This will allow DPDK to reserve hugepages anonymously instead of using hugetlbfs mountpoints. Coupled with the fact that this option also effectively enables both "--no-shconf" and "--huge-unlink" modes, DPDK will be able to run entirely in memory and not create any shared files while running - neither hugepages nor any runtime data. This will, of course, disable secondary processes, but for use-cases this is targeted at (containers etc.), this is not a problem. Older revisions had kernel support at 4.14+ and also required a fairly new glibc, but now due to not using memfd and using mmap() instead, minimum supported kernel version has dropped to 3.8. v2->v3 changes: - Fix compile issue in patch 9 (now 8) - Drop deprecation notice (will be sent separately) v1->v2 changes: - Rebase on latest master - Fix patch 5 to include check from patch 6 as commit message states RFC->v1 changes: - Dropped memfd, using anonymous mmap() instead - Do not deprecate old command-line parameters, instead use them as they are, and add a deprecation notice to remove them in the next release.
