Hello all,
I suspect this commit in 6.16-rc7 has broken acceleration with Mesa's
nouveau drivers on my machine.
Thanks for the report!
Please make sure to keep maintainers in the loop, for some reason I was removed
from the recipient list for this regression report.
glxinfo -B reports that I'm using llvmpipe.
Reverting this in 6.16-rc7 restores nouveau acceleration, and glxinfo
then reports: "OpenGL renderer string: NVE7"
I also bisected an issue to this commit. On my laptop, this commit
results in an intermittent desktop crash (Xorg segfault) when changing
display scale, which can be more reliably reproduced with:
for x in {1..100}; do
xrandr --output eDP-1 --mode 2560x1600 --scale 0.5 --filter nearest
xrandr --output eDP-1 --mode 2560x1600 --scale 1 --filter nearest
done
I won't have time to work on fixing my patch before the merge window,
let's just revert it.
@Arnd: Yes, given the short timeframe I think that's the best. Can you please
send the revert?
