I am currently testing the amdgpu driver with AMD RX460 and RX550
graphics cards on an ARM Cortex-A9 with 1GB RAM and I am consistently
getting deadlocks when playing videos with Kodi or other applications.
I'm using Linux kernel from
https://cgit.freedesktop.org/~agd5f/linux/, branch drm-next-4.16 at
commit "drm/amdgpu: Correct the IB size of bo update mapping" -
104bd2ca1124dfd9aa904d5f5a96253ef2b580f6 along with libdrm-2.4.89 and
mesa-17.3.1 on an Ubuntu 17.10 with Mate desktop and Lightdm session
manager over X11.
I am consistently getting deadlocks, which sometimes are almost
immediate, but sometimes they take about half an hour to occur. There
are some video files that I am using for testing which have more
probability of causing a deadlock than others.
I got some kernel crash dumps, kodi process backtraces for the
offending thread and the deadlocked process tree listing which I
attach here. The kernel seems to deadlock during a page flip,
indefinitelly waiting for the DMA fence to complete, however, it
doesn't and the timeout doesn't expire either... as such this may be a
GPU lockup.
I can provide more details, if needed, if there is interest or time to
look into this.
