└─>IO Event Interrupt support
In linux kernel since version 3 (release Date: 2011-07-21)
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
that use this infrastructure to handle IO event interrupts.
Say Y if you are unsure.
