Revision: 1.76
Committed: 2001-07-09T11:21:58Z (22 years, 9 months ago) by cebix
Branch: MAIN
Changes since 1.75: +6 -1 lines
Log Message: 
- ADB has its own interrupt flag, INTFLAG_ADB
- ADBMouseMoved(), ADBMouseDown/Up() and ADBKeyDown/Up() trigger the ADB
  interrupt
- ADB mutex is only used for mouse movement (the only input state where it
  matters)
- adb.cpp: toggling relative mouse mode resets mouse_x/y
- PrimeTime(0) schedules a timer task with 0 delay time; this is still not
  the correct implementation, but it makes MacSyndicate work...
- Unix: pthreads are preferred to POSIX.4 timers for 60Hz ticks because the
  timers drift badly under Linux and the thread can compensate for drifting
  well enough
- Unix: moved GetTicks_usec() and Delay_usec() to timer_unix.cpp
- video_x.cpp: X mouse acceleration is disabled in relative mouse mode because
  MacOS does its own acceleration
- video_x.cpp: palette[].pixel and palette[].flags are always preset
- video_x.cpp: decoupled X event handling from 60Hz video refresh cycle by
  using select() with a timeout on the X fd

# User Rev Content
1 cebix 1.68 V1.0 (snapshot) - <date>
2 cebix 1.71 - added support for on-the-fly video resolution and depth switching,
3     and gamma tables
4 cebix 1.70 - fsave/frestore emulation under AmigaOS and NetBSD/m68k always behaves
5 cebix 1.68 like a 68882/68040 FPU, eliminating the need for 68060 FPU patches
6 cebix 1.73 - added support for platform-independant mutexes, used by adb.cpp for
7     thread-safe mouse handling
8 cebix 1.75 - the TIME_OFFSET constant has been replaced by a (portable) function
9     TimeToMacTime(); file dates in ExtFS should now be correct
10 cebix 1.76 - ADBInterrupt() is no longer called from the 60Hz interrupt but has
11     its own interrupt flag, potentially increasing the smoothness of
12     mouse movement
13 cebix 1.72 - Unix: windowed display mode supports different resolutions and color
14 cebix 1.76 depths, which can be switched on-the-fly
15 cebix 1.73 - Unix: Ctrl-F5 grabs mouse in windowed mode (enhanced compatibility
16     with games like flight simulators)
17 cebix 1.76 - Unix: X11 events are handled as soon as they arrive, outside of the
18     60Hz video refresh raster

70 cebix 1.45 - AmigaOS/Unix: it's possible to specify preferences items on the
71     command line
72 cebix 1.48 - BeOS: implemented the "powerrom_cpu" CPU engine for BeOS/PPC that
73     uses the 680x0 emulator contained in an Apple PowerMac ROM to run
74     Basilisk II (ca. 4x speed improvement); when running on a BeBox,
75     a PCI PowerMac ROM image is needed to use this (the path name of the
76     ROM file can be set with the preferences item "powerrom", default
77     is "PowerROM")
78 cebix 1.35 - include/macos_util.h: defines FOURCC() macro to make MacOS-like

90     support
91     - Unix: "--without-mon" configure option now works
92     - Unix/video_x.cpp: DGA and SHM are only tried on local X11 displays
93     - Unix/video_x.cpp: re-integrated old window update method; frameskip=0
94     ("Dynamic") selects new method, other values select old method
95     - Unix/prefs_editor_unix.cpp: new "Input" pane, containing keycode
96     and mouse wheel options
97 cebix 1.31 - AmigaOS: added support for CyberGraphX [Jürgen Lachmann]
98 cebix 1.30 - audio.cpp: audio_data is cleared on reset [Lauri Pesonen]

116     and Mac2Mac_memcpy
117     - extfs.cpp: fixed bug in fs_rename() and fs_cat_move() (auxiliary
118 cebix 1.24 IOParam block was not in Mac address space and FSItem parent IDs
119     didn't get swapped) [Lauri Pesonen]

130     Lauri Pesonen's site
131 cebix 1.18 - removed the MemoryDispatch() replacement routine; the routine
132     in the ROM is now always used; this fixes the MacOS 8 Finder
133     copying bug and also most "unimplemented trap" errors on MacOS
134     bootup; yeah :-)
135     - a warning is issued if the ROM seems to require an FPU but FPU
136     emulation is turned off
137 cebix 1.12 - medium removal is allowed in CDROMExit()
138 cebix 1.18 - added (incomplete) emulation of 68040 instructions (CINV, CPUSH,
139     MOVE16 (Ax)+,(Ay)+, and FPU stack frames), enough to boot MacOS

491     window mode (with a specified window size) or DGA mode
492     - Unix/video_x.cpp: DGA mode supports 15, 16 and 32 bit modes (packed
493     24 bit pixels don't work)
494     - Unix/Makefile.linux: added -D_REENTRANT to compiler flags
