Commit 98f30d0e ("ACPI: power: Switch to sys-off handler API") switched the ACPI sleep code from directly setting the old global pm_power_off handler to using the new register_sys_off_handler() mechanism with a priority of SYS_OFF_PRIO_FIRMWARE. This is a problem when the old global pm_power_off handler would later be overwritten, such as done by the late_initcall(efi_shutdown_init): if (efi_poweroff_required()) pm_power_off = efi_power_off; 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 acpi_power_off() to run first, changing the behavior from before the ACPI sleep code switched to the new register_sys_off_handler(). 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 priority order, there is no more need for the EFI code to store and call the original pm_power_off handler.

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. Signed-off-by:

Maximilian Luz authored
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.

On some Panasonic models the volume up/down/mute keypresses get reported both through the Panasonic ACPI HKEY interface as well as through the atkbd device. Filter out the atkbd scan-codes for these to avoid reporting presses twice. Note normally we would leave the filtering of these to userspace by mapping the scan-codes to KEY_UNKNOWN through /lib/udev/hwdb.d/60-keyboard.hwdb. However in this case that would cause regressions since we were filtering the Panasonic ACPI HKEY events before, so filter these in the kernel.
