[edk2] [patch 6/8] MdeModulePkg/FirmwarePerfDxe:Enhance for new pref infrastructure
Posted by Dandan Bi 6 years, 9 months ago
1. Remove the macro EXTENSION_RECORD_SIZE, since the extension
size can be got through PcdExtFpdtBootRecordPadSize.
2. Hook EFI_SW_DXE_BS_PC_READY_TO_BOOT_EVENT to install ACPI table
3. Copy SMM record according to the allocated size
