From: "Kumar, Mahesh" <mahesh1.kumar@xxxxxxxxx> Don't always use bytes_per_pixel using y_plane=0, instead use it according to pixel format. If NV12 use y_plane eqal to 1 Signed-off-by: Kumar, Mahesh <mahesh1.kumar@xxxxxxxxx> --- drivers/gpu/drm/i915/intel_pm.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_pm.c b/drivers/gpu/drm/i915/intel_pm.c index 9df9e9a..68f21b9 100644 --- a/drivers/gpu/drm/i915/intel_pm.c +++ b/drivers/gpu/drm/i915/intel_pm.c @@ -3185,7 +3185,9 @@ static bool skl_compute_plane_wm(const struct drm_i915_private *dev_priv, if (latency == 0 || !cstate->base.active || !fb) return false; - bytes_per_pixel = drm_format_plane_cpp(fb->pixel_format, 0); + bytes_per_pixel = (fb->pixel_format == DRM_FORMAT_NV12) ? + drm_format_plane_cpp(fb->pixel_format, 1) : + drm_format_plane_cpp(fb->pixel_format, 0); method1 = skl_wm_method1(skl_pipe_pixel_rate(cstate), bytes_per_pixel, latency); -- 2.4.3 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
