0.22 on a Via SP13000 anyone?

I thought I'd dig out my old Via Epia SP13000 mini-ITX board as a spare
frontend for guests etc. It was retired about 3 months ago having run
really well for 4 years. With 0.22 loaded, I get very very slow video & TV
playback - something like 3-4 frames in a burst and then nothing for 2
seconds, then another 3-4 frames.

This is a typical log from the 0.22 frontend.

Comparing that to an old log I found from 0.21

I'm seeing the following error in Xorg.0.log
(EE) CHROME(0): [XvMC] ViaXvMCCreateSurface: Too many surfaces !

which makes me think that its a 0.22 specific problem as I'm running the
904 openchrome driver, the same as on 0.21 but I have updated the kernel
from 2.6.25 to 2.6.30 (the versions in between seem to have DRI driver
problems with openchrome). One other oddity - I can't seem to get it to
run realtime.

Something to do with the size of the surfaces. I don't remember the
details any more, but a quick troll of the archive retrieved something I
wrote earlier this year.

This lets xvmc create its surfaces.
You also need to, or course, have the libViaXvMC file listed in
XvMCConfig, to have explicitly listed all the extra modules in your
xorg.conf, and ensured that DRI is set to mode 666.

Since you are resurrecting the box, you probably have these already set.
The surfaces issue is quite obscure.

I have a workaround - I've downgraded from a 2-6-30 kernel to my last
known good one of 2.6.25 (and downgraded udev to match) and its OK now.
Looks like the DRM problem that arrived in 2.6.25+ hasn't been patched in
the Gentoo patchset for 2.6.30 :-(

I've not found a definitive answer yet on exactly what the problem is but
I guess its a cleanup for other chipsets and nobody from Via has bothered
to put in the fixes for their systems.

Only difference I can find is that I have a agpgart module in 2.6.25 but
not for 2.6.30

I always used the openchrome drivers, not the Via versions. If you
aren't maybe you should.

Hi Geoff

I've been running openchrome since before it split from unichrome - I've
also checked that all the patches are in place for slub memory allocation
and tried changing from slab to slub on the later kernel to no avail.

I've just tried MythMusic on this old underpowered box and it segfaults -
almost as quick as when I try to play an iso image!! I'll be playing with
gdb when I get round to it - this is starting to get too much like my day
job...
