Function Details

void hal_thread_cq_handler	(	ocs_hal_t *	hal,
		hal_cq_t *	cq
	)

void hal_thread_eq_handler	(	ocs_hal_t *	hal,
		hal_eq_t *	eq,
		uint32_t	max_isr_time_msec
	)

ocs_hal_rtn_e ocs_hal_init_queues	(	ocs_hal_t *	hal,
		ocs_hal_qtop_t *	qtop
	)

Initialize queues.

Given the parsed queue topology spec, the SLI queues are created and initialized

Parameters

hal	pointer to HAL object
qtop	pointer to queue topology

Returns: returns 0 for success, an error code value for failure.

Definition at line 56 of file ocs_hal_queues.c.

const char* ocs_hal_qtop_entry_name ( ocs_hal_qtop_entry_e entry )

uint32_t ocs_hal_qtop_eq_count ( ocs_hal_t * hal )

Return count of EQs for a queue topology object.

The EQ count for in the HALs queue topology (hal->qtop) object is returned

Parameters

hal	pointer to HAL object

Returns: count of EQs

Definition at line 1097 of file ocs_hal_queues.c.

void ocs_hal_qtop_free ( ocs_hal_qtop_t * qtop )

free queue topology object

Parameters

qtop	pointer to QTOP object

Returns: none

Definition at line 1765 of file ocs_hal_queues.c.

ocs_hal_qtop_t* ocs_hal_qtop_parse	(	ocs_hal_t *	hal,
		const char *	qtop_string
	)

Parse queue topology string.

The queue topology object is allocated, and filled with the results of parsing the passed in queue topology string

Parameters

hal	pointer to HAL object
qtop_string	input queue topology string

Returns: pointer to allocated QTOP object, or NULL if there was an error

Definition at line 1687 of file ocs_hal_queues.c.

hal_wq_t* ocs_hal_queue_next_wq	(	ocs_hal_t *	hal,
		ocs_hal_io_t *	io
	)

Allocate a WQ to an IO object.

The next work queue index is used to assign a WQ to an IO.

If wq_steering is OCS_HAL_WQ_STEERING_CLASS, a WQ from io->wq_class is selected.

If wq_steering is OCS_HAL_WQ_STEERING_REQUEST, then a WQ from the EQ that the IO request came in on is selected.

If wq_steering is OCS_HAL_WQ_STEERING_CPU, then a WQ associted with the CPU the request is made on is selected.

Parameters

hal	pointer to HAL object
io	pointer to IO object

Returns: Return pointer to next WQ
