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
