It is possible that users manually offlined CPUs via sysfs interface
and then started this utility. In this case we will not be able to get
package and die id of the those CPUs. So add an option to force online
if required for some commands.

parsing more robust
Make init_bios_attributes() ACPI object parsing more robust:
1. Always check that the type of the return ACPI object is package, rather
then only checking this for instance_id == 0
2. Check that the package has the minimum amount of elements which will
be consumed by the populate_foo_data() for the attr_type
Note/TODO: The populate_foo_data() functions should also be made more
robust. The should check the type of each of the elements matches the
type which they expect and in case of populate_enum_data()
obj->package.count should be passed to it as an argument and it should
re-check this itself since it consume a variable number of elements.

during suspend
Some devices send (duplicate) tablet-mode events when moved around even
though the mode has not changed; and they do this even when suspended.
Change the tablet-mode event handling when priv->wakeup_mode is set to
update the switch state in case it changed and then return immediately
(without calling pm_wakeup_hard_event()) to avoid spurious wakeups.

Due to a HW limitation, the Latency Tolerance Reporting (LTR) value
programmed in the Tiger Lake GBE controller is not large enough to allow
the platform to enter Package C10, which in turn prevents the platform from
achieving its low power target during suspend-to-idle. Ignore the GBE LTR
value on Tiger Lake. LTR ignore functionality is currently performed solely
by a debugfs write call. Split out the LTR code into its own function that
can be called by both the debugfs writer and by this work around.

The intel_pmc_core driver is mostly used as a debugging driver for Intel
platforms that support SLPS0 (S0ix). But the driver may also be used to
communicate actions to the PMC in order to ensure transition to SLPS0 on
some systems and architectures. As such the driver should be built on all
platforms it supports. Indicate this in the Kconfig. Also update the list
of supported features.

Stop reporting SW_DOCK events because this breaks suspend-on-lid-close.
SW_DOCK should only be reported for docking stations, but all the DSDTs in
my DSDT collection which use the intel-vbtn code, always seem to use this
for 2-in-1s / convertibles and set SW_DOCK=1 when in laptop-mode (in tandem
with setting SW_TABLET_MODE=0).
This causes userspace to think the laptop is docked to a port-replicator
and to disable suspend-on-lid-close, which is undesirable.
Map the dock events to KEY_IGNORE to avoid this broken SW_DOCK reporting.
Note this may theoretically cause us to stop reporting SW_DOCK on some
device where the 0xCA and 0xCB intel-vbtn events are actually used for
reporting docking to a classic docking-station / port-replicator but
I'm not aware of any such devices.
Also the most important thing is that we only report SW_DOCK when it
reliably reports being docked to a classic docking-station without any
false positives, which clearly is not the case here. If there is a
chance of reporting false positives then it is better to not report
SW_DOCK at all.

this.
2. There is no need for the pr_debug() calls sysfs_create_file() should

itself.

multiple times
During some of the error-exit paths it is possible that
release_attributes_data() will get called multiple times,
which results in exit_foo_attributes() getting called multiple
times.
Make it safe to call exit_foo_attributes() multiple times,
avoiding double-free()s in this case.
Note that release_attributes_data() really should only be called
once during error-exit paths. This will be fixed in a separate patch
and it is good to have the exit_foo_attributes() functions modified
this way regardless.

On some system the WMI GUIDs used by dell-wmi-sysman are present but there
are no enum type attributes, this causes init_bios_attributes() to return
-ENODEV, after which sysman_init() does a "goto fail_create_group" and then
calls release_attributes_data().
release_attributes_data() calls kset_unregister(wmi_priv.main_dir_kset);
but before this commit it was missing a "wmi_priv.main_dir_kset = NULL;"
statement; and after calling release_attributes_data() the sysman_init()
error handling does this:
if (wmi_priv.main_dir_kset) {
kset_unregister(wmi_priv.main_dir_kset);
wmi_priv.main_dir_kset = NULL;
}
Which causes a second kset_unregister(wmi_priv.main_dir_kset), leading to
a double-free, which causes a crash.
Add the missing "wmi_priv.main_dir_kset = NULL;" statement to
release_attributes_data() to fix this double-free crash.

balanced mode
Testing has shown that setting /sys/firmware/acpi/platform_profile to
"balanced" when /sys/bus/platform/devices/thinkpad_acpi/dytc_lapmode
reports 1, causes dytc_lapmode to get reset to 0 and then it becomes
stuck at 0 for aprox. 30 minutes even if the laptop is used on a lap.
Disabling CQL (when enabled) before issuing the DYTC_CMD_RESET to get
back to balanced mode and re-enabling it afterwards again, like the
code already does when switching to low-power / performance mode fixes
this.

