I have merged in the first round of changes needed for openchrome to
work with xorg 1.4. On my K8M800 it mostly works on both xorg 1.3 and
xorg 1.4. If other people could please test I will appreciate it and
try to fix bugs as fast as possible.
Hi Jon,
I've tested it with a CLE266, but I can't set the resolution to
1024x768. With the trunk-version I can.
Some snippets from /var/log/Xorg.0.log:
X.Org X Server 1.4.0
...
(--) VIA(0): Detected VIA VT3122 (CLE266)-EPIA M/MII/....
(II) VIA(0): Detected MemClk 15
(II) VIA(0): Detected MemClk 15
(WW) VIA(0): Unknown Memory clock: 15
...
(II) VIA(0): Required bandwidth is not available. (188755764 > 74000000)
With trunk it detects MemClk 4.
In the experimental branch you skip the 'Set up MMIO vgaHW' in
via_driver.c around line 2260. If I remove the return TRUE and do the
setup MMIO vgaHW, then I can set the higher resolutions.
I'm not a driver-programmer, so I really have no idea what this MMIO
vgaHW does. But I can test things and see where they go wrong :))
Bye
Erik-Jan
Please try the attached patch, it reverts some of Jon changes that look
suspicious to my non-programmer eyes too. It applies to the experimental
branch. Please provide the xorg log.
Regards,
Xavier
