Enumeration Type Documentation
Enumeration of memory types introduced in UEFI.
- Enumerator:
-
EfiReservedMemoryType |
Not used. |
EfiLoaderCode |
The code portions of a loaded application. (Note that UEFI OS loaders are UEFI applications.) |
EfiLoaderData |
The data portions of a loaded application and the default data allocation type used by an application to allocate pool memory. |
EfiBootServicesCode |
The code portions of a loaded Boot Services Driver. |
EfiBootServicesData |
The data portions of a loaded Boot Serves Driver, and the default data allocation type used by a Boot Services Driver to allocate pool memory. |
EfiRuntimeServicesCode |
The code portions of a loaded Runtime Services Driver. |
EfiRuntimeServicesData |
The data portions of a loaded Runtime Services Driver and the default data allocation type used by a Runtime Services Driver to allocate pool memory. |
EfiConventionalMemory |
Free (unallocated) memory. |
EfiUnusableMemory |
Memory in which errors have been detected. |
EfiACPIReclaimMemory |
Memory that holds the ACPI tables. |
EfiACPIMemoryNVS |
Address space reserved for use by the firmware. |
EfiMemoryMappedIO |
Used by system firmware to request that a memory-mapped IO region be mapped by the OS to a virtual address so it can be accessed by EFI runtime services. |
EfiMemoryMappedIOPortSpace |
System memory-mapped IO region that is used to translate memory cycles to IO cycles by the processor. |
EfiPalCode |
Address space reserved by the firmware for code that is part of the processor. |
EfiPersistentMemory |
A memory region that operates as EfiConventionalMemory, however it happens to also support byte-addressable non-volatility. |
EfiMaxMemoryType |
|
Enumeration of reset types.
- Enumerator:
-
EfiResetCold |
Used to induce a system-wide reset. This sets all circuitry within the system to its initial state. This type of reset is asynchronous to system operation and operates withgout regard to cycle boundaries. EfiColdReset is tantamount to a system power cycle. |
EfiResetWarm |
Used to induce a system-wide initialization. The processors are set to their initial state, and pending cycles are not corrupted. If the system does not support this reset type, then an EfiResetCold must be performed. |
EfiResetShutdown |
Used to induce an entry into a power state equivalent to the ACPI G2/S5 or G3 state. If the system does not support this reset type, then when the system is rebooted, it should exhibit the EfiResetCold attributes. |
EfiResetPlatformSpecific |
Used to induce a system-wide reset. The exact type of the reset is defined by the EFI_GUID that follows the Null-terminated Unicode string passed into ResetData. If the platform does not recognize the EFI_GUID in ResetData the platform must pick a supported reset type to perform. The platform may optionally log the parameters from any non-normal reset that occurs. |
