Subject: [PATCH 4/5] media: venus: Add interface for load per core
Date: Tue, 11 Jun 2019 11:35:29 +0530	[thread overview]
Message-ID: <1560233130-27264-5-git-send-email-amasule@codeaurora.org> (raw)
In-Reply-To: <1560233130-27264-1-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.
