I patched my radeon driver with patches from #15371, and it reduces
migration a lot.
The same gnome-system-monitor test case dropped from 20% to 5% of CPU.
I didn't noticed any regression. Is there something preventing from
pushing it to master ?
While I am at this, the next CPU killer seems to be this one (browsing
the internet triggers this) :
R200CheckCompositeTexture: Unsupported picture format 0x1011000
This time I checked bugzilla, I found nothing about it.
Thanks a lot for your help and your hard work !
