Subject: [PATCH 0/5] Introduce camera subsystem and USB video device
Date: Mon, 27 Dec 2021 22:27:29 +0800	[thread overview]
Message-ID: <20211227142734.691900-1-pizhenwei@bytedance.com> (raw)

1, The full picture of this patch set:

	 +------------+camera(done)+-------------+
                      +----+-------+
                           |
         +-----------------+---------------------+
         |                 |                     |
  +------+------+     +----+-----+        +------+------+
  |builtin(done)|     |v4l2(done)|        |other drivers|
  +-------------+     +----------+        +-------------+

With this patch set, We can run a desktop VM (Ex Ubuntu-2004), several camera
APPs(cheese, kamoso, guvcview and qcam) work fine.

Some works still in working:
  1, hot-plug
  2, compat with live migration
  3, several actions defined in UVC SPEC
