# Module produces PciCfgPpi2 on top of PciCfgPpi. It also updates the
|
|
# PciCfg2Ppi pointer in the EFI_PEI_SERVICES upon a installation of
|
|
# EcpPeiPciCfgPpi.
|
|
#
|
|
# EcpPeiPciCfgPpi is installed by a framework module which
|
|
# produce PciCfgPpi originally. Such framework module is updated based on the
|
|
# following rule to install EcpPeiPciCfgPpi instead of updating the PciCfg pointer
|
|
# in the Framework PeiServicesTable:
|
|
#
|
|
# Search pattern:
|
|
# PeiServices->PciCfg = <*>;
|
|
# Replace pattern:
|
|
# {
|
|
# static EFI_PEI_PPI_DESCRIPTOR gEcpPeiPciCfgPpiList = {
|
|
# (EFI_PEI_PPI_DESCRIPTOR_PPI | EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST),
|
|
# &gEcpPeiPciCfgPpiGuid,
|
|
# <*>
|
|
# };
|
|
# (**PeiServices).InstallPpi (PeiServices, &gEcpPeiPciCfgPpiList);
|
|
# }
|
|
#
|
|
# In addition, the PeiServicesTable definition in PeiApi.h is updated to
|
|
#
|
|
# struct _EFI_PEI_SERVICES {
|
|
# EFI_TABLE_HEADER Hdr;
|
|
# ...
|
|
#
|
|
# //
|
|
# // Pointer to PPI interface
|
|
# //
|
|
# #if (PI_SPECIFICATION_VERSION < 0x00010000)
|
|
#
|
|
# PEI_CPU_IO_PPI *CpuIo;
|
|
# ECP_PEI_PCI_CFG_PPI *PciCfg; //Changed.
|
|
# #else
|
|
# ...
|
|
# #endif
|
|
#
|
|
# };
|
|
#
|
|
# This change enable the detection of code segment which invokes PeiServices->PciCfg->Modify.
|
|
# Such code causes a build break as ECP_PEI_PCI_CFG_PPI does not has "Modify" field.
|
|
# This should be updated to a call to PeiLibPciCfgModify as shown below:
|
|
#
|
|
# Search pattern:
|
|
# *->Modify(<*>);
|
|
# Replace pattern:
|
|
# PeiLibPciCfgModify(<*>);
|
|
#
|
|
# PIWG's PI specification replaces Inte's EFI Specification 1.10.
|
|
# EFI_PEI_PCI_CFG_PPI defined in Inte's EFI Specification 1.10 is replaced by
|
|
# EFI_PEI_PCI_CFG2_PPI in PI 1.0.
|
|
# This module produces PciCfgPpi on top of PciCfgPpi2. This module is used on platform when both of
|
|
# these two conditions are true:
|
|
# 1) Framework module present that produces PCI CFG PPI AND
|
|
# 2) PI module that produces PCI CFG2 is not present
|
|
|
|
#
|
|
# PEIM to provide the Variable functionality.
