Subject: [dpdk-dev] [PATCH v6 0/3] eal: add memory pre-allocation from existing files
Date: Mon, 11 Oct 2021 11:56:41 +0300	[thread overview]
Message-ID: <20211011085644.2716490-1-dkozlyuk@nvidia.com> (raw)
In-Reply-To: <20210921081632.858873-1-dkozlyuk@nvidia.com>

Hugepage allocation from the system takes time, resulting in slow
startup or sporadic delays later. Most of the time spent in kernel
is zero-filling memory for security reasons, which may be irrelevant
in a controlled environment. The bottleneck is memory access speed,
so for speeduup the amount of memory cleared must be reduced.
We propose a new EAL option --mem-file FILE1,FILE2,... to quickly
allocate dirty pages from existing files and clean it as necessary.
A new malloc_perf_autotest is provided to estimate the impact.
More details are explained in relevant patches.

v6: fix copyright line (Thomas), add SPDX header for the new test file
    (BTW, why didn't the CI complain in previous versions?)
v5: rebase
v4: getmntent() -> getmntent_r(), better error detection (John Levon)
v3: fix hugepage mount point detection
v2: fix CI failures

  eal/linux: make hugetlbfs analysis reusable
  app/test: add allocator performance autotest
