#define AIF_SNIFF_TIMEOUT   (30*HZ)

aac_handle_aif - Handle a message from the firmware : Which adapter this fib is from : Pointer to fibptr from adapter

This routine handles a driver notify fib from the adapter and dispatches it to the appropriate routine for handling.

(

void *

data

)

aac_command_thread - command processing thread : Adapter to monitor

Waits on the commandready event in it's queue. When the event gets set it will pull FIBs off it's queue. It will continue to pull FIBs off until the queue is empty. When the queue is empty it will wait for more FIBs.

void aac_consumer_free	(	struct aac_dev *	dev,
		struct aac_queue *	q,
		u32	qid
	)

aac_consumer_free - free consumer entry : Adapter : Queue : Queue ident

Frees up the current top of the queue we are a consumer of. If the queue was full notify the producer that the queue is no longer full.

Definition at line 666 of file commsup.c.

int aac_consumer_get	(	struct aac_dev *	dev,
		struct aac_queue *	q,
		struct aac_entry **	entry
	)

aac_consumer_get - get the top of the queue : Adapter : Queue : Return entry

Will return a pointer to the entry on the top of the queue requested that we are a consumer of, and return the address of the queue entry. It does not change the state of the queue.

Definition at line 634 of file commsup.c.

int aac_fib_adapter_complete	(	struct fib *	fibptr,
		unsigned short	size
	)

aac_fib_adapter_complete - complete adapter issued fib : fib to complete : size of fib

Will do all necessary work to complete a FIB that was sent from the adapter.

Definition at line 705 of file commsup.c.

struct fib* aac_fib_alloc ( struct aac_dev *  dev )

read

aac_fib_alloc - allocate a fib : Adapter to allocate the fib for

Allocate a fib from the adapter fib pool. If the pool is empty we return NULL.

Definition at line 173 of file commsup.c.

int aac_fib_complete

(

struct fib *

fibptr

)

aac_fib_complete - fib completion handler : FIB to complete

Will do all necessary work to complete a FIB.

Definition at line 776 of file commsup.c.

void aac_fib_free

(

struct fib *

fibptr

)

aac_fib_free - free a fib : fib to free up

Frees up a fib and places it on the appropriate queue

Definition at line 209 of file commsup.c.

void aac_fib_init

(

struct fib *

fibptr

)

aac_fib_init - initialise a fib : The fib to initialize

Set up the generic fib fields ready for use

Definition at line 240 of file commsup.c.

void aac_fib_map_free

(

struct aac_dev *

dev

)

aac_fib_map_free - free the fib objects : Adapter to free

Free the PCI mappings and the memory allocated for FIB blocks on this adapter.

Definition at line 84 of file commsup.c.

int aac_fib_send	(	u16	command,
		struct fib *	fibptr,
		unsigned long	size,
		int	priority,
		int	wait,
		int	reply,
		fib_callback	callback,
		void *	callback_data
	)

aac_fib_send - send a fib to the adapter : Command to send : The fib : Size of fib data area : Priority of Fib : Async/sync select : True if a reply is wanted : Called with reply : Passed to callback

Sends the requested FIB to the adapter and optionally will wait for a response FIB. If the caller does not wish to wait for a response than an event to wait on must be supplied. This event will be set when a response FIB is received from the adapter.

Definition at line 410 of file commsup.c.

int aac_fib_setup

(

struct aac_dev *

dev

)

aac_fib_setup - setup the fibs : Adapter to set up

Allocate the PCI space for the fibs, map it and then initialise the fib area, the unmapped fib data and also the free list

Definition at line 101 of file commsup.c.

void aac_printf	(	struct aac_dev *	dev,
		u32	val
	)

aac_printf - handle printf from firmware : Adapter : Message info

Print a message passed to us by the controller firmware on the Adaptec board

Definition at line 837 of file commsup.c.

		u32 *	index,
		u32	qid,
		struct hw_fib *	hw_fib,
		int	wait,
		struct fib *	fibptr,
		unsigned long *	nonotify
	)

aac_queue_get - get the next free QE : Adapter : Returned index : Priority of fib : Fib to associate with the queue entry : Wait if queue full : Driver fib object to go with fib : Don't notify the adapter

Gets the next free QE off the requested priorty adapter command queue and associates the Fib with the QE. The QE represented by index is ready to insert on the queue when this routine returns success.
