--- Comment #2 from Benji Wiebe  ---
New backtrace with debugging turned on. It appears that the issue is a NULL
pointer dereference in r600_resource_copy_region (dst). In
compute_memory_promote_item, pool->bo is NULL (which is what 'dst' is for
r600_resource_copy_region).

[Bug 102595] clpeak

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=102595

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@lists.freedesktop.org
  Reporter: benjiwieb...@gmail.com
QA Contact: dri-devel@lists.freedesktop.org

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

[benji@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 7f3d77e5a42a sp
7fff93152570 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.
