Srinivas Kandagatla <srinivas.kandagatla@oss.qualcomm.com> says:
This patchset contains few fixes for the bugs hit during testing with
Monza EVK platform
- around array out of bounds access on dai ids which keep extending but
the drivers seems to have hardcoded some numbers, fix this and clean
the mess up
- fix few issues discovered while trying to shut down dsp.
- flooding rpmsg with write requests due to not resetting queue pointer,
fix this resetting the pointer in trigger stop.
- possible multiple graph opens which can result in open failures.
Apart from this few new enhancements to the dsp side
- add new LPI MI2S and senary dai entries
- handle pipewire and Displayport issues by moving graph start to
trigger level, which should fix outstanding pipewire and DP issues on
Qualcomm SoCs.
- remove some unnessary loops in hot path
- support early memory map on DSP.
Tested this on top of linux-next on VENTUNO-Q platform.
Add new dai ids entries for LPASS LPI MI2S and SENARY MI2S audio lines.

Pull overlayfs fixes from Amir Goldstein:
- Fix regression in 'xino' feature detection
I clumsily introduced this regression myself when working on another
subsystem (fsnotify). Both the regression and the fix have almost no
visible impact on users except for some kmsg prints.
- Fix to performance regression in v6.12.
This regression was reported by Google COS developers.
It is not uncommon these days for the year-old mature LTS to get
adopted by distros and get exposed to many new workloads. We made a
sub-smart move of making a behavior change in v6.12 which could
impact performance, without making it opt-in. Fixing this mistake
retroactively, to be picked by LTS.

Commit 7d6899fb69 ("ovl: fsync after metadata copy-up") was done to
fix durability of overlayfs copy up on an upper filesystem which does
not enforce ordering on storing of metadata changes (e.g. ubifs).
In an earlier revision of the regressing commit by Lei Lv, the metadata
fsync behavior was opt-in via a new "fsync=strict" mount option.
We were hoping that the opt-in mount option could be avoided, so the
change was only made to depend on metacopy=off, in the hope of not
hurting performance of metadata heavy workloads, which are more likely
to be using metacopy=on.
This hope was proven wrong by a performance regression report from Google
COS workload after upgrade to kernel 6.12.
This is an adaptation of Lei's original "fsync=strict" mount option
to the existing upstream code.
The new mount option is mutually exclusive with the "volatile" mount
option, so the latter is now an alias to the "fsync=volatile" mount
option.

adau1372_set_power() had two related error handling issues in its enable
path: clk_prepare_enable() was called but its return value discarded, and
adau1372_enable_pll() was a void function that silently swallowed lock
failures, leaving mclk enabled and adau1372->enabled set to true despite
the device being in a broken state.
Patch 1 fixes the unchecked clk_prepare_enable() by making
adau1372_set_power() return int and propagating the error.
Patch 2 converts adau1372_enable_pll() to return int and adds a full
unwind in adau1372_set_power() if PLL lock fails, reversing the regcache,
GPIO power-down, and clock state.

The adm1177 driver exposes the current alert threshold through
hwmon_curr_max_alarm. This violates the hwmon sysfs ABI, where
*_alarm attributes are read-only status flags and writable thresholds
must use currN_max.
The driver also stores the threshold internally in microamps, while
currN_max is defined in milliamps. Convert the threshold accordingly
on both the read and write paths.
Widen the cached threshold and related calculations to 64 bits so
that small shunt resistor values do not cause truncation or overflow.
Also use 64-bit arithmetic for the mA/uA conversions, clamp writes
to the range the hardware can represent, and propagate failures from
adm1177_write_alert_thr() instead of silently ignoring them.
Update the hwmon documentation to reflect the attribute rename and
the correct units returned by the driver.

Capability and emitted to the kernel log in raw hex format. Document the
existence and usage of tlp-tool, which decodes the TLP Header into
human-readable form.
The TLP Header hints at the root cause of an error, yet is often ignored
because of its seeming opaqueness. Instead, PCIe errors are frequently
worked around by a change in the kernel without fully understanding the
actual source of the problem. With more documentation on available tools
we'll hopefully come up with better solutions.
There are also wireshark dissectors for TLPs, but it seems they expect a
complete TLP, not just the header, and they cannot grok the hex format
emitted by the kernel directly. tlp-tool appears to be the most cut and
dried solution out there.

