Re: Asynchronous events at the target

["Sumit Agarwal" <sumit.agarwal@wipro.com>]

AFAIK, there are various ways to dispatch an asynchronous events. They 
can be considered as interrupts. The interrupts can be issued either 
through signals or sending some know packet format for intialization.
1) Signals  - used mostly for directly attached devices
2) Transport Specific routines - fore.g RSCN in FC, A configured RPC 
may be invoked, Hello message can be sent e.t.c

Someone please correct me, if I am wrong.

Thanks,
Sumit
