One other comment > below. Yes, this is for the apply_clocks_adjust_rules callback. I updated the patch description as below drm/amd/powerplay: apply clocks adjust rules on power state change This add the apply_clocks_adjust_rules callback which is used to validate the clock settings on a power state change. > > > > Change-Id: I2c4b6cd6756d40a28933f0c26b9e1a3d5078bab8 > > Signed-off-by: Evan Quan <evan.quan at amd.com> > > --- > > drivers/gpu/drm/amd/powerplay/hwmgr/vega12_hwmgr.c | 162 > +++++++++++++++++++++ > > drivers/gpu/drm/amd/powerplay/hwmgr/vega12_hwmgr.h | 2 + > > 2 files changed, 164 insertions(+) > > > > diff --git a/drivers/gpu/drm/amd/powerplay/hwmgr/vega12_hwmgr.c > > b/drivers/gpu/drm/amd/powerplay/hwmgr/vega12_hwmgr.c > > index a227ace..26bdfff 100644 > > --- a/drivers/gpu/drm/amd/powerplay/hwmgr/vega12_hwmgr.c > > +++ b/drivers/gpu/drm/amd/powerplay/hwmgr/vega12_hwmgr.c > > @@ -1950,6 +1950,166 @@ static int vega12_print_clock_levels(struct > pp_hwmgr *hwmgr, > > return size;
