Currently, CONFIG_SND_SOC_SDCA is a hidden Kconfig symbol, so it must be
selected by a user selectable symbol to be enabled. However, it may not
be possible for configurations to select this symbol without running
into a recursive dependency issue:
error: recursive dependency detected!
symbol SOUNDWIRE depends on SND_SOC_SDCA_OPTIONAL
symbol SND_SOC_SDCA_OPTIONAL default value contains SND_SOC_SDCA
symbol SND_SOC_SDCA is selected by SND_SOC_ES9356
symbol SND_SOC_ES9356 depends on SOUNDWIRE
Turn CONFIG_SND_SOC_SDCA into a user selectable symbol so that drivers
can depend on it and allow the user to enable it explicitly.

SRC can only change the rate, we can still allow different bit depth and
channels to be handled, the only restriction is that the input and output
must have matching bit depth and channel format.
In a separate patch do a sanity check for the number of formats on the
input and output side as SRC/ASRC must have at least one of them.
Link: https://patch.msgid.link/20260526105748.26149-1-peter.ujfalusi@linux.intel.com
The SRC module can only change the rate, it keeps the format and channels
intact, but this does not mean the num_output_formats must be 0:
The SRC module can support different formats/channels, we just need to
check if the output format lists the correct combination of out rate and
the input format/channels.
Change the logic to prioritize the sink_rate of the module as target rate,
then the rate of the FE in case of capture or in case of playback check the
single rate specified in the output formats.

The MAX98090 codec driver currently exposes a custom
max98090_mic_detect() helper for machine drivers to register a headset
jack.
This series converts the driver to use the standard component
.set_jack callback and updates the mt8173-max98090 machine driver to use
snd_soc_component_set_jack() instead of the codec-specific helper.
Using the standard callback removes the need for a custom exported
symbol and allows machine drivers to use the common ASoC jack
registration interface. This also improves compatibility with machine
drivers, such as Qualcomm platforms, that already rely on
snd_soc_component_set_jack().

Currently dapm_find_widget() manually constructs a prefixed widget name
based on the provided DAPM context and compares it using strcmp(). This
happens to work in most cases because callers usually know which DAPM
context the target widget belongs to and pass in the matching DAPM
context.
However, this assumption breaks when search_other_contexts is enabled.
In such cases, callers may intentionally pass a different DAPM context,
while searching for a widget that actually belongs to another DAPM
context.
For example, when searching for a "DAC" widget, the widget belongs to
the codec DAPM and be registered with a codec prefix, while the caller
passes card->dapm and intends to search across all DAPM contexts. The
current implementation incorrectly applies the caller card DAPM causing
the lookup to fail even though the widget exists on the card.
Improve the matching strategy to support both use cases:
1. When the caller provides a fully qualified name with prefix, perform
exact string matching. This preserves the ability to use prefixes for
disambiguation.
2. When the caller provides a bare widget name without prefix, try exact
matching first, then fall back to prefix-stripped comparison using
snd_soc_dapm_widget_name_cmp().
To determine whether the pin name includes a prefix, a new helper
function snd_soc_dapm_pin_has_prefix() is introduced. It checks if the
pin name starts with any known component prefix on the card.
This fixes widget lookup failures when searching across different DAPM
contexts while maintaining backward compatibility for explicitly
prefixed lookups.

