Select this option, if you want to enable support for IO Event
|
|
|
|
interrupts. IO event interrupt is a mechanism provided by RTAS
|
|
|
|
to return information about hardware error and non-error events
|
|
|
|
which may need OS attention. RTAS returns events for multiple
|
|
|
|
event types and scopes. Device drivers can register their handlers
|
|
|
|
to receive events.
|
|
|
|
|

This option will only enable the IO event platform code. You

will still need to enable or compile the actual drivers

Select this option, if you want to enable the kernel interface
