In commit 0b639decf6 ("scsi: pm8001: Modify task abort handling for SATA
task"), code was introduced to dereference "task" pointer in
pm8001_abort_task(). However there was a pre-existing later check for
"!task", which spooked the kernel test robot.
Function pm8001_abort_task() should never be passed NULL for "task"
pointer, so remove that check. Also remove the "unlikely" hint, as this is
not fastpath code.

With the introduction of the delayed disable-sched behavior,
we use the GuC's xarray of valid guc-id's as a way to
identify if new requests had been added to a context
when the said context is being checked for closure.
Additionally that prior change also closes the race for when
a new incoming request fails to cancel the pending
delayed disable-sched worker.
With these two complementary checks, we see no more

Add a delay, configurable via debugfs (default 34ms), to disable
scheduling of a context after the pin count goes to zero. Disable
scheduling is a costly operation as it requires synchronizing with
the GuC. So the idea is that a delay allows the user to resubmit
something before doing this operation. This delay is only done if
the context isn't closed and less than a given threshold
(default is 3/4) of the guc_ids are in use.
Alan Previn: Matt Brost first introduced this patch back in Oct 2021.
However no real world workload with measured performance impact was
available to prove the intended results. Today, this series is being
republished in response to a real world workload that benefited greatly
from it along with measured performance improvement.
Workload description: 36 containers were created on a DG2 device where
each container was performing a combination of 720p 3d game rendering
and 30fps video encoding. The workload density was configured in a way
that guaranteed each container to ALWAYS be able to render and
encode no less than 30fps with a predefined maximum render + encode
latency time. That means the totality of all 36 containers and their
workloads were not saturating the engines to their max (in order to
maintain just enough headrooom to meet the min fps and max latencies
of incoming container submissions).
Problem statement: It was observed that the CPU core processing the i915
soft IRQ work was experiencing severe load. Using tracelogs and an
instrumentation patch to count specific i915 IRQ events, it was confirmed
that the majority of the CPU cycles were caused by the
gen11_other_irq_handler() -> guc_irq_handler() code path. The vast
majority of the cycles was determined to be processing a specific G2H
IRQ: i.e. INTEL_GUC_ACTION_SCHED_CONTEXT_MODE_DONE. These IRQs are sent
by GuC in response to i915 KMD sending H2G requests:
INTEL_GUC_ACTION_SCHED_CONTEXT_MODE_SET. Those H2G requests are sent
whenever a context goes idle so that we can unpin the context from GuC.
The high CPU utilization % symptom was limiting density scaling.
Root Cause Analysis: Because the incoming execution buffers were spread
across 36 different containers (each with multiple contexts) but the
system in totality was NOT saturated to the max, it was assumed that each
context was constantly idling between submissions. This was causing
a thrashing of unpinning contexts from GuC at one moment, followed quickly
by repinning them due to incoming workload the very next moment. These
event-pairs were being triggered across multiple contexts per container,
across all containers at the rate of > 30 times per sec per context.
Metrics: When running this workload without this patch, we measured an
average of ~69K INTEL_GUC_ACTION_SCHED_CONTEXT_MODE_DONE events every 10
seconds or ~10 million times over ~25+ mins. With this patch, the count
reduced to ~480 every 10 seconds or about ~28K over ~10 mins. The
improvement observed is ~99% for the average counts per 10 seconds.
Design awareness: Selftest impact.
As temporary WA disable this feature for the selftests. Selftests are
very timing sensitive and any change in timing can cause failure. A
follow up patch will fixup the selftests to understand this delay.
Design awareness: Race between guc_request_alloc and guc_context_close.
If a context close is issued while there is a request submission in
flight and a delayed schedule disable is pending, guc_context_close
and guc_request_alloc will race to cancel the delayed disable.
To close the race, make sure that guc_request_alloc waits for
guc_context_close to finish running before checking any state.
Design awareness: GT Reset event.
If a gt reset is triggered, as preparation steps, add an additional step
to ensure all contexts that have a pending delay-disable-schedule task
be flushed of it. Move them directly into the closed state after cancelling
the worker. This is okay because the existing flow flushes all
yet-to-arrive G2H's dropping them anyway.

During GuC error capture initialization, we estimate the amount of size
we need for the error-capture-region of the shared GuC-log-buffer.
This calculation was incorrect so fix that. With the fixed calculation
we can reduce the allocation of error-capture region from 4MB to 1MB
(see note2 below for reasoning). Additionally, switch from drm_notice to
drm_debug for the 3X spare size check since that would be impossible to
hit without redesigning gpu_coredump framework to hold multiple captures.
NOTE1: Even for 1x the min size estimation case, actually running out
of space is a corner case because it can only occur if all engine
instances get reset all at once and i915 isn't able extract the capture
data fast enough within G2H handler worker.
NOTE2: With the corrected calculation, a DG2 part required ~77K and a PVC
required ~115K (1X min-est-size that is calculated as one-shot all-engine-
reset scenario).

