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: darkbasic@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).
