Bug ID: 101584 Summary: clover: ethminer -G --benchmark: ring buffer overflow, GPU faults Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: haagch@frickel.club QA Contact: dri-devel@lists.freedesktop.org
Created attachment 132229 --> https://bugs.freedesktop.org/attachment.cgi?id=132229&action=edit dmesg
Tested with my RX 480 on mesa git and Linux 4.11 and 4.12-rc.
To reproduce, get https://github.com/ethereum-mining/ethminer in libethash-cl/ethash_cl_miner_kernel.cl add #pragma OPENCL EXTENSION cl_clang_storage_class_specifiers : enable then cmake . and make and in ethminer/ run ./ethminer -G --benchmark
it outputs some progress and at 97% something goes wrong and I get GPU faults and/or GPU hangs.
Interestingly with the closed source OpenCL runtime from amdgpu-pro it fails at 97% too.
