  • KMS and DRI2 work fine for me with mesa 7.6 in updates-testing:
    Code:
    yum --enablerepo=updates-testing upgrade mesa-dri-drivers
    The 3D performance regression is evident, but Compiz + DRI2 work quite fine!
    This is on a Radeon 9500 AGP.

      Cool, but what does DRI2 have to do with power options?

        Nothing at all? Mostly concentrating modesetting and memory management in kernelspace led/will lead to better (read: one that has access to both modesetting and acceleration and can do power management at the right time and in the right place without the risk of hangs or such ) power management after power management gets ported to kernel too. (and this moving/porting power management to DRM is the thing bridgman talked about)

        • Do power-saving options still work with KMS, DRI2 and xorg 1.7? I ask because that is the current standard configuration in Arch Linux now and with it power saving options seem not be working anymore, and without KMS X hangs. I have these messages in Xorg.log:

          (WW) RADEON(0): Option "DynamicPM" is not used
          (WW) RADEON(0): Option "ForceLowPowerMode" is not used
          (WW) RADEON(0): Option "ClockGating" is not used

          What is the status here?

          BTW, the limitation that OpenGL wouldn't output to a portion of my second monitor at all is gone! Also most other things seem to work fine, only Radeon xv is not working on the second monitor, I get a black screen there, which is no problem since I can use OpenGL or X11 outputs in mplayer.

          Thanks for any info, signorRossi.

            There's no low power options yet with kms.

            You may need a newer radeon drm kernel modules and/or ddx depending on what versions you are currently using.

            • That was a quick response, thank you.
              Seems that I have to wait again for a little (I hope it doesn't take too long ) or try to fix the X crash without KMS.

              signorRossi.

              EDIT: Tried again without KMS and it seems to work now (Arch has nice info on the WIKI regarding how to do it).

              • I seem to get cursor corruption when "ForceLowPowerMode" is enabled on my rv635 (HD3650), print screen seems not to store/save this corruption.

                I'm on a Ubuntu 9.10 install with xorg-edgers ppa and latest mainline kernel 2.6.32-rc6.

                Edit: Option "ExaNoDownloadFromScreen" "TRUE" fixes it
