           Summary: DPDK requires more than twice as much memory as
                    requested
           Product: DPDK
           Version: 18.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

         Component: core
          Assignee: dev at dpdk.org
          Reporter: maaaah at mail.ru
  Target Milestone: ---

I am trying to allocate 32Gb memory via rte_calloc applying config changes
advised in https://bugs.dpdk.org/show_bug.cgi?id=608. I am using 1Gb hugepages.
However, in order to success, the system requires to reserve 66 pages which is
too much - we just don't have enough RAM on our production hosts.

Please advise.
