Commit 719e1f561a ("ACPI: Execute platform _OSC also with query bit
clear") makes acpi_bus_osc_negotiate_platform_control() not only query
the platforms capabilities but it also commits the result back to the
firmware to report which capabilities are supported by the OS back to
the firmware
On certain systems the BIOS loads SSDT tables dynamically based on the
capabilities the OS claims to support. However, on these systems the
_OSC actually clears some of the bits (under certain conditions) so what
happens is that now when we call the _OSC twice the second time we pass
the cleared values and that results errors like below to appear on the
system log:
ACPI BIOS Error (bug): Could not resolve symbol [\_PR.PR00._CPC], AE_NOT_FOUND (20210105/psargs-330)
ACPI Error: Aborting method \_PR.PR01._CPC due to previous error (AE_NOT_FOUND) (20210105/psparse-529)
In addition the ACPI 6.4 spec says following [1]:
If the OS declares support of a feature in the Support Field in one
call to _OSC, then it must preserve the set state of that bit
(declaring support for that feature) in all subsequent calls.
Based on the above we can fix the issue by passing the same set of
capabilities to the platform wide _OSC in both calls regardless of the
query flag.
While there drop the context.ret.length checks which were wrong to begin
with (as the length is number of bytes not elements). This is already
checked in acpi_run_osc() that also returns an error in that case.

Currently, a device description can be obtained using ACPI, if the _STR
method exists for a particular device, and then exposed to the userspace
via a sysfs object as a string value.
If the _STR method is available for a given device then the data
(usually a Unicode string) is read and stored in a buffer (of the
ACPI_TYPE_BUFFER type) with a pointer to said buffer cached in the
struct acpi_device_pnp for later access.
The description_show() function is responsible for exposing the device
description to the userspace via a corresponding sysfs object and
internally calls the utf16s_to_utf8s() function with a pointer to the
buffer that contains the Unicode string so that it can be converted from
UTF16 encoding to UTF8 and thus allowing for the value to be safely
stored and later displayed.
When invoking the utf16s_to_utf8s() function, the description_show()
function also sets a limit of the data that can be saved into a provided
buffer as a result of the character conversion to be a total of
PAGE_SIZE, and upon completion, the utf16s_to_utf8s() function returns
an integer value denoting the number of bytes that have been written
into the provided buffer.
Following the execution of the utf16s_to_utf8s() a newline character
will be added at the end of the resulting buffer so that when the value
is read in the userspace through the sysfs object then it would include
newline making it more accessible when working with the sysfs file
system in the shell, etc. Normally, this wouldn't be a problem, but if
the function utf16s_to_utf8s() happens to return the number of bytes
written to be precisely PAGE_SIZE, then we would overrun the buffer and
write the newline character outside the allotted space which can have
undefined consequences or result in a failure.
To fix this buffer overrun, ensure that there always is enough space
left for the newline character to be safely appended.

Make turning off unused power resources (after the enumeration of
devices and during system-wide resume from S3) more straightforward
by using the observation that the power resource state stored in
struct acpi_power_resource can be used to determine whether or not
the give power resource has any users.
Namely, when the state of the power resource is unknown, its _STA
method has never been evaluated (or the evaluation of it has failed)
and its _ON and _OFF methods have never been executed (or they have
failed to execute), so for all practical purposes it can be assumed
to have no users (or to be unusable). Therefore, instead of checking
the number of power resource users, it is sufficient to check if its
state is known.
Moreover, if the last known state of a given power resource is "off",
it is not necessary to turn it off, because it has been used to
initialize the power state or the wakeup power resources list of at
least one device and either its _STA method has returned 0 ("off"),
or its _OFF method has been successfully executed already.
Accordingly, modify acpi_turn_off_unused_power_resources() to do the
above checks (which are suitable for both uses of it) instead of
using the number of power resource users or evaluating its _STA
method, drop its argument (which is not useful any more) and update
its callers.
Also drop the users field from struct acpi_power_resource as it is
not useful any more.

Currently, there are two ways to check the state of an ACPI power
resource and they may not be consistent with each other. The first
one is to evaluate the power resource's _STA object and the other one
is to check its reference counter value. However, on some systems
the value returned by _STA may not be consistent with the value of
the power resource's reference counter (for example, on some systems
it returns the same value every time for certain power resources).
Moreover, evaluating _STA is unnecessary overhead for a power
resource for which it has been evaluated already or whose state is
otherwise known, because either the _ON or the _OFF method has been
executed for it.
For this reason, save the state of each power resource in its
struct acpi_power_resource object and use the saved value whenever
its state needs to be checked, except when its stats is unknown, in
which case the _STA method is evaluated for it and the value
returned by that method is saved as the last known state of
the power resource.
Moreover, drop the power resource _STA method evaluation from
acpi_add_power_resource(), so as to avoid doing that unnecessarily
for power resources that will never be used.

ACPI specification (e.g. ACPI 6.4, Section 7.2.2) the OS "may run
the _OFF method repeatedly, even if the resource is already off".
However, it turns out that some systems do not follow the
specification in this particular respect and that commit introduced
boot issues on them, so refine acpi_turn_off_unused_power_resources()
to only turn off power resources without any users after device

The ACPI fan device IDs are shared between the fan driver and the
device power management code. The former is modular, so it needs
to include the table of device IDs for module autoloading and the
latter needs that list to avoid attaching the generic ACPI PM domain
to fan devices (which doesn't make sense) possibly before the fan
driver module is loaded.
Unfortunately, that requires the list of fan device IDs to be
updated in two places which is prone to mistakes, so put it into

copy of it in case it needs to be updated again in the future.

Generally, the C-state latency is provided by the _CST method or
FADT, but some OEM platforms using AMD Picasso, Renoir, Van Gogh,
and Cezanne set the C2 latency greater than C3's which causes the
C2 state to be skipped.
That will block the core entering PC6, which prevents S0ix working
properly on Linux systems.
In other operating systems, the latency values are not validated and
this does not cause problems by skipping states.
To avoid this issue on Linux, detect when latencies are not an
arithmetic progression and sort them.
