Plane color space conversion is different on GLK and later platforms causing the colors to display incorrectly. Ville's plane color space property patch series in review will fix this issue. - Restricted the NV12 case in intel_framebuffer_init to SKL and BXT only. v6: Rebased (me) v7: Addressed review comments by Ville Restricting the NV12 to BXT for now. v8: Rebased (me) Tested-by: Clinton Taylor Reviewed-by: Clinton Taylor Signed-off-by: Chandra Konduru Signed-off-by: Nabendu Maiti Signed-off-by: Vidya Srinivas --- drivers/gpu/drm/i915/intel_display.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 6cf8806..615c7cc 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -14095,6 +14095,14 @@ static int intel_framebuffer_init(struct intel_framebuffer *intel_fb, goto err; } break; + case DRM_FORMAT_NV12: + if (!IS_BROXTON(dev_priv)) { + DRM_DEBUG_KMS("unsupported pixel format: %s\n", + drm_get_format_name(mode_cmd->pixel_format, + &format_name)); + goto err; + } + break; default: DRM_DEBUG_KMS("unsupported pixel format: %s\n", drm_get_format_name(mode_cmd->pixel_format, &format_name));
