<content type='text'>
There is some probability that reset workqueue is blocked by KIQ I/O for 10+ seconds after gpu hangs.
So we need to add a in_reset check during each KIQ register poll.

<title>drm/amdgpu: Remove volatile from CSB functions</title>

<id>d8586afe38984f9eb98d6753c9b1134295d55ceb</id>
<content type='text'>
The CSB buffer manipulation occurs in memory where the BO is mapped
during initialization, and some references to this buffer are handled
with volatile, which is incorrect in this scenario. There are a few
cases where the use of volatile is accepted, but none of them align with
CSB operations. Therefore, this commit removes all the volatile
variables associated with the CSB code.

<title>drm/amdgpu: give each kernel job a unique id</title>

Userspace jobs have drm_file.client_id as a unique identifier
as job's owners. For kernel jobs, we can allocate arbitrary
values - the risk of overlap with userspace ids is small (given
that it's a u64 value).
In the unlikely case the overlap happens, it'll only impact
trace events.

Since this ID is traced in the gpu_scheduler trace events, this
allows to determine the source of each job sent to the hardware.

To make grepping easier, the IDs are defined as they will appear
in the trace output.

Users have reported that they have to reduce the level of undervolting
to acheive stability when dynamic workload profiles are enabled on
GC 10.3.x. Disable dynamic workload profiles if the user has enabled

From GFX6 to GFX11, there is a function for getting the CSB buffer to be
put into the hardware. Three common parts are duplicated in all of these
GFX functions:

1. Prepare the CSB preamble.
2. Parser the CS data.
3. End the CSB preamble.

This commit creates helpers to be used from GFX6 to GFX11.
