ACPI: video: Fix acpi_video_handles_brightness_key_presses()
Commit
3a0cf7ab8df3 ("ACPI: video: Change how we determine if brightness
key-presses are handled") made acpi_video_handles_brightness_key_presses()
report false when none of the ACPI Video Devices support backlight control.
But it turns out that at least on a Dell Inspiron N4010 there is no ACPI
backlight control, yet brightness hotkeys are still reported through
the ACPI Video Bus; and since acpi_video_handles_brightness_key_presses()
now returns false, brightness keypresses are now reported twice.
To fix this rename the has_backlight flag to may_report_brightness_keys and
also set it the first time a brightness key press event is received.
Depending on the delivery of the other ACPI (WMI) event vs the ACPI Video
Bus event this means that the first brightness key press might still get
reported twice, but all further keypresses will be filtered as before.
Note that this relies on other drivers reporting brightness key events
calling acpi_video_handles_brightness_key_presses() when delivering
the events (rather then once during driver probe). This is already
required and documented in include/acpi/video.h:
/*
* Note: The value returned by acpi_video_handles_brightness_key_presses()
* may change over time and should not be cached.
*/

This is a problem when the old global pm_power_off handler would later

The old global pm_power_off handler gets run with a priority of
SYS_OFF_PRIO_DEFAULT which is lower then SYS_OFF_PRIO_FIRMWARE, causing

Switch the registering of efi_power_off over to register_sys_off_handler()
with a priority of SYS_OFF_PRIO_FIRMWARE + 1 so that it will run before
acpi_power_off() as before.
Note since the new sys-off-handler code will try all handlers in

platform/x86: ISST: PUNIT device mapping with Sub-NUMA clustering
On a multiple package system using Sub-NUMA clustering, there is an issue
in mapping Linux CPU number to PUNIT PCI device when manufacturer decided
to reuse the PCI bus number across packages. Bus number can be reused as
long as they are in different domain or segment. In this case some CPU
will fail to find a PCI device to issue SST requests.
When bus numbers are reused across CPU packages, we are using proximity
information by matching CPU numa node id to PUNIT PCI device numa node
id. But on a package there can be only one PUNIT PCI device, but multiple
numa nodes (one for each sub cluster). So, the numa node ID of the PUNIT
PCI device can only match with one numa node id of CPUs in a sub cluster
in the package.
Since there can be only one PUNIT PCI device per package, if we match
with numa node id of any sub cluster in that package, we can use that
mapping for any CPU in that package. So, store the match information
in a per package data structure and return the information when there
is no match.
While here, use defines for max bus number instead of hardcoding.

platform/surface: Add KIP/POS tablet-mode switch driver
Add a driver providing a tablet-mode switch input device for Microsoft
Surface devices using the Surface Aggregator KIP subsystem (to manage
detachable peripherals) or POS subsystem (to obtain device posture
information).
The KIP (full name unknown, abbreviation found through reverse
engineering) subsystem is used on the Surface Pro 8 and Surface Pro X to
manage the keyboard cover. Among other things, it provides information
on the positioning (posture) of the cover (closed, laptop-style,
detached, folded-back, ...), which can be used to implement an input
device providing the SW_TABLET_MODE event. Similarly, the POS (posture
information) subsystem provides such information on the Surface Laptop
Studio, with the difference being that the keyboard is not detachable.
As implementing the tablet-mode switch for both subsystems is largely
similar, the driver proposed in this commit, in large, acts as a generic
tablet mode switch driver framework for the Surface Aggregator Module.
Specific implementations using this framework are provided for the KIP
and POS subsystems, adding tablet-mode switch support to the
aforementioned devices.
A few more notes on the Surface Laptop Studio:
A peculiarity of the Surface Laptop Studio is its "slate/tent" mode
(symbolized: user> _/\). In this mode, the screen covers the keyboard
but leaves the touchpad exposed. This is essentially a mode in-between
tablet and laptop, and it is debatable whether tablet-mode should be
enabled in this mode. We therefore let the user decide this via a module
parameter.
In particular, tablet-mode may bring up the on-screen touch keyboard
more easily, which would be desirable in this mode. However, some
user-space software currently also decides to disable keyboard and, more
importantly, touchpad input, while the touchpad is still accessible in
the "slate/tent" mode. Furthermore, this mode shares its identifier with
"slate/flipped" mode where the screen is flipped 180° and the keyboard
points away from the user (symbolized: user> /_). In this mode we would
like to enable auto-rotation, something that user-space software may
only do when tablet-mode is enabled. We therefore default to the
slate-mode enabling the tablet-mode switch.

