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
