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 Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20221003111544.8007-3-ville.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 @@ -5403,11 +5403,13 @@ skl_compute_wm_params(const struct intel modifier == I915_FORMAT_MOD_Yf_TILED || modifier == I915_FORMAT_MOD_Y_TILED_CCS || modifier == I915_FORMAT_MOD_Yf_TILED_CCS || - modifier == I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS; + modifier == I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS || + modifier == I915_FORMAT_MOD_Y_TILED_GEN12_MC_CCS; wp->x_tiled = modifier == I915_FORMAT_MOD_X_TILED; wp->rc_surface = modifier == I915_FORMAT_MOD_Y_TILED_CCS || modifier == I915_FORMAT_MOD_Yf_TILED_CCS || - modifier == I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS; + modifier == I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS || + modifier == I915_FORMAT_MOD_Y_TILED_GEN12_MC_CCS; wp->is_planar = intel_format_info_is_yuv_semiplanar(format, modifier); wp->width = width;
