| * ACPI: platform: Hide ACPI_PLATFORM_PROFILE optionMaximilian Luz2021-02-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | The ACPI_PLATFORM_PROFILE option essentially provides a library and not really an independent module. Thus it seems to be more user-friendly to hide this option and simply make drivers depending on it select it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tasklets have long been deprecated as being too heavy on the system by running in irq context - and this is not a performance critical path. If a higher priority process wants to run, it must wait for the tasklet to finish before doing so. A more suitable equivalent is to converted to threaded irq instead and deal with the signaled pipes in task context.

On those devices, the dGPU is contained in the base, which can be separated from the tablet part (containing CPU and touchscreen) while the device is running. It (in general) is presented as/behaves like a standard PCIe hot-plug capable device, however, this device can also be put into D3cold. In D3cold, the device itself is turned off and can thus not submit any standard PCIe hot-plug events. To properly detect hot-(un)plugging while the dGPU is in D3cold, out-of-band signaling is required. Without this, the device state will only get updated during the next bus-check, eg. via a manually issued lspci call. This commit adds a driver to handle out-of-band PCIe hot-(un)plug events on Microsoft Surface devices. On those devices, said events can be detected via GPIO interrupts, which are then forwarded to the corresponding ACPI DSM calls by this driver. The DSM then takes care of issuing the appropriate bus-/device-check, causing the PCI core to properly pick up the device change.
