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.
