From fd58e55fcf5568e51da2ed54d7acd049c3fdb184 Mon Sep 17 00:00:00 2001 From: Mark Maule Date: Mon, 10 Apr 2006 21:17:48 -0500 Subject: [PATCH] PCI: msi abstractions and support for altix Abstract portions of the MSI core for platforms that do not use standard APIC interrupt controllers. This is implemented through a new arch-specific msi setup routine, and a set of msi ops which can be set on a per platform basis.
