Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
The series adds support for echo reference functionality by allowing
the capturing of playback audio right before it leaves the DSP.
For this to work correctly we need a virtual DAI that is also connected
to the echo reference capture device and in absence of playback a
signal generator generates silence to allow the capture to run.
When the real playback starts, application will start to receive the
playback audio to be usable for echo reference.

ASoC: ti: davinci-mcasp: Add asynchronous mode support
McASP has dedicated clock & frame sync registers for both transmit

couples both TX & RX settings.
Add logic that enables asynchronous mode via ti,async-mode property. In
async mode, playback & record can be done simultaneously with different
audio configurations (tdm slots, tdm width, audio bit depth).
Note the ability to have different tx/rx DSP formats (i2s, dsp_a, etc.),
while possible in hardware, remains to be a gap as it require changes
to the corresponding machine driver interface.
Existing IIS (sync mode) and DIT mode logic remains mostly unchanged.
Exceptions are IIS mode logic that previously assumed sync mode, which has
now been made aware of the distinction. And shared logic across all modes
also now checks for McASP tx/rx-specific driver attributes. Those
attributes have been populated according to the original extent, ensuring
no divergence in functionality.
Constraints no longer applicable for async mode are skipped.
Clock selection options have also been added to include rx/tx-only clk_ids,
exposing independent configuration via the machine driver as well.
Note that asynchronous mode is not applicable for McASP in DIT mode,
which is a transmitter-only mode to interface w/ self-clocking formats.

If there's a mismatch between the DAI links in the machine driver and
the topology, it is possible that the playback/capture widget is not
set, especially in the case of loopback capture for echo reference
where we use the dummy DAI link. Return the error when the widget is not
set to avoid a null pointer dereference like below when the topology is
broken.
ASoC: SOF: sof-audio: Add support for loopback capture
An example of a DAI-less loopback pipeline would be the echo
reference capture in the speaker playback path. This pipeline
is set up as follows:
Host(Playback) -> mixin -> mixout -> gain -> module-copier -> DAI
|
V
Host(Capture) <- Process module <- virtual DAI
In the above example, the virtual DAI exploits the concept of an
aggregated DAI (one with a non-zero DAI ID) in topology to enable this
pipeline to work with DPCM. A virtual DAI is a DAI widget with a
non-zero DAI ID and hence is skipped when traversing the list of DAPM
widgets during widget prepare/set/up/free/unprepare. The process module
in the above pipeline generates 0's that are captured by the echo
reference PCM. When the playback path is active, the process module acts
as a passthrough module to allow the playback samples to be passthrough
to the capture host.
In order for these pipelines to work properly, the logic for
setting/preparing/freeing/unpreparing the widgets needs to be amended to
make sure that only the widgets that are in the pipeline in the same
direction as the PCM being started are set up. For example, when the
playback PCM is started, the capture pipeline widgets also show up in
the list of connected DAPM widgets but they shouldn't be set up yet
because the echo reference capture PCM hasn't been started yet.
Alternatively, when the echo reference capture PCM is started, the
playback pipeline widgets should not be setup.
Finally, the last step needed to put this all together is the set the
routes for widgets connecting the playback and the capture pipelines
when both are active.

For the record this solution has two issues not documented in any commit

a) this will not work in 'dspless' mode, where the link DMA is not
enabled. That's probably fine given that no one used that mode in
production, but that's a software restriction that you will not be able

b) this raise the question of how bandwidth will be managed. The premise
of BPT is that it uses all the bus bandwidth to guarantee predictable
firmware download times. If the available bandwidth is restricted by
other audio streams, then mechanically the startup latency will be
increased and vary - or you will have to run the bus at a higher
frequency to provision enough bandwidth for BPT but that means higher
power consumption. Or you will have to change the bus clock dynamically
which is possible at the hardware level for SDCA parts but not legacy

Add support for Anbernic's RG-DS audio amplifiers, powered by
Awinic AW87391 amplifier ICs. These chips typically require an
init sequence provided by firmware, but the manufacturer did not

the init sequence and use a device specific binding (rather than
a binding just for the aw87391).

