            Bug ID: 111332
           Summary: Long running application causes assert in amdgpu_bo.c
                    'bo->cpu_map_count > 0' failed
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: freedesktop@harrisonconsoles.com

We have an OpenGL application that runs 24/7. After 4-5 days the application
quits with this error in the syslog.

../amdgpu/amdgpu_bo.c:443: amdgpu_bo_cpu_map: Assertion `bo->cpu_map_count > 0'
failed.

The system is running
Debian 10 buster (kernel 4.19.0)
libdrm 2.4.99 built from source (gitlab.freedesktop.org)

There seems to be a patch to fix this problem here
https://patchwork.freedesktop.org/patch/258005/

But there has been no activity on this patch in a while and it has not been
merged.

I will start a test of this patch and will verify if it works for me, but it
will take 5 days to confirm.

Any chance of getting this patch merged?

Thanks,
Todd

As discussed there, this is a Mesa issue and should be addressed there.

I can't comment on where the fix should be, but

1. This does not happen on a radeon based system

2. With the patch applied to the amdgpu code the application has been running
for over 7 days now with no issues.
