Subject: [Bug 52345] New: KMS Power Management have no effect
Date: Sat, 21 Jul 2012 16:30:56 +0000 [thread overview]
Message-ID: <bug-52345-502@http.bugs.freedesktop.org/> (raw)
https://bugs.freedesktop.org/show_bug.cgi?id=52345
Bug #: 52345
Summary: KMS Power Management have no effect
Classification: Unclassified
Product: DRI
Version: XOrg CVS
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: d2xdt2@gmail.com
Using
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD SUMO2
OpenGL version string: 2.1 Mesa 8.0.3
OpenGL shading language version string: 1.20
AMD A4-3400 APU with Radeon(tm) HD Graphics
Fedora 17 64bit
Linux amd 3.4.5-2.fc17.x86_64 #1 SMP Mon Jul 16 20:52:08 UTC 2012 x86_64 x86_64
x86_64 GNU/Linux
According to
http://wiki.x.org/wiki/RadeonFeature
should
echo profile > /sys/class/drm/card0/device/power_method
echo high > /sys/class/drm/card0/device/power_profile
put the GPU in high performance mode and
echo profile > /sys/class/drm/card0/device/power_method
echo low > /sys/class/drm/card0/device/power_profile
in low performance mode.
glxgears gives 60 FPS in both cases, which leads me to beleive that power
management does work.
