Subject: [PATCH 3/3] rpmsg: glink: Use best fit intent during tx
Date: Wed, 18 Oct 2017 18:10:18 -0700 [thread overview]
Message-ID: <1508375418-15611-4-git-send-email-clew@codeaurora.org> (raw)
In-Reply-To: <1508375418-15611-1-git-send-email-clew@codeaurora.org>
Intents can vary in size, try to find the best fitting remote intent
instead of first fit when sending a message to the remote proc.
