    Phoronix: Radeon DRM Power Management Moves Along

    Over the past month or so there has been a lot of work done by Rafa?? Mi??ecki and other open-source driver developers in providing open-source power management support under the ATI Radeon DRM code-base. In fact, the power management support has been the hold-up for moving the Radeon kernel mode-setting support out of the staging area of the Linux kernel, which is expected to still happen with the Linux 2.6.33 kernel. Over the past few days things have heated up even more with Rafal pushing out several new versions of his power management patches, which compared to earlier revisions from weeks ago is now leveraging the R600/700 IRQ support...

    can any of the developers give a rough estimate when we should see some usable pm with dynamic clocking and the like?

    I'm not a developer, but it is quite likely to appear in 2.6.34, though of course the correct answer is that they will appear when they are done
