wlr-gamma-control protocol
Are there any plans to support wlr-gamma-control?
No plans atm. Kernel Apis for color management are currently in flux. I believe this might be possible as part of the work for the color management protocol.
Could this be implemented now after the work done on the color management protocol? (Sorry for being annoying lol)
The only relation is that the VK_EXT_descriptor_buffer code might make it slightly easier to implement if it were to be done via emulation in a shader. But it's not much.
However, you really want to implement it via the CRTC connector properties. Currently there is GAMMA_LUT which can be used for this functionality. But this property will be deprecated with the new kernel APIs and it would not work if the output is configured to use HDR10.
