Sprite fixes (height was wrong, wrong priorities in fast update) 1778: Added an AutoConfig expansion RAM device. The OS seems to recognize 1779: it, but breaks sometime later (seems to be the same bug that kills 1780: the emulator when there's RAM at 0xC00000). 1781: SVGAlib now has mouse support, too. 1782: HAM mode implemented. 1783: 951110 Implemented fast complete line playfield update. Switches back if 1784: necessary. Fixed attached sprites bug. 1785: Copper wait no longer slows down the CPU emulation. (there were 1786: lots of new copper bugs because of this, but I hope I fixed all 1787: of them). 1788: Changed cia?t? from UWORD to ULONG, since there were overflows in 1789: the assertion (because of 65535+1 == 0). 1790: 951108 The DIVS remainder could have the wrong sign. 1791: New HAVE_BROKEN_SOFTWARE define in config.h that makes the emulator 1792: mask out the high byte of all addresses. 1793: Wrote genblitter.cc and replaced the awful code in blitter_blit() 1794: and blitter_line() with calls to the generated function. 1795: 951107 Implemented ?BCD. These don't really work yet. 1796: 1797: 951106 Release 0.2 1798: 951105 Fixed a bug in the new CIA timer code. 1799: Fixed flag settings for some cases of ADDX/SUBX 1800: 951104 Changed the main loop a bit - call all the *cycle() functions only if 1801: it is really necessary. I hope everything still works - at least it is 1802: twice as fast now :-D 1803: Improved mouse emulation - avoid overflows, permit "wraparound". 1804: Added debugger 'g' command. 1805: Removed some useless casts from the CPU emulator. 1806: Added a configuration option to prevent checks for odd addresses. Only 1807: very bad programs need this check. 1808: 951103 The sprite emulation sometimes did not work too well, especially with 1809: dual playfield mode. Hopefully fixed. 1810: 951102 The 10 cycle counter is more like a 5 cycle counter in this 1811: implementation. (Fine, that makes floppy loading even faster :-) 1812: Implemented mouse movement. Totally out of sync with the X pointer, 1813: but at least something. 1814: Found out about the XAutoRepeatOff() function. Real useful. 1815: DualCPU mode works again. 1816: Corrected flag settings for CMPA.W. 1817: Fixed DIV instructions: Don't change dest in case of overflow. 1818: 951031 The PC is now converted to a real pointer. This is safe (much safer 1819: than converting bitplane pointers, since the PC always has to be valid) 1820: and should speed things up a little. 1821: 951029 Some primitive event handling: 2 mouse buttons and 1 joystick button 1822: are emulated, as well as parts of the keyboard (only german mapping). 1823: Fixes: Delay values and sprite widths are always LoRes. Playfield 2 1824: uses colors 9..15. 1825: Implemented a frame rate configuration option that can speed up the 1826: emulation quite a bit. 1827: 951028 A-ha. The 68000 has one strange feature after all. MOVEM.W to Dn sign 1828: extends the value to a longword. 1829: Katakis expects that accessing odd addresses causes exception 3, so 1830: we have to emulate this. *Sigh* 1831: Do at least something with the index pulse bit. It's more or less a 1832: toggle now. 1833: Implemented sprites & dual playfields, both with small glitches. 1834: 951027 When LOF is set, the frame is one line longer. 1835: 951026 Implemented a preliminary diskfile type for special formats. Turrican 1836: boots up correctly (crashes if I want to play a game, though). 1837: Implemented EHB and added a few missing masking operations in the color 1838: handling. 1839: Fixed the absw addressing mode - need to sign extend here as well. 1840: 951025 Fixed another extremely stupid bug, this time in the playfield code. 1841: Each pixel was calculated four times... 1842: Increased the size of the apixels array - this was being overrun. 1843: 951024 Fixed an extremely stupid bug in flag settings for byte and word 1844: operations. 1845: The "sectors until gap" field must be in the range 1..11 instead of 1846: 0..10, or very bad things will happen if it is used to calculate a 1847: blit size. 1848: 951021 Don't use real pointers to fetch bitplane data - too many segfaults. 1849: Delay the copper after executing an instruction, or wait sequences like 1850: FFDF FFFE 0200 FFFE won't work. 1851: Some programs expect that the CPU is completely turned off if the 1852: blitter nasty bit is set. So be it. 1853: The RSI Megademo chokes when disk DMA fetches two syncs. Leave one out. 1854: The LOF bit wasn't set correctly. 