From cd2b89e7e8c036903e7fa0c3dceca25e755fe78d Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Tue, 25 Oct 2011 23:35:53 +0200 Subject: vmwgfx: Reinstate the update_layout ioctl We need to redefine a connector as "connected" if it matches a window in the host preferred GUI layout. 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.
