1.1.1.4 ! root 1: 980629 MOVEP bug fixes (Philippe Gerin) ! 2: 980625 Make sure it compile when configured for DGA without VidMode. ! 3: 980606 Create config.h link in configure, not in Makefile. ! 4: xwin.c: Fix some dithering bugs. ! 5: 980601 Make ersatz.c a little more crash-proof. 1.1.1.3 root 6: 980508 Fix compilation problem on ELF systems introduced by BSD patches. 7: configure.in, aclocal.m4, Makefile.in: Use AM_PATH_GTK from gtk 8: distribution. 9: Don't disable GGI if we can't find svgalib. 10: 980504 xwin.c: Call XAllocColorCells for dithered modes. Don't set image_mem 11: in get_image, instead arrange for it to store the address in a pointer 12: chosen by the caller. 13: BSD patches by Krister Walfridsson. 14: 980425 picasso96.c: In BlitPattern, correctly handle the pattern offsets. 15: 980421 BeOS update (Christian Bauer) 16: 980419 In pfield_doline_unaligned_h, don't increment dataptr. 17: 980418 gtkui.c: Don't crash if -G option is given. 18: 980416 custom.c: Don't use bplhires in do_modulos. 19: 20: Release 0.7.0 21: 980401 gengenblitter.c: Complete rewrite. Much smaller, much faster, much 22: better results. 23: Check for -lXi to support newer versions of gtk+. 24: 980316 gencpu.c (read_counts): Two silly bugs fixed. 25: main.c (save_options): Don't write out 'a' if cpu_level < 2 26: configure.in: Changes to try to be compatible with Solaris /bin/sh. 27: 980315 New UAE-Control version from Tauno & Cloanto. 28: Make configure set UNALIGNED_PROFITABLE for x86. 29: Get rid of "-o", add save command to tui.c and gtkui.c. 30: Fix some bugs in save_options. 31: 980314 Many improvements in the gtk UI. Made CPU type changeable at run-time. 32: Make DGA && ! VIDMODE configuration compile. Kludge around the fact 33: that DGA misses colormap changes. Call XWarpPointer to try to avoid 34: the click-moves-framebuffer bug. 35: Make sure p2c.[ch] don't get deleted. 36: 980313 Move all CPU_LEVEL handling from build68k.c to gencpu.c. In gencpu.c, 37: ignore all parameters and don't write to standard output, instead 38: hardcode all filenames and generate them all at once. Arrange to 39: generate code for all CPU emulator variants and to select them at 40: run-time. 41: Get rid of copper cheat mode, re-use "-C" option for CPU selection. 42: 980312 In COPxLCL, mask out LSB (Axel Wefers). 43: newcpu.h: Always compile in both get_disp_ea versions with a different 44: name. Delete USE_POINTER option; always use pointer. Don't fill 45: prefetch in m68k_setpc, do it in callers where necessary. Compile in 46: two versions of get_ixxxx, with different names for prefetch and 47: non-prefetch. Change gencpu.c to use these appropriately. 48: Don't generate 16 small CPU emulation source files. With a decent 49: machine it's no problem to compile all the code in one file. Also turn 50: off -O3 for gcc, -O2 does fine since all the necessary __inline__s are 51: there, and the compiler takes less memory that way. 52: Don't include <linux/joystick.h>, duplicate some definitions from 53: there instead. Makes configure.in simpler, too. 54: Fix Makefile.in/configure.in and a couple of other places to support 55: building in a separate directory (sort of; not complete yet). 56: Remove p2c.[ch] and genp2c when doing make clean. 57: Delete code to support Tcl/Tk and XForms GUIs. 58: 971215 More Amiga and BeOS patches from Sam and Christian. 59: 971205 Move some more code from custom.c to audio.c.

Set FLOPPY_SPEED to 4. 77: 971107 Make ggi.c compile again, fix a few bugs and add Picasso support. 78: 971106 Fill prefetch queue after executing an encrypted ROM illegal insn. 79: 971105 Initialize the sprites during customreset now that init_hardware_frame 80: no longer does it. 81: 971104 Implement action_set_file_size as required by the specs. 82: SetPanning/picasso96_state: XOffset and YOffset are signed. 83: 971103 xwin.c: Offer 640x512 and 320x256 resolutions in windowed Picasso mode. 84: Add a few more memory banks in memory.c (A3000 stuff - nonfunctional) 85: Don't map kickmem at address 0 if using replacement Kickstart. 86: Must fill prefetch buffer when calling calltraps or ersatz functions. 87: Write out hardfile parameters in write_filesys_config(). 88: xwin.c: Support 15 bit displays. 89: 971101 Add latest patches by Samuel Devulder. Improve hardfile support in 90: tui.c. 91: 971031 Offer "-U" only ifdef PICASSO96. 92: Add support for mounting multiple hardfiles in any order. 93: Don't reset sprite state in init_hardware_frame. Instead, allow SPRxPT 94: functions to set the state to SPR_restart in the vertical blanking 95: area. 96: 971030 Fix 8MB Chip RAM. 97: filesys_dev_storeinfo: New function and calltrap. Use it to store 98: per-unit data (which now includes geometry information) in the 99: parampacket. Modify filesys.asm to use it instead of trying to find 100: the values by itself. 101: 971028 "AMIROMTYPE1" has 11 characters, not 0. 102: 971027 Implement encrypted ROM features. Comment out non-working InvertRect 103: optimization. 104: 971026 Fix some problems in PlanarToDirect and CopyColorIndexMappingA2U. 105: 971022 Remove fixed paths in genp2c.c (oops...) 106: Some more XF86VidMode hacks. 107: Include target.h in sysdeps.h. Define PICASSO96_SUPPORTED for X11, 108: SVGAlib and Win32. Don't compile in Picasso support if this macro isn't 109: defined. 110: 971021 xwin.c: Picasso code wants to use bit_unit, not bitdepth. Also correct 111: byteorder (it's B8G8R8A8 from the Amiga's point of view). 112: Fix Picasso InvertRect function. 113: Half-hearted attempt at 24 bit support in the X11 version, with some 114: awful code in custom.c. 115: Make the X11/VidMode version try to resize the screen for Picasso mode 116: switches. 117: 971020 Delete option -5, make -4 take an argument. Disable z3fastmem and 118: Picasso emulation when using a 24 bit address space. 119: 971019 record_color_change: No need to remember a color table if the current 120: line hasn't been decided yet. 121: Add XF86VidMode extension support. 122: Integrate Stefan's Zorro III support, add support for up to 64MB fast. 123: xwin.c: Refresh the whole Picasso screen if there are Expose events. 124: Fix module length calculation for *Tracker modules. 125: Use a 32 bit address space by default if CPU_LEVEL > 1. New option -5. 126: 971018 Apparently it's not possible to turn on bitplane DMA in the middle of 127: the line, so call post_decide_line only when the number of planes is 128: modified, not in DMACON. 129: genp2c.c: New file, generates planar to chunky conversion routines. 130: Remove those which are now generated from custom.c. 131: 971017 Make row_map an array, not a pointer to one. 132: Audio periods may not be 0, so initialize them to 65535 in customreset. 133: Implement "S" command in the debugger. Add a bunch of module detection 134: routines. 135: 971015 od-linux/sound.c: If FRAME_RATE_HACK, reduce vsynctime a bit to give 136: the sound emulation more room to breathe. 137: 971013 Merge with Brian's latest Picasso code. 138: 971012 Fix a few more portability problems that showed up when compiling with 139: Watcom C. Also remove superfluous includes from some files. 140: Add md-i386-watcom directory. Update od-win32 with latest code. 141: Remove fast_memcmp routine. 142: Include penguin.h before xwin.h everywhere. Declare a few semaphores 143: for multithreaded setups in xwin.h. Move inhibit_frame stuff to xwin.h. 144: 971011 gencpu.c: Don't generate labels without following statement. Don't 145: directly generate assembly statements if X86_ASSEMBLY, instead generate 146: code that uses macros defined in machdep/m68k.h. 147: 971008 xwin.c, svga.c, custom.c, uaelib.c: Add picasso96 code. Add Picasso 148: selection to configure. 149: Move common variables (mouse stuff, gfxvidinfo, xcolors) from graphics 150: files to custom.c. 151: memory.c: custom chip area isn't supposed to be mapped at 0x200000. Use 152: dummy bank for now. 153: od-linux/joystick.c: Open different devices for different joysticks. 154: From Win32 sources: set vsyncmintime in m68k_go. 155: 971005 genblitter.c: blitzero is initialized to 1, not to 0, so we need to 156: clear, not set it. 157: 970928 Add another user interface for X11 using libgtk+. 158: 970925 audio.c: For stereo sound, double all lookup table values. 159: Added (preliminary) win32.c. 160: 970923 DISK_check_change: Should call gui_filename when ejecting. 161: 970922 Fix od-linux/joystick.c compilation problem with recent kernels. 162: Merge results of the UAE meeting: 163: New serial code (Stefan Reinauer) 164: Expansion "test card" support (Stefan Reinauer) 165: New GGI code (Christian Schmitt), also configure/Makefile changes 166: to make it compile. 167: Fix 68020/FPU code. 168: Call do_mousehack before every read of the mouse position to get more 169: accurate values. 170: Add sd-file directory; add support for it in configure. 171: Add stereo support in audio.c, od-linux/sound.[ch], and main.c. 172: Fix copper problem: call decide_line in calc_copcomp_true; and if the 173: copper wouldn't wait normally (position reached), but the hardware is 174: fetching data in Hires 4 plane mode, delay until ddf stop. 175: t-ascii.h: Asciiart target understands "-x" parameter. 176: 970823 gencpu.c [X86_ASSEMBLY]: Turn input constraints for scratch into output 177: constraints. 178: 970626 Fix 24 bit address space logic (Mathias Ortmann). 179: Raise exception 3 for Bcc.L insns if CPU_LEVEL < 1. Reported by Stefan 180: Ropke. 181: Remove USER_PROGRAMS_BEHAVE for normal emulator. Remove hacks to 182: generate expanded CPU functions for specific opcodes. Replace with code 183: that reads an instruction count file and sorts gencpu output by 184: frequency of the called opcodes. 185: 970625 Calltraps (at least those with call_m68k calls in them) were broken by 186: the CPU emulator changes. Now use Axxx opcodes as calltraps. 187: Include pOS port by Samuel Devulder. 188: 970624 Solaris sound patches by Manfred Thole. 189: gencpu.c: The generated code shouldn't just check for odd addresses, 190: it should also call Exception... 191: 970622 gencpu.c: don't emit return statements; make code jump to a function 192: end label instead. Make genamode() check for odd addresses, also reduce 193: code duplication. Interpret getv parameter so that data is fetched if 194: getv == 1, and the address is checked if getv != 0. Remove exception 3 195: checks from get_long() etc. Get rid of buserr. 196: cpuopti.c: Make a few more checks whether optimization is possible. Add 197: code to undo GCC's epilogue scheduling. 198: newcpu.c: Split all the specialflag handling into new function. 199: Implement -w option as in Win32 port. tui.c: add it to misc menu. 200: 907621 Fix yesterday's CPU emulator changes. Make cpuopti aware of functions 201: with two RET insns. Make sure that NO_EXCEPTION_3 and 202: NO_PREFETCH_BUFFER are on when emulating a 68020. 203: Add usage information for src/dst operands to table68k. 204: Implement CIA A OVL bit properly. 205: 970620 New NeXTwin.m from Ian. Fix a number of prefetch bugs in gencpu.c. 206: newcpu.h: m68k_incpc(), get_i{byte,word,long}: New function/macros. 207: Also add oldpc parameter to m68k_do_[bj]sr(). gencpu.c: use all this. 208: CPU functions now don't use nextiword; they keep the PC constant and 209: increment it with the right value at the end. 210: If chipmem_size > 2MB, disable fastmem. 211: In configure.in and od-linux/joystick.c, use ljoystick.h as name for 212: the replacement file for a broken <linux/joystick.h> 213: configure.in: Check for post-gcc-2.7.2 option "-mno-schedule-prologue" 214: and use it for compiling the optimized CPU files if it exists. 215: 970618 Rename hardfile.device to uaehf.device to avoid name clashes. Suggested 216: by George Nicolaidis. 217: Reimplement CPU prefetch by making gencpu aware of it so it generates 218: code that fetches data from the right places automatically. Also reduce 219: prefetch length to 4 bytes. 220: 970612 memory.h: Include osdep/memory.h. missing.c: implement xmalloc(). 221: Throughout: use xmalloc instead of malloc. 222: Apply changes by Sam Devulder. 223: 970608 Fix ncurses.c so that it links. Fix configure so that it can be enabled 224: Get rid of spixstate by implementing a new sprite drawing method. 225: 970607 do_copper_cheat(): New function, Implement inaccurate, line-based 226: copper as an option (-C). calc_copcomp_true(): Fix possible hr 4 plane 227: bug (split the wait into several pieces in this mode). 228: Allow 0 bytes for fast and bogomem (to override .uaerc) 229: 970606 Fix some bugs in transdisk, and make it compile with SAS C (Joanne Dow) 230: Stupid compilation fixes: Get rid of "==" in shell scripts, check that 231: B300 and friends are defined in serial.c before using them. 232: Implement blitter prefetch. Fix silly typo in main.c that prevented 233: immediate blits. 234: init_ham_decoding(): new function, handles case where the first few 235: pixels of a HAM display are outside the window. 