iommu/tegra241-cmdqv: Reset VCMDQ in tegra241_vcmdq_hw_init_user()
The Enable bits in CMDQV/VINTF/VCMDQ_CONFIG registers do not actually reset
the HW registers. So, the driver explicitly clears all the registers when a
VINTF or VCMDQ is being initialized calling its hw_deinit() function.
However, a userspace VCMDQ is not properly reset, unlike an in-kernel VCMDQ
getting reset in tegra241_vcmdq_hw_init().
Meanwhile, tegra241_vintf_hw_init() calling tegra241_vintf_hw_deinit() will
not deinit any VCMDQ, since there is no userspace VCMDQ mapped to the VINTF
at that stage.
Then, this may result in dirty VCMDQ registers, which can fail the VM.
Like tegra241_vcmdq_hw_init(), reset a VCMDQ in tegra241_vcmdq_hw_init() to
fix this bug. This is required by a host kernel.

perf: sched: Fix perf crash with new is_user_task() helper
In order to do a user space stacktrace the current task needs to be a user
task that has executed in user space. It use to be possible to test if a
task is a user task or not by simply checking the task_struct mm field. If
it was non NULL, it was a user task and if not it was a kernel task.
But things have changed over time, and some kernel tasks now have their
own mm field.
An idea was made to instead test PF_KTHREAD and two functions were used to
wrap this check in case it became more complex to test if a task was a
user task or not[1]. But this was rejected and the C code simply checked
the PF_KTHREAD directly.
It was later found that not all kernel threads set PF_KTHREAD. The io-uring
helpers instead set PF_USER_WORKER and this needed to be added as well.
But checking the flags is still not enough. There's a very small window
when a task exits that it frees its mm field and it is set back to NULL.
If perf were to trigger at this moment, the flags test would say its a
user space task but when perf would read the mm field it would crash with
at NULL pointer dereference.
Now there are flags that can be used to test if a task is exiting, but
they are set in areas that perf may still want to profile the user space
task (to see where it exited). The only real test is to check both the
flags and the mm field.
Instead of making this modification in every location, create a new
is_user_task() helper function that does all the tests needed to know if
it is safe to read the user space memory or not.

net: fix segmentation of forwarding fraglist GRO
This patch enhances GSO segment handling by properly checking
the SKB_GSO_DODGY flag for frag_list GSO packets, addressing
low throughput issues observed when a station accesses IPv4
servers via hotspots with an IPv6-only upstream interface.
Specifically, it fixes a bug in GSO segmentation when forwarding
GRO packets containing a frag_list. The function skb_segment_list
cannot correctly process GRO skbs that have been converted by XLAT,
since XLAT only translates the header of the head skb. Consequently,
skbs in the frag_list may remain untranslated, resulting in protocol
inconsistencies and reduced throughput.
To address this, the patch explicitly sets the SKB_GSO_DODGY flag
for GSO packets in XLAT's IPv4/IPv6 protocol translation helpers
(bpf_skb_proto_4_to_6 and bpf_skb_proto_6_to_4). This marks GSO
packets as potentially modified after protocol translation. As a
result, GSO segmentation will avoid using skb_segment_list and
instead falls back to skb_segment for packets with the SKB_GSO_DODGY
flag. This ensures that only safe and fully translated frag_list
packets are processed by skb_segment_list, resolving protocol
inconsistencies and improving throughput when forwarding GRO packets
converted by XLAT.

wifi: mac80211: correctly decode TTLM with default link map
TID-To-Link Mapping (TTLM) elements do not contain any link mapping
presence indicator if a default mapping is used and parsing needs to be
skipped.
Note that access points should not explicitly report an advertised TTLM
with a default mapping as that is the implied mapping if the element is
not included, this is even the case when switching back to the default
mapping. However, mac80211 would incorrectly parse the frame and would
also read one byte beyond the end of the element.
