I've adapted the experimental tvout code for Radeon/r128 in gatos cvs to
Mach64 and I'm atttaching the patch (can be applied to atimode.c in ati.2
or the mach64 DRI branch). It works for me, but it has the same problem
of garbling the text console and mode switching with Ctl-Atl-+/- doesn't
work correctly. However, I did have success with enabling tv-out even if
it's not plugged in and detected by the BIOS at boot. This uses card BIOS
functions specific to Rage LT Pro (which is what I have), Rage XL, and
Rage Mobility (mach64 variety), but only if one of these chips is
detected. Since the VBE functions are called for each mode switch, I can
switch between my laptop LCD and TV by switching to a console, plugging in
or unplugging the TV cable, and switching back to X. I changed the code
from Radeon to recognize a display width of 800 (rather than 832), so I
can use 640x480, 800x600 and 1024x768 without specifying custom modelines.
However, it should also work with custom modelines as long as they use
640, 800, or 1024 width and 15, 16, or 32 bpp.
This patch is of course rough and experimental, and I've only tested it on
my setup, so the usual caveats apply -- your tv/monitor might blow up,
etc. ;) Peter, since you worked on the r128 patch, can you take a look
at this?
