[PATCH 3/3] ACPI / ACPICA: Disable GPEs during initialization

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Rafael J. Wysocki <rjw@xxxxxxx>

GPEs with corresponding _Lxx/_Exx control methods need to be disabled
during initialization in case they have been enabled by the BIOS, so
that they don't fire up until they are enabled by acpi_update_gpes().
