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:

Split out subsystem device hub drivers into their own module. This allows us to load the hub drivers separately from the registry, which will help future DT/OF support. While doing so, also remove a small bit of code duplication. Signed-off-by:

Move helper functions for client device registration to the core module. This simplifies addition of future DT/OF support and also allows us to split out the device hub drivers into their own module. At the same time, also improve device node validation a bit by not silently skipping devices with invalid device UID specifiers. Further, ensure proper lifetime management for the firmware/software nodes associated with the added devices. Signed-off-by:

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.

Some systems have an ACPI video bus but not ACPI video devices with backlight capability. On these devices brightness key-presses are (logically) not reported through the ACPI video bus. Change how acpi_video_handles_brightness_key_presses() determines if brightness key-presses are handled by the ACPI video driver to avoid vendor specific drivers/platform/x86 drivers filtering out their brightness key-presses even though they are the only ones reporting these presses.
