    Phoronix: Radeon RADV Driver Lands Vulkan Mesh Shader Support

    Being merged a few minutes ago into Mesa 22.3 is the Radeon Vulkan driver "RADV" support for the recently ratified mesh shader extension...

    Mesh shaders work great here on my NAVI22 6800M with the new GravityMark benchmark

    Unfortunately things look blocky with Ray Tracing and CS (Computer Shader?), the later is a newly added mode to this version of GravityMark, it looks even worse in GL mode

    Bug report here: https://gitlab.freedesktop.org/mesa/mesa/-/issues/6410

      I dont know about you but for me as non-native speaker "gang submit" sounds weirdly naughty. Is there some underlying pun intended?

          In a nutshell: it means that instead of just submitting command buffers to a single queue, you submit a "gang" of command buffers to multiple queues at a time. The "gang leader" is the last command buffer and it determines which queue's fences should be signaled.

          This guarantees that they can't get mixed up with similar submits from other processes.