Driver had discrepancy in how cdclk squash and crawl support
were checked. Like crawl, add squash as a 1 bit feature flag
to the display section of DG2.

These PMICs all contain a GPIO controller. Now that the binding for this
variant is documented, wire up the controller in the device tree.

The "ldo-io0" and "ldo-io1" regulators are enabled/disabled by toggling
the pinmux between two functions. This happens in the regulator driver.
Setting the pinmux to "ldo" in the DT is inappropriate because it would
enable the regulator before the driver has a chance to set the correct
initial voltage.

xfs_rename can update up to 5 inodes: src_dp, target_dp, src_ip, target_ip
and wip. So we need to increase the inode reservation to match.

Waitboost (when SLPC is enabled) results in a H2G message. This can result
in thousands of messages during a stress test and fill up an already full
CTB. There is no need to request for boost if min softlimit is equal or
greater than it.
v2: Add the tracing back, and check requested freq
in the worker thread (Tvrtko)
v3: Check requested freq in dec_waiters as well
v4: Only check min_softlimit against boost_freq. Limit this
optimization for server parts for now.
v5: min_softlimit can be greater than boost (Ashutosh)

This is the part1 of my HDaudio cleanups, before the addition of
to-be-announced HDaudio extensions.
The patchset includes more consistent use of read/write/update
helpers, removal of useless waits, structure members and programming
sequences, removal of confusing sharing of private_data between FE and
BE.
Additional patches are coming to split the controller, codec and
multi-link management functionality in well-identified files.
Pierre-Louis Bossart (16):
ASoC: SOF: ops: fallback to mmio in helpers
ASoC: SOF: Intel: use mmio fallback for all platforms
ASoC: SOF: ops: add readb/writeb helpers
ASoC: SOF: ops: add snd_sof_dsp_updateb() helper
ASoC: SOF: Intel: hda-dsp: use SOF helpers for consistency
ASoC: SOF: Intel: hda-dai: start removing the use of
runtime->private_data in BE

ASoC: SOF: Intel: hda-ctrl: remove useless sleep
ASoC: SOF: Intel: hda: always do a full reset
ASoC: SOF: Intel: hda: remove useless check on GCTL
ASoC: SOF: Intel: hda-stream: use SOF helpers for consistency
ASoC: SOF: Intel: hda-stream: rename CL_SD_CTL registers as SD_CTL
ASoC: SOF: Intel: hda: use SOF helper for consistency

Merge series from Aidan MacDonald <aidanmacdonald.0x0@gmail.com>:
This series is a preparatory cleanup of the jz4740-i2s driver before
adding support for a new SoC. The two improvements are lifting
unnecessary restrictions on sample rates and formats -- the existing
ones appear to be derived from the limitations of the JZ4740's internal
codec and don't reflect the actual capabilities of the I2S controller.
I'm unable to test the series on any JZ47xx SoCs, but I have tested
on an X1000 (which is the SoC I'll be adding in a followup series).

The selftests/bpf/test_bpftool_synctypes.py runs checking in the above.
The failure is introduced by Commit c4bcfb38a95e("bpf: Implement cgroup storage available
to non-cgroup-attached bpf progs"). The commit introduced BPF_MAP_TYPE_CGROUP_STORAGE_DEPRECATED
which has the same enum value as BPF_MAP_TYPE_CGROUP_STORAGE.
In test_bpftool_synctypes.py, one test is to compare uapi bpf.h map types and
bpftool supported maps. The tool picks 'cgroup_storage_deprecated' from bpf.h
while bpftool supported map is displayed as 'cgroup_storage'. The test failure
can be fixed by explicitly replacing 'cgroup_storage_deprecated' with 'cgroup_storage'
in uapi bpf.h map types.

The gadget driver may have a certain expectation of how the request
completion flow should be from to its configuration. Make sure the
controller driver respect that. That is, don't set IMI (Interrupt on
Missed Isoc) when usb_request->no_interrupt is set. Also, the driver
should only set IMI to the last TRB of a chain.

When servicing a transfer completion event, the dwc3 driver will reclaim
TRBs of started requests up to the request associated with the interrupt
event. Currently we don't check for interrupt due to missed isoc, and
the driver may attempt to reclaim TRBs beyond the associated event. This
causes invalid memory access when the hardware still owns the TRB. If
there's a missed isoc TRB with IMI (interrupt on missed isoc), make sure
to stop servicing further.
Note that only the last TRB of chained TRBs has its status updated with
missed isoc.
