Hi,
When testing a tv card on a computer with
01:00.0 VGA compatible controller: VIA Technologies, Inc. Chrome9 HC IGP
(rev 01)
it will always lock. The attached patch/hack corrects the lock problem
(still
need to find out what saa7134 card/tuner will "hopefully" work :-)
If testing some other branch/release it is also required to patch
src/via_swov.c, but the change in svn trunk is better then just adding a
counter to the busy loop...
BTW, Probably asking Xavier :-), what is the state of the VX800 support?
I tested it again, and now randr_branch is not working in a new model,
now a 1024x600 panel.
It did work, to some extent with the 800x640 panel (I was expecting
openchrome developers would receive a test computer or something :-)...
