Current DBuf slices update wasn't done in proper place, especially its "post" part, which should disable those only once vblank had passed and all other changes are committed. v2: Fix to use dev_priv and intel_atomic_state instead of skl_ddb_values (to be nuked in Villes patch) v3: Renamed "enabled_slices" to "enabled_dbuf_slices_num" (Matt Roper) v4: - Rebase against drm-tip. - Move post_update closer to optimize_watermarks, to prevent unneeded noise from underrun reporting (Ville Syrjälä) Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> --- drivers/gpu/drm/i915/display/intel_display.c | 37 +++++++++++++++----- 1 file changed, 28 insertions(+), 9 deletions(-)
