However, because different platforms\nsupport different subsets of available EAL parameters, instead of\ncreating a single file, we will create a common file in\ndoc/guides/common containing documentation for EAL parameters\nthat are supported on all of our supported platforms (Linux and\nFreeBSD at the time of this writing).\n\nWe will then include this document in the Getting Started guides\nfor all supported platforms, so that any changes made to\ndocumentation for commonly supported EAL parameters will be\nreflected in Getting Started guides for all platforms.\n\nThis patch also removes EAL parameters documentation from the\ntestpmd user guide, and instead adds references to the newly\ncreated documents in both testpmd user guides and in sample\napplications guide.\n\nSigned-off-by: Anatoly Burakov <anatoly.burakov@intel.com>\nAcked-by: Ferruh Yigit <ferruh.yigit@intel.com>\nReviewed-by: Rami Rosen <roszenrami@gmail.com>\n---\n\nNotes:\n v2:\n - Moved the new file into Linux GSG directory instead of\n common directory. Seems like the least bad solution of\n them all.\n \n Here, \"supported\" is defined not as \"doesn't produce error\n on a particular platform\", but rather is defined as \"actually\n works according to current codebase\". All command-line\n options have been traced through code to determine whether\n they actually do anything.\n \n As a result, even though some command-line options (such as\n \"--vmware-tsc-map\") are handled in eal_common_options (and\n thus are supposed to be supported on all platforms), they\n are nevertheless marked as Linux-specific. I believe this\n is a good standard to follow.\n \n It would also be good to include links to relevant PG\n sections for each parameters, but that can be done in\n the future. This is a good enough start, i think.\n\n .../freebsd_gsg/freebsd_eal_parameters.rst | 20 +++\n doc/guides/freebsd_gsg/index.rst | 1 +\n doc/guides/linux_gsg/eal_args.include.rst | 146 ++++++++++++++++++\n doc/guides/linux_gsg/index.rst | 1 +\n doc/guides/linux_gsg/linux_eal_parameters.rst | 118 ++++++++++++++\n doc/guides/sample_app_ug/intro.rst | 10 ++\n doc/guides/testpmd_app_ug/run_app.rst | 132 +---------------\n 7 files changed, 299 insertions(+), 129 deletions(-)\n create mode 100644 doc/guides/freebsd_gsg/freebsd_eal_parameters.rst\n create mode 100644 doc/guides/linux_gsg/eal_args.include.rst\n create mode 100644 doc/guides/linux_gsg/linux_eal_parameters.rst", "diff": "diff --git a/doc/guides/freebsd_gsg/freebsd_eal_parameters.rst b/doc/guides/freebsd_gsg/freebsd_eal_parameters.rst\nnew file mode 100644\nindex 000000000..b8dd3c7e8\n--- /dev/null\n+++ b/doc/guides/freebsd_gsg/freebsd_eal_parameters.rst\n@@ -0,0 +1,20 @@\n+..
