            Bug ID: 85021
           Summary: radeon: Allow one to set "mid" to
                    power_dpm_force_performance_level
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.16.2
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: higuita@gmx.net
        Regression: No

On a radeon module with dpm enable, one can set the
power_dpm_force_performance_level to auto, low and high. All fine, but my card
have a mid performance setup and is very useful, as the low is too slow when i
have some contant graphic usage (usually tvtime running), but auto and high are
too fast and hot for that usage, wasting energy and overheating the system
without need.

If i could setup the mid profile, the performance would be good, but not the
card maximum.

So the current setup is good for "little"/"a lot" GPU usage, but is missing the
mid support for those "moderate" GPU usage where the low is too litle and the
high is too much.
