Field Documentation

UINT64 EFI_ACPI_6_3_FPDT_FIRMWARE_BASIC_BOOT_RECORD::ExitBootServicesEntry

Timer value logged at the point when the OS loader calls the ExitBootServices function for UEFI compatible firmware. For non-UEFI compatible boots, this field must be zero.

UINT64 EFI_ACPI_6_3_FPDT_FIRMWARE_BASIC_BOOT_RECORD::ExitBootServicesExit

Timer value logged at the point just prior towhen the OS loader gaining control back from calls the ExitBootServices function for UEFI compatible firmware. For non-UEFI compatible boots, this field must be zero.

EFI_ACPI_6_3_FPDT_PERFORMANCE_RECORD_HEADER EFI_ACPI_6_3_FPDT_FIRMWARE_BASIC_BOOT_RECORD::Header

UINT64 EFI_ACPI_6_3_FPDT_FIRMWARE_BASIC_BOOT_RECORD::OsLoaderLoadImageStart

Timer value logged just prior to loading the OS boot loader into memory. For non-UEFI compatible boots, this field must be zero.

UINT64 EFI_ACPI_6_3_FPDT_FIRMWARE_BASIC_BOOT_RECORD::OsLoaderStartImageStart

Timer value logged just prior to launching the previously loaded OS boot loader image. For non-UEFI compatible boots, the timer value logged will be just prior to the INT 19h handler invocation.

UINT32 EFI_ACPI_6_3_FPDT_FIRMWARE_BASIC_BOOT_RECORD::Reserved

UINT64 EFI_ACPI_6_3_FPDT_FIRMWARE_BASIC_BOOT_RECORD::ResetEnd

Timer value logged at the beginning of firmware image execution. This may not always be zero or near zero.
