This will allow DPDK to reserve hugepages\nanonymously instead of using hugetlbfs mountpoints. Coupled\nwith the fact that this option also effectively enables both\n\"--no-shconf\" and \"--huge-unlink\" modes, DPDK will be able\nto run entirely in memory and not create any shared files\nwhile running - neither hugepages nor any runtime data.\n\nThis will, of course, disable secondary processes, but for\nuse-cases this is targeted at (containers etc.), this is\nnot a problem.\n\nOlder revisions had kernel support at 4.14+ and also\nrequired a fairly new glibc, but now due to not using memfd\nand using mmap() instead, minimum supported kernel version\nhas dropped to 3.8.\n\nv1->v2 changes:\n- Rebase on latest master\n- Fix patch 5 to include check from patch 6 as commit message\n states\n\nRFC->v1 changes:\n- Dropped memfd, using anonymous mmap() instead\n- Do not deprecate old command-line parameters, instead\n use them as they are, and add a deprecation notice to\n remove them in the next release.\n\nAnatoly Burakov (9):\n fbarray: support no-shconf mode\n ipc: add support for no-shconf mode\n eal: add support for no-shconf for hugepage info\n eal: add support for no-shconf in hugepage data file\n eal: do not create runtime dir in no-shconf mode\n mem: add support for hugepage-unlink mode\n eal: add --in-memory option\n doc: add deprecation notice for EAL command line options\n mem: support in-memory mode\n\n doc/guides/rel_notes/deprecation.rst | 5 +\n lib/librte_eal/bsdapp/eal/eal.c | 3 +-\n lib/librte_eal/bsdapp/eal/eal_hugepage_info.c | 4 +\n lib/librte_eal/common/eal_common_fbarray.c | 71 +++++----\n lib/librte_eal/common/eal_common_options.c | 20 ++-\n lib/librte_eal/common/eal_common_proc.c | 25 ++++\n lib/librte_eal/common/eal_internal_cfg.h | 4 +\n lib/librte_eal/common/eal_options.h | 2 +\n lib/librte_eal/linuxapp/eal/eal.c | 3 +-\n .../linuxapp/eal/eal_hugepage_info.c | 95 ++++++++----\n lib/librte_eal/linuxapp/eal/eal_memalloc.c | 140 ++++++++++++------\n lib/librte_eal/linuxapp/eal/eal_memory.c | 16 +-\n 12 files changed, 271 insertions(+), 117 deletions(-)" }