236: 970605 disk.c: Get rid of need_read. Save cylinder/track number for the data 237: in the MFM buffer for each drive. Force rereads on disk insert and 238: write operations. In drive_fill_bigbuf(), do nothing if saved data 239: matches current. Fix disk change logic: give the program time to read 240: the change bit a couple of times before inserting a new disk. 241: custom.c: Fix really subtle bug: when deciding a line as border, 242: plfstrt/plflinelen were not set up properly, which could confuse 243: post_decide_line(), and eventually there would be lines decided as 244: playfield with plfstrt == 0, plflinelen == -32 ==> Bang. A related 245: bug was that setting DDFSTRT to 0 would result in both plfstrt and 246: plfstop having value 0. 247: gfxutil.c: Fix bug that could cause color values to go out of bounds. 248: xwin.c, svga.c: When dithering, color values were not doubled properly. 249: 970604 filesys.c: when deleting an a_ino, remove it from hash table (Mathias 250: Ortmann). In do_find(), if creating a file failed and we didn't have 251: an a_ino before, call delete_aino on the one we created. 252: More configure changes: Add $X_PRE_LIBS and $X_EXTRA_LIBS in some 253: places. See if MIT-SHM support for X will compile and link. Always 254: compile it in if it will. Turn DONT_WANT_SHM and LOW_BANDWIDTH into 255: run-time options (-T, -L). Use single line buffer when dithering and 256: in low-bandwidth mode (but in all cases there's a full buffer for the 257: X image). 258: memory.c: Don't map in custom regs at 0x200000 if chipmem_size > 2MB. 259: Split up init_sound(): new function setup_sound(). Make "-B" accept 260: minimum and maximum values as in Gustavo's latest patch. Add code to 261: tui.c to support changing buffer size, number of bits and frequency. 262: 970603 If using compiler, define NO_EXCEPTION_3 and NO_PREFETCH_BUFFER. 263: (bugreport by Raphael Poss). 264: GGI support from Christian Schmitt/Stefan Reinauer. More serial patches 265: from Stefan. 3 button joystick patch from Mathias. 266: Add linemem field to gfxvidinfo, for systems that don't want to keep 267: a buffer of the full screen. Adjust custom.c to use it instead of 268: bufmem if it's not NULL (mostly by Mathias). svga.c, xwin.c: Use single 269: line buffer in some cases. xwin.c: If USE_DGA_EXTENSION, undef 270: LOW_BANDWIDTH. Move test of DONT_WANT_SHM after inclusion of config.h 271: Make configure.in a bit more structured. 272: Move colormodes array to main.c. 273: 970602 gfxlib.c: Start implementing layers workalike. 274: md-i386-gcc/support.c: Don't mix sleep and alarm. (Petter Schau) 275: 970601 Remove may_run_compiled. Print error and abort if m68k_go is called 276: twice. 277: Fix yesterdays bugfix in svga.c. 278: Change FRAME_RATE_HACK so it tries to average the times a bit. 279: Re-implement a call_m68k function in autoconf.c. The new version 280: works by doing some heavy setjmp/longjmp magic and switching stacks. 281: With this, it's even possible to call things that Wait(), so use 282: the new functionality in gfxlib.c to call LockLayer() in WritePixel(). 283: 970531 Turn some inline functions in memory.h into macros. Get rid of 284: get_along and get_aword. Implement CIA A OVL bit. 285: main.c: Add missing close_sound() call. 286: Remove INTEL_FLAG_OPT, use X86_ASSEMBLY for everything. 287: tui.c/svgancui.c: Implement scrollable menus. Add code to select 288: video mode from a given list. Add "graphics_setup" call to graphics 289: specific files. Use it in svga.c to build a video mode menu. 290: Fix bug in svga.c that would crash non-linear modes. 291: disk.c needs to include gensound.h and sounddep/sound.h. 292: Fix bug in fuzzy_memset. In pfield_init_linetoscr, always adjust ddf 293: values if lores hack is being used. 294: 970530 Apply some patches by Samuel Devulder. 295: 970529 filesys.c: In "Houston, we have a problem" case, do not only delete 296: the oldest ExKey, but also use it instead of random memory for the 297: new one. Attempt to reduce the number of lost exkeys by allocating 298: them in action_examine_next instead of action_examine_object. 299: Initialize the "uniq" field of unit->rootnode. 300: Attempt to speed up sprite drawing loop. 301: Implement sprite<->sprite collisions. 302: Get rid of -Wtraditional. 303: 970524 New config option NO_PREFETCH_BUFFER. Emulate 16 byte prefetch if 304: unset. 305: For exception 3, the stack frame seems to be: 306: (saved SR).w, (faulting address).l, (faulting instruction).w, 0.w, 307: (pc at fault time).l. Make everything that could generate this fault 308: handle it properly. That got Cybernoid II working! 309: 970523 Makefile.in: Make sure $(DEBUGFLAGS) is used for CPU emulation files. 310: memory.c: Don't map chipmem at 0x200000, use custom chip bank for now. 311: 970507 configure.in: Mutate ac_cv_c_inline=no to ac_cv_c_inline= 312: Check for tcgetattr, <sys/termios.h>, cfmakeraw, <sys/ioctl.h> 313: Check for sem_init in -lposix4 (Marc Zimmermann) 314: serial.c, cia.c, cia.h, serial.c: changes (Stefan Reinauer) 315: Make disk gap 360 (Michael Krause) 316: 970404 In configure, check for features.h before including it in test program. 317: 970401 New option -4. Bugreport by Mirko Viviani. 318: 970324 Petter Schau says the exception frame for Bus Error and Address Error 319: is 14 bytes, not 6, on the 68000. Change Exception() accordingly. 320: It's *** OUCH *** day! Make hardfile beginio return the correct value. 321: Also load execbase before calling ReplyMsg(). 322: It's *** OUCH *** day again! The filesystem asm code was an odd number 323: of bytes, leaving the hardfile code unaligned. 324: 970318 custom.c: Rename spron to sprst, and use new variable spron to indicate 325: for which sprites the sprite pointer registers have been written. Don't 326: do sprite DMA if spron==0. (The problem was that some programs write 327: SPRxCTL and then SPRxPT, which used to set the sprite state to 328: SPR_restart, but it must be SPR_waiting_start.) 329: Turn a few m68k_reset()s into uae_reset()s. 330: New variable nr_joysticks. Delete joystickpresent. New arg "nr" for 331: getjoystate() and read_joystick(). 332: New extra keycode AK_RCTRL. Handle multiple joysticks & different key 333: replacements in keybuf.c/custom.c. Make tui.c handle all the settings. 334: 970310 od-linux/joystick.c now compiles again without the joystick header. 335: Fix some problems in configure; also check whether [n]curses.h defines 336: attr_t. Keep count of warnings and errors during configuration and 337: print a hopefully helpful message at the end. 338: disk.c sanitized by Mathias Ortmann. 339: Change the replacement getopt around a bit. 340: execlib.c, timerdev.c: Files removed. This will never be compatible 341: enough. Also remove related code (several SPCFLAGs, etc.) 342: Make main.c a bit nicer by introducing additional defines for the t-* 343: files. Also canonicalize the .uaerc file on all systems, eliminating 344: lines starting with '#' in the process. 345: Remove code in autoconf.c to set up 8MB chip; move it to filesys.asm. 346: Try doing the copper end-of-line hack in copper_memory_cycles(). 347: Disable the copper speedup hack. 348: 970309 Add a small, dumb hash table to struct _unit to speed up repeated 349: aino lookups. Delete aino in action_delete_object(). Move children in 350: action_rename_object(). In action_examine_next(), call new function 351: lookup_child_aino_for_exnext() which behaves more or less like 352: lookup_child_aino(), except it uses new function get_aname() to 353: translate filenames. 354: More portability fixes. New links set up in configure: sounddep, 355: target.h. All machine-dependent and joystick code removed 356: from os.c, renamed to audio.c. os.h renamed to audio.h, joystick stuff 357: moved to joystick.h. New directory targets/. 358: missing.c: New file. 359: 970308 Rewrite filesystem. Now it keeps one unique "a_inode" structure for 360: every object in the filesystem. This contains Amiga name, native 361: name, Amiga permissions, lock counts and several links for building 362: a tree structure. Keys are now made only for files which need a fd 363: and a file position. 364: Treat invalid locking modes als shared. 365: Comment out the code using readdir_r because that function appears 366: to be broken in glibc-2.0.1. 367: Clear RES2 in all packets before handling them. 368: Give mousehack the same task priority as the input.device. 369: Fix (?) some silly bugs in disk.c. 370: 970307 Include some Acorn port code from Peter Teichmann. 371: Yet Another Serial Diff from Stefan. 372: 970306 filesys.c: Don't just crash if lookup_key() has no success. 373: action_find_write() is supposed to create the file if it does not 374: exist. 375: 970305 More DOS patches. Make the Makefile parallel-make safe. 376: svgancui.c: Do cyclic search if character is typed in file selector. 377: my_alphasort(): New function (work around glibc bug) 378: custom.c: Fix error in yesterdays change. 379: filesys.h: New file. 380: 970304 New serial patch from Stefan and Christian. 381: Remove the assembler code to generate inputevents. Instead, add a new 382: Amiga C program ("mousehack") which does the trick. New function 383: mousehack_helper() in custom.c, activated by calltrap 0xF0FF70. 384: Mouse default is now always normal_mouse, not follow_mouse. 385: Do disk change checks only every 1/2 second. disk.c: Reverse 386: nodskchange to dskchange, and make sure there has been a step with the 387: drive empty before calling drive_insert() from DISK_check_change() (but 388: this _still_ doesn't work. Arrrghh). 389: 970303 filesys.c: Initialize _all_ of struct _unit in startup_handler(). 390: Remove message_lock and friends and use new variables cmds_sent, 391: cmds_acked and cmds_completed to determine when to send dummy messages. 392: Changed examinekey handling so that "dir all" on a large tree doesn't 393: crash anymore (it used to reuse the top-level exkeys which were still 394: in use after a wraparound). Don't allocate examinekeys if we're 395: examining files. 396: Check for readdir_r in configure. Use a wrapper my_readdir() around 397: either readdir or readdir_r. 398: Call filesys_reset() also from filesys_diagentry(). 399: Get rid of most of uaelib.c. Now there isn't a library, just a calltrap 400: at 0xF0FF60. Changed uae_pragmas.h accordingly and recompiled uaectrl. 401: Added a bunch of "volatile"s in various places in filesys.c and 402: penguin.h. 403: Make the filesystem reset-safe in the threaded case (paranoia changes). 404: Check disk changes only every 1/10 second in vsync_handler(). 405: Add assembler code to generate InputEvents once every vblank to 406: filesys.asm. (Doesn't work yet.) 407: 970302 filesys.c: Get rid of DosPacket type, pass pointers into Amiga memory 408: instead. Use GET_PCK_* and PUT_PCK_* macros to access fields. 409: Start making filesystem code thread safe & multithreaded. Move static 410: variables from some functions into struct _unit, likewise the key 411: and exkey variables. Add code to filesys.asm to queue commands which 412: did not complete and to reply to them later. Do multithreading if 413: compiled with SUPPORT_THREADS. See source for details. 414: Change hardfile and uaelib code not to call 68k routines. Make emulator 415: traps more efficient (no need to save regs, don't need SPCFLAG_EMULTRAP 416: anymore). 417: 970301 Fixed ncurses.c so it works with currprefs. 418: filesys_reset(): New function, called from customreset(). 419: Changed source layout. Break up machdep into machdep, osdep and 420: threaddep. 421: penguin.h: Now supports arbitrary types in pipes. 422: Changed filesys.c so that no 68k code is called from native C code. 423: filesys.asm, filesys.sh: New files. filesys.asm contains some 424: startup code and the main loop for the filesystem. Several locks 425: are allocated by the assembler code for use by the C code. 426: DOS_AllocMem(), DOS_FreeMem(), make_dev(), build_parmpacket(), 427: filesys_init(): Functions removed. 428: 970228 ncurses.c: Fix problem in b/w modes. 429: finish_drawing_frame(): Don't need to draw lines in multipenguin mode. 430: Move all options into new struct uae_prefs. New variables currprefs, 431: changed_prefs. 432: svgancui.c, tui_filereq(): If user presses a key, start search at 433: current position, not at the beginning. 434: DISK_check_change(): new function, compares currprefs with 435: changed_prefs and handles diskchanges if they differ. Called from 436: vsync_handler(). 437: DISK_validate_filename(): new function, checks whether a file exists. 438: Modify svga.c and tui.c so that F11 now brings up a limited UI. 439: 970227 Reimplement Mathias Ortmann's frame rate hack: New option HAVE_RDTSC 440: in config.h. New typedef frame_time_t. New variables vsynctime and 441: vsyncmintime. New function machdep_init() in md-*/support.c which 442: sets up vsynctime in the md-i386-gcc and md-i386-linux cases. Use 443: all of those in events.h, do_cycles() to determine whether to spend 444: more time on the CPU emulation. 445: Add missing "int i;" to xwin.c, init_colors(). 446: Unroll some loops in sample_*handler(). 