EFI SMM Control PPI definition.
|
|
|
|
This PPI is used to initiate SMI/PMI activations. This protocol could be published by either:
|
|
- A processor driver to abstract the SMI/PMI IPI
|
|
- The driver that abstracts the ASIC that is supporting the APM port, such as the ICH in an
|
|
Intel chipset
|
|
Because of the possibility of performing SMI or PMI IPI transactions, the ability to generate this
|
|
event from a platform chipset agent is an optional capability for both IA-32 and Itanium-based
|
|
systems.
