| help |
| 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 infrastruture to handle IO event interrupts. |