447: Improve quitting/resetting behaviour: Move quit_program from GUI 448: specific files to main.c. New functions uae_reset() and uae_quit(), 449: quit_program is now handled in vsync_handler() and m68k_go(). 450: New variable sample_evtime, used in customreset() and set up in 451: init_sound(). 452: 970226 Solaris sound update from Manfred Thole. 453: keybuf.c: Decided that it doesn't need locking after all. 454: Add a bunch of Gustavo's latest diffs. (I hate CR characters!) 455: Move gfxvidinfo from all the target-specific files to custom.c 456: More Win32 stuff: New function notice_new_xcolors(). 457: 970225 configure.in: In shell string comparisons, always put spaces around = 458: Add warning about standard SVGAlib being incompatible with 459: LinuxThreads. 460: os.c, SOLARIS_SOUND: Remove reference to obsolete variable smplcnt. 461: Two new variables sound8_base and sound16_base. 462: sysdeps.h: Split off some stuff into md-amiga/amiga-kludges.h. Also 463: make the main types now uae_u32 and variants instead of ULONG, etc. 464: Convert some files to use the new types. 465: cia.c: use int/long instead of ULONG/UWORD/etc for most static vars. 466: xdebug.c: Some cleanup. 467: md-i386-linux/penguin.h: Fix bug. Add "chunks" parameter to 468: init_comm_pipe. Use it to decide in write routine whether to signal 469: the other thread if it's waiting. Add no_buffer parameter to 470: write_comm_pipe_int. 471: Start adding Mathias Ortmann's Win32 patches. 472: md-i386-win32: New directory 473: include/sysconfig.h.win32: New file 474: custom.c: is_lastline: new variable, set in hsync_handler(). 475: sysdeps.h: Make it possible for system specific code to say that 476: POSIX/ANSI stdio/malloc functions aren't present and are defined 477: by a system-specific file instead. In filesys.c, don't reference 478: errno if DONT_HAVE_POSIX is defined. 479: readcpu.h: Kludge around the fact that Messysoft C apparently doesn't 480: handle enums properly. 481: newcpu.c/sysdeps.h: Preprocessor magic for 64 bit constants to get 482: around a problem with MS C. 483: md-*/penguin.h: Add dummy definitions for semaphores. 484: keybuf.c: Use semaphores to synchronize access. 485: os.c, win32 sound stuff: add memcpy avoidance code. 486: 970221 X86.S: Don't use .type ifdef USE_UNDERSCORE. 487: Move thread support configuration to configure from config.h. Change 488: pipe implementation to use POSIX semaphore functions. 489: 970217 From Samuel Devulder: Fix off-by-one error in LINE_TO_SCR, EHB case. 490: 970215 customreset(): Initialize current_colors.color_regs to invalid values 491: [reported by Samuel Devulder]. config.h: Uncomment ECS_DENISE [reported 492: by Mathias Ortmann]. Add ami-win.c and custom.c patch from Samuel 493: Devulder. 494: 970213 disk.c: Set FLOPPY_SPEED to 3 495: custom.c: SPRxCTL_1(): if spron was SPR_restart set it to 496: SPR_waiting_start. do_sprites(): don't do that. 497: SPRxPT{H,L}: Call decide_line(). 498: 970210 custom.c, X86.S: Do LORES_HACK for dual playfield screens. Plug memory 499: leak in custom_reset(). Fix pfield_draw_line() not to do so many 500: multiplications. Make line_changed a char array. In remember_ctable(), 501: remember comparison results also if negative. 502: In 8 and 16 bit graphics modes, use the high parts of the color values 503: to duplicate the actual values. This saves a lot of code in the 504: hdoubling routines. Add a special fill_line in the X86_ASSEMBLY case. 505: Check for glibc-2 and libpthread in configure. 506: options.h: In fuzzy_memset(), do rounding slightly more conservative. 507: Add tons of new keycodes to svga.c 508: In record_color_change(), also check if vertically outside DIW. 509: New variable hdiwstate, to represent the horizontal DIW state machine 510: (thanks Petter!) Handled in reset_decisions(), finish_decisions() and 511: decide_diw(). 512: 970209 Change ncurses.c not to do so many multiplications/divisions. Add bold 513: character support. Add color support. Make configure recognize 514: --without-svgalib and enable ncurses.c in that case. 515: 970208 X86.S, custom.c: Do LORES_HACK for EHB screens also. 516: New function write_log(); convert some fprintf(stderr, ...) calls. 517: 970207 Argh, Linux/i386/ELF check in configure got broken by latest sh-utils. 518: In disk.c, drive_reset(), clear nodskchange flag. 519: 970206 Sprite fix from Mathias Ortmann: _really_ get rid of SPR_vtop, and 520: replace all uses by SPR_stop. 1.1.1.2 root 521: 970204 Disk change fix from Mathias Ortmann. 522: 970203 New file ncurses.c, from Samuel Devulder. 523: Disabled Exec stuff completely. Now it isn't even compiled in anymore. 524: 970129 Changes from Samuel Devulder for Amiga and Christian Bauer for BeBox. 525: 970122 Reorder the set_planes_unaligned functions so that better code is 526: generated. Remove the or_planes_unaligned functions, add a parameter 527: do_or to the set_planes functions and rely on the compiler to optimize 528: the additional if away. 529: post_decide_line() can now turn DMA off early. 530: Make struct flag_struct 64 bits large for i386 systems, so we can use 531: long move insns without clobbering the X flag. 532: "make clean" should delete machdep/support.o. 533: Maybe we do need SPR_vtop after all - undo 970120 change. Instead, 534: comment out the code that clears the pos and ctl words at vsync time. 535: In xwin.c, restrict window height to 300 or 600 depending on linedbl 536: mode. 537: 970121 Get rid of SPCFLAG_BLIT, call do_blitter() directly. 538: In finish_decisions(), don't check for sprite draws in the border. 539: Reimplement the SMART_UPDATE define so that the memcmpy() overhead can 540: be avoided by not setting it (but this usually loses). 541: Detect 7 lores planes in BPLCON0() and change to 6 to avoid memory 542: clobbers. 543: In pfield_draw_line(), do memcpy linedoubling after handling the line 544: to be doubled, not when we see a LINE_AS_PREVIOUS. Get rid of prev_ypos 545: parameter. 546: Add special code for bpldelay1 == bpldelay2 to the UNALIGNED_PROFITABLE 547: code. 548: In pfield_init_linetoscr(), when delays 1 and 2 differ, clear the areas 549: which are covered only by half of the planes at the start and end of 550: the DDF area. 551: Replace FASTER_CPU and LINUX_SOUND_SLOW_MACHINE with M68K_SPEED. 552: Replace fast_unaligned_memset macros with fuzzy_memset; use this also 553: in pfield_init_linetoscr(). 554: Use real (PAL) vblank end in do_sprites(). 555: 970120 Mask out high byte in DDF{STRT,STOP} 556: Oops, forgot about long frames while calculating the bounds of all the 557: maxvpos*2-sized arrays. Increment them all by two. 558: Try to detect empty sprites before recording them for the drawing code, 559: but be careful not to hurt attached sprites. 560: From Paul Kienitz: hack for keyboard code in cia.c to work better with 561: newer Kickstarts; small cleanup in cpuopti.c. 562: Undo yesterday's change in copper_memory_cycles(), instead call 563: decide_line() each iteration and test whether copper_cycle_time == -1 564: to determine whether we're vertically in the DIW. 565: calculate_copper_cycle_time() could get astronomical plane counts due 566: to missing masking operation. 567: No need to put the copper to sleep for one memory cycle after a WAIT, 568: merge that with the two cycles for the next instruction. 569: Get rid of SPR_vtop, no longer needed (it was unnatural anyway) 570: 970119 Implemented alternate pfield_doline functions that access the apixels 571: array at unaligned addresses; conditional on UNALIGNED_PROFITABLE. 572: Move LORES_HACK from config.h to custom.c. 573: Fix loop exit test for pfield_linetoscr_hdouble_asm8(). Clear the 574: right parts of apixels in pfield_init_linetoscr() when LORES_HACK is 575: enabled. 576: Get rid of bordercol array: the decision-making code should handle 577: lines in the border correctly by setting line_changed. 578: Disable bitplane DMA if more than 4 hires bitplanes are set in BPLCON0. 579: Fix some more copper timing inaccuracies: used to test 580: thisline_decision.which without calling decide_line() before. 581: 970118 Now remember BPLCON1 changes during data fetch. New functions 582: decide_delay(), pfield_adjust_delay(); new fields in struct drawinfo 583: and new variables next_delay_change, delay_changes. 584: Forgot to set copstate to COP_morewait in one case in do_copper(). 585: Add a kludge that checks for copper position 0xDC and changes it to 586: 0xDE. 587: Restore equality test for vertical sprite positions. Disable sprite 588: DMA before the end of the vertical blank area. 589: Mask not only the positions, but also comparison values in 590: calc_copcomp_true(). 591: 970117 Change custom_bput to put the byte value in each half of the word that 592: is put. 593: 970116 disk.c: Set the gap between sector 11 and 0 to 380 words. Andromeda's 594: "Seven Seas" demo expects at least 320. Make the KILLEHB bit 595: conditional on AGA_CHIPSET. Decide BPLCON1 (scrolling delays) in 596: decide_diw(). Fix off-by-one errors in the very_broken_program case 597: of decide_plane(). Fix aspect calculation when horizontal resolutions 598: differ. Simplify copper horizontal comparison logic slightly. 599: Fix divide by zero errors when reading from empty floppies. 600: 970115 pfield_draw_line(): Check for frame_redraw_necessary also for border 601: lines. New global variable pfield_last_drawn_line, used to implement 602: clever Y centering. Make the KILLEHB test conditional on ECS_AGNUS. 603: Move joystick and sound initialization before gui startup. Adapt tui.c 604: so it understands the gfx_requested_* options. 605: We can't always avoid clearing pixdata.apixels if DIW is larger than 606: DDF. There may be sprites in the area outside DDF, but inside the DIW, 607: so we can't just adjust linetoscr_diw_{start,end} blindly in 608: pfield_init_linetoscr() [Sanity Arte demo]. 609: 970114 Bebox diffs from Christian Bauer. 610: Support for Symmetric Multi Penguins under Linux (start second thread 611: with clone and use some pipes for communication - rather simpleminded 612: for now). Rework do_flush_line() and do_flush_screen() so that X 613: libraries are only called from the first thread. 614: Eliminate valid field from struct decision (set which to -2 instead of 615: valid = 0) 616: Fix definition for gui_filename() in xdebug.c to use const char * for 617: the second parameter. Remove CRs from disk.c (now how did they get in 618: there??). Likewise for cpuopti.c. 619: 970113 When post_decide_line() detects mid-line DDF change, must adjust 620: bitplane pointers in decide_plane() also. Make plfstrt the earlier a 621: position in this case, and adjust bitplane pointers/modulos 622: accordingly. 623: current_hpos() isn't what GCC calls a constant function. 624: Replace line_drawinfo[current_change_set] with new variable 625: curr_drawinfo throughout. Likewise for new variables prev_drawinfo, 626: {curr,prev}_{color_{change,table}s,sprite_positions}; all initialized 627: in init_drawing_frame (). Turn line_data into a 2dim. array, do some 628: CSE/SR on line_data[lineno] in pfield_doline_{l,h}() and 629: decide_plane(). Make some custom registers unsigned int instead of 630: UWORD. 631: calc_copcomp_true(): Masking with 0xF000 isn't likely to give 0xC0000. 632: Comment out bplcon{3,4} from struct decision. 633: 970112 filesys.c, action_set_protect(): if __unix is defined, check whether 634: user wants to change directory protection, and if so, force rwx to be 635: the new protection. 636: Force sane window sizes in xwin.c, and set width/height from mode specs 637: in svga.c. 638: Implement LORES_HACK compile-time option. 639: Whee, there _are_ broken programs that enable bitplane DMA in the 640: middle of the data fetch area, draw half a picture on the first line 641: and the full picture on all subsequent lines. New function 642: post_decide_line(), called from BPLCON0() and DMACON() which tries to 643: detect this case and turns the decision from border to playfield if 644: necessary. 645: New arrays, sprvstart and sprvstop, calculated in SPRxPOS and SPRxCTL, 646: and used by do_sprites. Handle sprites with vstart == vstop correctly. 647: Sprite vpos comparisons are now done with <= , not ==. 648: _Now_ the X86-specific linetoscr routines do their masking correctly. 649: configure: If we have GCC, #define GCCCONSTFUNC as __attribute__ 650: ((const)) 651: 970111 Eliminate can_draw from struct decision. 652: Change vertical DIW code; use enum of two states (waiting for start and 653: for stop) which is updated in decide_line(). Lines during the wait for 654: stop phase are decided as border. No data is fetched outside the 655: vertical DIW. 656: Optimize copper memory cycle calculation a little: the new variable 657: copper_cycle_time is set to a time >= 0 if this time is constant 658: (i.e. 2). Calculated whenever DMA, BPLCON0, or DIW state changes. 659: blitter.c, genblitter.c, custom.c: For BLTBDAT, follow the HRM which 660: says that immediate data is shifted as soon as it is written. This 661: seems to be wrong for the A channel, though. Also, don't change prevb 662: during blitter loops if DMA B is off (Sanity Arte). Turn FAST_BLITTER 663: stuff into run-time option "-n", and eliminate the ancient blitting 664: code (former FAST_BLITTER == 0). 