[PATCH 16/22] ACPICA: Add GPE support for dynamically loaded ACPI tables

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

 



From: Bob Moore <robert.moore@xxxxxxxxx>

For all GPEs, including FADT-based and GPE Block Devices, execute
any _PRW methods in the new table, and process any _Lxx/_Exx GPE
methods in the new table. Any runtime GPE that is referred to
by an _Lxx/_Exx method in the new table is immediately enabled.
ACPICA BZ 833.
