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
As there may be some latency between the wakeup and the queue, do a final check if there is a pending vblank event before we decide whether to chain up or perform an immediate flip. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-08sna/dri2: Mark frames under constructionChris Wilson
As we may recurse into the vblank handler whilst waiting for the TearFree shadow, we need to be careful that we do not queue the frame from the vblank handler that we are in the process of constructing. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
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.

2014-06-05sna/dri2: Enable immediate buffer exchangesChris Wilson

2014-06-02uxa: Restructure DRM event handling.Keith Packard
This refactors the drm interrupt handling logic quite a bit, both to allow for either DRI2 or Present handlers, but also to eliminate passing pointers through the kernel. Passing pointers left the kernel holding the only reference to some internal X server data structures. After a server reset, the X server would end up using stale pointers stored in those structures. Using simple integers makes it possible to empty the queue of pending interrupt data and then ignore the stale kernel data.

2014-06-02uxa: Support 64-bit MSC values. Handle kernel vageries about MSC reportingKeith Packard
The kernel sometimes reports bogus MSC values, especially when suspending and resuming the machine. Deal with this by tracking an offset to ensure that the MSC seen by applications increases monotonically, and at a reasonable pace. Also, provide a full 64 bits of MSC value by noticing wrapping and tracking the high 32-bits of MSC separately.
