Field Documentation

◆ 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 1258 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.

Definition at line 1264 of file Acpi50.h.

◆ Header

EFI_ACPI_5_0_FPDT_PERFORMANCE_RECORD_HEADER EFI_ACPI_5_0_FPDT_FIRMWARE_BASIC_BOOT_RECORD::Header

Definition at line 1235 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 1246 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.
