This regresses power usage on 4.18. Please revert. https://bugzilla.kernel.org/show_bug.cgi?id=201275
Is it reverted in "upstream" as well? If not, please get the fix in there and then I will be glad to backport it here.
There's no breakage in upstream. This patch addressed breakages in 4.19 specifically due to some other refactoring we did in the driver. I'll try and dig out the exact series of patches this addressed.
So there is no problem in 4.19-rc7? That contridicts the statement of looking in drm-next for the fixes.
Sorry, what statement about drm-next? This patch was for 4.19 and was
not intended for 4.18. It was picked up by Sasha's auto select system for stable.
I thought this thread said that.
Ok, so I should just revert it?
Yes, please.
Thanks,
Alex
