Both error-capture and relay-logging mechanism use the GuC
log infrastructure. That means the KMD must send a log flush
complete notification back to GuC after reading the data out.
This call is currently being sent synchronously.
However, synchronous H2Gs cause problems when the system is
backed up. There is no need for this to be synchronous. The
KMD wasn't even looking at the return status from it. So make
it asynchronous and then there is no issue about time outs.

- 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 i915_gpu_codedump, duplicate global and engine-class register
lists for each engine-instance register dump if we find
dependent-engine resets in a engine-capture-group.
- When i915_gpu_coredump calls into capture_engine, (in a
subsequent patch) we detach the matching node (guc-id,
LRCA, etc) from the link list above and attach it to
i915_gpu_coredump's intel_engine_coredump structure when have
matching LRCA/guc-id/engine-instance.
Additional notes to be aware of:
- GuC generates the error capture dump into the GuC log buffer but
this buffer is one big log buffer with 3 independent subregions
within it. Each subregion is populated with different content
and used in different ways and timings but all regions operate
behave as independent ring buffers. Each guc-log subregion
(general-logs, crash-dump and error- capture) has it's own
guc_log_buffer_state that contain independent read and write
pointers.

GuC log buffer regions for debug-log-events, crash-dumps and
error-state-capture are all part of a single bo allocation that
also includes the guc_log_buffer_state structures. Now that we
support it, increase the size allocation for error-capture.
Since the error-capture region is accessed at non-deterministic
times (as part of GuC triggered context reset) while debug-log-
events region is accessed as part of relay logging or during
debugfs triggered dumps, move the mapping and unmapping of the
shared buffer into intel_guc_log_create and intel_guc_log_destroy
so that it's always mapped throughout life of GuC operation.
Additionally, while here, update the guc log region layout
diagram to follow the order according to the enum definition
as per the GuC interface.
NOTE: A future effort to visit (part of baseline code) is that
buf_addr should be updated to be a io_sys_map and use the
io_sys_map wrapper functions to access the various GuC log
buffer regions.

[Fixed conflicts while applying, using the fixups/drm-intel-gt-next.patch
from drm-rerere's 1f2b1742abdd ("2022y-02m-23d-16h-07m-57s UTC: drm-tip
rerere cache update")]
Update to the latest GuC release.
The latest GuC firmware introduces a number of interface changes:
GuC may return NO_RESPONSE_RETRY message for requests sent over CTB.
Add support for this reply and try resending the request again as a
new CTB message.
A KLV (key-length-value) mechanism is now used for passing
configuration data such as CTB management.
With the new KLV scheme, the old CTB management actions are no longer
used and are removed.
Register capture on hang is now supported by GuC. Full i915 support
for this will be added by a later patch. A minimum support of
providing capture memory and register lists is required though, so add
that in.
The device id of the current platform needs to be provided at init time.
The 'poll CS' w/a (Wa_22012773006) was blanket enabled by previous
versions of GuC. It must now be explicitly requested by the KMD. So,
add in the code to turn it on when relevant.
The GuC log entry format has changed. This requires adding a new field
to the log header structure to mark the wrap point at the end of the
buffer (as the buffer size is no longer a multiple of the log entry
size).
New CTB notification messages are now sent for some things that were
previously only sent via MMIO notifications.
Of these, the crash dump notification was not really being handled by
i915. It called the log flush code but that only flushed the regular
debug log and then only if relay logging was enabled. So just report
an error message instead.
The 'exception' notification was just being ignored completely. So add
an error message for that as well.
Note that in either the crash dump or the exception case, the GuC is
basically dead. The KMD will detect this via the heartbeat and trigger
both an error log (which will include the crash dump as part of the
GuC log) and a GT reset. So no other processing is really required.

Start using device specific parameters instead of module parameters for
most things. The module parameters become the immutable initial values
for i915 parameters. The device specific parameters in i915->params
start life as a copy of i915_modparams. Any later changes are only
reflected in the debugfs.
The stragglers are:
* i915.force_probe and i915.modeset. Needed before dev_priv is
available. This is fine because the parameters are read-only and never
modified.
* i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and
I915_STATE_WARN_ON would result in massive and ugly churn. This is
handled by not exposing the parameter via debugfs, and leaving the
parameter writable in sysfs. This may be fixed up in follow-up work.
* i915.inject_probe_failure. Only makes sense in terms of the module,
not the device. This is handled by not exposing the parameter via
debugfs.