665: Big OOPS: Copper move checked copcon, but there was no COPCON function 666: so it was always zero -> copper-controlled blitter never worked. As a 667: speed optimization, recognize 00010000 copper commands and put the 668: copper to sleep until the blit is finished. 669: Slow down the blitter in decide_line() if bitplane DMA steals blitter/ 670: copper/CPU cycles (but this code is commented out for now). 671: 970110 New function pfield_init_linetoscr(). Move calculation of diw_end and 672: diw_start values there from x86-specific code. Also use DDF values to 673: determine where data in pixdata.apixels is valid. The x86-specific 674: linetoscr routines now only do the alignment masking (and they now do 675: it correctly, too). 676: Got rid of the display-related contents of struct draw_info, make 677: static variables and them initialize from pfield_draw_line() only when 678: necessary in function pfield_expand_dp_bplcon (). Get rid of the four 679: saved_* arrays, remember line_drawinfo instead now that it's smaller. 680: Color compare avoidance didn't work because color_src_match didn't get 681: set when a compare was successful. Fixed. 682: Reorder parts of the decision-making code so that less redundant checks 683: are performed. 684: Add clever x centering. Change "-O" option parameter format. 685: In md-i386-linux/support.c, memcmpy(), do memcmp() first, then switch 686: to a plain memcpy routine once we find the first difference. 687: Patches from Stefan Reinauer/Christian Schmitt for 688: xdebug.c/configure.in 689: New uae-ui.tk from Volker Zota. 690: Add --enable-profiling to configure.in. 691: Check for period==0 in AUDxPER() was accidentally commented out - 692: revert. 693: 970109 Some tweaks in X86.S, plus a new option X86_PPRO_OPT to use movzbl 694: instead of xorl/movb when possible. 695: Fix maxline calculation in finish_drawing_frame(). 696: Make next_lineno always a valid array index. Decrease minfirstline to 697: 21 (NTSC vblank end). New option -O to specify display parameters, 698: supersedes -d and -C which will be removed eventually. Differentiate 699: between line doubling and aspect correction. Put aspect correction code 700: in custom.c. 701: Remove some more unused stuff from custom.c. 702: Fix Makefile problems when cpuopti isn't used. 703: 970108 use_lores isn't initialized before custom_init(), setup lores_frame and 704: friends in customreset(). Optimize spixstate clearing. Optimize border 705: drawing with copper color changes (use fill_line instead of linetoscr) 706: Fix the sprite DMA logic, it now works with the Interference demo. 707: Silly bug: Sprite 7 never got displayed (introduced sometime last week) 708: Implement USER_PROGRAMS_BEHAVE for normal (non-compiler) CPU emulation. 709: Add most of Gustavo's last patch (new dir md-i386-dos) 710: 970107 Finish rewriting most of the drawing code in custom.c/X86.S. See 711: README.PROGRAMMERS and source for details. Improvements include better 712: copper precision, better interlace support, hopefully much less bugs 713: and not too many new ones. 714: Remove calc_adjustment() and gfxvidinfo.x_adjust; replace with code in 715: custom.c that looks at gfxvidinfo.follow_diwstop (new field) 716: Some operations (like EHB playfields) now have a higher penalty than 717: before, the assumption being that these are rare and the normal case 718: runs faster if it doesn't have to care too much about exceptions. 719: Fix sign mismatch bug in BPL1MOD() and BPL2MOD(). 720: 970104 Move x_ShowEA() from xdebug.c in newcpu.c, rename as ShowEA(). 721: 970102 Add check for XK_W to decode_es() in xwin.c. 722: New uae-ui.tk from Volker Zota. 723: 961218 Add a patch by Bernie Solomon to overcome a problem with K&R compilers. 724: Change X86.S in a way that may make it either faster or slower. 725: Fix ADF_EXT1. 726: 961217 #ifdef XK_dead_*, since Solaris doesn't have it. 727: 961202 Fixed joystick.h problem in configure. X11/DGA support from Kai 728: Kollmorgen. 729: 961117 Some fixes in svgancui.c. 730: 961112 Gustavo's latest patch, with GUS support for DOS by Michael Sontheimer. 731: Add menu browsing to tui.c/svgancui.c 732: 961107 Fix m68k_areg and m68k_dreg macros (put args in parentheses) 733: Initialize gfxvidinfo.maxlinetoscr in xwin.c (found by Sam Devulder) 734: 961104 svgancui.c tui_refresh() routine tweaked to work with the non-standard 735: ncurses that came with my new SuSE-Linux CD. 736: 961031 Added Christian Schmitt's xdebug.c (disabled for this release) 737: 961024 Module search function from Michael Krause. 738: 961019 Add Samuel Devulder's Amiga patches. 739: 961018 Don't use -lm on NeXTStep. 740: 961017 configure checks for -lforms. 741: 961016 Ian Stephenson's new NeXTwin.m. Make CLXDAT return 0 (no collisions) 742: transdisk and transrom patches from Rodney Hester. Don't warn about 743: 256K Kickstarts. Check diskfile sizes and try to determine whether it's 744: a normal or a HD diskfile. No HD drive identification yet (is it 745: different?) 746: 961013 Corrected lots of bugs in the return address stack. Fix some errors in 747: the compiler memory management. Use the "locked" flag for hash entries 748: differently, and don't enforce it on a cache flush. Compile JMP to a 749: constant address. 750: 961012 Remove regs from cache before sign extending them for ADDA, MOVEA and 751: similar things. Compile NOPs to nothing. Implement variable shifts/ 752: rotates. Most shifts clear the V flag: Handle this in the compiler by 753: some extra magic sequences after shifts or in the CC_AFTER_RO case in 754: flush_cc_cache(). 755: Implement a stack containing return addresses and their hash entries, 756: and compile JSR (to constant addresses)/BSR/RTS instructions inline. 757: 961011 compiler.c: Several bugs introduced in the last two days fixed. 758: New function compile_note_modify() which is used when an ea is 759: modified. This replaces calls to storeea with eaino_s == eaino_d. 760: Bah, the 386 doesn't set flags on a NOT. Use CC_TEST_REG again. 761: Do flag life analysis until no more changes are found. 762: Make sure all "data" parts of EAs are locked exclusively (esp. for 763: LEA, PEA) 764: 961010 compiler.c: Finish yesterdays changes. Get rid of reg/offset 765: bookkeeping in m68k_compile_block(), keep the information in struct 766: ea_info instead. Rewrite all instructions to use the new fetch and 767: store routines. 768: Don't force a byteorder conversion in sync_reg() if the reg doesn't need 769: to be written back. Don't do a SAHF or equivalent in compile_condbranch 770: if we are doing a BRA or BF. 771: Don't use CC_TEST_REG for NEG and NOT (this was inefficient for NOT and 772: wrong for NEG). 773: 961009 compiler.c: Two types of locks for registers; shared and exclusive. 774: Implement better EA fetching and storing routines. For pdi addressing 775: modes, lock the necessary registers shared before calling prepareea. 776: Unlock those registers again in generate_possible_exit(). 777: 961008 MOVEM instructions in the compiler to an absolute address could have 778: caused random memory corruption. 779: 961007 Spanish keyboard support for X by Ruben Martinez. Some configure fixes 780: (don't assume current dir is in path, don't assume ncurses.h exists if 781: libncurses does). 782: If we're calling 68k code from an emulator function, don't use compiled 783: code. 784: Add a compilation option USER_PROGRAMS_BEHAVE (for compiler). Make 785: compiler hash table larger. 786: 961004 Fix typo in configure.in. 787: Modify the compiler so it doesn't ever throw away code, unless it's 788: necessary for a cache flush. 789: Didn't quite squash the compiler flag bug yesterday. Try again. 790: In filesys.c, do_find(), add a parameter fallback that indicates that 791: the open should be retried with O_RDONLY if it failed with O_RDWR. 792: Use this in find_input(). This fixes problems with r/o files on r/w 793: volumes. 794: 961003 Play around with the x86 specific memory access functions. Problem: 795: __attribute__((regparam)) isn't reliable, and it seems that that's a 796: rather hard to fix bug in GCC. Add some alternatives to 797: md-i386-linux/memory.h; these aren't used yet though. 798: Huh, the compiler was completely wrong about the flag needs of 799: conditional instructions. I wonder how it could work at all... 800: Remove a and d arrays from struct regstruct; replace with array regs 801: with 16 elements. This allows better code for get_disp_ea() 802: 961002 BeBox diffs from Christian Bauer. Move all code from main() to new 803: function real_main(). 804: 961001 Use do_get_mem_*() functions for nextiword(), nextilong() and new 805: function nextibyte(). 806: 960930 genblitter optimizations: Don't generate expressions in genblitter, use 807: a second program called gengenblitter to generate a table of 808: expressions for genblitter to use. gengenblitter knows about a lot of 809: rules to simplify expressions. Some other tweaks to make GCC output 810: better assembly for blitfunc.c. 811: 960927 Turn off LED() in xwin.c (may fix SunOS joystick emulation problems) 812: Call XFlush() and XSync() when exiting. 813: Add some DOS patches. 814: Add hooks in filesys.c to support filesystem units in a GUI. Use them 815: in tui.c. Bugfixes in svgancui.c. Change the way tui_refresh() works. 816: New option "-A". 817: 960925 For read-only filesystems (CD...), use O_RDONLY in action_find_input. 818: 960923 Save options file even if rename fails. 819: Mirror address space every 16MB like we used to (got turned off by 820: accident). 821: Move some checks out of options.h into configure. Set up md-* 822: directories with machine-dependent stuff in them; configure creates 823: a link called machdep to the appropriate one. 824: 960918 Solaris sound update from Manfred Thole. 825: 960917 Add a timer.device replacement (buggy). 826: 960916 Tristan Cavelier's french keyboard patch. 827: Apply ReadTheSpecsBeforeYouWrite(tm) technology to AddPort(). 828: Implement RemPort(), GetCC(). 829: 960915 Tighten up some of the return values in Exec. 830: 960914 EXEC: Implement RemTask(), ObtainSemaphoreList() and 831: ReleaseSemaphoreList(). Set up more fields of the ExecBase properly 832: and Enqueue it in the library list. Make InitResident call AddLibrary 833: when appropriate (otherwise, intuition is never put into the library 834: list). Fix major braino in Obtain/ReleaseSemaphore() (tried to Enqueue 835: tasks into two lists). Make OpenLibrary() honor the version parameter. 836: 960913 EXEC: Idle task now runs in user mode (abuse 0xFF0D as second STOP 837: instruction). Make EXEC_IntTrap perform the RTE before trying to 838: schedule. 839: 960912 Solaris sound didn't compile. So much for making blind changes without 840: being able to test them. 841: 960911 As soon as you compile it under Solaris, it bombs... Now check that the 842: hardfile exists before determining the size in main.c. 843: execlib fixes: Set master DMA enable bit at startup, fix interrupt 844: code to survive an interrupt that occurs before the proper SetIntVector 845: call. Implement RawDoFmt(), CloseDevice(), CloseLibrary(), 846: FindResident(). 1.1 root 847: 960905 Lower 8 bits of POTGOR should be 0. 848: 960904 Implement MULU, MULS, ADDX and SUBX in compiler. 849: 960903 ncurses interface works. DOS people: please use the new portable tui.c 850: and turn dos-ui.c into a frontend for conio.h, similar to svgancui.c 851: In xui.c, unlink the temporary files ASAP. 852: Two new command-line options, "-o" and "-G". 853: Get rid of sz_unknown. 854: compiler.h, compiler.c: New files. 855: filesys.c, action_read(): Added a hack to test whether the first four 856: bytes read from a file a file contain 0x000003F3 (HUNK_HEADER), in 857: which case there's probably a LoadSeg() call going on and we ought to 858: flush the cache. Also, use the fact that memory is now linear. 859: 960902 Struggle a bit with dos-ui.c, rename it to tui.c (text-based ui), add 860: new file svgancui.c (ncurses ui) and try to make these two understand 861: each other. 862: 960829 New transdisk from Stefan Ropke (can write images) 863: Apply Patrick Hanevolds BeBox patches. 864: 96082x many changes to Exec. Still not booting (DMACON seems not to be set up 865: properly, and sometimes Signal is called with task==0). 866: 960821 Solaris sound from Manfred Thole. 867: 960820 In filesys.c, get_fileinfo(), return volume name for top-level 868: directory. 869: 960819 Reimplement WritePixel(). Layer locking is still missing. 870: 960818 Reverse meaning of -x flag for X11. More Exec code. 871: Several changes to the main CPU loop and the way call traps work. 872: 960817 Implement some simple Exec functions (Lists, AllocMem & friends) 873: 960816 filesys.c fixes from David Varley. 874: 960815 Implement graphics library region functions. 875: 960814 Modify memory layout: All memory is linear now; get_real_address() 876: returns a (UBYTE *). 