platform/surface: aggregator_registry: Add support for keyboard cover on Surface Pro 8
Add support for the detachable keyboard cover on the Surface Pro 8.
The keyboard cover on the Surface Pro 8 is, unlike the keyboard covers
of earlier Surface Pro generations, handled via the Surface System
Aggregator Module (SSAM). The keyboard and touchpad (as well as other
HID input devices) of this cover are standard SSAM HID client devices
(just like keyboard and touchpad on e.g. the Surface Laptop 3 and 4),
however, some care needs to be taken as they can be physically detached
(similarly to the Surface Book 3). Specifically, the respective SSAM
client devices need to be removed when the keyboard cover has been
detached and (re-)initialized when the keyboard cover has been
(re-)attached.
On the Surface Pro 8, detachment of the keyboard cover (and by extension
its devices) is managed via the KIP subsystem. Therefore, said devices
need to be registered under the KIP device hub, which in turn will
remove and re-create/re-initialize those devices as needed.

Add a Surface System Aggregator Module (SSAM) client device hub for

The KIP subsystem (full name unknown, abbreviation has been obtained

SSAM client devices. Specifically, it manages HID input devices
contained in the detachable keyboard cover of the Surface Pro 8 and
Surface Pro X.
The KIP subsystem handles a single group of devices (e.g. all devices
contained in the keyboard cover) and cannot handle devices individually.
Thus we model it as a client device hub, which (hot-)removes all devices
contained under it once removal of the hub (e.g. keyboard cover) has
been detected and (re-)adds all devices once the physical hub device has
been (re-)attached. To do this, use the previously generified SSAM

The Surface Pro 8 has a new type-cover with keyboard and touchpad, which
is managed via the KIP/0x0e subsystem. The general procedure is the
same, but with slightly different events and setup. To make
implementation of the KIP hub easier and prevent duplication, generify
the parts of the base hub that we can use for the KIP hub (or any
potential future subsystem hubs).
This also switches over to use the newly introduced "hot-remove"
functionality, which should prevent communication issues when devices
have been detached.
Lastly, also drop the undocumented and unused sysfs "state" attribute of
the base hub. It has at best been useful for debugging.

block and slow down device removal and even cause issues when the

While we already remove a device as soon as we detect its (hot-)removal,
the corresponding device driver may still attempt to communicate with
the device during teardown. This is especially critical as communication
failure may also extend to disabling of events, which is typically done
at that stage.
Add a flag to allow marking devices as hot-removed. This can then be

platform/x86: hp-wmi: Resolve WMI query failures on some devices
WMI queries fail on some devices where the ACPI method HWMC
unconditionally attempts to create Fields beyond the buffer
if the buffer is too small, this breaks essential features
such as power profiles:
CreateByteField (Arg1, 0x10, D008)
CreateByteField (Arg1, 0x11, D009)
CreateByteField (Arg1, 0x12, D010)
CreateDWordField (Arg1, 0x10, D032)
CreateField (Arg1, 0x80, 0x0400, D128)
In cases where args->data had zero length, ACPI BIOS Error
(bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit
offset/length 128/8 exceeds size of target Buffer (128 bits)
(
20211217/dsopcode-198) was obtained.
ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit
offset/length 136/8 exceeds size of target Buffer (136bits)
(
20211217/dsopcode-198)
The original code created a buffer size of 128 bytes regardless if
the WMI call required a smaller buffer or not. This particular
behavior occurs in older BIOS and reproduced in OMEN laptops. Newer
BIOS handles buffer sizes properly and meets the latest specification
requirements. This is the reason why testing with a dynamically
allocated buffer did not uncover any failures with the test systems at
hand.
This patch was tested on several OMEN, Elite, and Zbooks. It was
confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN
Laptop 15-ek0xxx. No problems were reported when testing on several Elite
and Zbooks notebooks.
