| typedef EFI_STATUS(EFIAPI * EBC_ICACHE_FLUSH) (IN EFI_PHYSICAL_ADDRESS Start, IN UINT64 Length) |
This is the prototype for the Flush callback routine. A pointer to a routine of this type is passed to the EBC EFI_EBC_REGISTER_ICACHE_FLUSH protocol service.
| Start | The beginning physical address to flush from the processor's instruction cache. |
| Length | The number of bytes to flush from the processor's instruction cache. |
| EFI_SUCCESS | The function completed successfully. |
| typedef EFI_STATUS(EFIAPI * EFI_EBC_CREATE_THUNK) (IN EFI_EBC_PROTOCOL *This, IN EFI_HANDLE ImageHandle, IN VOID *EbcEntryPoint, OUT VOID **Thunk) |
Creates a thunk for an EBC entry point, returning the address of the thunk.
A PE32+ EBC image, like any other PE32+ image, contains an optional header that specifies the entry point for image execution. However, for EBC images, this is the entry point of EBC instructions, so is not directly executable by the native processor. Therefore, when an EBC image is loaded, the loader must call this service to get a pointer to native code (thunk) that can be executed, which will invoke the interpreter to begin execution at the original EBC entry point.
| This | A pointer to the EFI_EBC_PROTOCOL instance. |
| ImageHandle | Handle of image for which the thunk is being created. |
| EbcEntryPoint | Address of the actual EBC entry point or protocol service the thunk should call. |
| Thunk | Returned pointer to a thunk created. |
| EFI_SUCCESS | The function completed successfully. |
| EFI_INVALID_PARAMETER | Image entry point is not 2-byte aligned. |
| EFI_OUT_OF_RESOURCES | Memory could not be allocated for the thunk. |
| typedef EFI_STATUS(EFIAPI * EFI_EBC_GET_VERSION) (IN EFI_EBC_PROTOCOL *This, IN OUT UINT64 *Version) |
Called to get the version of the interpreter.
This function is called to get the version of the loaded EBC interpreter. The value and format of the returned version is identical to that returned by the EBC BREAK 1 instruction.
| This | A pointer to the EFI_EBC_PROTOCOL instance. |
| Version | Pointer to where to store the returned version of the interpreter. |
| EFI_SUCCESS | The function completed successfully. |
| EFI_INVALID_PARAMETER | Version pointer is NULL. |
| typedef struct _EFI_EBC_PROTOCOL EFI_EBC_PROTOCOL |
| typedef EFI_STATUS(EFIAPI * EFI_EBC_REGISTER_ICACHE_FLUSH) (IN EFI_EBC_PROTOCOL *This, IN EBC_ICACHE_FLUSH Flush) |
Registers a callback function that the EBC interpreter calls to flush the processor instruction cache following creation of thunks.
| This | A pointer to the EFI_EBC_PROTOCOL instance. |
| Flush | Pointer to a function of type EBC_ICACH_FLUSH. |
| EFI_SUCCESS | The function completed successfully. |
| typedef EFI_STATUS(EFIAPI * EFI_EBC_UNLOAD_IMAGE) (IN EFI_EBC_PROTOCOL *This, IN EFI_HANDLE ImageHandle) |
Called prior to unloading an EBC image from memory.
This function is called after an EBC image has exited, but before the image is actually unloaded. It is intended to provide the interpreter with the opportunity to perform any cleanup that may be necessary as a result of loading and executing the image.
| This | A pointer to the EFI_EBC_PROTOCOL instance. |
| ImageHandle | Image handle of the EBC image that is being unloaded from memory. |
| EFI_SUCCESS | The function completed successfully. |
| EFI_INVALID_PARAMETER | Image handle is not recognized as belonging to an EBC image that has been executed. |
