4a0dcc6a15 KVM: selftests: access_tracking_perf_test: bump number of NUMA nodes to 32
It's rare to find a system that has more than 4 sockets,
but a system can have more than 4 NUMA nodes if each socket
exposes its chiplets as separate NUMA nodes.

In particular, our CI caught a failure in this test on a system with
two sockets, each containing an 'AMD EPYC 7601 32-Core Processor'.

Bump the limit to 32, just in case.

ASoC: don't use array if single pattern
Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> says:

Current ASoC supports snd_soc_daifmt_parse_format() which can specify DAI
format by "dai-format" property from DT.
But strictly speaking, it is SW settings, so doesn't match to DT's policy.

Current ASoC is supporting auto format select via
snd_soc_dai_ops :: .auto_selectable_formats.
But the user is very few today.

DT doesn't need to specify the DAI format via "dai-format", if both CPU
and Codec drivers were supporting .auto_selectable_formats. It will be
automatically selected from .auto_selectable_formats.

But, I noticed that current auto format select method can't handle all cases.
For example, current .auto_selectable_formats is like below

	static u64 xxx_auto_formats[] = {
(A)		/* First Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J	|
		SND_SOC_POSSIBLE_DAIFMT_NB_NF	|
		SND_SOC_POSSIBLE_DAIFMT_NB_IF	|	(x)
		SND_SOC_POSSIBLE_DAIFMT_IB_NF	|
		SND_SOC_POSSIBLE_DAIFMT_IB_IF,		(x)

		/* Second Priority */
(B)		SND_SOC_POSSIBLE_DAIFMT_DSP_A	|	(y)
		SND_SOC_POSSIBLE_DAIFMT_DSP_B,		(y)
	};

It try to find DAI format from (A) first, and next it will use (A | B).
But it can't handle the format if some format were independent.
For example, DSP_x (y) can't use with xB_IF (x), etc.

So, I would like to update the method. New method doesn't use OR.
It try to find DAI format from (a), next it will use (b).

	static u64 xxx_auto_formats[] = {
(a)		/* First Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J	|
		SND_SOC_POSSIBLE_DAIFMT_NB_NF	|
		SND_SOC_POSSIBLE_DAIFMT_NB_IF	|
		SND_SOC_POSSIBLE_DAIFMT_IB_NF	|
		SND_SOC_POSSIBLE_DAIFMT_IB_IF,

		/* Second Priority */
(b)		SND_SOC_POSSIBLE_DAIFMT_DSP_A	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_B	|
		SND_SOC_POSSIBLE_DAIFMT_NB_NF	|
		SND_SOC_POSSIBLE_DAIFMT_IB_NF,
	};

Switch old method to new method, Current auto select user need to update
.auto_selectable_formats. Fortunately, current few users doesn't have
above limitation. update (A)(B) to (a)(b) style is possible.

	a = A
	b = A | B

I would like to update method, and add .auto_selectable_formats
support on all drivers.

One note is that auto select might not find best format on some CPU/Codec
combination. So "dai-format" is necessary anyway.

And, there haven't been any big problems on .auto_selectable_formats,
because there were few users.
But if all drivers try to use this, it cannot be denied that they may
encounter unknown problems... In such case, "dai-format" can help, though.

ASoC: audio-graph-card2: recommend to use auto select DAI format
"Simple Audio Card", "Audio Graph Card", "Audio Graph Card2" are
possible to set DAI format via DT.

OTOH, ASoC is supporting .auto_selectable_formats to select DAI
format automatically. Let's recommend to use it on "Audio Graph Card2".
One note is that it keeps supporting DAI format setting via DT.

ASoC: update auto format selection method
Current DAI supports auto format selection. It allow to have array like
below.

(X)	static u64 xxx_auto_formats[] = {
(A)		/* First Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J,

		/* Second Priority */
(B)		SND_SOC_POSSIBLE_DAIFMT_DSP_A	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_B,
	};

It try to find available format from I2S/LEFT_J first (A).
Then, try to find from I2S/LEFT_J/DSP_A/DSP_B if couldn't find (A)+(B).
(OR:ed)

In this method, it can't handle if there is format combination.
For example, some driver has pattern.

Pattern1
	I2S/RIFHT_J/LEFT_J (FORMAT) and NB_NF/IB_IF/IB_NF/NB_IF (INV)_
Pattern2
	DSP_A/DSP_B        (FORMAT) and NB_NF/      IB_NF

Because it will try to OR Pattern1 and Pattern2, un-supported
pattern might be selected.

