EFI MM Control PPI definition.
|
|
|
|
This PPI is used initiate synchronous MMI activations. This PPI could be published by a processor
|
|
driver to abstract the MMI IPI or a driver which abstracts the ASIC that is supporting the APM port.
|
|
Because of the possibility of performing MMI 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.
