            Bug ID: 65811
           Summary: AMD 7970M (PowerXpress) power management not
                    functioning properly when using Xrandr to offload
                    rendering
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.13-rc1
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: jack@cyphernaut.org
        Regression: No

rc1 appears to have solved my issues of X not starting or crashing when
starting, which I ran into when using the DRM patches on 3.12. However I've run
into another issue:

When I start my laptop, if I do not immediately offload rendering to the
discrete Radeon card (xrandr --setprovideroffloadsink radeon Intel) the state
in vgaswitcheroo will change to 'DynOff', and xrandr --listproviders will no
longer report the radeon as a potentially offload source

Conversely, if I *do* --setprovideroffloadsink to the radeon within a few
seconds after X starts, the state in vgaswitcheroo changes to DynPwr and never
actually turns off (laptop behaves as if runpm was not enabled at all).
