    Phoronix: AMD Readies New Radeon Driver Code For Linux 5.17: STB, Seamless Boot For Van Gogh

    Along with Intel this week sending out some of their initial graphics driver changes destined for the Linux 5.17 cycle early next year, AMD today also submitted their first batch of AMDGPU DRM driver changes intended for this next kernel version...

    Flicker-free boot on AMD? Finally!
    Now if only that feature was available on their dedicated graphics cards...

      For quite a few kernel versions already I get this weird effect when during boot the font (in the framebuffer?) is first really big, then it turns small as it should be and stays that way. Not a deal breaker for anything, but slightly annoying that it regressed.

      (RX 6800 XT / DP / 2560x1440 / 144 Hz) .

          Is this for HDR?

          I believe amd's driver stack didn't know how to deal with FALD and Oled backlights, hence why there are no freesync-premium-pro monitors with anything more than small-number edge-lit backlights.

            I have another issue with the frame buffer during boot. Between rEfind (or grub) and GDM, the screen gets a number of vertical flickering "stacks" of various heights.
            I haven't gotten around to logging a bug for it. I recently got a 6700 XT, after buying a 5120x1440 UltraWide curved screen, and it only happens when running the screen at that resolution. If I split the screen into two, treating it as two separate screens, the issue doesn't show up.

            I need to gather the energy to log a bug.

              I hope they can make those Van Gogh APUs work right. I was looking on the internet and they produce very bad quality graphics:

                OLED doesn't have a back light it has surface lighting.

                Does any one know if VG is actually in the wild yet beyond a few steam decks that youtubers got to fondle?

                  I wouldn't hold my hopes up. I doubt AMD engineers can implement something like this, either on dedicated or integrated GPUs.
                  They can advertise it, but it will never work. Just look at OpenCL.

                    fald is a scam which distorts your image to game metrics
