+  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.
