<content type='text'>
The correct fix is to tie the global xa entry lifetime to the
queue lifetime: insert in amdgpu_userq_create() and erase in
amdgpu_userq_cleanup(), both at the well-defined doorbell_index key,
making the operation O(1) and resolve the fence driver UAF problem
by binding the userq driver fence to per queue.

v2: clean up the local variables initialization. (Christian)

<title>drm/amdgpu: move devcoredump generation to a worker</title>

<id>4bbba79a7f1d0c7296bf8c935d65a9ff633f6917</id>
<content type='text'>
Update the way drm_coredump_printer is used based on its documentation
and Xe's code: the main idea is to generate the final version in one go
and then use memcpy to return the chunks requested by the caller of
amdgpu_devcoredump_read.

The generation is moved to a separate worker thread.

This cuts the time to copy the dump from 40s to ~0s on my machine.

---
v3:
- removed adev-&gt;coredump_in_progress and instead use work as
  the synchronisation mechanism
- use kvfree instead of kfree
