- The 2 patch series "squashfs: Remove page->mapping references" from
Matthew Wilcox gets us closer to being able to remove page->mapping.
- The 5 patch series "relayfs: misc changes" from Jason Xing does some
maintenance and minor feature addition work in relayfs.
- The 5 patch series "kdump: crashkernel reservation from CMA" from Jiri
Bohac switches us from static preallocation of the kdump crashkernel's
working memory over to dynamic allocation. So the difficulty of
a-priori estimation of the second kernel's needs is removed and the
first kernel obtains extra memory.
- The 5 patch series "generalize panic_print's dump function to be used
by other kernel parts" from Feng Tang implements some consolidation and
rationalizatio of the various ways in which a faiing kernel splats
information at the operator.

Patch series "relayfs: misc changes", v5.
The series mostly focuses on the error counters which helps every user
debug their own kernel module.
This patch (of 5):
prev_padding represents the unused space of certain subbuffer. If the
content of a call of relay_write() exceeds the limit of the remainder of
this subbuffer, it will skip storing in the rest space and record the
start point as buf->prev_padding in relay_switch_subbuf(). Since the buf
is a per-cpu big buffer, the point of prev_padding as a global value for
the whole buffer instead of a single subbuffer (whose padding info is
stored in buf->padding[]) seems meaningless from the real use cases, so we
don't bother to record it any more.

Future users of intel_de_wait_fw() need the final value. Just return it
for everyone using intel_wait_for_register_fw() and intel_de_wait_fw()
to avoid adding or using another set of specialized functions. There
aren't that many users for these anyway.

There is a rare race condition when preparing for a reset where
guc_lrc_desc_unpin() could be in the process of deregistering a context
while a different thread is scrubbing outstanding contexts and it alters
the context state and does a wakeref put. Then, if there is a failure
with deregister_context(), a second wakeref put could occur. As a result
the wakeref count could drop below 0 and fail an INTEL_WAKEREF_BUG_ON()
check.
Therefore if there is a failure with deregister_context(), undo the
context state changes and do a wakeref put only if the context was set
to be destroyed earlier.

When sending a H2G message where a reply is expected in
guc_submission_send_busy_loop(), outstanding_submission_g2h is
incremented before the send. However, if there is an error sending the
message, outstanding_submission_g2h is decremented without checking if a
reply is expected.
Therefore, check if reply is expected when there is a failure before
decrementing outstanding_submission_g2h.

For newer platforms (post DG2) hardware intentionally stalls on
submisstion of concurrent submissions on RCS and CCS of different
address spaces. With this workaround GuC will never schedule such
conlicting contexts; preventing detection of a stall as a hang.
GuC specs recommend to enable this for all platforms starting from MTL
supporting CCS.
v2: Use existing macros for version check. (Jani)
v3: Reword explanation for clarity. Remove unneeded parens. Remove

Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

hrtimers are initialized with hrtimer_init() and a subsequent store to
the callback pointer. This turned out to be suboptimal for the upcoming
Rust integration and is obviously a silly implementation to begin with.
This cleanup replaces the hrtimer_init(T); T->function = cb; sequence
with hrtimer_setup(T, cb);
The conversion was done with Coccinelle and a few manual fixups.
Once the conversion has completely landed in mainline, hrtimer_init()
will be removed and the hrtimer::function becomes a private member.

(cherry picked from commit 5bea40687c)
Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
When running igt@gem_exec_balancer@individual for multiple iterations,
it is seen that the delta busyness returned by PMU is 0. The issue stems
from a combination of 2 implementation specific details:
1) gt_park is throttling __update_guc_busyness_stats() so that it does
not hog PCI bandwidth for some use cases. (Ref: 59bcdb564b)
2) busyness implementation always returns monotonically increasing
counters. (Ref: cf907f6d29)
If an application queried an engine while it was active,
engine->stats.guc.running is set to true. Following that, if all PM
wakeref's are released, then gt is parked. At this time the throttling
of __update_guc_busyness_stats() may result in a missed update to the
running state of the engine (due to (1) above). This means subsequent
calls to guc_engine_busyness() will think that the engine is still
running and they will keep updating the cached counter (stats->total).
This results in an inflated cached counter.
Later when the application runs a workload and queries for busyness, we
return the cached value since it is larger than the actual value (due to
(2) above)
All subsequent queries will return the same large (inflated) value, so
the application sees a delta busyness of zero.
Fix the issue by resetting the running state of engines each time
intel_guc_busyness_park() is called.

The Balancer and DCC strategies were left off on a fear that
these strategies would conflict with the i915's waitboost.
However, on MTL and Beyond these strategies are only active in
certain conditions where the system is TDP limited.
So, they don't conflict, but help the
waitboost by guaranteeing a bit more of GT frequency.
Without these strategies we were likely leaving some performance
behind on some scenarios.
With this change in place, the enabling/disabling of DCC and Balancer
will now be chosen by GuC, on a platform/GT basis.
v2: - Fix typos and be clear on GuC decision on platform basis (Vinay)
- Limit change to MTL and beyond, where GuC started to take
TDP limit into consideration.
v3: Fix compilation. Actually amend the changes...

On gt reset, if a context is running, then accumulate it's active time
into the busyness counter since there will be no chance for the context
to switch out and update it's run time.

Active busyness of an engine is calculated using gt timestamp and the
context switch in time. While capturing the gt timestamp, it's possible
that the context switches out. This race could result in an active
busyness value that is greater than the actual context runtime value by a
small amount. This leads to a negative delta and throws off busyness
calculations for the user.
If a subsequent count is smaller than the previous one, just return the
previous one, since we expect the busyness to catch up.

On GT reset, we store total busyness counts for all engines and
re-register the utilization buffer with GuC. At that time we should
reset the buffer, so that we don't get spurious busyness counts on
subsequent queries.
To repro this issue, run igt@perf_pmu@busy-hang followed by
igt@perf_pmu@most-busy-idle-check-all for a couple iterations.

All MTL and ARL SKUs share the same GSC FW, but the newer platforms are
only supported in newer blobs. In particular, ARL-S is supported
starting from 102.0.10.1878 (which is already the minimum required
version for ARL in the code), while ARL-H and ARL-U are supported from
102.1.15.1926. Therefore, the driver needs to check which specific ARL
subplatform its running on when verifying that the GSC FW is new enough
for it.

GuC to host communication is interrupt driven, the handling has 3
parts: interrupt context, tasklet and request queue worker.
During GuC reset prepare, interrupt is disabled before destroy
contexts steps start. The IRQ and worker are flushed to finish
any outstanding in-progress message handling. But, the tasklet
flush is missing, it might causes 2 race conditions:
1. Tasklet runs after IRQ flushed, add request to queue after worker
flush started, causes unexpected G2H message request processing,
meanwhile, reset prepare code already get the context destroyed.
This will causes error reported about bad context state.
(https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/11349 and
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12303)
2. Tasklet runs after intel_guc_submission_reset_prepare,
ct_try_receive_message start to run, while intel_uc_reset_prepare
already finished guc sanitize and set ct->enable to false. This will
causes warning on incorrect ct->enable state.
(https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12439)
Add the missing tasklet flush to flush all 3 parts.
