Memzone where pool is alloc'd.

Examples:
examples/ntb/ntb_fwd.c.

Definition at line 220 of file rte_mempool.h.

◆ flags

unsigned int flags

Flags of the mempool.

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

◆ socket_id

int socket_id

◆ size

uint32_t size

Max size of the mempool.

Definition at line 223 of file rte_mempool.h.

◆ cache_size

uint32_t cache_size

Size of per-lcore default local cache.

Definition at line 224 of file rte_mempool.h.

◆ elt_size

uint32_t elt_size

Size of an element.

Examples:
examples/ntb/ntb_fwd.c.

Definition at line 227 of file rte_mempool.h.

◆ header_size

uint32_t header_size

◆ ops_index

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.

Definition at line 245 of file rte_mempool.h.

◆ mem_list

struct rte_mempool_memhdr_list mem_list

List of memory chunks

Definition at line 246 of file rte_mempool.h.
