Field Documentation

Header

EFI_ACPI_5_0_FPDT_PERFORMANCE_RECORD_HEADER EFI_ACPI_5_0_FPDT_FIRMWARE_BASIC_BOOT_RECORD::Header

Definition at line 1203 of file Acpi50.h.

Reserved

UINT32 EFI_ACPI_5_0_FPDT_FIRMWARE_BASIC_BOOT_RECORD::Reserved

Definition at line 1204 of file Acpi50.h.

ResetEnd

UINT64 EFI_ACPI_5_0_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.

Definition at line 1209 of file Acpi50.h.

OsLoaderLoadImageStart

UINT64 EFI_ACPI_5_0_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.

Definition at line 1214 of file Acpi50.h.

OsLoaderStartImageStart

UINT64 EFI_ACPI_5_0_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.

Definition at line 1220 of file Acpi50.h.

ExitBootServicesEntry

UINT64 EFI_ACPI_5_0_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.

Definition at line 1226 of file Acpi50.h.

ExitBootServicesExit

UINT64 EFI_ACPI_5_0_FPDT_FIRMWARE_BASIC_BOOT_RECORD::ExitBootServicesExit

Timer value logged at the point just prior to when 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.
