From 574bb8b749fc6841f35293fd89c3496baeef900c Mon Sep 17 00:00:00 2001 From: vanjeff Date: Tue, 7 Jul 2009 07:09:31 +0000 Subject: Add IncompatiblePciDeviceSupportDxe module in IntelFrameworkModulePkg. This module provided one typical incompatible PCI device list to be one template and install EFI incompatible PCI device support protocol. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@8783 6f19259b-4bc3-4df7-8a09-765794883524 --- .../IncompatiblePciDeviceSupport.c | 388 +++++++++++++++++++++ .../IncompatiblePciDeviceSupportDxe.inf | 47 +++ .../Bus/Pci/PciBusDxe/PciEnumeratorSupport.c | 16 +- 3 files changed, 443 insertions(+), 8 deletions(-) create mode 100644 IntelFrameworkModulePkg/Bus/Pci/IncompatiblePciDeviceSupportDxe/IncompatiblePciDeviceSupport.c create mode 100644 IntelFrameworkModulePkg/Bus/Pci/IncompatiblePciDeviceSupportDxe/IncompatiblePciDeviceSupportDxe.inf (limited to 'IntelFrameworkModulePkg/Bus/Pci') diff --git a/IntelFrameworkModulePkg/Bus/Pci/IncompatiblePciDeviceSupportDxe/IncompatiblePciDeviceSupport.c b/IntelFrameworkModulePkg/Bus/Pci/IncompatiblePciDeviceSupportDxe/IncompatiblePciDeviceSupport.c new file mode 100644 index 0000000000..9f81f1de3a --- /dev/null +++ b/IntelFrameworkModulePkg/Bus/Pci/IncompatiblePciDeviceSupportDxe/IncompatiblePciDeviceSupport.c @@ -0,0 +1,388 @@ +/** @file + This module is one template module for Incompatible PCI Device Support protocol. + It includes one incompatile pci devices list template. + + Incompatible PCI Device Support protocol allows the PCI bus driver to support + resource allocation for some PCI devices that do not comply with the PCI Specification. + +Copyright (c) 2009, Intel Corporation +All rights reserved.
