--- Comment #1 from Kenneth Graunke <kenneth at whitecape.org> ---
I can reproduce a 20% difference, but it's...actually a 20% improvement. My
system is a Kabylake GT2 (Dell XPS 15 9650), Kernel 4.20.2-arch1-1-ARCH,
xserver 1.20.3.
It looks like a2ec78883f4 is slow, and 0b44644ca68 (genxml: Consistently use a
numeric "MOCS" field) is 20% faster. Needless to say, this is not expected,
that patch was supposed to just change the mechanism for programming MOCS, not
the actual values of MOCS used anywhere.
