Take the gen12+ MC CCS modifier into account when calculating the watermarks. Othwerwise we'll calculate the watermarks thinking this Y-tiled modifier is linear. The rc_surface part is actually a nop since that is not used for any glk+ platform. v2: Split RC CCS vs. MC CCS to separate patches Cc: stable@vger.kernel.org Fixes: 2dfbf9d2873a ("drm/i915/tgl: Gen-12 display can decompress surfaces = compressed by the media engine") Reviewed-by: Juha-Pekka Heikkila Signed-off-by: Ville Syrj=C3=A4l=C3=A4 Link: https://patchwork.freedesktop.org/patch/msgid/20221003111544.8007-3-v= ille.syrjala@linux.intel.com (cherry picked from commit 91c9651425fe955b1387f3637607dda005f3f710) Signed-off-by: Tvrtko Ursulin Signed-off-by: Greg Kroah-Hartman --- drivers/gpu/drm/i915/intel_pm.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) --- a/drivers/gpu/drm/i915/intel_pm.c +++ b/drivers/gpu/drm/i915/intel_pm.c @@ -5309,11 +5309,13 @@ skl_compute_wm_params(const struct intel modifier =3D=3D I915_FORMAT_MOD_Yf_TILED || modifier =3D=3D I915_FORMAT_MOD_Y_TILED_CCS || modifier =3D=3D I915_FORMAT_MOD_Yf_TILED_CCS || - modifier =3D=3D I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS; + modifier =3D=3D I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS || + modifier =3D=3D I915_FORMAT_MOD_Y_TILED_GEN12_MC_CCS; wp->x_tiled =3D modifier =3D=3D I915_FORMAT_MOD_X_TILED; wp->rc_surface =3D modifier =3D=3D I915_FORMAT_MOD_Y_TILED_CCS || modifier =3D=3D I915_FORMAT_MOD_Yf_TILED_CCS || - modifier =3D=3D I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS; + modifier =3D=3D I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS || + modifier =3D=3D I915_FORMAT_MOD_Y_TILED_GEN12_MC_CCS; wp->is_planar =3D intel_format_info_is_yuv_semiplanar(format, modifier); =20 wp->width =3D width;
