Description Samuel Pitoiset 2019-04-19 14:05:07 UTC
No Man Sky hangs with mesa-git, it works fine with Mesa 19.0.1 or 19.0.2.

Created attachment 144046 [details] [review] workaround This fixes the GPU hang. The split_alu_of_phi NIR pass seems correct to me. The generated NIR and LLVM IR (for the shader that hangs) also seem correct to me, so this likely triggers a bug in LLVM.

For me the game hangs as well (Radeon VII, Mesa 19.0.3), but it's not a GPU hang as I can tab out and clsoe the game. Will try that fix and report back
Comment 4 Benedikt 2019-05-05 12:00:27 UTC
oh, this may be a different thing - I am trying the Vulkan branch - doh! Sorry about the confusion

That workaround works for me but has huge graphical artifacts. Like blue triangles all over the screen. Basically unplayable.
Comment 6 Haxk20 2019-08-14 18:04:13 UTC
This is issue of ACO and not mesa in general. But UI is still unusable. Like 5 fps UI.
Comment 7 Samuel Pitoiset 2019-08-20 12:00:57 UTC
Since the last update of No Man Sky, the game no longer hangs with RADV. The old issue probably still remains in LLVM but it got "fixed" by the game itself. As for the other issues, we are working on. Closing this ticket as it refers to an old GPU hang.
