The EDID of an HDR display defines EOTFs that are supported
by the display and can be set in the HDR metadata infoframe.
Userspace is expected to read the EDID and set an appropriate
HDR_OUTPUT_METADATA.
In drm_parse_hdr_metadata_block the kernel reads the supported
EOTFs from the EDID and stores them in the
drm_connector->hdr_sink_metadata. While doing so it also
filters the EOTFs to the EOTFs the kernel knows about.
When an HDR_OUTPUT_METADATA is set it then checks to
make sure the EOTF is a supported EOTF. In cases where
the kernel doesn't know about a new EOTF this check will
fail, even if the EDID advertises support.
Since it is expected that userspace reads the EDID to understand
what the display supports it doesn't make sense for DRM to block
an HDR_OUTPUT_METADATA if it contains an EOTF the kernel doesn't
understand.
This comes with the added benefit of future-proofing metadata
support. If the spec defines a new EOTF there is no need to
update DRM and an compositor can immediately make use of it.

The current interconnect provider interface is inherently racy as
providers are expected to be added before being fully initialised.
Specifically, nodes are currently not added and the provider data is not
initialised until after registering the provider which can cause racing
DT lookups to fail.
Add a new provider API which will be used to fix up the interconnect
drivers.
The old API is reimplemented using the new interface and will be removed
once all drivers have been fixed.

The interconnect framework currently expects that providers are only
removed when there are no users and after all nodes have been removed.
There is currently nothing that guarantees this to be the case and the
framework does not do any reference counting, but refusing to remove the
provider is never correct as that would leave a dangling pointer to a
resource that is about to be released in the global provider list (e.g.
accessible through debugfs).
Replace the current sanity checks with WARN_ON() so that the provider is
always removed.

Commit 596ff4a09b89 ("cpumask: re-introduce constant-sized cpumask
optimizations") changed cpumask_setall() to use "bitmap_set()" instead
of "bitmap_fill()", because bitmap_fill() would explicitly set all the
bits of a constant sized small bitmap, and that's exactly what we don't
want: we want to only set bits up to 'nr_cpu_ids', which is what
"bitmap_set()" does.
However, Yury correctly points out that while "bitmap_set()" does indeed
only set bits up to the required bitmap size, it doesn't _clear_ bits
above that size, so the upper bits would still not have well-defined
values.
Now, none of this should really matter, since any bits set past
'nr_cpu_ids' should always be ignored in the first place. Yes, the bit
scanning functions might return them as a result, but since users should
always consider the ">= nr_cpu_ids" condition to mean "no more bits",
that shouldn't have any actual effect (see previous commit 8ca09d5fa354
"cpumask: fix incorrect cpumask scanning result checks").
But let's just do it right, the way the code was _intended_ to work. We
have had enough lazy code that works but bites us in the *rse later
(again, see previous commit) that there's no reason to not just do this
properly.
It turns out that "bitmap_fill()" gets this all right for the complex
case, and really only fails for the inlined optimized case that just
fills the whole word. And while we could just fix bitmap_fill() to use
the proper last word mask, there's two issues with that:
- the cpumask case wants to do the _optimization_ based on "NR_CPUS is
a small constant", but then wants to do the actual bit _fill_ based
on "nr_cpu_ids" that isn't necessarily that same constant
- we have lots of non-cpumask users of bitmap_fill(), and while they
hopefully don't care, and probably would want the proper semantics
anyway ("only set bits up to the limit"), I do not want the cpumask
changes to impact other parts
So this ends up just doing the single-word optimization by hand in the
cpumask code. If our cpumask is fundamentally limited to a single word,
just do the proper "fill in that word" exactly. And if it's the more
complex multi-word case, then the generic bitmap_fill() will DTRT.
This is all an example of how our bitmap function optimizations really
are somewhat broken. They conflate the "this is size of the bitmap"
optimizations with the actual bit(s) we want to set.
In many cases we really want to have the two be separate things:
sometimes we base our optimizations on the size of the whole bitmap ("I
know this whole bitmap fits in a single word, so I'll just use
single-word accesses"), and sometimes we base them on the bit we are
looking at ("this is just acting on bits that are in the first word, so
I'll use single-word accesses").
Notice how the end result of the two optimizations are the same, but the
way we get to them are quite different.
And all our cpumask optimization games are really about that fundamental
distinction, and we'd often really want to pass in both the "this is the
bit I'm working on" (which _can_ be a small constant but might be
variable), and "I know it's in this range even if it's variable" (based
on CONFIG_NR_CPUS).
So this cpumask_setall() implementation just makes that explicit. It
checks the "I statically know the size is small" using the known static
size of the cpumask (which is what that 'small_cpumask_bits' is all
about), but then sets the actual bits using the exact number of cpus we
have (ie 'nr_cpumask_bits')
Of course, in a perfect world, the compiler would have done all the
range analysis (possibly with help from us just telling it that
"this value is always in this range"), and would do all of this for us.
But that is not the world we live in.
While we dream of that perfect world, this does that manual logic to
make it all work out. And this was a very long explanation for a small
code change that shouldn't even matter.

