There is a bug in hdmi_deep_color_possible() - we compare pipe_bpp <= 8*3 which returns true every time for hdmi_deep_color_possible 12 bit deep color mode test in intel_hdmi_compute_config().(Even when the requested color mode is 10 bit through max bpc property) Comparing pipe_bpp with bpc * 3 takes care of this condition where requested max bpc is 10 bit, so hdmi_deep_color_possible with 12 bit returns false when requested max bpc is 10.(Ville) v2:Add suggested by Ville Syrjälä Suggested-by: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Signed-off-by: Aditya Swarup <aditya.swarup@xxxxxxxxx> Cc: Jani Nikula <jani.nikula@xxxxxxxxx> Cc: Manasi Navare <manasi.d.navare@xxxxxxxxx> Cc: Clinton Taylor <Clinton.A.Taylor@xxxxxxxxx> --- drivers/gpu/drm/i915/intel_hdmi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_hdmi.c b/drivers/gpu/drm/i915/intel_hdmi.c index 991eb362ef4f..74f2dcb8b1ad 100644 --- a/drivers/gpu/drm/i915/intel_hdmi.c +++ b/drivers/gpu/drm/i915/intel_hdmi.c @@ -2159,7 +2159,7 @@ static bool hdmi_deep_color_possible(const struct intel_crtc_state *crtc_state, if (bpc == 10 && INTEL_GEN(dev_priv) < 11) return false; - if (crtc_state->pipe_bpp <= 8*3) + if (crtc_state->pipe_bpp < bpc * 3) return false; if (!crtc_state->has_hdmi_sink) -- 2.17.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
