           Summary: Display flickers when setting power_profile
           Product: DRI
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: egore@gmx.de


When calling something like

echo "low" > /sys/class/drm/card0/device/power_profile

my display flickers a single time. This is okay-ish, but on Microsoft Windows
the clock changes do not cause such a flicker. There has to be some kind of
trick to achieve that and it would be great if this would work an Linux, too.

Tested on vanilla kernel 2.6.39 with libdrm 2.4.26 and xf86-video-ati 6.14.2.

I have this flickering issue too on my HD8650.
But not only moving to high to low profile. It flickers low to high profile
too! This doesn't let us use "dynpm"...

Using Kernel 3.3.5 with mesa/radeon/drm trunk.
