I made small fix for Mesa3D that fixes segfault on PPS Sieve OpenCL application:

file 'gallium/drivers/radeon/r600_pipe_common.c' (at r600_disk_cache_create function):

if (disk_cache_get_function_timestamp(LLVMInitializeAMDGPUTargetInfo, &llvm_timestamp)) { /*res = asprintf(&timestamp_str, "%u_%u", mesa_timestamp, llvm_timestamp);*/ timestamp_str = malloc(100); sprintf(timestamp_str, "%u_%u", mesa_timestamp, llvm_timestamp); }


diff:
diff --git a/src/gallium/drivers/radeon/r600_pipe_common.c b/src/gallium/drivers/radeon/r600_pipe_common.c index b77d85901f..40c713a422 100644 --- a/src/gallium/drivers/radeon/r600_pipe_common.c +++ b/src/gallium/drivers/radeon/r600_pipe_common.c @@ -914,7 +914,10 @@ static void r600_disk_cache_create(struct r600_common_screen *rscreen) if (disk_cache_get_function_timestamp(LLVMInitializeAMDGPUTargetInfo, &llvm_timestamp)) { - res = asprintf(&timestamp_str, "%u_%u", + /*res = asprintf(&timestamp_str, "%u_%u", + mesa_timestamp, llvm_timestamp);*/ + timestamp_str = malloc(100); + sprintf(timestamp_str, "%u_%u", mesa_timestamp, llvm_timestamp); }


works good on my RX 480 and RX VEGA (but slower than on propietary AMD OpenCL drivers).

All what your patch does is leaving "res" uninitialized. Most probably code below will change behavior due to different (or random) value of "res".

That's not saying that your segfaults won't return. It can be difficult to pinpoint the cause.

I was getting segfaults on GFN at the end of a run when messing with source code, which then continued to happen with normal production binaries. That was pretty jarring until I found that the genefer.dat benchmarks file was for the wrong set of transforms as a result of my experimentation. Once I realized this, the problem was solved trivially by deleting the genefer.dat file and letting the program recreate it from scratch.

Oh, no. actually, i was omitting res value. but was initialized, so wrong patch disables disk cache for shaders.
new corrected path (in file 'gallium/drivers/radeon/r600_pipe_common.c' (at r600_disk_cache_create function):

/*res = asprintf(&timestamp_str, "%u_%u", mesa_timestamp, llvm_timestamp);*/ timestamp_str = malloc(100); res = sprintf(timestamp_str, "%u_%u", mesa_timestamp, llvm_timestamp);

Stupid question: Can I fix my the first post in this thread? Or, can anyone fix that stupid bug in first post? I can't find option edit my first post.

You can only edit a post for the first 15 minutes after it's posted. After that just post a new message with revisions.
