Created attachment 143890 [details] desktop artifacting after doom crash Got a shiny new Vega VII, was running some tests on mesa-git + llvm-git. Managed to get a fun game crash with DOOM 2016 in Vulkan that causes the GPU to artifact on all desktops. Restarting the system makes it go back to normal. This only happens on mesa-git + llvm-svn, does not happen on Mesa 19.0.1 + LLVM 8 System: Fedora 30 Kernel 5.0.7 Threadripper 2920x Radeon Vega VII Broken: Mesa-git + LLVM-git Working: Mesa 19.0.1 + LLVM 8.0.0
Can you explain the steps for reproducing the problem in-game?
Sure, I just started a new campaign and loaded into the first mission. no less than about 15-30 seconds in it immediately went black/polygony, then crashed. I'll see if I can record it later tonight. My resolution was 4k60 and settings were maxed
https://youtu.be/9dtlKTMGqTE game didn't crash this time, and at least i was able to capture it
Does it render correctly with Mesa-git + LLVM 8.0.0 ?
Could be something specific to Vega20 as it renders correctly for me on Vega10+mesa-git+llvm-git.
Issue does -not- occur on mesa-git + llvm 8, so looks like it's an llvm issue
Can you eventually bisect? Unfortunately, I don't have a Vega20.
Got a Vega20, I tried to reproduce the problem with mesa-git, llvm-git and the same settings as you, but it doesn't happen. I also tried some older LLVM commits, no graphic glitches so far. Are you still able to reproduce the problem?
could you try reverting: https://github.com/mesa3d/mesa/commit/b5ea4378c3260ff003532c8138a81a57091bdaa0#diff-078b981b454c93e62531f44768fca61d ac/nir: only use the new raw/struct image atomic intrinsics with LLVM 9+ b5ea4378c3260ff003532c8138a81a57091bdaa0 and see if this fixes your issue?
Hi all, sorry for such a long delay on this. I recently switched to Fedora and realized the llvm build from the copr repo I was using was over a month old. I needed some time to create my own repos to circumvent this problem. As of today I've tested with llvm-git + mesa-git built yesterday and everything is working as it should. Please feel free to close the ticket as the issue has been resolved with an updated llvm build.
Thanks for confirming!
