Function Details

ocs_hal_rtn_e ocs_hal_callback	(	ocs_hal_t *	hal,
		ocs_hal_callback_e	which,
		void *	func,
		void *	arg
	)

Register a callback for the given event.

Parameters

hal	Hardware context.
which	Event of interest.
func	Function to call when the event occurs.
arg	Argument passed to the callback function.

Returns: Returns 0 on success, or a non-zero value on failure.

Definition at line 2824 of file ocs_hal.c.

ocs_hal_rtn_e ocs_hal_init ( ocs_hal_t * hal )

Allocate memory structures to prepare for the device operation.

Description: Allocates memory structures needed by the device and prepares the device for operation.

Note: This function may be called more than once (for example, at initialization and then after a reset), but the size of the internal resources may not be changed without tearing down the HAL (ocs_hal_teardown()).

Parameters

hal	Hardware context allocated by the caller.

Returns: Returns 0 on success, or a non-zero value on failure.

Definition at line 813 of file ocs_hal.c.

static ocs_hal_rtn_e ocs_hal_read_max_dump_size ( ocs_hal_t * hal )

static

Read the max dump size for this port.

Description: Queries the FW for the maximum dump size

Parameters

hal	Hardware context allocated by the caller.

Returns: Returns 0 on success, or a non-zero value on failure.

Definition at line 420 of file ocs_hal.c.

ocs_hal_rtn_e ocs_hal_rqpair_init ( ocs_hal_t * hal )

Configure the rq_pair function from ocs_hal_init(). Must be after the IOs are setup and the state is active.

Description: Allocates the TOW buffers and posts initial XRIs for this feature.

Parameters

hal	Hardware context allocated by the caller.

Returns: Returns 0 on success, or a non-zero value on failure.

Definition at line 918 of file ocs_hal_rqpair.c.

void ocs_hal_rqpair_teardown ( ocs_hal_t * hal )

Tear down the rq_pair function from ocs_hal_teardown().

Description: Frees the buffers to TOW buffers.

Parameters

hal	Hardware context allocated by the caller.

Definition at line 967 of file ocs_hal_rqpair.c.

ocs_hal_rtn_e ocs_hal_rqpair_tow_buffer_alloc	(	ocs_hal_t *	hal,
		uint32_t	num_buffers
	)

Allocate tow buffers.

Description: Allocates the tow buffers and places them on the free list.

Parameters

hal	Hardware context allocated by the caller.
num_buffers	Number of buffers to allocate.

Returns: Returns 0 on success, or a non-zero value on failure.

Definition at line 587 of file ocs_hal_rqpair.c.

static void ocs_hal_rqpair_tow_buffer_free ( ocs_hal_t * hal )

static

Free tow buffers.

Description: Frees the tow buffers.

Parameters

hal	Hardware context allocated by the caller.

Returns: Returns 0 on success, or a non-zero value on failure.

Definition at line 886 of file ocs_hal_rqpair.c.

static void ocs_hal_rqpair_tow_dnrx_check ( ocs_hal_t * hal )

static

Post Auto xfer rdy buffers to the XRIs posted with DNRX.

Description: When new buffers are freed, check existing XRIs waiting for buffers.

Parameters

hal	Hardware context allocated by the caller.

Definition at line 644 of file ocs_hal_rqpair.c.

ocs_hal_rtn_e ocs_hal_setup	(	ocs_hal_t *	hal,
		ocs_os_handle_t	os,
		sli4_port_type_e	port_type
	)

Set up the Hardware Abstraction Layer module.

Description: Calls set up to configure the hardware.

Parameters

hal	Hardware context allocated by the caller.
os	Device abstraction.
port_type	Protocol type of port, such as FC and NIC.

Returns: Returns 0 on success, or a non-zero value on failure.

Definition at line 606 of file ocs_hal.c.

ocs_hal_rtn_e ocs_hal_teardown ( ocs_hal_t * hal )

Tear down the Hardware Abstraction Layer module.

Description: Frees memory structures needed by the device, and shuts down the device. Does not free the HAL context memory (which is done by the caller).

Parameters

hal	Hardware context allocated by the caller.

Returns: Returns 0 on success, or a non-zero value on failure.
