With the latest git mesa, there are major performance drops. First noticed the issue with the 32bit steam game "Move or die", but it seems to affect the whole system. It basically makes the game unplayable. Bisecting pointed me to the following commit: commit 524d4fff9e0e58e812e71bc5ba2c92ffa73bee16 Author: Leo Liu <leo.liu@amd.com> Date: Wed May 3 14:06:35 2017 -0400 amd/common: add vcn dec ip info query Signed-off-by: Leo Liu <leo.liu@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> I tried reverting it, but it doesn't apply cleanly. Running Arch Linux 64 Linux 4.11.2 System the issue was tested on: - Arch Linux 64bit - Linux 4.11.2, AMDGPU driver - Radeon R9 285
Just noticed, this seems to be reverted already during the time I need to setup and bisect mesa.
Hi Fabian, David reverted it and Leo Liu sent an update just in time: Please try with this one: https://lists.freedesktop.org/archives/mesa-dev/2017-May/156930.html Dicussion was here: https://lists.freedesktop.org/archives/mesa-dev/2017-May/156907.html https://lists.freedesktop.org/archives/mesa-dev/2017-May/156931.html Cheers, Dieter

I find it helpful giving exact commit IDs of the builds I'm using (or the version number, whatever is more accurate). Otherwise bug reports don't tend to age well. ;-) In any case, if you're bisection is correct, you should check a build of current HEAD (e1409f730251bf9d7e70046f58392de6e4e98815) and close this bug if appropriate. Otherwise a new biscetion would be required.

Bonus: When you've tested it fine, you can send four (first) 'Tested-by:' ;-)
Thanks, just tested, it works fine after the commit was reverted. Marking this as resolved.
I can reproduce the problem with kernel that has no vcn patch, and the fix sent to mesa-dev list was tested and have issue fixed. Thanks, Leo
