Subject: [PATCH AUTOSEL 5.4 04/20] media: uvcvideo: Quirk for autosuspend in Logitech B910 and C910
Date: Fri, 3 Mar 2023 16:47:50 -0500 [thread overview]
Message-ID: <20230303214806.1453287-4-sashal@kernel.org> (raw)
In-Reply-To: <20230303214806.1453287-1-sashal@kernel.org>
From: Ricardo Ribalda <ribalda@chromium.org>
[ Upstream commit 136effa754b57632f99574fc4a3433e0cfc031d9 ]
Logitech B910 and C910 firmware are unable to recover from a USB
autosuspend. When it resumes, the device is in a state where it only
produces invalid frames. Eg:
$ echo 0xFFFF > /sys/module/uvcvideo/parameters/trace # enable verbose log
$ yavta -c1 -n1 --file='frame#.jpg' --format MJPEG --size=1920x1080 /dev/video1

...(loop)...
The devices can leave this invalid state if the alternate setting of
the streaming interface is toggled.
This patch adds a quirk for this device so it can be autosuspended
properly.
