Produces the CPU I/O PPI by using the services of the I/O Library.

Report Status Code Handler PEIM which produces general handlers and hook them onto the PEI status code router. This is the Report Status Code Handler PEIM that produces general handlers and hooks them onto the PEI status code router.

Fault Tolerant Write PEI Driver. This module installs gEdkiiFaultTolerantWriteGuid PPI to inform the check for FTW last write data has been done.

The Pre-EFI Initialization phase is invoked early in the boot flow.

Provides read, write and modify access to PCI configuration space in PEI phase. To follow PI specification, these services also support access to the unaligned PCI address.

Report Status Code Router is a PEIM that produces Report Status Code Handler PPI and Status Code PPI.

PCD PEIM produces PCD database to manage all dynamic PCD in PEI phase and install Pcd Ppi service. This version PCD PEIM depends on the external PCD database binary file, not built-in PCD database.

Implements ReadOnly Variable Services required by PEIM and installs PEI ReadOnly Varaiable2 PPI. This module implements ReadOnly Variable Services required by PEIM and installs PEI ReadOnly Varaiable2 PPI.

The Pre-EFI Initialization phase is invoked early in the boot flow.

The Pre-EFI Initialization phase is invoked early in the boot flow.

Last PEIM executed in PEI phase to load DXE Core from a Firmware Volume. This module produces a special PPI named the DXE Initial Program Load (IPL) PPI to discover and dispatch the DXE Foundation and components that are needed to run the DXE Foundation.

Initializes the Platform Configuration Database (PCD) values provided by Firmware Support Package (FSP).

PCD PEIM produces PCD database to manage all dynamic PCD in PEI phase and install Pcd Ppi service. This version PCD PEIM depends on the external PCD database binary file, not built-in PCD database.

The Pre-EFI Initialization phase is invoked early in the boot flow.

The Pre-EFI Initialization phase is invoked early in the boot flow.

PeiMain module is core module in PEI phase. It takes initializes memory, dispatches PEIM from discovered and then hands-off control to DxeIpl to load DXE core and enter DXE phase.

Last PEIM executed in PEI phase to load DXE Core from a Firmware Volume. This module produces a special PPI named the DXE Initial Program Load (IPL) PPI to discover and dispatch the DXE Foundation and components that are needed to run the DXE Foundation.

Initializes TPM 2.0 device and measure FVs in PEI phase This module will initialize TPM device, measure reported FVs and BIOS version.

Produces a PPI to indicate whether to lock TPM in PEI phase This module produces PEI_LOCK_PHYSICAL_PRESENCE_PPI to indicate whether TPM physical presence needs to be locked. It can be replaced by a platform specific module.

The Pre-EFI Initialization phase is invoked early in the boot flow.

The Pre-EFI Initialization phase is invoked early in the boot flow.

Set TPM device type This module initializes TPM device type based on variable and detection. NOTE: This module is only for reference only, each platform should have its own setup page.

Initializes TPM device and measures FVs in PEI phase This module will initialize TPM device, measure reported FVs and BIOS version. This module may also lock TPM physical presence and physicalPresenceLifetimeLock.
