Description

This API uses cluster delegation to FC to allocate memory in L2.

Typedef Documentation

typedef struct pi_cl_alloc_req_s pi_cl_alloc_req_t

This structure is used by the runtime to manage a cluster remote allocation. It must be instantiated once for each allocation and must be kept alive until the allocation is finished. It can be instantiated as a normal variable, for example as a global variable, a local one on the stack, or through a memory allocator.

typedef struct pi_cl_free_req_s pi_cl_free_req_t

This structure is used by the runtime to manage a cluster remote free. It must be instantiated once for each free and must be kept alive until the free is finished. It can be instantiated as a normal variable, for example as a global variable, a local one on the stack, or through a memory allocator.

Function Documentation

void pi_cl_l2_free	(	void *	chunk,
		int	size,
		pi_cl_free_req_t *	req
	)

Parameters

chunk	Chunk to be freed.
size	Size in bytes of the memory to be freed.
req	Request structure used for termination.

static void pi_cl_l2_free_wait ( pi_cl_free_req_t *  req )

inlinestatic

This blocks the calling core until the specified cluster remote free is finished.

Parameters

req	Request structure used for termination.

void pi_cl_l2_malloc	(	int	size,
		pi_cl_alloc_req_t *	req
	)

Parameters

size	Size in bytes of the memory to be allocated.
req	Request structure used for termination.

static void* pi_cl_l2_malloc_wait ( pi_cl_alloc_req_t *  req )

inlinestatic

This blocks the calling core until the specified cluster remote allocation is finished.

Parameters

req	Request structure used for termination.

Returns

Allocated chunk or NULL if there was not enough memory available.