We look up a netdev during prep of Netlink ops (pre- callbacks)
and take a ref to it. Then later in the body of the callback
we take its lock or RCU which are the actual protections.
The netdev may get unregistered in between the time we take
the ref and the time we lock it. We may allocate the hierarchy
after flush has already run, which would lead to a leak.
Take the instance lock in pre- already, this saves us from the race
and removes the need for dedicated lock/unlock callbacks completely.
After all, if there's any chance of write happening concurrently
with the flush - we're back to leaking the hierarchy.
We may take the lock for devices which don't support shapers but
we're only dealing with SET operations here, not taking the lock
would be optimizing for an error case.

James Calligeros <jcalligeros99@gmail.com> says:
This series introduces some infrastructure to allow platform drivers
to specify what a DAI should be doing when it is not active on the
bus. The primary use case for this is configuring bus keepers which
may be integrated into various codecs. The instigating use case for
this functionality is an interesting bus topology on Apple Silicon
laptops with multiple codecs.
Most Apple Silicon laptops have six codecs split into groups of
three, driving a pair of dual opposed woofers and a tweeter for
L/R stereo sound. These codecs report the voltage and current across
their connected voice coils back to the SoC via the SDOUT pin,
represented as PCM data sent via configurable TDM slots. This data is
used in conjunction with the connected speaker's Thiele/Small Parameters
to ensure that the speaker is not being driven to levels that would
permanently damage them. This is integrated into CoreAudio on macOS.
speakersafetyd[1] handles this for Linux.
All of the codec SDOUT pins are attached to a single receiver port
on the SoC's I2S peripheral, however are split across two physical
data lines (one each for the left and right codec groups). The receiver
has an OR gate in front of it, which is used to sum the two lines.
If at any point a codec is trying to transmit data, and the "opposite"
line ends up floating high, the transmitting codec's data will be
corrupted. We need to guarantee that the idle line stays idle.
In the downstream Asahi Linux kernel[2], we set up one codec in each
group to zero-fill or pull down its line while a codec on the opposite
line is actively transmitting. This is done entirely in the codec
driver, however this approach is over-fit for this one use case. This
sort of functionality may also be of use for other hardware, so following
previous mailing list discussions[3], I have tried to expose the
functionality in a more configurable and generic way.
I have integrated this approach into our downstream platform driver
and select Devicetrees as an example of how this mechanism is intended
to be used[4].

Add properties to describe TDM slot idle behaviour. These properties can
be used to describe how a DAI is supposed to behave when not active.
For example, Apple Silicon laptops split a single I2S bus between two
physical lines which are combined at an OR gate in front of the
receiving port. One codec on each line is expected to transmit zeroes
during the active TDM slots of the opposite line, or we will have corrupted
data at the receiver.

Here is a large chunk of USB driver fixes for 7.0-rc4. Included in here
are:
- usb gadget reverts due to reported issues, and then a follow-on fix
to hopefully resolve the reported overall problem
- xhci driver fixes
- dwc3 driver fixes
- usb core "killable" bulk message api addition to fix a usbtmc driver
bug where userspace could hang the driver for forever
- small USB driver fixes for reported issues
- new usb device quirks
All except the last USB device quirk change have been in linux-next with
no reported issues. That one came in too late, and is "obviously
correct" :)

GPIOs with "gpio" suffix were long time ago deprecated, thus
"reset-gpios" should be used. Linux kernel supports both, thus this
only documents desired choice of ABI.

A recently added quirk does not fit in the left column of the table,
so it all has to be reformatted and realigned.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Add KVM_X86_QUIRK_VMCS12_ALLOW_FREEZE_IN_SMM to allow L1 to set
FREEZE_IN_SMM in vmcs12's GUEST_IA32_DEBUGCTL field, as permitted
prior to commit 6b1dd26544 ("KVM: VMX: Preserve host's
DEBUGCTLMSR_FREEZE_IN_SMM while running the guest"). Enable the quirk
by default for backwards compatibility (like all quirks); userspace
can disable it via KVM_CAP_DISABLE_QUIRKS2 for consistency with the
constraints on WRMSR(IA32_DEBUGCTL).
Note that the quirk only bypasses the consistency check. The vmcs02 bit is
still owned by the host, and PMCs are not frozen during virtualized SMM.
In particular, if a host administrator decides that PMCs should not be
frozen during physical SMM, then L1 has no say in the matter.

- Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from being

- Document that vcpu->mutex is take outside of kvm->slots_lock and
