MdePkg/IndustryStandard: add definitions for ACPI 6.0 IORT

[mirror_edk2.git] / MdeModulePkg / Universal / Acpi / FirmwarePerformanceDataTableDxe / FirmwarePerformanceDxe.c

/** @file\r
  This module install ACPI Firmware Performance Data Table (FPDT).\r
\r
  This module register report status code listener to collect performance data\r
  for Firmware Basic Boot Performance Record and other boot performance records, \r
  and install FPDT to ACPI table.\r
