            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

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.

without X

Thanks to a tip from tom stellard I tried it without X (after exiting sddm). 

I've tried to start the miner with "real work" from a pool as recommended:

GPU_FORCE_64BIT_PTR=0 GPU_MAX_HEAP_SIZE=100 GPU_USE_SYNC_OBJECTS=1
GPU_MAX_ALLOC_PERCENT=100 GPU_SINGLE_ALLOC_PERCENT=100 ./ethminer
--farm-recheck 200 -G -S eu1.ethermine.org:4444 etc. etc.

I get gpu faults, but no hangs or other issues and the system is usable
normally after exiting the miner.

The -G --benchmark mode still has worse troubles with hangs etc.
