           Summary: Dynamic power management does not work on HD5870
           Product: DRI
           Version: XOrg CVS
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: darkbasic4 at gmail.com


I recently switched from an HD3870 to an HD5870, before dynpm did work
flawlessly (expect of a bit o flickering), but now it doesn't work anymore (it
keeps 'high' and does not switch to the lower power states). Instead 'low'
power profile does work even better than the 3870, it goes from 70 to 45°C
instead of 55°C.

linux-3.0.0-rc3, mesa git master, libdrm git master, fx86-video-ati git master,
xorg-server 1.10.3

Let me know which kind of information do you need.
