Subject: [dpdk-dev] [PATCH v2 1/8] eal: use different constructor priorities for initcalls
Date: Mon, 20 Feb 2017 15:17:35 +0100 [thread overview]
Message-ID: <1487600262-14382-2-git-send-email-jblunck@infradead.org> (raw)
In-Reply-To: <1487600262-14382-1-git-send-email-jblunck@infradead.org>
In-Reply-To: <1487152929-23627-1-git-send-email-jblunck@infradead.org>
This introduces different initcall macros to allow for late registration of
the virtual device bus.
