Mach64 driver changes log:
|
|
--------------------------
|
|
April 11, 1998 (Michael Weller)
|
|
VGA Emulation should be used to avoid MACH64 code in get_lut
|
|
(and elsewhere?)

|
NON FUNCTIONAL DRIVER sent for inclusion in 1.2.10
|
|
|
|
It doesn't seem to quite work. Its hardcoded to 640x480x256@60hz for
|
|
a WINTURBO 2mbVRAM and 68860 ramdac - with the 18818 clock.
|
|
The screen has vertical bars thru it... each 64k chunk is a little offset
|
|
and its full of crap. I can't seem to track the problem down. I checked
|
|
the CRTC registers, and dac programming. They are similar to what I got
|
|
from ATI and based on what I yanked from XFree86.
|
|
|
|
Help.
|
|
|
|
Added dac handling code to vgapal.c.
|
|
|
|
Didn't work so I stripped it clean. Removed clock programming...
|
|
fixed the dac to 68860 and clock to 8 - the default clock setting.
|
|
Based code on combination of ATI's SDK and the mach64 x server.
|
|
|
|
Went from a.out to elf.
|
|
Discovered a hell of a lof of segfaults. Due to my attempts to be nice
|
|
and unmap and free any mapped/allocated ram... uncommented worked fine.

Re-synced to pre 1.2.9 from 1.2.7
|
|

|
|
|
|
So I'm lazy (actually busy)
|
|
|
|
Well... I got the updated SDK from ATI. Updated the autodetect function
|
|
to reflect the SDK recommendations. I'm gonna avoid using the Extended
|
|
vga registers to try and maintain compatability with the CT/ET. So all
|
|
work will be done with the Mach64 controller thingy.
|
|
|
|
It now downloads all the necessary data from the rom.

Stuck in a register dumper so I know what I see.
|
|
|
|
It's still a vga driver.

|
This files was created to log all the changes made to svgalib-1.2.7 in
|
|
order to incorporate an ATI Mach 64 driver.
|
|
|
|
libvga.h: The Mach64 has 32 bit registers. The libvga.h doesn't
|
|
have code for inl and outl. These were added.
|
|
vga.h: Well.. gotta tell it there's a new driver.
|
|
Mach64 = 13 ooohh.. lucky number. But its actually
|
|
the 14th driver-- if you count from 0. :)
|
|
vga.c: Added the driver to the list.
|
|
config.h: Added some INCLUDE_MACH64_...
|
|
driver.h: Added the extern driver specs thingy.
|
|
Makefile.aout: stuck a line in their about mach64.c
|
|
|
|
mach64.regs: Named register list.
|
|
mach64.h: Header file.
|
|
mach64.c: Driver.
|
|
mach64.CHANGES: You're look at it.
