/** @file
|

|
|
This file declares Recovery Module PPI. This PPI is used to find and load the
|
||
|
|
recovery files.
|
||
|
|
|
||
|
|
A module that produces this PPI has many roles and is responsible for the following:
|
||
|
|
-# Calling the driver recovery PPI EFI_PEI_DEVICE_RECOVERY_MODULE_PPI.
|
||
|
|
GetNumberRecoveryCapsules() to determine if one or more DXE recovery
|
||
|
|
entities exist.
|
||
|
|
-# If no capsules exist, then performing appropriate error handling.
|
||
|
|
-# Allocating a buffer of MaxRecoveryCapsuleSize as determined by
|
||
|
|
EFI_PEI_DEVICE_RECOVERY_MODULE_PPI.GetRecoveryCapsuleInfo() or
|
||
|
|
larger.
|
||
|
|
-# Determining the policy in which DXE recovery capsules are loaded.
|
||
|
|
-# Calling the driver recovery PPI EFI_PEI_DEVICE_RECOVERY_MODULE_PPI.
|
||
|
|
LoadRecoveryCapsule() for capsule number x.
|
||
|
|
-# If the load failed, performing appropriate error handling.
|
||
|
|
-# Performing security checks for a loaded DXE recovery capsule.
|
||
|
|
-# If the security checks failed, then logging the failure in a data HOB.
|
||
|
|
-# If the security checks failed, then determining the next
|
||
|
|
EFI_PEI_DEVICE_RECOVERY_MODULE_PPI.LoadRecoveryCapsule()capsule number;
|
||
|
|
otherwise, go to step 11.
|
||
|
|
-# If more DXE recovery capsules exist, then go to step 5; otherwise, perform
|
||
|
|
error handling.
|
||
|
|
-# Decomposing the capsule loaded by EFI_PEI_DEVICE_RECOVERY_MODULE_PPI.
|
||
|
|
LoadRecoveryCapsule() into its components. It is assumed that the path
|
||
|
|
parameters are redundant for recovery and Setup parameters are either
|
||
|
|
redundant or canned.
|
||
|
|
-# Invalidating all HOB entries for updateable firmware volume entries.
|
||
|
|
This invalidation prevents possible errant drivers from being executed.
|
||
|
|
-# Updating the HOB table with the recovery DXE firmware volume information
|
||
|
|
generated from the capsule decomposition.
|
||
|
|
-# Returning to the PEI Dispatcher.
