This patchset uses memfd to create actual files backing anonymous memory. This enabled virtio-user to work not only without hugetlbfs (which was already possible), but without hugepages altogether, which could be useful in Cloud Native scenarios. v3: - Clarify doc changes 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
