From ed206fac87d65917280b6c3edd3f01125d4095c9 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Mon, 27 Oct 2008 14:01:02 -0700 Subject: ACPI: bugfix reporting of event handler status Introduce a new flag showing whether the event has an event handler/method. For all the GPEs and Fixed Events, 1. ACPI_EVENT_FLAG_HANDLE is cleared, it's an "invalid" ACPI event. 2. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_DISABLE are set, it's "disabled". 3. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_ENABLE are set, it's "enabled". 4. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_WAKE_ENABLE are set, it's "wake_enabled". Among other things, this prevents incorrect reporting of ACPI events as being "invalid" when it's really just (temporarily) "disabled".
