Subject: [PATCH 4/5] media: venus: Add interface for load per core
Date:   Thu, 30 May 2019 19:28:27 +0530
Message-Id: <1559224708-6039-5-git-send-email-amasule@codeaurora.org>
In-Reply-To: <1559224708-6039-1-git-send-email-amasule@codeaurora.org>
References: <1559224708-6039-1-git-send-email-amasule@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
