/** @file
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
