Summary: UVD performance regression on linux-3.12-rc
Severity: normal
Classification: Unclassified
OS: All
Reporter: johannes.hi...@fem.tu-ilmenau.de
Hardware: Other
Status: NEW
Version: DRI CVS
Component: DRM/Radeon

When playing h.264 videos with UVD support, the video is sluggish and mplayer
shows the "Your system is too SLOW to play this!" message after a few seconds.
git bisect points me to:

drm/radeon/dpm: use multiple UVD power states (v3)
Use the UVD handle information to determine which
which power states to select when using UVD. For
example, decoding a single SD stream requires much
lower clocks than multiple HD streams.
v2: switch to a cleaner dpm/uvd interface
v3: change the uvd power state while streams
are active if need be
