EFI_OUT_OF_RESOURCES There is not enough heap to allocate the requested size.

typedef VOID(EFIAPI * EFI_PEI_COPY_MEM)(IN VOID *Destination, IN VOID *Source, IN UINTN Length)

typedef VOID(EFIAPI * EFI_PEI_CORE_ENTRY_POINT)(IN CONST EFI_SEC_PEI_HAND_OFF *SecCoreData, IN CONST EFI_PEI_PPI_DESCRIPTOR *PpiList)

The entry point of PEI Foundation.

This function is the entry point for the PEI Foundation, which allows the SEC phase to pass information about the stack, temporary RAM and the Boot Firmware Volume. In addition, it also allows the SEC phase to pass services and data forward for use during the PEI phase in the form of one or more PPIs. There is no limit to the number of additional PPIs that can be passed from SEC into the PEI Foundation. As part of its initialization phase, the PEI Foundation will add these SEC-hosted PPIs to its PPI database such that both the PEI Foundation and any modules can leverage the associated service calls and/or code in these early PPIs.

Parameters:
SecCoreData Points to a data structure containing information about the PEI core's operating environment, such as the size and location of temporary RAM, the stack location and the BFV location.
PpiList Points to a list of one or more PPI descriptors to be installed initially by the PEI core. An empty PPI list consists of a single descriptor with the end-tag EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST. As part of its initialization phase, the PEI Foundation will add these SEC-hosted PPIs to its PPI database such that both the PEI Foundation and any modules can leverage the associated service calls and/or code in these early PPIs.

This service publishes an interface that allows PEIMs to report status codes.

ReportStatusCode() is called by PEIMs that wish to report status information on their progress. The principal use model is for a PEIM to emit one of the standard 32-bit error codes. This will allow a platform owner to ascertain the state of the system, especially under conditions where the full consoles might not have been installed.

Parameters:
PeiServices An indirect pointer to the EFI_PEI_SERVICES table published by the PEI Foundation.
Type Indicates the type of status code being reported.
Value Describes the current status of a hardware or software entity. This includes information about the class and subclass that is used to classify the entity as well as an operation. For progress codes, the operation is the current activity. For error codes, it is the exception.For debug codes,it is not defined at this time.
Instance The enumeration of a hardware or software entity within the system. A system may contain multiple entities that match a class/subclass pairing. The instance differentiates between them. An instance of 0 indicates that instance information is unavailable, not meaningful, or not relevant. Valid instance numbers start with 1.
CallerId This optional parameter may be used to identify the caller. This parameter allows the status code driver to apply different rules to different callers.
Data This optional parameter may be used to pass additional data.

[in] ResetData For a ResetType of EfiResetCold, EfiResetWarm, or EfiResetShutdown the data buffer starts with a Null-terminated string, optionally followed by additional binary data. The string is a description that the caller may use to further indicate the reason for the system reset. ResetData is only valid if ResetStatus is something other than EFI_SUCCESS unless the ResetType is EfiResetPlatformSpecific where a minimum amount of ResetData is always required.
