    Wait, is it "zeroing" or "zering"?

      This just refactors stuff to make it easier to enable it on select buffers in RADV internally. The ability to zero buffers in VRAM (for e.g. game workarounds) has existed in radv for 1+ years (RADV_DEBUG=zerovram).

        making things easier to debug is always good!

          Is AMD going to implement eGPU unplug? I find it rather problematic that attaching Type-C cable from eGPU dock couple of times cause hard lockup.

            Oh, so, we would not see trash on screen with gnome on wayland when new window is created but yet to be redrawn by application. That is nice.

              Annoying how the drivers need to build workarounds for these buggy apps.

                There will always be buggy and poorly written apps, but we always want the user experience to be as good as possible, so driver work arounds are a necessary evil
