This patchset uses memfd to create actual files backing anonymous memory. This enabled virtio to work not only without hugetlbfs, but without hugepages altogether, which could be useful in Cloud Native scenarios. v2: - Fixed segment fd list not being initialized - Added some segment fd API fixes - Added unit test for segment fd API Anatoly Burakov (5): mem: fix error code for segment fd API for external segs memalloc: check for memfd support in segment fd API memalloc: allow setting up segment list fd's mem: use memfd for no-huge mode test: add segment fd API test doc/guides/rel_notes/release_19_02.rst | 13 +++++ lib/librte_eal/bsdapp/eal/eal_memalloc.c | 6 ++ lib/librte_eal/common/eal_common_memory.c | 12 ++++ lib/librte_eal/common/eal_memalloc.h | 4 ++ lib/librte_eal/linuxapp/eal/eal_memalloc.c | 66 +++++++++++++++++++--- lib/librte_eal/linuxapp/eal/eal_memory.c | 54 +++++++++++++++++- test/test/test_memory.c | 43 ++++++++++++++ 7 files changed, 188 insertions(+), 10 deletions(-) -- 2.17.1