877: 960810 Add Gustavo's latest DOS code. 878: In configure, include <sys/param.h> earlier for the sake of some *BSD. 879: Add three options for sound code (bits, frequency, buffer size). 880: Make -S option take a parameter; remove SPEED_UP_SIDMON_MODULES. 881: New version of transrom (return 0, duh). 882: 960805 Fixed the blitter line mode emulation (this time, really! I hope.) 883: Thanks to Fabio Ciucci for a detailed description of the correct 884: behaviour. 885: 960730 Spent the last three days trying to make the filesystem emulation 886: bootable by adding an expansion device for it. A fair bit of trial and 887: error, but now it works! Even the hardfile now works with Kick 1.3, but 888: you have to mount it manually after booting. 889: hardfile.c, filesys.c, expansion.c and autoconf.c now are an 890: entangled mess which badly needs to be cleaned up. 891: We can now mount more than one filesystem even with Kick 1.3: we 892: recognize them by param 2 of the startup packet, which has the same 893: value as the dn_Startup field of the devicenode. 894: Make Kickstart replacement work again (didn't like the CPU emulator 895: changes) 896: Include preliminary serial support from Stefan Reinauer. 897: 960728 Fixed the scancodes for <> and #' keys in svga.c 898: Apparently, CIA timer latches ought to be 0xFFFF after a reset 899: (prevents Eagleplayer from crashing occasionally). #ifdeffed out a 1.1.1.2 root 900: slightly weird call to INTREQ from RethinkICRB() 1.1 root 901: 960727 Sound code rewritten again. Now uses events (five new ones). All 902: modules seem to play correctly now. It's a bit slower, though. 903: AF sound should work again, patches from Marcus Sundberg. 904: 960723 ... and more CPU emulation bugs fixed by Herman. 905: Added uae.library from Tauno Taipaleenmaki, plus support files in the 906: "amiga" directory. 907: Added some files for the XFree86/OS2 port from Krister Bergman. 908: Reorganized all the directories. 909: 960717 Add latest patch from Herman. 910: More FAST_BLITTER options: 4 and 5. These finish the blit immediately. 911: 960713 Call XAutoRepeatXXX() only if we know we want to change the state. 912: 960709 Work around a few AIX bugs (ughhh... what a broken OS). New test for 913: sys/select.h. 914: In xui.c, don't try to communicate with a dead process. 915: 960704 More bugfixes from Herman. 916: Get rid of dummy_xlate(), use default_xlate() to abort with error. 917: In svga.c, set correct_aspect to 0 if using lores. 918: Change the Bcc exception 3 handling code a bit. 919: Add new program "cpuopti" that takes gcc-generated assembly files and 920: optimizes away unnecessary pushl/popl instructions on the x86. 921: 960701 68020 exception handling & various bugfixes from Herman ten Brugge. 922: In ersatz.c, use 0xFF0D instead of 0xF00D as trap opcode. 923: Do MMU "emulation" (no-op MMU instructions, probably many cases decoded 924: incorrectly). 925: 960627 New file LIESMICH, with minimal German instructions. Somebody want to 926: translate the docs to French, Spanish, Italian, all the Scandinavian 927: languages, Hebrew, Polish, Dutch, Russian, Welsh, Gaelic and something 928: [email protected] understands? (No offense meant - I'm sure there are 929: brillant minds using AOL. There must be.) 930: 960626 In zfile.c, make sure we delete the temporary file even if file 931: decompression fails. 932: Reimplemented sound support, this time following the HRM closely. Seems 933: to work fine most of the time, but occasionally loses drum beats in 934: TFMX modules. do_sound() is now unconditional, it calls 935: flush_sound_buffer(), which is system-dependent. This breaks everything 936: except Linux sound for now :( 937: Add Herman ten Brugge's 68020/68881 emulation code. 938: FreeBSD chokes if sys/mount.h is included without sys/types.h. Fix the 939: configure script. 940: 960622 More work on AGA code. 941: Removed 2-bit display routines from custom.c. Ian: please use dithering 942: code. 943: Make slowmem and chipmem sizes run-time configurable. 944: Mask out the high bits in BLT?PTH(). 945: Add exception 3 checks to Bcc/BSR instructions. Seems to be not quite 946: correct yet. 947: Completely rewrote the disk emulation. We now create a big track buffer 948: full of MFM data, used in a cyclic fashion by DSKBYTR() and friends. 949: The current position in the buffer is determined by the cycle counter. 950: DMA reads are now done in one piece. Two new event types: ev_diskblk 951: and ev_diskindex. 952: ARRGGHH! The RSI demo has _completely_ broken disk loading routines. 953: They start disk DMA on a block while the blitter is still working on 954: the same memory region. 955: In zfile.c, unlink() the temporary file directly after opening it so 956: it will be freed by the OS as soon as we close it (or crash... :) 957: 960621 Merge pfield_sprite_h() and pfield_sprite_l() into one function. 958: Split off new files blitter.c and blitter.h from custom.c. 959: Fixed null-pointer dereference in zfile.c when filename has no 960: extension. 961: Add new field maxline to gfxvidinfo that prevents writing past the 962: screen buffer if it has less lines than expected. 963: Modify the 256 color allocation routine to set nb_cols to the same 964: value first for r,g and b; allocate everything as usual and fill the 965: lost colors afterwards with those that have the greatest difference. 966: 960620 For some extremely weird reason, it is faster to simply call the 967: assembly-optimized pfield_linetoscr_full routines _twice_ to double the 968: line than calling the new (also assembly-optimized) 969: pfield_linetoscr_full_double routines, at least when writing directly 970: into the framebuffer. If someone has a good theory why, let me know 971: about it. 972: Drawing into memory is faster with the _double routines, but not 973: noticeably (about 1%). 974: Consequence: Removed the new pfield_linetoscr_full_double assembly 975: routines again. 976: Add a "--disable-gui" option to configure. 977: Add Samuel Devulder's dithering code. Provide support for mono and 978: 16 color X servers. 979: Put an assembly version of DitherLine() in X86.S. 980: New color mode (3) available, tells UAE to use 256 colors and dither 981: the image. This is meant for people who have only a 256 color X server 982: available, but it works with the SVGA version, too. It's much slower 983: than normal 256 color mode, though. 984: Use the color allocation algorithm from the dither code in 985: alloc_colors256(), too. 986: 960619 New files: zfile.c and zfile.h, from Samuel Devulder. These provide 987: transparent decompression of various compressed file formats. Enabled 988: by configure only for Unix systems. 989: Eliminate dont_want_aspect. New option "-C", sets correct_aspect. Make 990: video mode 3 640x480, video mode 4 800x600. Honor correct_aspect in 991: 320x400, 640x480 and 800x600 mode with SVGAlib. 992: Add fields maxlinetoscr and x_adjust to gfxvidinfo. 993: Rename pfield_slow_linetoscr() to pfield_do_linetoscr(). Use new fields 994: in gfxvidinfo to enable writing directly to the framebuffer in 995: resolutions with <800 horizontal pixels. 996: New function pfield_do_linetoscr_full(), called when sure that full 997: line update is being done. 998: Move some of the usage() information into some target_specific_usage() 999: functions, defined in the various system-specific files. 1000: Support lower resolutions with LOW_BANDWIDTH, too. 1001: memcpy() within screen memory is dog slow. Prevent some common cases: 1002: 1. Use fill_line() to double a line in the border. 1003: 2. Add a parameter to pfield_do_linetoscr_full() to indicate whether 1004: the line has to be doubled. New functions 1005: pfield_linetoscr_*_double_slow() that simply do a memcpy(), plus 1006: optimized ones in X86.S that are much faster by avoiding the copy. 1007: Smart update code could get confused by lores modes when 1008: prev_max_diwstop changed from one frame to the next. New variable 1009: frame_redraw_necessary, which acts as a counter. It's initialized to 1010: 2 in interlace mode to handle that case properly, too. 1011: Move sprite priority checks into pfield_sprite_?(), move HAM 1012: calculations into new function decode_ham6() to simplify the various 1013: linetoscr functions. 1014: Fixed a bug that would cause sprites to get deformed in some cases 1015: when they overlapped (never seen it). 1016: 960618 New file: dos-snd.c, from Gustavo. 1017: 1018: 960617 Release 0.6.0 1019: 960617 Fix memory clobber in X86.S when diwfirstword==0. Eliminate double test 1020: for HAVE_SYS_MOUNT_H in sysdeps.h. 1021: 960616 Handle programs that don't wait for the blitter by finishing a pending 1022: blit as soon as a blitter register is written to (regardless of DMACON, 1023: to be safe). 1024: Call gui_led only if the LED changed. 1025: 960615 Fixed dual playfield sprite priorities. Optimized dual playfield code 1026: in X86.S. More work on AGA code. Get joystick status only in 1027: vsync_handler to speed things up. 1028: Make blitter fill more intelligent with table lookups instead of loop. 1029: 960614 DOS update from Gustavo. Pass real bitplane pointer to 1030: bpl_data_differs(), don't calculate it again. 1031: 960610 Fixed silly INTEL_FLAG_OPT bug: The new __asm__ expressions use 1032: regflags, which is of course _regflags on a.out... 1033: More BeBox fixes from Christian. 1034: Make the CIA bank bigger (A0..BF) and relax the CIA A/B selection 1035: checks to make broken software (Kingsoft's Emerald Mine, reportedly) 1036: happy. 1037: Default framerate is now 1. 1038: 960603 New BeBox code from Christian. Fix test for ELF in configure.in. 1039: 960529 genblitter.c: generate blitfunc as a function taking ULONGs and 1040: returning an ULONG. This makes custom.o about 4500 bytes smaller on the 1041: x86 by removing worthless size prefixes, and should increase 1042: performance (better for the cache, and the P6 reportedly doesn't like 1043: 16 bit instructions anyway). 1044: memory.c: Load Kickstart in one block and swap bytes after that if 1045: necessary (eliminates the need for the special bebox load routine) 1046: custom.c: Some preliminary work for AGA support. 1047: 960528 Saw a real awful piece of code that detects the right mouse button by 1048: reading a value from POT0DAT, counting up to 25, reading from POT0DAT 1049: again, and deciding the button is pressed if the value changed. Urgl! 1050: Added POT0DAT() in custom.c ... 1051: Gustavo's latest patches. 1052: 960525 Do index pulse handling in CIA_hsync_handler(). Make sure bit 12 in 1053: INTREQ gets set on an index pulse. Don't call DISK_Index() for now, 1054: since this breaks the Workbench. 1055: The CIA code should _probably_ not be resetting the bits in INTREQ. 1056: Disable this as an experiment, let's see what breaks. 1057: 960524 Z flag handling for ABCD/SBCD/ADDX/SUBX was wrong (must be clear if not 1058: zero, was set if zero). Some other flag bugs in these functions fixed. 1059: 960523 gfxlib.c update from Christian Schmitt. Some new Mac code from Ernesto, 1060: still not all of it, though. Italian keyboard from Alessandro Bissacco. 1061: 960522 Fix the CHK instruction. Implement middle mouse button. 1062: 960515 Fix some Nextstep problems in configure.in. 1063: 960513 New Makefile target "streifenfrei" to remove all output from configure. 1064: Use autoconf 2.7; 2.9 is buggy. 1065: 960512 Remove BIG_ALIGNMENT hack. Remove superfluous pfield_fetchdata() call 1066: in pfield_doline_slow_l() that resulted in garbage on the screen. 1067: Move blttbl array from custom.h to genblitter.c 1068: Use new lookup tables imm8_table and areg_byteinc in CPU emulation 1069: instead of ?: expressions. 1070: GCC appears to generate better code if the opcode is passed as ULONG to 1071: the CPU emulation functions instead of as UWORD. 1072: Modify some of the flag emulation __asm__ statements so that GCC uses 1073: less registers for them. 1074: 960510 Cast malloc() results to char *, for C++ compilers. 1075: 960509 Use test for GCC and __i386__ in options.h to decide whether to use 1076: intel flag optimization. 1077: Use test for wish4.0 to decide whether to use the GUI. 1078: 960507 New bebox.cpp from Christian. AF sound patches from Marcus Sundberg. 1079: 960505 Fix the configuration stuff so it works. Fix some bugs in gfxlib.c 1080: 960504 Use GNU autoconf scripts to generate Makefile and sysconfig.h. Add new 1081: files sysdeps.h that includes the right system header files. Remove 1082: amiga.h and Makefile. 1083: 960502 More Next code from Ian (new Uae.app directory, 2 bit drawing for 1084: custom.c). 1085: 960501 Allow the sound driver to set the frequency to a value that is slightly 1086: different from the requested one. 1087: 960430 Added AmigaOS port from Olaf Barthel. 1088: 960427 Fixed single playfield sprite priorities in X86.S. 1089: 960426 Added new NeXTwin.m from Ian. 1090: Turn off the blitter delay in line mode. 1091: Added a CPU optimization from Olivier Raoul: gencpu now reads a file 1092: "insncount" that can be generated by UAE during execution and generates 1093: specific functions for the most common opcodes. Not documented yet. 1094: 960414 Reimplemented the fast disk emulation in a more sane way. Also it's 1095: only done for reads now. (Plus, it no longer works :-/ Need to work 1096: some more on this). 