<pre>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
<a href="https://patchwork.freedesktop.org/patch/258005/">https://patchwork.freedesktop.org/patch/258005/</a>
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</pre>