Troy Mitchell <troy.mitchell@linux.spacemit.com> says:
On some SoCs (e.g. SpacemiT K3), multiple I2S controllers share the
same physical BCLK. When one controller is already streaming, the
others must use hw_params that result in the same BCLK rate, otherwise
the shared clock would be reconfigured and corrupt the active stream.
This series adds framework-level support for this constraint:
Patch 1 adds the dt-bindings for the spacemit,k3-i2s compatible.
The K3 SoC uses the same I2S IP as K1 but requires additional clocks:
a dedicated sysclk_div, along with c_sysclk and c_bclk which are
shared across multiple I2S controllers.
Patch 2 adds a DEFINE_GUARD wrapping snd_soc_card_mutex_lock() and
snd_soc_card_mutex_unlock() so that scope-based locking picks up the
SND_SOC_CARD_CLASS_RUNTIME lockdep subclass.
Patch 3 adds the constraint logic in soc-pcm.c. During PCM open,
every DAI that has a bclk clock pointer gets a hw_rule registered
unconditionally. The rule callback runs at hw_refine time: it scans
the card for an active peer sharing the same physical BCLK (via
clk_is_match()) that has already completed hw_params, then constrains
the current stream's rate to match the established BCLK rate. The
first DAI to complete hw_params is unconstrained; subsequent DAIs
must match. Two modes are supported:
- Default (I2S): BCLK = rate * channels * sample_bits. The rule
derives the valid rate range from the current channel and
sample_bits intervals.
- Explicit ratio (TDM): if the driver sets dai->bclk_ratio
(e.g. slots * slot_width), the rule computes the single valid
rate as active_bclk_rate / bclk_ratio.
This series was prompted by review feedback on the SpacemiT K3 I2S
series, where a vendor-specific fixed-sample-rate property was rejected
in favor of a generic framework solution:
https://lore.kernel.org/all/afFqgF6ZRwYdfUmL@sirena.co.uk/
Link: https://patch.msgid.link/20260522-i2s-same-blk-v4-0-a71a86faaa20@linux.spacemit.com
When multiple CPU DAIs on the same sound card share the same physical
BCLK, add a hw_rule during PCM open that constrains the sample rate so
the resulting BCLK rate stays consistent across all sharing DAIs.
The rule callback scans all DAIs on the card at hw_refine time, looking
for an active peer that shares the same physical BCLK (via
clk_is_match()) and has already completed hw_params (checked via
dai->symmetric_rate != 0). This ensures the constraint uses the real
BCLK rate established by the peer's clk_set_rate() in hw_params, not a
stale boot-time default.
The first DAI to complete hw_params is unconstrained (no active peer
yet); subsequent DAIs are constrained to match.
The rule supports two modes:
- If the DAI has an explicit bclk_ratio set (e.g. for TDM where
BCLK = rate * slots * slot_width), the rate is constrained to
active_bclk_rate / bclk_ratio.
- Otherwise, the default formula BCLK = rate * channels * sample_bits
is used to derive the valid rate range.
The constraint is purely additive: DAIs that do not set a bclk clock
pointer are completely unaffected.

Add a bclk field to struct snd_soc_dai and a helper function
snd_soc_dai_set_bclk_clk() that platform drivers can use to declare
which clock is their BCLK.
Also cache the bclk_ratio in snd_soc_dai_set_bclk_ratio() so that
the framework can use it later in hw_rule evaluation for TDM
configurations where BCLK = rate * slots * slot_width.
When multiple DAIs on the same card share the same physical BCLK
(detected via clk_is_match()), the ASoC core can automatically
constrain their hw_params so that the resulting BCLK rates are
compatible. This commit adds the data structure support; the actual
constraint logic follows in the next patch.

Hygon Family 18h CPUs are derived from AMD Family 17h (Zen1) silicon and
share the same erratum #1235: hardware may read a stale IsRunning=1 bit
during ICR write emulation and silently fail to generate an
AVIC_IPI_FAILURE_TARGET_NOT_RUNNING VM-Exit on the sending vCPU.
The absence of the VM-Exit causes KVM to miss the required wakeup of
blocking target vCPUs, leading to hung vCPUs and unbounded delays in
guest execution.
Extend the existing AMD Family 17h erratum #1235 workaround to also cover
Hygon Family 18h. With IPI virtualization disabled, KVM never sets
IsRunning=1 in the Physical ID table, so every non-self IPI generates a
VM-Exit and is correctly emulated.

Add checks in the APIC bus clock test to verify that querying
KVM_CAP_X86_APIC_BUS_CYCLES_NS on the VM after changing the frequency
returns the VM's actual APIC cycle length, not KVM's default. For
giggles, verify that KVM still returns its default frequency for the
system-scoped check.

When KVM_CAP_X86_APIC_BUS_CYCLES_NS is queried on a specific VM, return the
VM's configured APIC bus frequency, not KVM's default. Aside from the fact
that returning the default frequency is blatantly wrong if userspace has
changed the frequency, returning the configured frequency means userspace
can blindly trust the result, e.g. when filling PV CPUID information that
communicates the APIC bus frequency to the guest.

<bits/endian.h> is a glibc-internal header that explicitly states it
should never be included directly:
#error "Never use <bits/endian.h> directly; include <endian.h> instead."
Replace it with the correct public header <endian.h> which works on
all C libraries including musl. Building KVM selftests with musl-gcc
fails with:
