Subject: [dpdk-dev] [RFC 01/10] eal: add --no-shared-files option
Date: Thu, 31 May 2018 15:32:24 +0100 [thread overview]
Message-ID: <a5a8f937e3e74d892a884189d2c245556e42eb8c.1527776837.git.anatoly.burakov@intel.com> (raw)
In-Reply-To: <cover.1527776837.git.anatoly.burakov@intel.com>
In-Reply-To: <cover.1527776837.git.anatoly.burakov@intel.com>
This command-line option will cause DPDK to not create any shared
files at runtime, including any shared configuration or hugetlbfs
files. This is useful for debug purposes, as well as for certain
use cases like containers.
Currently, this option does nothing.
