Just updated my driver to latest experimental branch revision. I have VN800 Unichrome Pro IGP. Everything seems to be ok, even Xv and XvMC, but two things:
1) when I enable EXA acceleration, X freezes at startup.
2) sometimes when I switch between virtual desktops or just scroll
something in applications, I get some artifacts appearing on the
screen. They disappear when I switch dekstops again. I can reproduce
this if I open X.org log in Vim in Gnome Terminal and then hold "PgDn"
for a few seconds. Text in terminal is quickly scrolled and after a
few seconds screen is corrupted.
The good thing is that "EnableAGPDMA" "false" is not needed to use X
anymore. Unfortunately, AFAIK my xorg-server is not compiled against
libpciaccess too.
Here's a part of my xorg.conf:
Section "Device"
Identifier "VIA Unichrome Pro"
Driver "openchrome"
# Option "EnableAGPDMA" "false"
# Option "AccelMethod" "EXA"
# Option "ExaScratchSize" "8192"
# Option "MaxDRIMem" "16384"
# Option "MigrationHeuristic" "greedy"
Option "ActiveDevice" "LCD"
# Option "NoXVDMA" "true"
Option "VBEModes" "true"
Option "VBESaveRestore" "true"
Option "DisableIRQ" "true"
BusID "PCI:1:0:0"
EndSection
My xorg.log is attached.