1097: In blitter emulation, defer not only the setting of the bltfinish bit, 1098: but actually defer the whole blit for the number of cycles it will 1099: take. This makes programs the clear the screen while it is still being 1100: displayed look much better. 1101: Changed supervisor mode handling around a bit (was messy). 1102: New DOS code from Gustavo. 1103: 960412 Removed smart update method 2. Added Alessandro Bissacco's blitter 1104: optimization patch. 1105: Fixed some sprite problems: during hysnc, clear sprpos and sprctl, and 1106: don't do_sprites() in line 0. 1107: 960409 Be a little more intelligent about when to call pfield_linetoscr() from 1108: pfield_doline_slow(). It's only necessary if a color register changed. 1109: If it can be deferred to the end of the line, use the the _full 1110: variants. 1111: Some CIA TOD fixes. 1112: Better transdisk, accepts first/last track parameters. 1113: 960405 New function memcmpy(), inline assembler for the i386. Compares two 1114: memory blocks and copies them at the same time. Used in 1115: bpl_data_differs. 1116: 960404 French keyboard from Tristan Cavelier. Parallel port emulation from 1117: Stefan Reinauer. 1118: Turn bpl?pt and r_bpl?pt into arrays, simplify some code using them. 1119: 960401 Some parts of Ernesto's new Mac sources. 1120: 960331 filesys.c: Close filedescriptors in free_key(). get_path() sometimes 1121: read uninitialized bytes. 1122: Minor cleanups all over the place. 1123: unchain_mnn() leaves sibling intact, but clobbers next. customreset() 1124: didn't care about that and crashed. 1125: Use the __asm__("intel_flag_lookup") magic not only for DOS. 1126: Support 320x300 for X (without LOW_BANDWIDTH). 1127: Add new function fast_memcmp(), defined as memcmp if __i386__ is 1128: undefined, otherwise a slightly optimized inline assembly function. 1129: 960329 Some bug fixes in gencpu.c 1130: 960328 Stupid programs write odd playfield modulos into the hw registers... 1131: Eek! Sometimes, linedescr[] was indexed with a negative value... Add a 1132: vpos >= minfirstline check to pfield_may_need_update(). I really need 1133: to rewrite this in Oberon... 1134: Don't turn off SHM when LOW_BANDWIDTH is selected. 1135: Keep the nextpos and linepos variables from pfield_doline_slow_?() as 1136: globals and initialize them in pfield_may_need_udpate(). 1137: Modified alloc_colors256() some more. 1138: Try to make sprite DMA follow the Amiga DMA slots more closely by 1139: adding a currhp parameter to do_sprites() and calling it at the end 1140: of a scanline or in pfield_may_need_update(). 1141: 960327 Added Gustavo's latest DOS code, as far as possible. Modified X86.S to 1142: use a macro SYM() to create symbol names either with underscore or 1143: without. 1144: Fixed some very silly SVGAlib lores bugs. Move screen 8 pixels up in 1145: low resolution. 1146: Use diwstop instead of diwstart to caclulate the DIW for 320x200 modes. 1147: Reset it not only in calcdiw(), but also in init_frame(). 1148: Speed up 256 color allocation a little bit. 1149: 960326 New function flush_block() in xwin.c and svga.c. Called from 1150: do_flush_line() and (new function) do_flush_screen(). Modify struct 1151: vidbuf_description, new member maxblocklines that records the maximum 1152: number of scanlines that do_flush_line() should collect before calling 1153: flush_block(). If it is zero, then flush_line() is used as before. 1154: This makes the special case stuff for SHM unnecessary, so it's removed. 1155: Fixed a stupid bug in events code: Put ev_hsync in front of ev_copper, 1156: so that do_copper gets called with hpos == 0 instead of hpos == 227 at 1157: the beginning of the line. 1158: New function init_frame() that sets up some variables, called from 1159: customreset() and vsync_handler(). 1160: Move smart update code to pfield_doline() from pfield_doline_h() and 1161: ..._l(). Clean up these two with a macro DO_ONE_PLANE, removing 1162: duplicate code. 1163: Implement big blits and ECS chip ids. New configuration options 1164: ECS_AGNUS and ECS_DENISE. 1165: Implement MOVEP. 1166: 960325 Before calling pfield_may_need_update(), make sure the value that was 1167: written to a register actually differs from the previous one. 1168: New expansion code from Stefan Reinauer. 1169: Modify struct mem_notify_node to contain a pointer to a valid bit 1170: instead of the valid bit itself, so that the playfield code has to 1171: check only one flag to decide whether to draw the line (SU method 2) 1172: 960324 The chip_flags approach has several problems. A flag may cover an area 1173: in memory that spans two scanlines, or several scanlines may use the 1174: same area in memory. 1175: Provide two other, different methods for the smart update: 1176: 1. Save all the bitplane data for each line and compare the chipmem 1177: with the saved data to decide whether an update is necessary. 1178: 2. Use a chain of memory_notify_node structs instead of a single bit 1179: for flags. Each scanline owns a set of these structs and chains them 1180: into the right place, and the chipmem_?put routines walk the chains 1181: and set the modified bit for each element. 1182: Unfortunately, both methods are slower than the old one. Especially the 1183: first one has some advantages though: it speeds up programs that clear 1184: the screen each update and write the same contents back, and it 1185: can speed up double-buffering programs at full framerate, since it does 1186: not have to check whether the bitplane pointers have changed. 1187: Remember the first and last drawn line for each frame, and pass them to 1188: flush_screen. Use this in xwin.c for SHM. Modify SHM logic: if smart 1189: update is selected, call XShmPutImage() from flush_line() instead of 1190: from flush_screen(). But gather blocks of consecutive lines to avoid 1191: calling XShmPutImage() too often. 1192: 960323 "Smart update" method, based very loosely on Alessandro Bissacco's 1193: work, implemented: 1194: Add an array chip_flags that records any change made to specific words 1195: in chip memory. 1196: Move all the hardware registers relevant to playfield display into a 1197: new structure bplinfo. Remember the contents of this structure in 1198: struct line_description for every line on the screen. Avoid redrawing 1199: in pfield_doline if the screen memory has not been modified for the 1200: line to be drawn and if the information from the last frame matches 1201: that in the current frame. 1202: 960322 Duplicate all functions responsible for drawing (pfield_doline, 1203: pfield_doline_slow, pfield_sprite, pfield_*word_*res) and append _h 1204: or _l (ah, the golden C++ days, when we had templates... which never 1205: worked). Modify the *_l functions to support drawing in low resolution 1206: (i.e. 320x200). Change the options -d and -H to support selecting color 1207: mode and resolution, thereby getting rid of some SVGALIB_* options. 1208: Get rid of the old pfield_*word_*res functions. 1209: Collect information about the minimum diwstart value during the 1210: previous frame and use that in case 320x200 was selected to fit the 1211: image on the screen. 1212: Get rid of HAVE_JOYSTICK (breaks the "-J" option) 1213: 960321 Give up in op_illg() if opcode is 0x4e7b and the exception handler for 1214: it is NULL. In that case, it's a 68020 Kickstart. 1215: 960319 New Next code from Ian. SunOS target was still screwed (two CFLAGS). 1216: Turn -x option into a "hair cursor" option. Support multiple mounts, 1217: but warn if more than one is seen (still does not work with Kick 1.3). 1218: Integrated Samuel Devulder's new LOW_BANDWIDTH patch. 1219: 960318 Integrated the start of Markus Gietzen's gfx library replacement. 1220: Changed the interface between custom.c and the graphics code. There has 1221: to be a buffer holding the data of all the lines on the screen. For 1222: linear SVGAlib modes, this is the video memory. Eliminated -x option, 1223: prepare_line(), DrawPixel() and the X_?BIT_SCREEN options, replace with 1224: 3 versions of pfield_linetoscr for different datatypes. Implement 1225: proper handling of the borders above and below the DIW in custom.c 1226: instead of in flush_screen(). 1227: Move common code (color allocation) from all the graphics files to new 1228: file gfxutil.c. 1229: Swedish keyboard from Per Olofsson. 1230: 1231: 960315 Release 0.5.0 1232: 960315 Newest DOS port from Gustavo. New sgi-gcc target. 1233: 960314 Add -lXext to osf target. Use "rb" for fopen() in main.c 1234: 960310 Play a bit with the __asm__ constraints. Implement CHK. 1235: 960307 Fix some stupid Makefile errors. Call parse_cmdline() if no init file 1236: is found. 1237: First round of NextStep patches; new file NeXTwin.m 1238: Stupid bug in custom.c: The #define is called NO_FAST_DISK, not 1239: NO_FAST_FLOPPY. 1240: Fix one of the problems the Deform demo had with the blitter: The 1241: line texture wasn't rotated to the right position in blitter_init(). 1242: 960306 Use some black GCC __asm__ magic to calculate flags more quickly 1243: (config INTEL_FLAG_OPT) 1244: HAM was broken by pfield_linetoscr changes. Fixed. 1245: LOW_BANDWIDTH sometimes got confused when the display window changed. 1246: 960305 BCD instructions work well enough for Locomotive Basic on CPE. 1247: New function parse_cmdline_and_init_file() that reads ~/.uaerc or 1248: ./.uaerc and adds the options found in those files to those in argv[]. 1249: Patch from Denis Sablic to make disk image filenames runtime 1250: configurable. Extend it for the ROM filename. 1251: Remove some of the run-time configurable stuff from config.h. 1252: More X keysym fixes (I finally got a proper .Xmodmap ...) 1253: for SVGAlib: Delete key, and PgUp/PgDn as Amiga keys. 1254: The sound driver can now handle 22050 Hz and/or 8 bit samples. Both of 1255: these are the default with LINUX_SOUND_SLOW_MACHINE. 1256: Also use the SNDCTL_DSP_GETBLKSIZE ioctl and write the buffer when 1257: there is enough data. 1258: Abuse keybuf.c to provide a fake joystick emulation with the numeric 1259: pad (enable with -J) 1260: 960304 bebox.cpp from Christian. 1261: Rename pfield_linetoscr_full to pfield_linetoscr_full8. 1262: More x86 assembly: pfield_linetoscr_full16. 1263: 960303 SunOS target from Dirk Vangestel. Put some not-so-superfluous includes 1264: back in. Added the DOS specific patches to filesys.c. 1265: Started x86 assembly optimizations. New file X86.S, includes an 1266: optimized version of pfield_linetoscr (for 8 bit screens only). 1267: Don't use SA_RESTART if it isn't defined. 1268: prepare_line() wasn't called often enough (again...), leading to memory 1269: corruption and "hit the reset button" bugs when using SVGAlib. 1270: 960226 Get rid of bool, true and false in amiga.h and everywhere else. 1271: Copy yesterdays code to AF_SOUND code, too. 1272: Include first round of Christian Bauer's BeBox patches. Add AIX fix 1273: from Samuel Mackrill. 1274: Add #include <string.h> and #include <stdlib.h> in some more places. 1275: Modify gencpu.c and readcpu.c so that immediate types j and J (0..15 1276: and 1..8) can be merged. Replace HAVE_ONE_GIG... option with a new 1277: CPU_EMU_SIZE option that can be set to a value in the range 0..5, 1278: where 0 is minimum size and 5 is equivalent to HAVE_ONE_GIG... 1279: 960225 Remove multiplications in sound code, use a big lookup table. 1280: 960222 Go back to having only one memory bank table of type addrbank instead 1281: of several function pointer arrays. Eliminate the HAVE_BROKEN_SOFTWARE 1282: define by extending the memory bank table to 65536 entries. 1283: Remove remaining DUALCPU code. Allow BTST src,imm instructions in 1284: table68k. 1285: 960220 Back out filesys.c change from Stefan Reinauer: don't call V36 specific 1286: functions in expansion.library. 1287: Better fix for the filesys.c assign problems by Oliver Moehrke. 1288: Make new playfield code conditional on EXPERIMENTAL_SCREEN_UPDATE. 1289: Improve the 64bit variant of said code. Try to get alignment for 1290: apixels by putting it into a union with a long. 1291: Kill the child in gui_exit(). Make graphics_init() return a value and 1292: check it in main.c to see whether graphics were initialized. If not, 1293: call gui_exit() anyway. 1294: Use new 256 color allocation routine from svga.c in xwin.c, too. 1295: Make LOW_BANDWIDTH compile _and_ work (wow...). 1296: 960219 Fix bug in memory.c: When loading 256K Kickstart, copy 256K, not 128K. 1297: 960218 Finished the rest of the UI: reset, debug and quit buttons as well as 1298: drive LEDs. New target linux-gui; all others use dummy file nogui.c 1299: for now. 1300: 960217 The GUI now supports inserting and ejecting diskfiles and displays 1301: their names. Two pipes are used now, one for reading and one for 1302: writing. Properly wait for the process to start up. 1303: Use sigaction() instead of signal() in debug.c. 1304: More fixes for the new display routines: Need to do a final call to 1305: pfield_*word_*res with the data shifted right from the last fetched 1306: word. 1307: 960216 Copper & sprite bugfixes from Marco Nelissen. Better X keyboard support 1308: from Bruno Coste. 