isci_host_completion_routine() - This function is the delayed service routine that calls the sci core library's completion handler. It's scheduled as a tasklet from the interrupt service routine when interrupts in use, or set as the timeout function in polled mode. : This parameter specifies the ISCI host object
isci_host_deinit - shutdown frame reception and dma : host to take down
This is called in either the driver shutdown or the suspend path. In the shutdown case libsas went through port teardown and normal device removal (i.e. physical links stayed up to service scsi_device removal commands). In the suspend case we disable the hardware without notifying libsas of the link down events since we want libsas to remember the domain across the suspend/resume cycle
isci_host_init - (re-)initialize hardware and internal (private) state : host to init
Any public facing objects (like asd_sas_port, and asd_sas_phys), or one-time initialization objects like locks and waitqueues, are not touched (they are initialized in isci_host_alloc)

This method allocates remote node index and the reserves the remote node context space for use. This method can fail if there are no more remote node index available. : This is the controller object which contains the set of free remote node ids : This is the device object which is requesting the a remote node id : This is the remote node id that is assinged to the device if one is available

sci_controller_complete_io() - This method will perform core specific completion operations for an IO request. After this method is invoked, the user should consider the IO request as invalid until it is properly reused (i.e. re-constructed). : The handle to the controller object for which to complete the IO request. : The handle to the remote device object for which to complete the IO request. : the handle to the io request object to complete.

sci_controller_start_task() - This method is called by the SCIC user to send/start a framework task management request. : the handle to the controller object for which to start the task management request. : the handle to the remote device object for which to start the task management request. : the handle to the task request object to start.
