Subject: [PATCH AUTOSEL 5.8 12/29] interconnect: Show bandwidth for disabled paths as zero in debugfs
Date: Mon, 14 Sep 2020 09:03:41 -0400	[thread overview]
Message-ID: <20200914130358.1804194-12-sashal@kernel.org> (raw)
In-Reply-To: <20200914130358.1804194-1-sashal@kernel.org>

From: Matthias Kaehlcke <mka@chromium.org>

[ Upstream commit b1910c6b9983817160e04d4e87b2dc1413c5361a ]

For disabled paths the 'interconnect_summary' in debugfs currently shows
the orginally requested bandwidths. This is confusing, since the bandwidth
requests aren't active. Instead show the bandwidths for disabled
paths/requests as zero.
