Fix this by adding vsc sdp revision 0x6 and length 0x10 into intel_dp_vsc_sdp_unpack Signed-off-by: Jouni Högander Reviewed-by: Animesh Manna Link: https://patchwork.freedesktop.org/patch/msgid/20240607134917.1327574-4-jouni.hogander@intel.com --- diff --git a/drivers/gpu/drm/i915/display/intel_dp.c b/drivers/gpu/drm/i915/display/intel_dp.c index b5915c23302f9..653b20f9576ce 100644 --- a/drivers/gpu/drm/i915/display/intel_dp.c +++ b/drivers/gpu/drm/i915/display/intel_dp.c @@ -4450,7 +4450,8 @@ static int intel_dp_vsc_sdp_unpack(struct drm_dp_vsc_sdp *vsc, vsc->length = sdp->sdp_header.HB3; if ((sdp->sdp_header.HB2 == 0x2 && sdp->sdp_header.HB3 == 0x8) || - (sdp->sdp_header.HB2 == 0x4 && sdp->sdp_header.HB3 == 0xe)) { + (sdp->sdp_header.HB2 == 0x4 && sdp->sdp_header.HB3 == 0xe) || + (sdp->sdp_header.HB2 == 0x6 && sdp->sdp_header.HB3 == 0x10)) { /* * - HB2 = 0x2, HB3 = 0x8 * VSC SDP supporting 3D stereo + PSR @@ -4458,6 +4459,8 @@ static int intel_dp_vsc_sdp_unpack(struct drm_dp_vsc_sdp *vsc, * VSC SDP supporting 3D stereo + PSR2 with Y-coordinate of * first scan line of the SU region (applies to eDP v1.4b * and higher). + * - HB2 = 0x6, HB3 = 0x10 + * VSC SDP supporting 3D stereo + Panel Replay. */ return 0; } else if (sdp->sdp_header.HB2 == 0x5 && sdp->sdp_header.HB3 == 0x13) {
