Table 23 EDK II Module Types

MODULE_TYPE
Supported Architecture Types
Description
BASE
Any
Modules or Libraries can be ported to any execution environment. This module type is intended to be used by silicon module developers to produce source code that is not tied to any specific execution environment.
SEC
Any
Modules of this type are designed to start execution at the reset vector of a CPU. They are responsible for preparing the platform for the PEI phase.
PEI_CORE
Any
This module type is used by PEI Core implementations that are compliant with the PI Specification.
PEIM
Any
This module type is used by PEIMs that are compliant with the PI specification.
DXE_CORE
Any
This module type is used by DXE Core implementations that are compliant with the PI Specification.
DXE_DRIVER
Any
This module type is used by DXE Drivers that are compliant with the PI Specification.
DXE_RUNTIME_DRIVER
Any
This module type is used by DXE Drivers that are compliant to the PI Specification. These modules execute in both boot services and runtime services environments.
DXE_SAL_DRIVER
IPF
This module type is used by DXE Drivers that can be called in physical mode before SetVirtualAddressMap() is called and either physical mode or virtual mode after SetVirtualAddressMap() has been called. This module type is only available for IPF processor types.
DXE_SMM_DRIVER
IA32, X64
This module type is used by DXE Drivers that are loaded into SMRAM.
SMM_CORE
Any
This is the SMM core.
UEFI_DRIVER
Any
This module type is used by UEFI Drivers that are compliant with the EFI 1.10 and UEFI specifications. These modules provide services in the boot services execution environment. UEFI Drivers that return EFI_SUCCESS are not unloaded from memory. UEFI Drivers that return an error are unloaded from memory.
UEFI_APPLICATION
Any
This module type is used by UEFI Applications that are compliant with the EFI 1.10 and EFI 2.0 specifications. UEFI Applications are always unloaded when they exit.
