    Subject[RFC v3 0/4] Implement full clockgating for Kepler1 and 2
    Date
    Next version of my patchseries for adding clockgating support for
    kepler1 and 2 on nouveau. The first version of this series can be found
    here:

    https://patchwork.freedesktop.org/series/36504/

    Some very important changes:
    - Fix gf100_clkgate_init() to actually write registers! This got broken
    in the last version by accident
    - Dump the register packs and the resulting register writes into
    nvkm_trace() in gf100_clkgate_init() so we can make sure this doesn't
    happen again
    And some more minor changes:
    - Make all SLCG/BLCG mmiopacks for kepler2 static

    Additionally, I just discovered that these patches have a higher chance of
    crashing your card if you reclock under load. However, reclocking under
    load has never been supported by nouveau in the first place and has
    always caused trouble so that's nothing new :). Reclocking while not
    under load with powergating works A-OK.

    Lyude Paul (4):
    drm/nouveau: Add support for basic clockgating on Kepler1
    drm/nouveau: Add support for BLCG on Kepler1
    drm/nouveau: Add support for BLCG on Kepler2
    drm/nouveau: Add support for SLCG for Kepler2