This patch update method not to use OR, and assumes full format array.
Above sample (X) need to be

	static u64 xxx_auto_formats[] = {
		/* First Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J,

		/* Second Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_A	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_B,
	};

Note: It doesn't support Multi CPU/Codec for now

ASoC: adau1372: Clear PLL_EN on failed PLL lock without reset GPIO
The PLL lock failure path in adau1372_set_power() unwinds by putting
the regmap back in cache-only mode, asserting the optional power-down
GPIO and disabling mclk.

adau1372_enable_pll() enables CLK_CTRL.PLL_EN before polling the PLL
lock bit. If the lock fails on a board without a power-down GPIO, the
error path disables mclk and returns an error, but leaves PLL_EN set in
the hardware register. The normal power-off path already handles the
no-GPIO case by explicitly clearing PLL_EN.

Mirror that cleanup in the PLL lock failure path and clear PLL_EN while
the regmap is still live, before switching it back to cache-only mode.

 "Here are two small bugfixes for a staging driver to fix a
  much-reported issue.

  The fixes are for the rtl8723bs driver and it's something that many
  scanning tools keep tripping over in convoluted ways (and seems to be
  able to be triggered by network traffic)

  These fixes have been in linux-next for many weeks with no reported

785562e31d vfio: selftests: Ensure libvfio output dirs are always created
Add an explicit dependency between the output object files and the
output directories that need to be created to hold those files. This
ensures that the output directories are always created.

Creating the output directories at parse time (current behavior) doesn't
support the scenario where someone does "make clean all". The
directories will be created during parsing, deleted during "clean" and
then not available for the "all" target.

Use an order-only prerequisite for the output directories, rather than a
normal prerequisite, to avoid unnecessary recompilations.

aa8a76711c cxl/region: Fill first free targets[] slot during auto-discovery
Any invalid endpoint decoder pointer in the target array of an active
region is not allowed by cxl driver. This means cxl driver always
assumes the first p->nr_targets entries of the target array in an
auto-assembly region are valid. However, there are scenarios that could
leave NULL endpoint decoder pointer holes in the target array.

1. When cxl_cancel_auto_attach() removes an endpoint decoder from a
   target array, the target slot is set to NULL. If the removed endpoint
   decoder is not the last element in the target array, the target array
   will contain a NULL hole.

2. When a auto-assembly region removes an assigned endpoint decoder, if
   the removed endpoint decoder is not the last element in the target
   array, always remains a NULL hole in the target array.

When a NULL pointer hole exists in a region's target array, it
introduces two potential problems:
1. Access an endpoint decoder via a NULL pointer. it always trigger
   calltrace like that.
    Oops: general protection fault, probably for non-canonical address 0xdffffc0000000008: 0000 [#1] SMP KASAN PTI

2. Not having enough valid endpoint decoders attached to an
   auto-assembly region. if an auto-assembly region is created with lock
   flag or assigned endpoint decoder with lock flag, which means
   assigned endpoint decoder will not be reset during detaching, they
   could re-attach to the auto-assembly region again. But cxl region
   driver relies on p->nr_targets to verify whether the required number
   of endpoint decoders has been attached, and NULL endpoint decoder
   pointers are still counted in that case.

To fix above issues, adjust cxl_region_attach_auto() logic to find the
first free target slot for endpoint decoder attachment, this ensures
NULL holes in the target array are filled, rather than adding new
endpoint decoders at the tail of the target array.

cbda6a2c2b cxl/region: Fix out-of-bounds access in cxl_cancel_auto_attach()
In cxl_cancel_auto_attach(), it assumes cxled->pos is a valid index for
accessing p->targets[]. However, cxled->pos can be set to negative errno
in cxl_region_sort_targets() if cxl_calc_interleave_pos() fails. This
causes the driver to use a negative index to access p->targets[],
resulting in out-of-bounds access.

Fix it by walking p->targets[] instead of using cxled->pos directly.

ccb2fd725d of: Respect #{iommu,msi}-cells in maps
So far our parsing of {iommu,msi}-map properties has always blindly
assumed that the output specifiers will always have exactly 1 cell.
This typically does happen to be the case, but is not actually enforced
(and the PCI msi-map binding even explicitly states support for 0 or 1
cells) - as a result we've now ended up with dodgy DTs out in the field
which depend on this behaviour to map a 1-cell specifier for a 2-cell
provider, despite that being bogus per the bindings themselves.

Since there is some potential use in being able to map at least single
input IDs to multi-cell output specifiers (and properly support 0-cell
outputs as well), add support for properly parsing and using the target
nodes' #cells values, albeit with the unfortunate complication of still
having to work around expectations of the old behaviour too.

Since there are multi-cell output specifiers, the callers of of_map_id()
may need to get the exact cell output value for further processing.
Update of_map_id() to set args_count in the output to reflect the actual
number of output specifier cells.

Change of_map_id() to take a pointer to struct of_phandle_args
instead of passing target device node and translated IDs separately.
Update all callers accordingly.

