Hi All,



Like =E2=80=98rte_eal_get_physmem_size=E2=80=99 api to the total size of th=
e physical
memory. Is there an API to get to get total free memory physical memory
available ?



We want such API we are planning to implement such API for the same



/* get the total size of memory */

uint64_t

rte_eal_get_physmem_free(int socket_id)

{

const struct rte_mem_config *mcfg;

unsigned i =3D 0;

uint64_t total_len =3D 0;



/* get pointer to global configuration */

mcfg =3D rte_eal_get_configuration()->mem_config;



for (i=3D0; i<RTE_MAX_MEMSEG; i++) {

if (mcfg->free_memseg[i].addr =3D=3D NULL)

break;



if (mcfg->free_memseg[i].len =3D=3D 0)

continue;



/* bad socket ID */

if (socket_id !=3D SOCKET_ID_ANY &&

mcfg->free_memseg[i].socket_id !=3D SOCKET_ID_ANY &&

socket_id !=3D mcfg->free_memseg[i].socket_id)

continue;



total_len +=3D mcfg->free_memseg[i].len;

}



return total_len;

}



Thanks,

Regards
