2 This module updates S3 Resume Performance Record in ACPI Firmware Performance\r
3 Data Table in S3 resume boot mode. In normal boot mode, this module consumes\r
4 SecPerformance PPI produced by SEC phase and build Hob to convey the SEC\r
5 performance data to DXE phase.\r
6\r
7 This module register report status code listener to collect performance data\r
8 for S3 Resume Performance Record on S3 resume boot path.\r
