Take care of this restriction in max_width. Without this patch, when 5k content is sent on HDR plane with NV12 content, FIFO underrun is seen and screen blanks out. v2: Addressed review comments from Ville. Added separate functions for max_width - for HDR and SDR v3: Addressed review comments from Ville. Changed names of HDR and SDR max_width functions to icl_hdr_plane_max_width and icl_sdr_plane_max_width Reviewed-by: Ville Syrjälä Signed-off-by: Yashashvi Shantam --- .../gpu/drm/i915/display/skl_universal_plane.c | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/display/skl_universal_plane.c b/drivers/gpu/drm/i915/display/skl_universal_plane.c index 28890876bdeb..e7205a53dc2f 100644 --- a/drivers/gpu/drm/i915/display/skl_universal_plane.c +++ b/drivers/gpu/drm/i915/display/skl_universal_plane.c @@ -420,7 +420,17 @@ static int icl_plane_min_width(const struct drm_framebuffer *fb, } } -static int icl_plane_max_width(const struct drm_framebuffer *fb, +static int icl_hdr_plane_max_width(const struct drm_framebuffer *fb, + int color_plane, + unsigned int rotation) +{ + if (intel_format_info_is_yuv_semiplanar(fb->format, fb->modifier)) + return 4096; + else + return 5120; +} + +static int icl_sdr_plane_max_width(const struct drm_framebuffer *fb, int color_plane, unsigned int rotation) { @@ -2108,7 +2118,10 @@ skl_universal_plane_create(struct drm_i915_private *dev_priv, if (DISPLAY_VER(dev_priv) >= 11) { plane->min_width = icl_plane_min_width; - plane->max_width = icl_plane_max_width; + if (icl_is_hdr_plane(dev_priv, plane_id)) + plane->max_width = icl_hdr_plane_max_width; + else + plane->max_width = icl_sdr_plane_max_width; plane->max_height = icl_plane_max_height; plane->min_cdclk = icl_plane_min_cdclk; } else if (DISPLAY_VER(dev_priv) >= 10) {
