Subject: [dpdk-dev] [PATCH 0/9] Support running DPDK without hugetlbfs mountpoint
Date: Fri,  1 Jun 2018 18:15:09 +0100	[thread overview]
Message-ID: <cover.1527872626.git.anatoly.burakov@intel.com> (raw)

This patchset adds a new command-line option "--in-memory",
which takes old debug options "--huge-unlink" and
"--no-shconf", and enhances them with additional
functionality. 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.

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.
