    Phoronix: Open ATI Driver To Receive PowerPlay Push?

    Besides the Radeon DRM improvements (and Radeon HDMI KMS audio) to be found in the Linux 2.6.33 kernel, there is more to be thankful for this holiday season when it comes to the open-source support. Up to this point when it comes to power management for ATI's kernel mode-setting support the work (Radeon DRM Power Management Moves Along) has been largely done by Rafa?? Mi??ecki, an independent open-source developer...

    I have three acpi sensors, two for cpus and one for gpu, so I can read those temps just with acpi tools. I'm sure that it's gpu temp because reading it through aticonfig (using catalyst) returns the same value.

    I'm sure everything is well-configured because if I switch to catalyst temperatures are ok, gpu is around 50 and also cpu are ok.
    I'm not surprised of those temps since I also get 64-65 degrees using ForceLowPowerMode in xorg.conf without KMS.

    Are you sure your CPU isn't running with the "performance" CPU scaling governor? Did you take a look at powertop? A simple top, for 100% CPU processes?

    Sorry if all this sounds a bit stupid... I'm just alarmed by those 70 degrees.

    I have hd4570 on dell laptop.
    Whoa! The 0010 patch is new to me, thank you for the info. I'll be trying it soon.

    Did you build drm and radeon as modules or built in?

    If they're modules, append radeon.modeset=1 radeon.dynpm=1 to the kernel commandline, or modprobe the module with options modeset=1 dynpm=1

    You can set modprobe rules in the /etc/modprobe.d/ directory, with a line like:

    options radeon modeset=1 dynpm=1


    Thanks for the 0010 tip.

    The KWin issues are probably a Mesa regression. Mesa broke KWin effects badly in the past, but it was fixed (the commit reverted). Now it's back, though not nearly as bad as it used to be.

    I've moved to Arch Linux's AUR package mesa-full 20100117 (with gallium enabled) on kernel 2.6.33rc4 + Ati PM patches and xf86-video-ati-git.

    I must say the patches do a really good job. I get 52C in idle while Catalyst managed 50C. That's really really good

    Unfortunately something's still wrong. I'm getting the following warning in glxgears, though they themselves work:
    do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
    I've installed radeon_ucode firmware stuff so that the IRQ patches will be working, but this warning doesn't go away.

    Also, I don't know if it's a sideeffect of not having Vblank (that's what the IRQs are for, yup?) in OpenGL, but sometimes in Kwin (KDe 4.4 RC1) I'm getting yellow translucent bands instead of window drop-shadows. These didn't appear when using kernel 2.6.32.3 with radeon UMS. Anyone has a clue?
