The board is basically implemented. It's just a dummy slot ROM
with no driver or primary/secondary init, that looks enough
like the Apple EtherTalk card. The DP8390 controller chip
has its address space implemented, and some of its registers
work. Lots more work to do on that
With slog() tracing enabled, you can see A/UX try to send a
multicast ethernet frame, then give up waiting for some kind
of response from the chip, then decide that the ethernet
controller is dead and print an error to console
- #ifdef __LITTLE_ENDIAN__ is not how you check for little endianness
- Also fixed the last pointer-to-int warnings on GCC
Also, shout out to Neozeed for figuring out how to compile this on windows!
- 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
- 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
- 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
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
- 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
- Converted condition-code + physical_get/set switch statements to jump tables
- Moved the pmmu_cache lookup code out of translate_logical_addr
- Broke MOVE into move-to-datareg, -from-datareg, and datareg-to-datareg
- Fixed UFS code to ignore high 32 bits of inode size (it sometimes contains garbage)
- Support for zero-length reads in scsi.c + 256kb read/write buffer
- pushing interrupt stack frames now actually changes the priority mask
- Updated the READMEs, screencaps for 0.0.2