Add an explicit filter_np parameter to of_map_id() and of_map_msi_id()
to separate the filter input from the output. Previously, the target
parameter served dual purpose: as an input filter (if non-NULL, only
match entries targeting that node) and as an output (receiving the
matched node with a reference held). Now filter_np is the explicit
input filter and arg->np is the pure output.

Previously, of_map_id() would call of_node_put() on the matched node
when a filter was provided, making reference ownership inconsistent.
Remove this internal of_node_put() call so that of_map_id() now always
transfers ownership of the matched node reference to the caller via
arg->np. Callers are now consistently responsible for releasing this
reference with of_node_put(arg->np) when done.

d4b52f83f1 of: Add convenience wrappers for of_map_id()
Since we now have quite a few users parsing "iommu-map" and "msi-map"
properties, give them some wrappers to conveniently encapsulate the
appropriate sets of property names. This will also make it easier to
then change of_map_id() to correctly account for specifier cells.

769f0b350c tools/testing/cxl: Resolve auto-region decoder targets like real HW
The mock auto-region created at module load wrote switch and host-bridge
decoder target[] directly, in addition to target_map[]. Real HW programs
only target_map[] and resolves target[] as dports enumerate, via
update_decoder_targets(). Region replay already follows that ordering,
the initial auto-region did not.

Drop the direct target[] writes and call
cxl_port_update_decoder_targets() so target[] is resolved the same way
as real HW and region replay, exercising more of the auto-region driver
path.

This is inspired by the discussion [1] below:

ASoC: use scoped OF node handling in manual cleanup paths
Cássio Gabriel <cassiogabrielcontato@gmail.com> says:

Some ASoC drivers still manually release child OF nodes
when leaving child-node iteration loops early.

Convert these focused cases to scoped OF node cleanup
so early returns and normal loop exits keep the same node
lifetime handling without explicit of_node_put() calls.

- Patch 1 updates qcom_snd_parse_of() to use
  for_each_available_child_of_node_scoped() for link nodes and
  __free(device_node) for temporary cpu/platform/codec child nodes.
- Patch 2 updates fsl_qmc_audio to use
  for_each_available_child_of_node_scoped() for DAI child-node parsing.
- Patch 3 updates cygnus-ssp to use
  for_each_available_child_of_node_scoped() for SSP child-node parsing.

qcom_snd_parse_of() manually drops the link child node and the

Use for_each_available_child_of_node_scoped() for the link node and
__free(device_node) for the named child nodes. This keeps the existing
ownership rules for DAI component phandle references, while removing the
manual cleanup labels from a path that has previously needed OF refcount
fixes.

ASoC: sdw_utils: fix missing component_name for cs42l43 part_id 0x2A3B
commit 87a3f5c8ac ("ASoC: sdw_utils: cs42l43: allow spk component names
to be combined") moved spk:cs42l43-spk generation from rtd_init() into
the asoc_sdw_rtd_init() generic path by adding component_name to
codec_info_list entries. However, only the 0x4243 cs42l43 entry was
updated; the 0x2A3B entry (vendor_id 0x01fa, Cirrus Logic cs42l43 with
sidecar bridge) was missed.

Without component_name on the 0x2A3B dp6 DAI, asoc_sdw_rtd_init() never
accumulates spk_components and never appends 'spk:cs42l43-spk' (or its
sidecar alias 'spk:cs35l56-bridge') to card->components. The sof-soundwire
UCM regex ' spk:([a-z0-9]+...)' then fails to match, causing WirePlumber
to mark all HiFi profiles as unavailable=no and fall back to the Off
profile — resulting in Dummy Output in GNOME.

The existing sidecar redirect in asoc_sdw_rtd_init() already handles the
SOC_SDW_SIDECAR_AMPS case: when component_name is 'cs42l43-spk' and
sidecar amps are active, it substitutes 'cs35l56-bridge' into
card->components, which matches the existing cs35l56-bridge.conf UCM file.

661c092f98 cxl: Align interleave decode/encode helpers with their callers
The interleave conversion helpers translate between encoded HDM
interleave values and the granularity and way values used by the
driver.

These helpers have been a recurring source of static analysis
complaints that expose type mismatches and potentially uninitialized
outputs. Fix those issues in the helpers so callers inherit the
consistent behavior automatically.

The decode and encode helpers have different interface issues.

The decode helpers return values through unsigned int pointers, but
the decoded values are ultimately represented as int throughout the
driver. Align the helper interfaces with their callers by changing
the out-parameters to int * and updating the handful of affected
locals to match.

The encode helpers leave their out-parameters unchanged on error. That
means callers that ignore the return value may observe uninitialized
encoded values. Initialize the outputs so failed conversions leave
defined values. This issue was originally reported by Purva and the
helper-side fix was suggested by Dan [1].

Tidy up a related, pre-existing, printk format specifier mismatch in
cxl_validate_translation_params().

No functional change for valid interleave parameters.
