Function Details

int32_t dif_pool_alloc	(	ocs_t *	ocs,
		ocs_list_t *	head,
		uint32_t	size,
		ocs_difdma_t *	difdma
	)

Allocate memory for the DIF memory pool.

Description: Allocates a buffer of size from a DIF memory pool. Returns a physical address.

Parameters

ocs	Pointer to the ocs_t structure.
head	Pointer to the head of a DIF pool entry linked list.
size	Size of the memory to allocate.
difdma	Returns the address of the requested DIF segment.

Returns: Returns 0 on success.

Definition at line 724 of file ocs_ramdisc.c.

void dif_pool_free	(	ocs_t *	ocs,
		ocs_list_t *	head
	)

Free the DIF memory pool.

Description: Frees all of the DIF memory pool buffers.

Parameters

ocs	Pointer to the ocs structure.
head	Pointer to the head of DIF pool entries list.

Returns: None.

Definition at line 660 of file ocs_ramdisc.c.

void dif_pool_init	(	ocs_t *	ocs,
		ocs_list_t *	head
	)

initialize the DIF memory pool

Description: Clears all previous allocations of DIF memory. Leaves all the previously-allocated memory buffers in the pool.

Parameters

ocs	Pointer to the ocs structure.
head	Head of the dif_pool_t linked list.

Returns: None.

Definition at line 636 of file ocs_ramdisc.c.

static int32_t dif_pool_new	(	ocs_t *	ocs,
		ocs_list_t *	head
	)

static

Allocate a new dif_pool_t entry.

Description: Allocates a new dif_pool_t entry.

Parameters

ocs	Pointer to the ocs_t structure.
head	Pointer to the head of DIF buffer entry linked list.

Returns: Returns 0 on success, a negative error code value on failure.
