Subject: [PATCH 2/2] venus: core: vote for video-mem icc path and change avg, peak bw
Date:   Tue,  8 Sep 2020 09:14:38 +0530
Message-Id: <1599536678-4666-1-git-send-email-mansur@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Currently we are voting for venus0-ebi path during buffer processing
with an average bandwidth of all the instances and unvoting during
session release.

While video streaming when we try to do XO-SD using the command
"echo mem > /sys/power/state command" , device is not entering
to suspend state and from interconnect summary seeing votes for venus0-ebi

Corrected this by voting for venus0-ebi path in venus_runtime_resume
and unvote during venus_runtime_suspend.
