Add module parameters to allow setting the hw_rfkill_switch and
set_fn_lock_led feature flags for testing these on laptops which are not
on the DMI-id based allow lists for these 2 flags.

Yoga laptops
Commit 3ae86d2d4704 ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock
LED") uses the WMI event-id for the fn-lock event on some Legion 5 laptops
to manually toggle the fn-lock LED because the EC does not do it itself.
However, the same WMI ID is also sent on some Yoga laptops. Here, setting
the fn-lock state is not valid behavior, and causes the EC to spam
interrupts until the laptop is rebooted.
Add a set_fn_lock_led_list[] DMI-id list and only enable the workaround to
manually set the LED on models on this list.

Add device nodes to enable support for battery and charger status, the
ACPI platform profile, as well as internal and type-cover HID devices
(including sensors, touchpad, keyboard, and other miscellaneous devices)
on the Surface Pro 9.
This does not include support for a tablet-mode switch yet, as that is
now handled via the POS subsystem (unlike the Surface Pro 8, where it is
handled via the KIP subsystem) and therefore needs further changes.
While we're at it, also add the missing comment for the Surface Pro 8.

Currently, we check any received packet whether we have already seen it
previously, regardless of the packet type (sequenced / unsequenced). We
do this by checking the sequence number. This assumes that sequence
numbers are valid for both sequenced and unsequenced packets. However,
this assumption appears to be incorrect.
On some devices, the sequence number field of unsequenced packets (in
particular HID input events on the Surface Pro 9) is always zero. As a
result, the current retransmission check kicks in and discards all but
the first unsequenced packet, breaking (among other things) keyboard and
touchpad input.
Note that we have, so far, only seen packets being retransmitted in
sequenced communication. In particular, this happens when there is an
ACK timeout, causing the EC (or us) to re-send the packet waiting for an
ACK. Arguably, retransmission / duplication of unsequenced packets
should not be an issue as there is no logical condition (such as an ACK
timeout) to determine when a packet should be sent again.
Therefore, remove the retransmission check for unsequenced packets
entirely to resolve the issue.

The current logic in the Intel PMC driver will forcefully attach it
when detecting any CPU on the intel_pmc_core_platform_ids array,
even if the matching ACPI device is not present.
There's no checking in pmc_core_probe() to assert that the PMC device
is present, and hence on virtualized environments the PMC device
probes successfully, even if the underlying registers are not present.
Before commit 21ae43570940 ("platform/x86: intel_pmc_core: Substitute PCI
with CPUID enumeration") the driver would check for the presence of a
specific PCI device, and that prevented the driver from attaching when
running virtualized.
Fix by only forcefully attaching the PMC device when not running
virtualized. Note that virtualized platforms can still get the device
to load if the appropriate ACPI device is present on the tables
provided to the VM.
Make an exception for the Xen initial domain, which does have full
hardware access, and hence can attach to the PMC if present.

"The most important fixes here are a set of fixes for the ACPI
backlight detection refactor which landed in 6.1.
These fix regressions reported on some laptop models by making
acpi_video_backlight_use_native() always return true for now, which in

avoid the (known) regressions.

- ACPI: video: Fix regressions from 6.1 backlight refactor by making
acpi_video_backlight_use_native() always return true for now
- Misc other bugfixes and HW id additions"

We have accessing P2SB from a very few places for quite known hardware.
When a new SoC appears in intel-family.h it's not obvious that it needs
to be added to p2sb.c as well. Instead, provide default BDF and refactor
p2sb_get_devfn() to always succeed. If in the future we would need to
exclude something, we may add a list of unsupported IDs.
Without this change the iTCO on Intel Comet Lake SoCs became unavailable:

After upgrading BIOS to U82 01.02.01 Rev.A, the console is flooded
strange char "^@" which printed out every second and makes login
nearly impossible. Also the below messages were shown both in console
and journal/dmesg every second:
usb 1-3: Device not responding to setup address.
usb 1-3: device not accepting address 4, error -71
usb 1-3: device descriptor read/all, error -71
usb usb1-port3: unable to enumerate USB device
Wifi is soft blocked by checking rfkill. When unblocked manually,
after few seconds it would be soft blocked again. So I was suspecting
something triggered rfkill to soft block wifi. At the end it was
fixed by removing hp_wmi module.
The root cause is the way hp-wmi driver handles command 1B on
post-2009 BIOS. In pre-2009 BIOS, command 1Bh return 0x4 to indicate
that BIOS no longer controls the power for the wireless devices.

generic_acpi_laptop_init()
Currently the return value of 'sub_driver->init' is not checked. If
sparse_keymap_setup() called in the init function fails, 'generic_
inputdev' is freed, then it will lead a UAF when using it in generic_
acpi_laptop_init(). Fix it by checking the return value and setting
generic_inputdev to NULL after free, so as to avoid double free it.
The error code in generic_subdriver_init() is always negative, so the

commit b0c07116c894 ("platform/x86: amd-pmc: Avoid reading SMU version at
probe time") adjusted the behavior for amd-pmc to avoid reading the SMU
version at startup but rather on first use to improve boot time.
However the SMU version is also used to decide whether to place a timer
based wakeup in the OS_HINT message. If the idlemask hasn't been read
before this message was sent then the SMU version will not have been
cached.
Ensure the SMU version has been read before deciding whether or not to
run this codepath.

