From a8a2be949267cb0d1d933a92d9fb43eda4f4fe88 Mon Sep 17 00:00:00 2001 From: rajesh.shah@intel.com Date: Mon, 31 Oct 2005 16:20:07 -0800 Subject: [PATCH] pciehp: reduce dependence on ACPI Reduce the PCI Express hotplug driver's dependence on ACPI. We don't walk the acpi namespace anymore to build a list of bridges and devices. We go to ACPI only to run the _OSC or _OSHP methods to transition control of hotplug hardware from system BIOS to the hotplug driver, and to run the _HPP method to get hotplug device parameters like cache line size, latency timer and SERR/PERR enable from BIOS. Note that one of the side effects of this patch is that pciehp does not automatically enable the hot-added device or its DMA bus mastering capability now. It expects the device driver to do that. This may break some drivers and we will have to fix them as they are reported.