1309: Move my_strdup() from filesys.c to options.h 1310: New files xui.c, uae-ui (shell script) and uae-ui.tk (wish script). 1311: These create a GUI for the X version of the emulator. So far, the 1312: power LED works. 1313: 960215 Don't rely on SVGAlib headers defining any keycodes at all. 1314: Include Thorsten Frueauf's NetBSD patch. Apparently, the devname 1315: variable in hardfile.c caused a namespace collision, so rename it to 1316: uaedevname. Fastmem fixes, debugger help, and ConfigDev allocation in 1317: hardfile and filesys from Stefan Reinauer. 1318: xwin.c: Give the window a title. 1319: Half-implemented the DIVU.L, DIVS.L, MULU.L and MULS.L instructions. 1320: 960213 AF sound system support from Marcus Sundberg. Win95 keyboard support 1321: for SVGAlib from Thierry Lescot. Added most of Gustavo Goedert's MS-DOS 1322: port. 1323: When using the old pfield_*word_*res functions, the gen_pfield_tables() 1324: function was undefined. 1325: Hmmm, /dev/brain must have been unmounted when I wrote the new pfield_* 1326: functions. Now they make sure they access the apixels array only with 1327: addresses that are multiples of 16 bytes. 1328: 960212 Fix copy&paste bug in cia.c found by Marco Nelissen: Need to call 1329: RethinkICRB() instead of RethinkICRA() for CIA B timers. 1330: Added Stefan Reinauers autoconfig area/fastmem support. Added run-time 1331: options for use_slow_mem and use_fast_mem. 1332: Oops, the pfield_*word_*res() optimizations break completely on HPs and 1333: Sparcs. Now use this optimization only if we are using GCC 2.7. 1334: HPUX fixes in the Makefile. New target hpux-gcc. 1335: The code for clearing the areas above and below the DIW was trying to 1336: be a little too clever selecting the color. Just use the current 1337: background color. 1338: Added channel attachment to the sound code. Untested. 1339: 960211 Found some flag setting bugs in the rotate/shift instructions and in 1340: addx/subx (which I thought I had already fixed) by reimplementing 1341: DUALCPU mode to work with Ed's e68k. 1342: Argh! The copper is completely disabled during DDF in Hires 4 bitplane 1343: mode - so copper positions 0x30 and 0x34 are about 640 pixels apart. 1344: The Kickstart uses FF39FFFE to wait for the end of line 256 instead of 1345: FFDFFFFE as in all the other modes. This is implemented now, but 1346: probably not 100% correct. 1347: Added check whether SVGAlib doesn't support our mode. 1348: If using GCC >= 2.7, define __attribute__((aligned(16))) as 1349: BIG_ALIGNMENT in config.h. Use it for the apixels array to prevent 1350: potential problems on the Alpha. 1351: Tried to make the color selection routine produce better results in 256 1352: color mode. 1353: 960210 readdisk didn't work at all for large files - fixed. 1354: In pfield_doline(), clear the apixels array if playfield DMA is off. 1355: In SPRxCTL(), reset sprite mode when sprpos==sprctl==0 1356: Rewrite pfield_orword_hires() and friends to use lookup tables. No 1357: noticeable improvement on my machine, but might be different on other 1358: machines. Two versions of this code: one using 64bit longs on the Alpha. 1359: New targets linux-debug and linux-prof. 1360: Use 1MB slow mem. 1361: -funroll-loops is a little excessive. Remove it. 1362: Add support for linear addressing modes for SVGAlib version. Speedup 1363: is 20-30% on my old 486 VLB. Now, would someone please fix SVGAlib to 1364: support that for the S3-864 as well? 1365: Set SVGAlib keyboard mode to DONT_CATCH_CTRLC. 1366: Change custom.c, xwin.c and svga.c to keep track of the display window 1367: and background color and to clear the areas above and below the display 1368: window if necessary to remove garbage images from previous frames. 1369: Set the LOF bit in the Kickstart replacement init routine. Also 1370: initialize CIAs to Kick 1.3-like values. 1371: 960209 Some more -DHAVE_xxx_H options in the Makefile and filesys.c. DEC Alpha 1372: fixes for filesys.c from Ed and Marcus. HPUX fixes. 1373: New field in table68k for CPU type, parsed by readcpu and compared to 1374: CPU_LEVEL which is defined in config.h. New instructions MOVE2C, MOVEC2 1375: and CAS. Also a new field for priviledge level that is used by gencpu to 1376: generate tests for regs.s and Exception(8) calls if necessary. 1377: Move parsing of table68k into a new file build68k.c. Generate a file 1378: called cpudefs.c containing the information from table68k in 1379: machine-readable form. Change readcpu.c to use the array found in 1380: cpudefs.c. 1381: Don't generate the d8(An,Dn) addressing mode in-line. Generate a call to 1382: get_disp_ea(), which is an inline function in newcpu.h if UAE is 1383: configured for 68000 emulation; for 68020 emulation, it is defined in 1384: newcpu.c. 1385: Debugger could crash on illegals because there was no mnemonic defined 1386: in lookuptab[]. 1387: Return zero for SERDATR. 1388: 960207 It seems that the copper stops completely if an attempt to write to a 1389: specific register fails because of COPDANG. Apparently, the Kickstarts 1390: use this to stop the copper with a 0x00000000 longword. This leaves the 1391: question why they don't do 0xFFFFFFFE like everybody else. 1392: Enable 512K slow memory by default. 1393: Integrate Stefan Reinauers battclock patch that makes it work with 1394: newer Kickstarts. 1395: In cia.c, do the little index pulse hack even if dskdmaen==1, because 1396: DMA is only enabled when dskdmaen==2 (Helps the "Mad Decision" demo). 1397: Add solaris entry to Makefile (GCC, Openwin, -DHAVE_STATFS_H) 1398: Define HAVE_STRINGS_H for SGIs, change filesys.c accordingly. 1399: 960206 Build a smaller table instead of cputbl.c. Use readcpu and the smaller 1400: table to build the cpufunctbl array at run-time. 1401: Nuked the other half of the old CPU emulator. Reimplemented debugger to 1402: use the information generated by readcpu. 1403: Define HAVE_STATFS_H for SGIs in the Makefile, and use that as a test 1404: in filesys.c instead of #ifndef __linux. 1405: Hack filesys.c, get_path() to support the assign command. 1406: Add -fstrength-reduce and -funroll-loops in Makefile to make people 1407: nervous. 1408: Rewrite Sam Devulder's LOW_BANDWIDTH patch and add it to xwin.c. 1409: 960205 Forgot some PC-relative bit instructions in table68k. 1410: Nuked half of the old CPU emulator. 1411: Split gencpu.c into two parts, new one is called readcpu.c and just 1412: parses the table68k file. Link it to the main program. 1413: 1414: 960205 Release 0.4 1415: 960203 filesys.c, action_read(): Slightly more efficient code (translate Amiga 1416: address to real pointer). 1417: Moved some common code in the generate_* functions in gencpu.c to a 1418: separate function. 1419: 960202 Added an experimental fast disk option. Currently turned off by 1420: default (it's not such a big win). 1421: Attached sprite fixes (overlapping att. sprites looked bad, Katakis). 1422: Add sleep(1) before resetting the console to text mode when using 1423: SVGAlib: this might fix some screen corruption problems. 1424: Add sprite/playfield priority checking to the most important case 1425: (single playfield, no HAM). 1426: In filesys.c, do_find(): open() returns -1 on error, not zero. 1427: Return ERROR_OBJECT_WRONG_TYPE if do_find() is called for a directory 1428: (fixes Champions of Krynn harddisk installation). 1429: 960201 Don't abort if sound driver not present, just set produce_sound to 0. 1430: New files keybuf.c and keybuf.h to record keypresses in the right 1431: order and without losing any. In cia.c, force 15 scanlines between 1432: keypresses, just to be sure. 1433: unixfs.device _does_ work with Kick 1.3: just don't trust what Kick 1.3 1434: sends in the startup packet. For now, disable more than one mount per 1435: command line. 1436: Started integrating Ernesto's new Mac sources. 1437: Remove superfluous includes from some files. 1438: 960131 Added Ed's unixfs.device (great stuff). 1439: Adding ULONGs to pointers is a bad idea on the Alpha if the ULONG value 1440: really is signed. Add some casts to LONG in (pc_p + src) expressions 1441: in genpu.c. 1442: If DMACON is written and copper DMA is enabled, do a COPJMP1 at once. 1443: Helps the "Interference" demo. 1444: 960129 More SGI fixes from Ed. Bugfixes and transdisk improvements from Marcus 1445: Sundberg. 1446: Remove EXTRA_DEFINES from Makefile. Breaks some systems. 1447: Move common sprite code from pfield_doline() and pfield_doline_slow() 1448: to new function pfield_sprite(). The same sprite may appear more than 1449: once on the same line, so don't shift out the bits of sprdata[] and 1450: sprdatb[] while displaying it (Turrican I). 1451: In xwin.c and svga.c, barf if LINUX_SVGALIB doesn't match the file 1452: being compiled. 1453: Make all .o files depend on config.h in the Makefile. 1454: No need to exit if sound driver unavailable, but -S given. 1455: Small debugger fix: Missing space in output. 1456: Fix for the sprite logic: Specifically, use a state variable indicating 1457: whether the sprite has been restarted after a VSYNC. Fixes most 1458: Turrican problems. 1459: 960124 Added Denis Sablic's patch for sound run-time option. 1460: Added Ed Hanway's patch for better Makefile, X mouse cursor blanking 1461: and more SGI compilation fixes. 1462: 960123 Include options.h everywhere. 1463: Handle 8 bit GrayScale visuals like PseudoColor. 1464: Remove C++ leftovers from joystick code. 1465: 960122 When using the joystick driver, the button test must come after 1466: handle_events() in vsync_handler(). 1467: 960118 Removed all the remaining C++ comments. Changed all inline keywords to 1468: __inline__. Define __inline__ if not using gcc. 1469: Make proper prototypes for everything. Compile with maximum warnings + 1470: -ansi + -pedantic. 1471: Remove CIA_cycle(), obsolete. 1472: Reimplemented the STOP optimization in newcpu.c. Removed DualCPU 1473: support in CPU emulator. 1474: Real nasty bug in pfield_doline() fixed: sprxpos could be evaluated as 1475: negative, with not-so-amusing results. (Need to rewrite this in 1476: Oberon to get array bounds checking :-) 1477: 960117 Heroic effort: Rewrote the thing in C. This might help fix some 1478: problems with users being unable to compile it. 1479: Fixed a problem in hsync_handler(): Only call flush_line() for lines 1480: in the display window, i.e. when we did a prepare_line() before. 1481: Better code for relative branches: Don't use setpc(getpc()+x) calls, 1482: increment regs.pc_p instead. 1483: 960116 Reimplemented the function to load the Kickstart ROM. Use stdio instead 1484: of fstreams since this apparently does not work on the Mac. Detect 256K 1485: Kickstarts. Detect corrupt ROM images (calculate checksum). 1486: Added Ernesto Corvi's Mac port. Changed it around a bit, so it 1487: probably won't compile. 1488: 960115 Reinstate config.h options for X screen depth, so that DrawPixel() can 1489: be inlined in custom.cc for speed. xlinebuffer is now incremented in 1490: each call to DrawPixel() (for both X and SVGAlib) to get rid of some 1491: address calculations. 1492: 960114 Fixed X generic pixel drawing routine for SHM. 1493: Still trying to fix the harddisk emulation. 1494: uae.device no longer breaks the debugger (can step through uae.device 1495: functions now) 1496: Bugs affecting performance: SPCFLAG_STOP never got reset, and DSKLEN() 1497: would set SPCFLAG_DISK even if DMA was being turned off. 1498: Made slow memory a run-time option. 1499: Defer interrupts by one CPU instruction to give programs a chance to 1500: read INTREQR ("Seeing is Believing" and "Substance" demos) 1501: Added ScrollLock hack for X, too. 1502: 960113 SVGAlib version compiles again. Fixed SVGAlib mouse bug. 1503: Fixed SHM bug: Maximum scanline is 313, not 312. 1504: Sometimes, disk.cc missed a side change and would read the wrong data. 1505: Fixed. Apparently, this was the worst compatibility problem. 1506: Implemented trace mode. 1507: 960112 Changed layout of class amigamemory a little so that gcc can generate 1508: better addressing modes. 1509: Finally wrote functions in gencpu to generate MOVEMs. 1510: 960109 Integrated Ed Hanway's patches for better X support and run-time 1511: configuration of some options. 1512: Got rid of the direct VGA memory access. (Need to do this differently). 1513: Changed the method of drawing lines: custom.cc now tells the graphics 1514: code the line number and whether it needs to be doubleed before drawing 1515: it. 1516: Added Andre Beck's MIT-SHM patch. 1517: Remove warnings for newcpu.cc. 1518: 960108 Fixed exceptions in op_illg(): Need to decrement PC. 1519: 960107 Added an "uae.device" resident module at 0xF00000. This emulates a hard 1520: disk (fixed size 8MB for now). 