Hello,
kernel test robot noticed a -20.7% regression of phoronix-test-suite.quadray.1.4K.fps on:
commit: 225a8d0bd93eb87fe49947069075260031bad8af ("drm/ast: Implement polling for VGA and SIL164 connectors")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master cc8ed4d0a8486c7472cd72ec3c19957e509dc68c]
testcase: phoronix-test-suite
test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz (Cascade Lake) with 512G memory
parameters:
need_x: true
test: quadray-1.0.0
cpufreq_governor: performance
