This change added support of FPDT driver under StandaloneMm. It replaces SMM version ReportStatusCode protocol with MM version. This patch also abstracts standalone and traditional MM interfaces into separate files to support each corresponding function prototypes and implementations.

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.
