Since all PMDs are built in pretty much the same way, the logic\nfor building each PMD, including extracting the pmdinfo, is included in the\ntop level build file. This means that each individual driver class only\nneeds to specify its default dependencies and a few naming conventions, and\neach driver only needs to specify it's source files, headers, etc.\n\nSigned-off-by: Bruce Richardson <bruce.richardson@intel.com>\n---\n drivers/meson.build | 121 ++++++++++++++++++++++++++++++++++++++++++++++++++++\n meson.build | 3 +-\n 2 files changed, 123 insertions(+), 1 deletion(-)\n create mode 100644 drivers/meson.build", "diff": "diff --git a/drivers/meson.build b/drivers/meson.build\nnew file mode 100644\nindex 000000000..35aa568c9\n--- /dev/null\n+++ b/drivers/meson.build\n@@ -0,0 +1,121 @@\n+# BSD LICENSE\n+#\n+# Copyright(c) 2017 Intel Corporation.
