From a7331e5cb2cc680ac30337cec5299956a8454ced Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Sat, 22 Oct 2011 10:36:19 +0200 Subject: drm: Introduce "Virtual" connectors and encoders This will allow us to attach various properties specific to virtual monitors in the future. Note that we don't export an EDID property for "Virtual" connectors.

Otherwise "smart" window managers would turn on Xorg outputs that we don't want to be on. This reinstates the update_layout and adds the following information to the modesetting system. a) Connection status <-> Equivalent to real hardware connection status b) Preferred mode <-> Equivalent to real hardware reading EDID c) Host window position <-> Equivalent to a real hardware scanout address dynamic register. It should be noted that there is no assumption here about what should be displayed and where. Only how to access the host windows. This also bumps minor to signal availability of the new IOCTL.
