    And will also watch koji and/or f12 alpha or rawhide.

    If you use fc11 that makes things pretty complicated and I'd leave my fingers from it. AFAIK fc11 already uses snapshots of a radeon git-branch (radeon-gem-cs3 I'd guess) in order to enable kms and dri2.
    Apparently the new power options haven't made it in that branch, and quite possibly wont until the branch is merged into master again.
    So building from git-master right now will most likely give you a not working X-Server... or if you're lucky "just" kms and dri2 will stop working.

    Thanks. I've not built ati from git before, but can give it a go.

    One thought though - with a number of dependencies between kernel/kms/libdrm/mesa, are there any particular recommendations on building a suitable git version for F11?

    At this point I'm wondering if it just makes sense to wait until the maintainer picks this up.

    @planetf1: The powermanagement-options aren't yet in a release, so you need the git-master version of xf86-video-ati. 6.12.2 is too old.

    I've just tried enabling this on a Thinkpad T60p, but see the following in Xorg.0.log

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

    I have this in the device section in xorg.conf
    #Option "DynamicClocks" "on"
    Option "ClockGating" "on"
    Option "ForceLowPowerMode" "on"
    Option "DynamicPM" "on"

    SW levels are from Fedora 11
    xorg-x11-drv-ati-6.12.2-15.fc11.i586
    kernel-PAE-2.6.29.4-167.fc11.i686

    From xorg log:
    (II) Module radeon: vendor="X.Org Foundation"
    compiled for 1.6.1.901, module version = 6.12.2
    Module class: X.Org Video Driver
    ABI class: X.Org Video Driver, version 5.0
    (--) RADEON(0): Chipset: "ATI Mobility FireGL V5200" (ChipID = 0x71c4)

    Why aren't these options effective, what am I missing?

    Am I mistaken in thinking these changes made it into the fc11 rpm?

    Is there also any way to check the current clock freq?

    Thanks

    Just installed latest xorg git to try this out. The radeon driver hasn't crashed yet, but as a side effect I have a horribly broken evdev keyboard driver now. *sigh* :-/

    (edit: never mind - that was just my xmodmap stuff screwing things up)

    As long as it is for debugging purposes I think it would make sense to show the mhz. I'm also for apply this patch upstream. We linux user want to know whats going on.

    The info is there for debugging purposes at the moment. At some point, we'll get rid of it or make it a debug option.

    Looking at the patch it appears that it only adds the printed clock value, while before it only printed the switch, so no new entries are printed:

    current:
    Power Mode Switch

    with patch:
    Power Mode Switch: %d Mhz
