Description jorgefm 2018-06-08 08:43:12 UTC

Hi,

I get the next dmesg trace playing an h264 video with a custom player using libmpv-0.28.0. I'm using a debian8 with a vanilla 4.14.24 kernel with the next packages built from a padoka ppa:

mesa 18.1~git1803060730.237c9c~oibaf~x
xserver-xorg-video-amdgpu 1.4.99+git1803011934.7854ac~oibaf~x

The video is played ok, maybe be some slow downs, but this trace is generated

Comment 1 Christian König 2018-06-08 08:48:24 UTC

Sounds like a known issue in kernel 4.14 to me.

Please test with some newer kernel as well, probably best to test with Alex amd-staging-drm-next branch.

Comment 2 jorgefm 2018-06-08 08:56:49 UTC

Thanks Christian for the info! I'll try it... This issues are fixed backporting changes to a LTS kernel version? I ask in order to check in a more recent 4.14 version instead of change to a new version...

Comment 3 devbazilio 2019-07-19 04:57:21 UTC

I have same issue after upgrade from 4.14.111 to 4.14.132. Use of following branch is impossible as it has DisplayCore enabled by default and video decoding works with crucial issue on my AMD GPU chip and only 4.14 kernels don't have DC enabled

Comment 4 Michel Dänzer 2019-07-19 07:54:47 UTC

(In reply to devbazilio from comment #3)
> [...] only 4.14 kernels don't have DC enabled

FWIW, you can always disable DC with amdgpu.dc=0 on the kernel command line.
