    Phoronix: AMD Has A Number Of Graphics Driver Fixes To Add For Linux 5.4

    In addition to the new hardware support and other features queued already in DRM-Next for the upcoming Linux 5.4 merge window, on Friday AMD sent in a final pull request to DRM-Next of new material ahead of this upcoming kernel cycle...

    There is also scatter gather support for Raven APUs. Fixing the tearing. Still need to test if it works correctly but its there.

      APU with vRAM huh, most AMD APUs just use system ram. this might be a decent performer with its own dedicated memory

        Having issues with black screen on my 5700. I really hope they fix it...

        Moment amdgpu gets loaded = black screen. Until its loaded I have console only. Probably I can use VESA, but its not a solution, its getting autoloaded by distro.(hence I use older kernel version, where there is no AMDGPU for Navi)

          Are you sure it's an AMD specific issue? I had that same behavior on an old evergreen card recently, and it turns out I had disabled legacy FB Console emulation in the drm subsystem configs in the kernel on the machine I was on.

            I did not disable anything. I only changed from GTX780ti to 5700XT. I can see console is starting up after grub starts kernel, for a second i see kernel messages and BOOM. i can hear sound card makes tick(alsa driver loaded in) and screen goes dead, as I suspect AMDGPU driver loaded.

            if you look at link I gave, it will have a lot more info.

              I had a similar issue. Make sure you have the recent firmware in /lib/firmware/amdgpu from here:

                The navi fixes should go into 5.3 - why is it ok to release 5.3 with buggy navi support?

                  I am positively sure of it. My console works for a few seconds. I don't have Xorg/GUI autostart. I can see kernel boot messages for one second(nvme ssd, system loads in like 3 seconds, no exaggeration, and I probably make mistake on side of modesty, i give it second or half). After which systemd loads amdgpu. And i have black screen. Machine is not locked. I can get dmesg output from SSH and lsmod. Both confirm driver is loaded.

                  As per my link to kernel bugzilla, there is a lot more info if you care to help linuxoid in need

                    amdgpu was configured as module, so my understanding is that I don't need to put individual firmware file names into .config file, since they will be autodetected at module loading time.
