ACPI: button: Enable wakeup GPEs for ACPI buttons at probe time

2026-05-25T07:52:34+00:00

Prior to commit 57c31e6d620f ("ACPI: scan: Use acpi_setup_gpe_for_wake() for buttons"), ACPI button wakeup GPEs having handler methods remained enabled after acpi_wakeup_gpe_init(), but currently they are not enabled because acpi_setup_gpe_for_wake() disables them. That causes function keys to stop working on some systems [1] and there may be other related issues elsewhere. To address that, make the ACPI button driver enable wakeup GPEs for ACPI buttons so long as they have handler methods. While this does not restore the old behavior exactly (the ACPI button driver needs to be bound to the button devices for the GPEs to be enabled), it should be sufficient to restore the missing functionality. For this purpose, introduce acpi_enable_gpe_cond() that enables a GPE if its dispatch type matches the supplied one and modify acpi_button_probe() to use that function for enabling the GPEs in question.

ACPICA: Allow to skip Global Lock initialization

2025-09-15T10:20:12+00:00

Introduce acpi_gbl_use_global_lock, which allows to skip the Global Lock initialization. This is useful for systems without Global Lock (such as loong_arch), so as to avoid error messages during boot phase: ACPI Error: Could not enable global_lock event (20240827/evxfevnt-182) ACPI Error: No response from Global Lock hardware, disabling lock (20240827/evglock-59) Link: https://github.com/acpica/acpica/commit/463cb0fe Signed-off-by: Huacai Chen Signed-off-by: Rafael J.