The second, not present fan always reads 65535 (-1 in 16 bit signed),
ignore fans which report 65535 to avoid reporting the non present fan.

On PREEMPT_RT enabled kernels the demultiplex interrupt handler is force
threaded and runs with interrupts enabled. The invocation of
generic_handle_irq() with interrupts enabled triggers a lockdep warning due
to a non-irq safe lock acquisition.
Instead of disabling interrupts on the driver level, use
generic_handle_domain_irq_safe().

The for_each_acpi_consumer_dev() takes a reference to the iterator
and if we break a loop we must drop that reference. This usually
happens when error handling is involved. However it's not the case
for skl_int3472_fill_clk_pdata().
Don't leak reference on error by dropping it properly.

The idle mask is dumped during the "prepare" and "restore" stage
right now, which helps to demonstrate issues only related to the
first s2idle entry.
If the system has entered s2idle once, but was woken up never
breaking the s2idle loop but also never went back to sleep we
might still have another issue to deal with however.
Move the dynamic debugging message here so that we'll catch it on
each iteration.

To work around a misbehavior of the compiler's ability to see into
composite flexible array structs (as detailed in the coming memcpy()
hardening series[1]), split the memcpy() of the header and the payload
so no false positive run-time overflow warning will be generated.

It is observed that when thinkpad_acpi driver loads before amd-pmf
driver, thinkpad_acpi driver sends the AMT "on" event and the request
immediately will be part of the PMF BIOS "pending requests".
With the current amd-pmf code, as soon as the amd-pmf driver gets
probed, it calls apmf_acpi_init() where the notify handler will be
installed. Handler callback would call amd_pmf_handle_amt() where the
amd_pmf_set_automode() shall update the auto-mode thermals.
In this case, the auto-mode config_store shall have "zeros", as the
auto mode init gets called during the later stage.
To fix this, change the order of the acpi notifer install and call it
after the auto mode initialization is done.

CnQF (a.k.a Cool and Quiet Framework) extends the static slider concept.
PMF dynamically manages system power limits and fan policy based on system
power trends which is representative of workload trend.
Static slider and CnQF controls are mutually exclusive for system power
budget adjustments. CnQF supports configurable number of modes which can
be unique for AC and DC. Every mode is representative of a system state
characterized by unique steady state and boost behavior.
OEMs can configure the different modes/system states and how the
transition to a mode happens. Whether to have CnQF manage system power
budget dynamically in AC or DC or both is also configurable. Mode changes
due to CnQF don't result in slider position change.
The default OEM values are obtained after evaluating the PMF ACPI function
idx 11 & 12 for AC and DC respectively. Whether to turn ON/OFF by default
is guided by a "flag" passed by the OEM BIOS.

Without CONFIG_DEBUG_FS, the following build error occurs:
drivers/platform/x86/amd/pmc.c:984:17: error: use of undeclared identifier 'pmc_groups'; did you mean 'set_groups'?
.dev_groups = pmc_groups,
^~~~~~~~~~
set_groups
./include/linux/cred.h:65:13: note: 'set_groups' declared here
extern void set_groups(struct cred *, struct group_info *);
^
drivers/platform/x86/amd/pmc.c:984:17: error: incompatible pointer types initializing 'const struct attribute_group **' with an expression of type 'void (struct cred *, struct group_info *)' [-Werror,-Wincompatible-pointer-types]
.dev_groups = pmc_groups,
^~~~~~~~~~
2 errors generated.
pmc_groups was only defined inside a CONFIG_DEBUG_FS block but
commit 7f1ea75d499a ("platform/x86/amd: pmc: Add sysfs files for SMU")
intended for these sysfs files to be available outside of debugfs.
Shuffle the necessary functions out of the CONFIG_DEBUG_FS block so that
the file always builds.
Fixes: 7f1ea75d499a ("platform/x86/amd: pmc: Add sysfs files for SMU")

Add scancodes reported by the touchpad on/off button. The actual disabling
and enabling is done in hardware, and this just reports that change to
userspace.

By swapping the definition of skl_int3472_discrete_remove() and
skl_int3472_discrete_probe() the forward declaration of the former can
be dropped. This is a good thing as it removes code duplication.
