Could you set the environment variable R600_DEBUG=ps,vs,gs and post the dumps for both good and bad behavior? This is very strange things Tom. This morning i tried mesa-git 2397a72 & llvm-svn r227384 without success. Now i've tried mesa-git 765cfe9 & llvm-svn r227463 and there is no gpu faults anymore. I'll tried latest llvm-svn ASAP. If you need dumps still i'll do it. But problems are gone for now. Latest mesa&llvm works for me too. I've tried also: unigine-[sanctuary/valley/tropics] & xonotic(and it looks like everything goes faster about ~10%) Unigine-heaven has a problem: "LLVM ERROR: Not supported instr: <MCInst 2210 <MCOperand Reg:3171> <MCOperand Imm:24> <MCOperand Reg:2044> <MCOperand Reg:74>>" But i'll test it again tomorrow. And if things go wrong i'll fill a new bug. thx. |
