Detailed Description

This module collects performance data for MM driver boot records and S3 Suspend Performance Record.

This module registers report status code listener to collect performance data for MM driver boot records and S3 Suspend Performance Record.

Caution: This module requires additional review when modified. This driver will have external input - communicate buffer in MM mode. This external input must be validated carefully to avoid security issue like buffer overflow, integer overflow.

FpdtSmiHandler() will receive untrusted input and do basic validation.

◆ FpdtStatusCodeListenerMm()

EFI_STATUS EFIAPI FpdtStatusCodeListenerMm	(	IN EFI_STATUS_CODE_TYPE	CodeType,
		IN EFI_STATUS_CODE_VALUE	Value,
		IN UINT32	Instance,
		IN EFI_GUID *	CallerId,
		IN EFI_STATUS_CODE_DATA *	Data
	)

Report status code listener for MM. This is used to record the performance data for S3 Suspend Start and S3 Suspend End in FPDT.

Parameters

[in]	CodeType	Indicates the type of status code being reported.
[in]	Value	Describes the current status of a hardware or software entity. This included information about the class and subclass that is used to classify the entity as well as an operation.
[in]	Instance	The enumeration of a hardware or software entity within the system. Valid instance numbers start with 1.
[in]	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.
[in]	Data	This optional parameter may be used to pass additional data.
