    Phoronix: 34 More Patches Roll Out For AMDGPU DC With Raven Ridge Fixes Plus Color Management

    Open-source AMD Linux driver developers have started off the week by posting 34 more patches for the "DC" display code stack that was mainlined in Linux 4.15 and further improved with Linux 4.16. With these latest patches that begin the queue for Linux 4.17 there are yet more AMDGPU DC improvements and in particular Raven Ridge fixes...

    FWIW, amdgpu has always supported the legacy LUTs for color correction. This just introduces the new regamma/gamma/CTM interfaces for newer hw features.

      So how long do we have to wait before we "really" get DC rather than just a few more bits here and there? Is there any summary website or mailing list message showing an overview of which bits and pieces will be in various versions of the kernel?

        Does anybody know the reason behind why GCN 1 can't get AMDGPU DC? Is it a hardware limitation?

          It could be done. It's just a lot of work.

              Why would we need DC on GCN1.0? It's working perfectly.

                Thanks for the link!

                i need to ask though, is there a distro out there that is supporting Raven Ridge mobile installs out of the box? So far ive tried a few with no positive results.

                Ultimately i want to install to the internal drive but i need confidence that we are past the alpha state as far as support goes in Linux.

                  You could try my distribution, if it is not working with Raven let us make it work: https://www.youtube.com/watch?v=fKJ-IatUfis

                  Copy it to a usb memory stick and install it to another usb memory stick. This way your main drive is not touched.
