from Kyle K
Hello,
I have been having problem with my HD6870 for some time. I experienced it on
4.7/4.8/4.9 kernels (haven't tested earlier). My HD6870 works great out of =
the
box with DPM enabled, I do not have any issues for general use.
I do have a problem with applications that put heavier load on GPU, for exa=
mple
MPV with hw acceleration enabled. My R600 tries to upclock from 300Mhz base=
d
efault but fails with:
Apr 21 00:34:22 xenon kernel: [drm:btc_dpm_set_power_state [radeon]] *ERROR*
rv770_restrict_performance_levels_before_switch failed
Apr 21 00:34:33 xenon kernel: [drm:btc_dpm_set_power_state [radeon]] *ERROR*
rv770_restrict_performance_levels_before_switch failed
I can reproduce this every time with:
$ mpv --hwdec=3Dvdpau --vo=3Dvdpau <foo.mkv>
The video playback follows but it is very choppy as you would imagine.
Attempting to use VAAPI pipeline for hw decoding results in hard system cra=
sh
with blank screen after just few seconds of playback. I can reproduce it al=
ways
with:
$ mpv --hwdec=3Dvaapi --vo=3Dvaapi <foo.mkv>
I'm booting with radeon.dpm=3D0 as a workaround, vdpau hw decoding is butter
smooth and playback in mpv is very reliable, however temps and noise is not=
as
great :(
I used to run Arch on latest 4.10 kernel but recently I'm playing around wi=
th
Solus so I'm on 4.9.22, here are stock settings with DPM enabled on Solus
system that I have this problem:
