-Subject: [PATCH 1/4] Add virtual output support
-
-This patch is ported to weston 2.0.0.
-
-----------
-Author: Damian Hobson-Garcia <dhobsong@igel.co.jp>
-Date: Thu Apr 27 16:47:00 2017 +0900
-
-Following patch ported to Weston 1.11 with minor updates
- ----------
- Author: Grigory Kletsko <grigory.kletsko@cogentembedded.com>
- Date: Wed Nov 2 17:14:43 2016 +0300
-
- To enable virtual output set "virtual" property in core section
- to desirable number of virtual outputs. Then add settings to
- each virtual output in output sections. Name of the outputs
- will be virtual1, virtual2... etc.
