MdeModulePkg: Remove GetBootMode() at FirmwarePerformancePeiEntryPoint

[mirror_edk2.git] / MdeModulePkg / Universal / Acpi / FirmwarePerformanceDataTablePei / FirmwarePerformancePei.c

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