Subject: [dpdk-dev] [PATCH 19.02 0/2] Allow using virtio without hugepages
Date: Tue, 13 Nov 2018 17:54:46 +0000	[thread overview]
Message-ID: <cover.1542130721.git.anatoly.burakov@intel.com> (raw)

It is already possible to use both DPDK in general and
virtio specifically, without hugetlbfs mounts, but
currently virtio cannot be used without hugepage memory
(i.e. with a --no-huge EAL switch) due to the fact that
it needs to share memory with the backend.

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.

Anatoly Burakov (2):
  memalloc: allow setting up segment list fd's
  mem: use memfd for no-huge mode
