From 6f09a9250a5d76c0765cd51a33e0a042e9761cfc Mon Sep 17 00:00:00 2001 From: John Keller Date: Tue, 30 Jan 2007 01:17:37 -0500 Subject: Altix: ACPI SSDT PCI device support Add SN platform support for running with an ACPI capable PROM that defines PCI devices in SSDT tables. There is a SSDT table for every occupied slot on a root bus, containing info for every PPB and/or device on the bus. The SSDTs will be dynamically loaded/unloaded at hotplug enable/disable. Platform specific information that is currently passed via a SAL call, will now be passed via the Vendor resource in the ACPI Device object(s) defined in each SSDT.
