Release the lock. ''Flags'' is the return value of AcquireLock. If you used this to store the interrupt state, now is the moment to use it. |

ACPI sometimes fires interrupt. ACPICA will take care of them. ''InterruptLevel'' is the IRQ number that ACPI will use. Handler is an internal function of ACPICA which handles interrupts. Context is the parameter to be past to the Handler. |