1855: 951020 Blitter fixes: Load fill carry from FCI each line; keep the masked 1856: value of bltadat in bltolda 1857: Give the CPU twice as many "cycles" - this still is not even remotely 1858: correct, but a better estimate. 1859: 951017 Added SVGAlib support. Unfortunately, my graphics card isn't fully 1860: supported by the current SVGAlib version. 1861: 951015 More small optimizations to memory.h and custom.cc. 1862: Added code for 256 color screens. The type of screen has to be 1863: selected at compile time. 1864: 951014 Modified the memory management to be (hopefully) a little more 1865: efficient. 1866: Changed gencpu.cc to generate functions and a big function pointer 1867: array instead of the old case labels. The generated C++ files now 1868: compile a lot faster, and the code should be better as well. 1869: 951013 Implemented pseudo POTGOR to keep the RMB from being detected as 1870: pressed all the time. 1871: GenerateDecTab() generated TRAP incorrectly. 1872: Made some more instructions (MOVE.B A0,D0 etc) illegal in gencpu.cc. 1873: Fixed X colors. Fixed data fetching for HiRes screens. 1874: 951011 EXT.WL instructions set the flags. 1875: Implemented second CPU emulator, plus "DualCPU" option. The new CPU 1876: emulator is generated automatically from a file called table68k by 1877: a program called gencpu. 1878: 951002 Removed version information from the file headers. 1879: Removed some sillinesses in custom.cc. 1880: DSKLEN bug fixed (mask out 0xC000). 1881: Playfield code rewritten. Now supports horizontal scrolling. Implemented 1882: some primitive color support. 1883: 950927 Fixed predecrement/postincrement addressing with byte size for the 1884: stack pointer. 1885: 950926 Fixes to the disk code: Terminate disk DMA, flip disk side, read more 1886: than just two sectors during disk DMA, fix checksum calculation. 1887: Fixed copper comparison bugs. 1888: 1889: 950901 Release 0.1 1890: 950826 bugfix in GenerateDecTab(): LEA.W instructions were generated. 1891: 950312 New file disk.cc, for (guess what) disk support. Doesn't work yet. 1892: 950311 Multiplication instructions were generating 16 bit results. 1893: Sign extension was wrong in some places. 1894: Removed bugs in the blitter (one word width: ALWM & AFWM and line mode) 1895: The Kickstart logo looks perfect now. 1896: Playfield routine should check BPLCON0 instead of BLTCON0 1897: 950309 ASR D8,D0 is not a valid instruction. 1898: Bitplane pointers were not incremented. 1899: Copper comparison didn't work. COP2LC and bitplane pointers were written 1900: incorrectly. Fixed. 1901: Something that bears a striking resemblance to the familiar Kickstart 1902: logo now appears in my X window! 1903: 950306 ROR used to set the X flag. Bug fixes in GenerateDecTab. 1904: More bug fixes in several 68000 instructions. 1905: Improved blitter. ?????? KS1.3 doesn't seem to set BLTDMOD on a 1906: line draw. What is this?? 1907: Fixed stupid bugs in playfield code. 1908: 950305 fixed bugs in opcode generation and interrupt handling. Implemented 1909: STOP. Fixed flag settings: Result wasn't masked. Ooops!! 1910: ADDQ #imm,An doesn't set flags. 1911: One-shot timer mode didn't work. 1912: Implemented blitter, doesn't work. 1913: Some primitive and slow playfield support, only to make the things that 1914: hopefully will soon appear visible. 1915: 950304 CIA timers ought to work OK. Copper is emulated. 1916: Emulator loops infinitely when trying to initialize the console.device 1917: 950303 experiments with X, figured out how to open a window and draw pixels. 1918: No graphics emulation yet, though. 1919: 950301 Nearly all instructions work. 1920: Fixed supervisor mode stack. 1921: The memory manager now handles CIA chips. 1922: 950228 Bug fixes in 68000 code, exceptions and more instructions implemented 1923: Memory management extended to handle custom chips as well. 1924: Debugger improved. 1925: Kickstart passes memory & CPU type test, builds up some system 1926: structures. 1927: 950227 MC68000 & little debugger for tracing. It can execute the first couple 1928: of KS1.3 instructions, but doesn't get past the memory test. 1929: 950225 Work begun
