- 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
