            Bug ID: 102595
           Summary: clpeak
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: benjiwiebe14 at gmail.com
        QA Contact: dri-devel at lists.freedesktop.org

When I run 'clpeak --global-bandwidth' I get:

[benji at benji-pc clpeak]$ ./clpeak --global-bandwidth

Platform: Clover
  Device: AMD CAYMAN (DRM 2.50.0 / 4.13.0+, LLVM 6.0.0)
    Driver version  : 17.3.0-devel (Linux x64)
    Compute units   : 12
    Clock frequency : 880 MHz

    Global memory bandwidth (GBPS)
      float   : radeon: Failed to allocate a buffer:
radeon:    size      : 1073741824 bytes
radeon:    alignment : 4096 bytes
radeon:    domains   : 4
radeon:    flags     : 4
radeon: Failed to allocate a buffer:
radeon:    size      : 1073741824 bytes
radeon:    alignment : 4096 bytes
radeon:    domains   : 4
radeon:    flags     : 4
Segmentation fault (core dumped)



And in dmesg:
[55959.960796] clpeak[16731]: segfault at 1c ip 00007f3d77e5a42a sp
00007fff93152570 error 4 in pipe_r600.so[7f3d77d53000+1c2000]


The clpeak compute-* and kernel-latency tests work fine, and transfer-bandwidth
fails with a (I believe) unrelated error message, seemingly due to me running
Linux-git.
