Subject: [patch 11/12] Export the interface to get PCI id for an ACPI handle
Date: Fri, 18 Mar 2005 14:20:17 -0800 [thread overview]
Message-ID: <20050318142017.K1145@unix-os.sc.intel.com> (raw)
In-Reply-To: <20050318133856.A878@unix-os.sc.intel.com>; from rajesh.shah@intel.com on Fri, Mar 18, 2005 at 01:38:57PM -0800
Export an acpi interface to get PCI domain/bus/devfn information
from the corresponding namespace handle. Used by acpiphp code
to transpate the device handle of the hot-plugged root bridge to
the corresponding pci location information.
