Does that avoid > the problem? More testing - incomplete but will post initial findings as I don't know when I'll finish. I managed to get older mesa to build with new llvm by applying the build fixes. With mesa on the commit before r600g,radeonsi: Set RADEON_GEM_NO_CPU_ACCESS flag for tiled BOs (I don't know yet exactly what mesa commit changed things) I can with your patch or the stream revert get "good" behavior, this was with a kernel on the "bad" HPD kernel commit. Will test more over time. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
