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
