We had tried to add this property during HDMI 2.0 enabling but we realized that it was not mapping to the long term goal of HDR pipeline support. So, to summarize, modeset picks RGB output by default. In case of LSPCON based YCBCR 4:2:0 outputs, we run pipe at YCBCR 4:4:4 config, and then LSPCON scales it down to 4:2:0 sub-sampling, and that's where we need the infrastructure. So in order to support YCBCR 4:4:4 outputs, we need a drm_property which picks user's preference between RGB/YCBCR444. - Shashank</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
