kmssink: add sync support for secondary pipes The vblank event request must specify the crtc for which to request the event. This fixes kmssink synchronisation for crtcs other than the first. https://bugzilla.gnome.org/show_bug.cgi?id=765064

kmssink: add dmabuf support This patch will enable the import of dmabufs into a KMS buffer using the PRIME kernel interface. If the driver does not support prime import, the method is skipped. It has been tested with a Freescale I.MX6 board. https://bugzilla.gnome.org/show_bug.cgi?id=761059

kmssink: add mode setting and base plane rendering The kmssink assumed that the mode was already set by another application and used an overlay plane for displaying the frames. Use the preferred mode of the monitor and render to the base plane if the crtc does not have a valid mode. https://bugzilla.gnome.org/show_bug.cgi?id=773473 Signed-off-by: Víctor Manuel Jáquez Leal <vjaquez@igalia.com>

kmssink: configure display mode during set_caps Configure the display mode when setting the negotiated caps instead of during showing the first frame. A framebuffer is required to set the mode. Allocate a buffer object according to the negotiated caps and use it to set the mode. This buffer object cannot be freed until another page flip happened on the crtc (i.e., until the first frame is rendered). https://bugzilla.gnome.org/show_bug.cgi?id=773473 Signed-off-by: Víctor Manuel Jáquez Leal <vjaquez@igalia.com>

kmssink: Track cached kmsmem and clear them on drain In this patch we keep track of the cached kmsmem in a way that we can clear the cache during the drain process. This release the framebuffer before waiting for the next vblank, hence add support for DRM driver (like Intel one) that release the associated DMABuf reference asynchronously. https://bugzilla.gnome.org/show_bug.cgi?id=782774
