From 424600f9706b20a8a33ad928d3d0326bd88679bc Mon Sep 17 00:00:00 2001 From: "rajesh.shah@intel.com" Date: Thu, 13 Oct 2005 12:05:38 -0700 Subject: [PATCH] shpchp: reduce dependence on ACPI Reduce the SHPC hotplug driver's dependence on ACPI. We don't walk the acpi namespace anymore to build a list of bridges and devices. The remaining interaction with ACPI is to run the _OSHP method to transition control of hotplug hardware from system BIOS to the shpc 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 shpchp does not enable the hot-added device or its DMA bus mastering automatically 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.
