Pull drm updates from Dave Airlie:
"There are two external interactions of note, the msm tree pull in some
opp tree, hopefully the opp tree arrives from the same git tree
however it normally does.

There is also a new cgroup controller for device memory, that is used
by drm, so is merging through my tree. This will hopefully help open
up gpu cgroup usage a bit more and move us forward.

There is a new accelerator driver for the AMD XDNA Ryzen AI NPUs.

Then the usual xe/amdgpu/i915/msm leaders and lots of changes and
refactors across the board:

This removes duplicate register definitions across manual-capture vs
guc-err-capture.

drm/xe/guc: Plumb GuC-capture into dev coredump

When we decide to kill a job, (from guc_exec_queue_timedout_job), we could
end up with 4 possible scenarios at this starting point of this decision:
1. the guc-captured register-dump is already there.
2. the driver is wedged.mode > 1, so GuC-engine-reset / GuC-err-capture
will not happen.
3. the user has started the driver in execlist-submission mode.
4. the guc-captured register-dump is not ready yet so we force GuC to kill
that context now, but:
A. we don't know yet if GuC will be successful on the engine-reset
and get the guc-err-capture, else kmd will do a manual reset later
OR B. guc will be successful and we will get a guc-err-capture
shortly.

So to accomdate the scenarios of 2 and 4A, we will need to do a manual KMD
capture first(which is not be reliable in guc-submission mode) and decide
later if we need to use that for the cases of 2 or 4A. So this flow is
part of the implementation for this patch.

Provide xe_guc_capture_get_reg_desc_list to get the register dscriptor
list.
Add manual capture by read from hw engine if GuC capture is not ready.
If it becomes ready at later time, GuC sourced data will be used.

Although there may only be a small delay between (1) the check for whether
guc-err-capture is available at the start of guc_exec_queue_timedout_job
and (2) the decision on using a valid guc-err-capture or manual-capture,
lets not take any chances and lock the matching node down so it doesn't
get re-claimed if GuC-Err-Capture subsystem is running out of pre-cached
nodes.

drm/xe/guc: Extract GuC error capture lists

Upon the G2H Notify-Err-Capture event, parse through the
GuC Log Buffer (error-capture-subregion) and generate one or
more capture-nodes. A single node represents a single "engine-
instance-capture-dump" and contains at least 3 register lists:
global, engine-class and engine-instance. An internal link
list is maintained to store one or more nodes.

Because the link-list node generation happen before the call
to devcoredump, duplicate global and engine-class register
lists for each engine-instance register dump if we find
dependent-engine resets in a engine-capture-group.

To avoid dynamically allocate the output nodes during gt reset,
pre-allocate a fixed number of empty nodes up front (at the
time of ADS registration) that we can consume from or return to
an internal cached list of nodes.

drm/xe/guc: Prepare GuC register list and update ADS size for error capture

Add referenced registers defines and list of registers.
Update GuC ADS size allocation to include space for
the lists of error state capture register descriptors.

Then, populate GuC ADS with the lists of registers we want
GuC to report back to host on engine reset events. This list
should include global, engine-class and engine-instance
registers for every engine-class type on the current hardware.

Ensure we allocate a persistent storage for the register lists
that are populated into ADS so that we don't need to allocate
memory during GT resets when GuC is reloaded and ADS population
happens again.
