HDR functionality in weston 12

[Namit Solanki (QUIC)]

Hi,

I have certain questions for HDR functionality in Weston 12, please help me


  1.  Drm-backend can read 3D LUT and 1d LUT for each plane?
  2.  HDR meta data is read from wayland app and is being sent to display 
driver as connector property?
  3.  If planes are capable for tonemapping, tonemapping from planes are 
supported?
  4.  I think below code is dead code, please correct me if I am wrong, please 
let me know the reason for same (in backend-drm, file kms.c function 
drm_output_apply_state_atomic())

                        if (!output->deprecated_gamma_is_set) {

                                    ret |= crtc_add_prop_zero_ok(req, crtc,

                                                                             
WDRM_CRTC_GAMMA_LUT, 0);

                                    ret |= crtc_add_prop_zero_ok(req, crtc,

                                                                             
WDRM_CRTC_DEGAMMA_LUT, 0);

                        }


Thanks
Namit
