[dpdk-dev] Walk through a given mbuf-pool elements

Team,

I am looking for a code/api to walk through a dpdk mbuf-pool elements (similar to rte_mempool_walk() but for elements within mempool).   Calling pkt_mbuf_alloc for 'n' elements and then _free is not an option.  Rte_mempool_obj_itr() walks through, but does lot more than walking itself.   Please suggest if anybody has better alternatives.

Thanks,
-Vithal

Not sure why rte_mempool_obj_iter() wouldn't work for you?
It just walks through all elements of the pool and for ach calls a user provided callback.
Nothing else.

Hi Konstantin,

Thanks for the reply.
I was trying to find more intuitive one compare to rte_mempool_obj_iter().  Once mempool is created with objects, shouldn't we able to walk-through by just passing 'mp' object and avoiding other params like vaddr, elt_size etc.   For now, I could use callback called during mempool creation itself.


Thanks,
