from MirceaKitsune
I have moved on to testing the various kernel parameters avail=
able for my
driver and card. As was pointed out by malcolmlewis on the openSUSE forums,
they can be listed with the following commands:
modinfo amdgpu
systool -vm amdgpu
I tested nearly half of them today, almost none made any difference. There =
were
however a few settings that appeared to influence the frequency of the free=
ze.
The most notable one of all seems to be the following:
amdgpu.moverate=3D4
With no parameters changed, the freeze now occurs roughly once per 30 minut=
es
in Xonotic. With that move rate limited to 4MB/s however, I seemingly reduc=
ed
it to only 90 minutes! The FPS will constantly drop and recover, but that m=
akes
sense as this setting explicitly limits the buffer migration rate.
I may test other variables in the days to come, but for now I'm hoping this
offers at least some clue to get things started. My feeling is that the vid=
eo
card may be slowly loaded with information until something fills up, or per=
haps
some events throw too much data in at once and it reaches a bottleneck?
