    [rfc] drm/radeon/kms: pm debugging check for vbl. · f735261b
    Dave Airlie authored
    This patch adds a check on avivo chips to see if we are in the VBL
    region for the active crtcs when we trigger the engine change.
    
    I appear to have glitches locally on pm transistion (not sure all
    fixes are in yet) and this at least seems to be correct here,
    maybe others can test on systems with no glitches.
