From aa0ebec9cfb8a3fab966db75ac21d05a43f312a1 Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Fri, 9 Nov 2007 10:51:01 +0900 Subject: [IA64] Fix iosapic interrupt delivery mode for CPE If "CPEI Processor Override" bit is not set in "Platform Interrupt Source Flags" in "Platform Interrupt Sources Structure" in ACPI MADT, the target processor of CPEI is restricted to a specific CPU. Because of this, the delivery mode for CPEI should be IOSAPIC_FIXED.
