2014-06-11sna: Create a stable output name based on MST topologyChris Wilson
In order to provide persistent names for MST devices, which may change topology dynamically, the kernel exports a PATH blob. We can then use this path to generate the output name, and so reuse existing XID when a monitor is plugged back in. Based on the patch for -modesetting by Dave Airlie.

2014-06-10sna: Queue a flip after fixing up a failed flipChris Wilson
After a flip fails, we try to update the CRTC manually to new fb. However, the caller is still expecting to receive an event though the drm device to notify when the flips are complete. In order to maintain that ABI, we need to queue another flip after the fixup (to the currently bound fb). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2014-06-09sna/dri2: Avoid trying to flip between bo with different pitchesChris Wilson
It could happen that we create front/back buffers with different pitches. The kernel refuses to flip between such buffers, and so we will hit some fallback paths that try to fix up the failed flips. Circumvent such by avoiding the flip. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-09sna: Fixup normal flips between different pitchesChris Wilson
Apply the manual CRTC fixup in case pageflipping fails. This can happen if the pitches between the front and back differ for example. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-09sna/dri2: Allow TearFree flipping to individual CRTCChris Wilson
Baby step. We first take advantage of TearFree to allow us to redirect a single CRTC to the DRI2 frontbuffer and so allow a fullscreen game covering a single monitor to avoid expensive blits when running in a multi-monitor setup. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2014-06-08sna/dri2: Explicitly drain the pending event queue before swappingChris Wilson

2014-06-08sna/dri2: Mark frames under constructionChris Wilson

2014-06-08sna/dri2: Check the xchg against the Pixmap sizeChris Wilson

2014-06-07sna: Restore backlight when switching to VTChris Wilson
fbcon doesn't adjust the backlight when it takes over. Therefore if X performs a VT switch whilst its outputs are off, fbcon wakes up with no backlight and users are unhappy. Make the assumption that whoever takes over the VT will set the outputs as it desires, and that the failsafe value is to then turn the backlight to full.

2014-06-06sna: Hook up a backlight udev monitor for external changesChris Wilson
Changes to the backlights are notified through uevents. Hooking up a udev monitor to listen out for external changes to the backlight (e.g. through ACPI function keys, or by the user writing to /sys/class/backlight directly) is easier than enabling polling on the backlight sysfs file using X's select() mechanism. Since we listen to backlight changes, we have to be careful not to confuse the side-effects of disabling connectors (which may cause either ourselves or the kernel to turn off the backlight) with the user value. Many thanks to Alexander Mezin for the suggestion to use udev for tracking the notifications for external changes to the backlight.
