0322e558b4 Preliminary support for ethernet/multiple screens in cocoa client 2015-09-13 00:39:58 -07:00

476a8bb570 Major speed improvements (25-50%)
There may be bugs lurking in it. On my Core i7 macbook pro,
shoebill now runs so fast that SetUpTimeK() on A/UX 3 hangs.
(SetUpTimeK tries to time a dbra loop, and refuses to accept any
speed faster than a certain threshold, which shoebill is now
surpassing. If you see A/UX hanging early in boot, it's probably
that.)

- Added a new specialized cache for instruction stream reads
-- This also lets us distinguish between data and instruction
   reads, which the 68020 does. Instruction reads are now done
   with the correct function code (2 or 6), although that
   doesn't currently fix or improve anything currently
- Added an obvious condition code optimization, dunno how I missed
  it earlier
- Other little changes

18c5a2b261 Newfpu works enough to "boot" A/UX
... but that's not saying much

b29c69453e Mostly-working ethernet and various changes
This may break the linux/windows builds - I haven't tried to compile
on those platforms yet.

- Ethernet is more or less working with a hardcoded /dev/tun0 network interface
and hardcoded MAC address, though there's no automatic ifconfig/route
configuration yet.

- Instructions TAS and ILLEGAL are implemented now

- Fixed some bugs in MOVEP

- Implemented some other instruction disassemblers

- Other little changes

6773dd6020 Tweaks to SDL GUI, video driver, and FPU

- Fewer video driver-related crashes
- Cleaned up the SDL GUI
- Bumped up cocoa GUI to v0.0.4

f051d42597 Resuscitated the toby frame buffer
- Integrated it into the SDL GUI (via the "toby" cli parameter)
- It does not include the card ROM, so it will not run on A/UX 1, 2, or 3

1bee24316c Now more Windows-friendly
- cpu_thread now stops and waits on a pthread condition variable, rather
  than sleep(1)ing and waiting to be pthread_kill()'d. Signals don't
  work well on Windows, apparently.
- fopen() now open binary files with the "b" mode
- the keymap red-black tree no longer casts pointers to ints, because
  mingw/gcc complains about it
- added a dumb batch script to compile the sdl gui on windows
- {n,h}to{h,n}{s,l,ll} is now handled better on windows

952fe7ae89 Linux SDL GUI + bug fixes + printf->slog
- sdl-gui/sdl.c is a tiny, basically working SDL2-based GUI that can compile and run on linux.
  It still needs PRAM integration and a config file.

- Fixed a dumb bug in shoebill_initialize that was causing sporadic crashes

- Replaced a million printf() calls with slog(), to make the SDL client run more quietly on the CLI

- Added more corruption checking to alloc_pool

5c1fdf6b73 VIA Timers + 16/32-bit video support
- VIA timers should probably work now, although it turns out A/UX rarely uses them
  (only during startup to time a dbra loop and other stuff)

- Updated video.c and the fake nubus video card driver to support "thousands"
  and "millions" of colors when 32-bit QuickDraw is available

f4f546deb5 Restart + PRAM integrated into GUI + misc
Restart/shutdown now work (most of the time)
PRAM is now integrated into the GUI
The real time clock sorta works, but is a bit wonky
Full-screen support
Lots of other little bug fixes

d19c17812c New debugger + inital PRAM/real-time clock + fixes
- Refactored VIA rega/b implementation
  - Timers don't "work" yet, but they work a little better
  - Split rega/b into input and output versions
  - Fixed a bug that would mistake VIA1 accesses for VIA2

- Added basic support for PRAM and the RTC, although they're not
  wired into the GUI yet

- Replaced every *alloc() call with an alloc_pool call, which is
  a start toward supporting clean restarts

- Replaced ea_addr, ea_read, ea_write, and ea_read_commit with
  jump tables

- Got rid of ~inst() macro in cpu.c

- added a GLUT-based debugger