The LRU mechanism may look up a resource in the process of being removed
from an object. The locking rules here are a bit unclear but it looks
currently like res->bo assignment is protected by the LRU lock, whereas
bo->resource is protected by the object lock, while *clearing* of
bo->resource is also protected by the LRU lock. This means that if
we check that bo->resource points to the LRU resource under the LRU
lock we should be safe.
So perform that check before deciding to swap out a bo. That avoids
dereferencing a NULL bo->resource in ttm_bo_swapout().

definition, but unfortunately the ASoC topology framework only supports
up to 32 bit tokens.
This patch suggests breaking the 64 bit value in low and high parts, with
only the low-part extracted from topology and high-part only zeroes. Since
the curve duration is represented in hundred of nanoseconds, we can still
represent a 400s ramp, which is just fine. The defacto ABI change has no
effect on existing users since the IPC4 firmware has not been released just
yet.

When an IPC error happens while setting-up a widget during the FE
hw_params phase, the existing logic will unwind all previous
configurations but will overwrite the return status. The ALSA/ASoC
logic will then proceed with the prepare and trigger phases, even
though the firmware resources are not available.
Fix by returning the initial error code and ignoring the code returned
in the UNPREPARE phase.

It was a mistake to remove those delays, in light of comments in the

With the removal of widget setup during BE hw_params, the DAI config IPC
is never sent with the SOF_DAI_CONFIG_FLAGS_HW_PARAMS. This means that
the early bit clock feature required for certain codecs will be broken.
Fix this by saving the config flags sent during BE DAI hw_params and
reusing it when the DAI_CONFIG IPC is sent after the DAI widget is set
up. Also, free the DAI config before the widget is freed.
The DAI_CONFIG IPC sent during the sof_widget_free() does not have the
DAI index information. So, save the dai_index in the config during
hw_params and reuse it during hw_free.
For IPC4, do not clear the node ID during hw_free. It will be needed for
freeing the group_ida during unprepare.

The logic for the ioremap is to find the resource index 3 (IRAM) and
infer the BAR address by subtracting the IRAM offset. The BAR size
defined in hardware specifications is 2MB.
The commit 5947b2726beb6 ("ASoC: SOF: Intel: Check the bar size before
remapping") tried to find the BAR size by querying the resource length
instead of a pre-canned value, but by requesting the size for index 3
it only gets the size of the IRAM. That's obviously wrong and prevents
the probe from proceeding.
This commit attempted to fix an issue in a fuzzing/simulated
environment but created another on actual devices, so the best course
of action is to revert that change.

x86 ACPI boards which ship with only Android as their factory image usually
have pretty broken ACPI tables, relying on everything being hardcoded in
the factory kernel image and often disabling parts of the ACPI enumeration
kernel code to avoid the broken tables causing issues.
Part of this broken ACPI code is that sometimes these boards have _AEI
ACPI GPIO event handlers which are broken.
So far this has been dealt with in the platform/x86/x86-android-tablets.c
module, which contains various workarounds for these devices, by it calling
acpi_gpiochip_free_interrupts() on gpiochip-s with troublesome handlers to
disable the handlers.
But in some cases this is too late, if the handlers are of the edge type
then gpiolib-acpi.c's code will already have run them at boot.
This can cause issues such as GPIOs ending up as owned by "ACPI:OpRegion",
making them unavailable for drivers which actually need them.
Boards with these broken ACPI tables are already listed in
drivers/acpi/x86/utils.c for e.g. acpi_quirk_skip_i2c_client_enumeration().
Extend the quirks mechanism for a new acpi_quirk_skip_gpio_event_handlers()
helper, this re-uses the DMI-ids rather then having to duplicate the same
DMI table in gpiolib-acpi.c .
Also add the new ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS quirk to existing
boards with troublesome ACPI gpio event handlers, so that the current
acpi_gpiochip_free_interrupts() hack can be removed from
x86-android-tablets.c .

REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on REGMAP" to "select REGMAP".