On many recent ThinkPad laptops, there's a new LED next to the ESC key,
that indicates the FnLock status.
When the Fn+ESC combo is pressed, FnLock is toggled, which causes the
Media Key functionality to change, making it so that the media keys
either perform their media key function, or function as an F-key by
default. The Fn key can be used the access the alternate function at any
time.
With the current linux kernel, the LED doens't change state if you press
the Fn+ESC key combo. However, the media key functionality *does*
change. This is annoying, since the LED will stay on if it was on during
bootup, and it makes it hard to keep track what the current state of the
FnLock is.
This patch calls an ACPI function, that gets the current media key
state, when the Fn+ESC key combo is pressed. Through testing it was
discovered that this function causes the LED to update correctly to
reflect the current state when this function is called.
The relevant ACPI calls are the following:
\_SB_.PCI0.LPC0.EC0_.HKEY.GMKS: Get media key state, returns 0x603 if the FnLock mode is enabled, and 0x602 if it's disabled.
\_SB_.PCI0.LPC0.EC0_.HKEY.SMKS: Set media key state, sending a 1 will enable FnLock mode, and a 0 will disable it.

The Microsoft Surface Book series devices consist of a so-called
clipboard part (containing the CPU, touchscreen, and primary battery)
and a base part (containing keyboard, secondary battery, and optional
discrete GPU). These parts can be separated, i.e. the clipboard can be
detached and used as tablet.
This detachment process is initiated by pressing a button. On the
Surface Book 2 and 3 (targeted with this commit), the Surface Aggregator
Module (i.e. the embedded controller on those devices) attempts to send
a notification to any listening client driver and waits for further
instructions (i.e. whether the detachment process should continue or be
aborted). If it does not receive a response in a certain time-frame, the
detachment process (by default) continues and the clipboard can be
physically separated. In other words, (by default and) without a driver,
the detachment process takes about 10 seconds to complete.
This commit introduces a driver for this detachment system (called DTX).
This driver allows a user-space daemon to control and influence the
detachment behavior. Specifically, it forwards any detachment requests
to user-space, allows user-space to make such requests itself, and
allows handling of those requests. Requests can be handled by either
aborting, continuing/allowing, or delaying (i.e. resetting the timeout
via a heartbeat commend). The user-space API is implemented via the
/dev/surface/dtx miscdevice.
In addition, user-space can change the default behavior on timeout from
allowing detachment to disallowing it, which is useful if the (optional)
discrete GPU is in use.
Furthermore, this driver allows user-space to receive notifications
about the state of the base, specifically when it is physically removed
(as opposed to detachment requested), in what manner it is connected
(i.e. in reverse-/tent-/studio- or laptop-mode), and what type of base
is connected. Based on this information, the driver also provides a
simple tablet-mode switch (aliasing all modes without keyboard access,
i.e. tablet-mode and studio-mode to its reported tablet-mode).
An implementation of such a user-space daemon, allowing configuration of
detachment behavior via scripts (e.g. safely unmounting USB devices
connected to the base before continuing) can be found at [1].

device does not have the DVSEC region in its PCI config space so hard
code the discovery table data in the driver. Also requires a fix for DG1
in the Telemetry driver for how the ACCESS_TYPE field is used.

Some products will be available that have PMT capabilities that are not
supported. Remove the warnings in this instance to avoid nuisance messages
and confusion.
Also return an error code for capabilities that are disabled by quirk to
prevent them from keeping the driver loaded if only disabled capabilities
are found.

The old device property API (device_add_properties()) is
going to be removed. Replacing the it with the software node
API equivalent, device_create_managed_software_node().

The driver core ignores the return value of struct bus_type::remove()
(and so wmi_dev_remove()) because there is only little that can be done.
To simplify the quest to make this function return void, let struct
wmi_driver::remove() return void, too. All implementers of this callback
return 0 already and this way it should be obvious to driver authors
that returning an error code is a bad idea.

A few x86 platform drivers use ACPI_DEBUG_PRINT() or ACPI_EXCEPTION()
for printing messages, but that is questionable, because those macros
belong to ACPICA and they should not be used elsewhere. In addition,
ACPI_DEBUG_PRINT() requires special enabling to allow it to actually
print the message, which is a nuisance, and the _COMPONENT symbol
generally needed for that is not defined in any of the files in
question.
For this reason, replace the ACPI_DEBUG_PRINT() in lg-laptop.c with
pr_debug() and the one in xo15-ebook.c with acpi_handle_debug()
(with the additional benefit that the source object can be identified
more easily after this change).
Also drop the ACPI_MODULE_NAME() definitions that are only used by
the ACPICA message printing macros from those files and from wmi.c
and surfacepro3_button.c (while at it).

Like a few other system the Lenovo ThinkPad X1 Tablet Gen 2 miss the
HEBC method, which prevent the power button from working. Add a quirk
to enable the button array on this system family and fix the power
button.

Those events occur when a keyboard cover is attached to a ThinkPad
X1 Tablet series device. Typically, they are used to switch from normal
to tablet mode in userspace; e.g., to offer touch keyboard choices when
focus goes to a text box and no keyboard is attached, or to enable
autorotation of the display according to the builtin orientation sensor.
intel-vtbn already recognizes those events. To avoid sending duplicate
events to userspace, they are simply ignored. Thus, this patch only
avoids warnings about unknown and unhandled HKEYs 0x4012 and 0x4013.
For more information about the background and potential improvements for
different types of attachment options, such as the Pico cartridge dock
module, see
