    1) Update kernel to 3.16 or newer
    2) Install oibaf's or edgers Mesa ppa
    3) $ sudo su root
    4) $ echo 0f> /sys/class/drm/card0/device/pstate
    where 0f is the desired power state and /card0 is your card's id

    Missed a step.

    1) Update kernel to 3.16 or newer
    2) Install oibaf's or edgers Mesa ppa
    3) $ sudo su root
    4) $ NvReclock=1
    5) $ echo 0f> /sys/class/drm/card0/device/pstate
    where 0f is the desired power state and /card0 is your card's id

    So. Reclock it's not automatic? You have to set the desired clock state?

    Absolutely NOT. In fact it's now hidden in 3.17 kernel. So the new way to test this out is


    1) Update kernel to 3.17
    2) Add the following kernel boot parameter: nouveau.pstate=1
    3) Install oibaf's or edgers Mesa ppa
    4) $ sudo su root
    5) $ export NvReclock=1
    6) $ echo 0f> /sys/class/drm/card0/device/pstate

    There really should be a central wiki that documents these steps and current hardware support status.
