17:06 melissawen: hey, I'm examining dpp_color_caps again and I'm a bit confused by this degamma ROM transfer function: `dc->caps.color.dpp.dgam_rom_caps.bt2020 = 1;`
17:07 melissawen: I don't see the usage of this hardcoded curve anywhere in the display driver code
17:07 melissawen: on the other hand, I see BT709 transfer function, but no mentions in dgam_rom_caps
17:09 melissawen: Is it deprecated or mistakenly named?
17:10 melissawen: hwentlan_, siqueira_ ^ any idea?
17:19 siqueira: melissawen I guess this is something we planned to use, but we never implemented it. It is probably safe to drop this cap.
17:22 melissawen: siqueira, I see, thanks!
17:23 melissawen: but how about BT709, is there a hardcoded curve for this pre=defined transfer function?
17:23 melissawen: I mean, degamma BT709 ROM support?
17:58 melissawen: for the BT709 question, nvm. For dcn3, I found we don't check color_caps, we just set it directly in dpp3_set_pre_degam()
