Looking at eal_init/eal_hugepage_info_init it seems that DPDK will try to grab All available huge pages. Is there an existing way to limit the number of huge pages taken ? My goal is to be able to run several applications each with its own dpdk instance and a possible 3rd party application all using huge pages. Is this possible under DPDKs current design? Sharing the NICs is fairly simple if we specify the available lci functions per dpdk instance but at first glance sharing huge pages looks like a problem. Thanks.
