Hi,
The introduction of commit dc911f5bd8aa (drm/i915/edp: Allow alternate
fixed mode for eDP if available.) causes severe performance degradations
on my system, especially noticeable while playing video games. There are
some workarounds though:
- - Setting the screen refresh rate below 60 Hz. Might be inconvenient in
certain circumstances.
- - Using Jim Bride’s patch¹. According to some people it cures the issue.
Contrary to the above workaround, this one I did not test. It should
be noted that it seems to have fall through the cracks as I don’t see
any reference to it in Linus' tree.
As we are going to use 4.15.x for some more time, I propose that we
revert the aforementioned commit until a solution is found upstream.
Thought?
Cheers,
Vincent
