Field Documentation

Name of mempool.

Examples:
examples/ioat/ioatfwd.c.

Definition at line 224 of file rte_mempool.h.

void* pool_data

Ring or pool to store objects.

Definition at line 227 of file rte_mempool.h.

uint64_t pool_id

External mempool identifier.

void* pool_config

optional args for ops alloc.

Definition at line 230 of file rte_mempool.h.

const struct rte_memzone* mz

Memzone where pool is alloc'd.

Examples:
examples/ntb/ntb_fwd.c.

Definition at line 231 of file rte_mempool.h.

unsigned int flags

Flags of the mempool.

Examples:
examples/multi_process/simple_mp/main.c.

Definition at line 232 of file rte_mempool.h.

int socket_id

Socket id passed at create.

Examples:
examples/distributor/main.c, examples/flow_classify/flow_classify.c, and examples/ntb/ntb_fwd.c.

Definition at line 233 of file rte_mempool.h.

uint32_t size

Max size of the mempool.

Examples:
examples/ip_pipeline/parser.c.

Definition at line 234 of file rte_mempool.h.

uint32_t cache_size

Size of per-lcore default local cache.

Definition at line 235 of file rte_mempool.h.

uint32_t elt_size

Size of an element.

Examples:
examples/ntb/ntb_fwd.c.

Definition at line 238 of file rte_mempool.h.

uint32_t header_size

int32_t ops_index

Index into rte_mempool_ops_table array of mempool ops structs, which contain callback function pointers. We're using an index here rather than pointers to the callbacks to facilitate any secondary processes that may want to use this mempool.

List of objects in pool

Definition at line 255 of file rte_mempool.h.

uint32_t nb_mem_chunks

Number of memory chunks

Definition at line 256 of file rte_mempool.h.

struct rte_mempool_memhdr_list mem_list

List of memory chunks

Definition at line 257 of file rte_mempool.h.
