| EFI SMM Control2 Protocol as defined in the PI 1.2 specification. |
| |
| This protocol is used initiate synchronous SMI activations. This protocol could be published by a |
| processor driver to abstract the SMI IPI or a driver which abstracts the ASIC that is supporting the |
| APM port. Because of the possibility of performing SMI IPI transactions, the ability to generate this |
| event from a platform chipset agent is an optional capability for both IA-32 and x64-based systems. |
| |
| The EFI_SMM_CONTROL2_PROTOCOL is produced by a runtime driver. It provides an |
| abstraction of the platform hardware that generates an SMI. There are often I/O ports that, when |
| accessed, will generate the SMI. Also, the hardware optionally supports the periodic generation of |
| these signals. |
