Subject: [PATCH v3 3/4] media: venus: Add interface for load per core
Date: Tue, 25 Jun 2019 21:57:23 +0530 [thread overview]
Message-ID: <1561480044-11834-4-git-send-email-amasule@codeaurora.org> (raw)
In-Reply-To: <1561480044-11834-1-git-send-email-amasule@codeaurora.org>
Add and interface to calculate load per core. Also,
add an interface to get maximum cores available with
video. This interface is preparation for updating core
selection.
