REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2957 1. Allocate performance data table at EndOfDxe and then lock the varible which store the table address at EndOfDxe. 2. Enlarge PCD gEfiMdeModulePkgTokenSpaceGuid.PcdExtFpdtBootRecordPadSize from 0x20000 to 0x30000 in order to hold the Delta performance data between EndOfDxe and ReadyToBoot. 3. SMM performance data is collected by DXE modules through SMM communication at ReadyToBoot before. Now to do SMM communication twice, one for allocating the performance size at EndOfDxe, another is at ReadyToBoot to get SMM performance data. 4. Make SmmCorePerformanceLib rather than FirmwarePerformanceSmm to communicate with DxeCorePerformanceLib for SMM performance data and size.

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