1521: 960106 Moved some common code from pfield_doline() and pfield_doline_slow() to 1522: a separate function. This fixes a potential HAM bug (two static vars 1523: for the same value). 1524: Sound support for Linux. Works only with graphics off and the CPU 1525: slowed down. 1526: Better SVGAlib keyboard support. 1527: 960105 Added AvailMem(), AllocMem(), AllocAbs() and FreeMem() dummies. 1528: The Hardwired demo times the multiplication instructions and prints 1529: "This demo don't like Axel" if they are too fast. Apparently, Axel has 1530: a 68040. Added a WANT_SLOW_MULTIPLY option to config.h. 1531: Fixed the fast blitter emulation (seems to work now). 1532: 960104 Fixed all the ChangeLog entries from 95 that said 96 (oops??!) 1533: pfield_may_need_update() should check whether bitplane DMA is on. 1534: Added ersatz.cc and ersatz.h. The purpose of these files is to 1535: implement one or two Kickstart functions that are commonly called from 1536: bootblocks. This should help support some games and demos that only use 1537: the Kickstart as an initial track loader. So far, it's only good enough 1538: for one program. 1539: 951223 More intelligent event handling in the CPU emulator. Slightly faster. 1540: 951222 Optimize CPU emulation by inlining cctrue(). Also, the real PC no 1541: longer needs to be incremented each instruction. The real PC value 1542: now has to be fetched by m68k_getpc(). 1543: Added direct screen access for SVGAlib, but it didn't help much. I'll 1544: probably remove it again. 1545: The gencpu executable is 2M smaller if it allocates memory 1546: dynamically. 1547: 951216 custom_bput() enhanced a little. Now remembers the value that was 1548: written in the other half of the register. 1549: Apparently, the USEx bits of BLTCON0 are ignored in line draw mode. 1550: (Silents-Demo) 1551: 1552: 951212 Release 0.3 1553: 951212 Included Alessandro's battclock patch. 1554: Fixed mouse autocalibration for wrong-aspect screens. 1555: 951210 Joystick support for Linux. 1556: Better color matching for 256 color modes. 1557: Rewrote most of the memory management in plain C, mainly to avoid the 1558: various template bugs in some compilers, but also because gcc can't 1559: handle the regparm attribute for virtual functions yet. 1560: 951209 Added Alessandro's patches for automatic mouse calibration. 1561: Tried to optimize the blitter loop a bit. Doesn't work. 1562: 951205 Added Hannu's patches for diskfile write support. 1563: 951201 More portability fixes, especially for weird compilers that workstation 1564: vendors ship. 1565: 951125 More keys for X, some keyboard support for SVGAlib (slightly 1566: dangerous); beginnings of US keyboard support. 1567: 951124 256 color mode support for SVGAlib. FAST! 1568: 951123 Tiny tweak to central loops in playfield code results in much better 1569: assembly. Apparently, GCC does not feel too good about optimizing 1570: reference variables. 1571: 951113 Bug fix in the events code (nextevent must not be changed while events 1572: are being processed). 1573: 951112 The playfield can now be drawn with the right aspect (i.e., every line 1574: twice). Slower, but looks nicer and supports interlaced mode 1575: (flickerfree!). The first 29 lines (blanking interval) are omitted 1576: now to fit everything in 800x600. 1577: Oops, disk drive identification did not work. Fixed, all four drives 1578: appear now. 1579: Oops, CIA_reset() was there all the time but never got called. 1580: Optimized the planar->chunky conversion in pfield_doline() a little. 1581: This really is time critical. 1582: 951111 If colors change on a line, we might still be able to use the full 1583: line update, if the change occurred outside the DIW. Have to be a 1584: little careful, though. 1585: Playfield code now uses real pointers again, but makes sure it can 1586: read enough bytes to complete the current line without segfaulting. 1587: Oops, my "better estimate" (see below) was a mistake. Restored the 1588: original 4 hw cycles per instruction relation. This slows down the 1589: emulator while booting (more screen refreshs), but speeds up many 1590: demos that otherwise spend most of their time waiting for a specific 1591: raster position. 1592: Playfield modulos must be added immediately when DDF stops. (WOC demo) 1593: Portability fixes in disk.cc (null pointers). 1594: Implemented average frame rate calculation ('c' in the debugger). 1595: Debugger fixes. 1596: Sprite fixes (height was wrong, wrong priorities in fast update) 1597: Added an AutoConfig expansion RAM device. The OS seems to recognize 1598: it, but breaks sometime later (seems to be the same bug that kills 1599: the emulator when there's RAM at 0xC00000). 1600: SVGAlib now has mouse support, too. 1601: HAM mode implemented. 1602: 951110 Implemented fast complete line playfield update. Switches back if 1603: necessary. Fixed attached sprites bug. 1604: Copper wait no longer slows down the CPU emulation. (there were 1605: lots of new copper bugs because of this, but I hope I fixed all 1606: of them). 1607: Changed cia?t? from UWORD to ULONG, since there were overflows in 1608: the assertion (because of 65535+1 == 0). 1609: 951108 The DIVS remainder could have the wrong sign. 1610: New HAVE_BROKEN_SOFTWARE define in config.h that makes the emulator 1611: mask out the high byte of all addresses. 1612: Wrote genblitter.cc and replaced the awful code in blitter_blit() 1613: and blitter_line() with calls to the generated function. 1614: 951107 Implemented ?BCD. These don't really work yet. 1615: 1616: 951106 Release 0.2 1617: 951105 Fixed a bug in the new CIA timer code. 1618: Fixed flag settings for some cases of ADDX/SUBX 1619: 951104 Changed the main loop a bit - call all the *cycle() functions only if 1620: it is really necessary. I hope everything still works - at least it is 1621: twice as fast now :-D 1622: Improved mouse emulation - avoid overflows, permit "wraparound". 1623: Added debugger 'g' command. 1624: Removed some useless casts from the CPU emulator. 1625: Added a configuration option to prevent checks for odd addresses. Only 1626: very bad programs need this check. 1627: 951103 The sprite emulation sometimes did not work too well, especially with 1628: dual playfield mode. Hopefully fixed. 1629: 951102 The 10 cycle counter is more like a 5 cycle counter in this 1630: implementation. (Fine, that makes floppy loading even faster :-) 1631: Implemented mouse movement. Totally out of sync with the X pointer, 1632: but at least something. 1633: Found out about the XAutoRepeatOff() function. Real useful. 1634: DualCPU mode works again. 1635: Corrected flag settings for CMPA.W. 1636: Fixed DIV instructions: Don't change dest in case of overflow. 1637: 951031 The PC is now converted to a real pointer. This is safe (much safer 1638: than converting bitplane pointers, since the PC always has to be valid) 1639: and should speed things up a little. 1640: 951029 Some primitive event handling: 2 mouse buttons and 1 joystick button 1641: are emulated, as well as parts of the keyboard (only german mapping). 1642: Fixes: Delay values and sprite widths are always LoRes. Playfield 2 1643: uses colors 9..15. 1644: Implemented a frame rate configuration option that can speed up the 1645: emulation quite a bit. 1646: 951028 A-ha. The 68000 has one strange feature after all. MOVEM.W to Dn sign 1647: extends the value to a longword. 1648: Katakis expects that accessing odd addresses causes exception 3, so 1649: we have to emulate this. *Sigh* 1650: Do at least something with the index pulse bit. It's more or less a 1651: toggle now. 1652: Implemented sprites & dual playfields, both with small glitches. 1653: 951027 When LOF is set, the frame is one line longer. 1654: 951026 Implemented a preliminary diskfile type for special formats. Turrican 1655: boots up correctly (crashes if I want to play a game, though). 1656: Implemented EHB and added a few missing masking operations in the color 1657: handling. 1658: Fixed the absw addressing mode - need to sign extend here as well. 1659: 951025 Fixed another extremely stupid bug, this time in the playfield code. 1660: Each pixel was calculated four times... 1661: Increased the size of the apixels array - this was being overrun. 1662: 951024 Fixed an extremely stupid bug in flag settings for byte and word 1663: operations. 1664: The "sectors until gap" field must be in the range 1..11 instead of 1665: 0..10, or very bad things will happen if it is used to calculate a 1666: blit size. 1667: 951021 Don't use real pointers to fetch bitplane data - too many segfaults. 1668: Delay the copper after executing an instruction, or wait sequences like 1669: FFDF FFFE 0200 FFFE won't work. 1670: Some programs expect that the CPU is completely turned off if the 1671: blitter nasty bit is set. So be it. 1672: The RSI Megademo chokes when disk DMA fetches two syncs. Leave one out. 1673: The LOF bit wasn't set correctly. 1674: 951020 Blitter fixes: Load fill carry from FCI each line; keep the masked 1675: value of bltadat in bltolda 1676: Give the CPU twice as many "cycles" - this still is not even remotely 1677: correct, but a better estimate. 1678: 951017 Added SVGAlib support. Unfortunately, my graphics card isn't fully 1679: supported by the current SVGAlib version. 1680: 951015 More small optimizations to memory.h and custom.cc. 1681: Added code for 256 color screens. The type of screen has to be 1682: selected at compile time. 1683: 951014 Modified the memory management to be (hopefully) a little more 1684: efficient. 1685: Changed gencpu.cc to generate functions and a big function pointer 1686: array instead of the old case labels. The generated C++ files now 1687: compile a lot faster, and the code should be better as well. 1688: 951013 Implemented pseudo POTGOR to keep the RMB from being detected as 1689: pressed all the time. 1690: GenerateDecTab() generated TRAP incorrectly. 1691: Made some more instructions (MOVE.B A0,D0 etc) illegal in gencpu.cc. 1692: Fixed X colors. Fixed data fetching for HiRes screens. 1693: 951011 EXT.WL instructions set the flags. 1694: Implemented second CPU emulator, plus "DualCPU" option. The new CPU 1695: emulator is generated automatically from a file called table68k by 1696: a program called gencpu. 1697: 951002 Removed version information from the file headers. 1698: Removed some sillinesses in custom.cc. 1699: DSKLEN bug fixed (mask out 0xC000). 1700: Playfield code rewritten. Now supports horizontal scrolling. Implemented 1701: some primitive color support. 1702: 950927 Fixed predecrement/postincrement addressing with byte size for the 1703: stack pointer. 1704: 950926 Fixes to the disk code: Terminate disk DMA, flip disk side, read more 1705: than just two sectors during disk DMA, fix checksum calculation. 1706: Fixed copper comparison bugs. 1707: 1708: 950901 Release 0.1 1709: 950826 bugfix in GenerateDecTab(): LEA.W instructions were generated. 1710: 950312 New file disk.cc, for (guess what) disk support. Doesn't work yet. 1711: 950311 Multiplication instructions were generating 16 bit results. 1712: Sign extension was wrong in some places. 1713: Removed bugs in the blitter (one word width: ALWM & AFWM and line mode) 1714: The Kickstart logo looks perfect now. 1715: Playfield routine should check BPLCON0 instead of BLTCON0 1716: 950309 ASR D8,D0 is not a valid instruction. 1717: Bitplane pointers were not incremented. 1718: Copper comparison didn't work. COP2LC and bitplane pointers were written 1719: incorrectly. Fixed. 1720: Something that bears a striking resemblance to the familiar Kickstart 1721: logo now appears in my X window! 1722: 950306 ROR used to set the X flag. Bug fixes in GenerateDecTab. 1723: More bug fixes in several 68000 instructions. 1724: Improved blitter. ?????? KS1.3 doesn't seem to set BLTDMOD on a 1725: line draw. What is this?? 1726: Fixed stupid bugs in playfield code. 1727: 950305 fixed bugs in opcode generation and interrupt handling. Implemented 1728: STOP. Fixed flag settings: Result wasn't masked. Ooops!! 1729: ADDQ #imm,An doesn't set flags. 1730: One-shot timer mode didn't work. 1731: Implemented blitter, doesn't work. 1732: Some primitive and slow playfield support, only to make the things that 1733: hopefully will soon appear visible. 1734: 950304 CIA timers ought to work OK. Copper is emulated. 1735: Emulator loops infinitely when trying to initialize the console.device 1736: 950303 experiments with X, figured out how to open a window and draw pixels. 1737: No graphics emulation yet, though. 1738: 950301 Nearly all instructions work. 1739: Fixed supervisor mode stack. 1740: The memory manager now handles CIA chips. 1741: 950228 Bug fixes in 68000 code, exceptions and more instructions implemented 1742: Memory management extended to handle custom chips as well. 1743: Debugger improved. 1744: Kickstart passes memory & CPU type test, builds up some system 1745: structures. 1746: 950227 MC68000 & little debugger for tracing. It can execute the first couple 1747: of KS1.3 instructions, but doesn't get past the memory test. 1748: 950225 Work begun
