Priority: medium
Bug ID: 69395
Assignee: dri-devel@lists.freedesktop.org
Summary: [DPM] Forcing lowest power state when no display is
attached is bad because of OpenCL
Severity: normal
Classification: Unclassified
OS: All
Reporter: darkba...@linuxsystems.it
Hardware: Other
Status: NEW
Version: XOrg CVS
Component: DRM/Radeon
Product: DRI
Actually I can't use my HD 7950 with KDE becuase of
https://bugs.freedesktop.org/show_bug.cgi?id=69341
https://bugs.freedesktop.org/show_bug.cgi?id=64297
so I attached my display the Intel HD 4000.
I still do bitcoin mining (OpenCL) on the 7950 and I notice it doesn't switch
to higher power states anymore (everything works flawlessly if I attach the
display to the 7950). Forcing the card to the lowest power state if no display
is attached is a bad behavious because of GPGPU computing.
I'm using Linux 3.12-pre (drm-next).
