From ba886cd4ac957608777fbc8d137f6b9f0450e775 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Thu, 10 Apr 2008 19:06:37 +0400 Subject: ACPICA: Update for mutiple global lock acquisitions by same thread Allows AcpiAcquireGlobalLock external interface to be called multiple times by the same thread. Allows use of AML fields that require the global lock while the running AML is already holding the global lock.

Current events that are defined are LOAD and UNLOAD. These interfaces allow the host to track ACPI tables as they are dynamically loaded and unloaded.
