From: Bruce Richardson Date: Mon, 27 Jan 2020 14:28:22 +0000 (+0000) Subject: build: allow using wildcards to disable drivers X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ab9407c3addde1eee0f93e7c3491536cd4db4369;p=dpdk.git build: allow using wildcards to disable drivers Rather than having to explicitly list each and every driver to disable in a build, we can use a small python script and the python glob library to expand out the wildcards. This means that we can configure meson using e.g. meson -Ddisable_drivers=crypto/*,event/* build to do a build omitting all the crypto and event drivers. Explicitly specified drivers e.g. net/i40e, work as before, and can be mixed with wildcarded drivers as required.
