These provide crtc-id based functions instead of pipe-number, while also offering higher resolution time (ns) and wider frame count (64) as required by the Vulkan API. v2: * Check for DRIVER_MODESET in new crtc-based vblank ioctls Failing to check this will oops the driver. * Ensure vblank interupt is running in crtc_get_sequence ioctl The sequence and timing values are not correct while the interrupt is off, so make sure it's running before asking for them. * Short-circuit get_sequence if the counter is enabled and accurate Steal the idea from the code in wait_vblank to avoid the expense of drm_vblank_get/put * Return active state of crtc in crtc_get_sequence ioctl Might be useful for applications that aren't in charge of modesetting? * Use drm_crtc_vblank_get/put in new crtc-based vblank sequence ioctls Daniel Vetter prefers these over the old drm_vblank_put/get APIs. * Return s64 ns instead of u64 in new sequence event Suggested-by: Daniel Vetter <daniel@ffwll.ch> Suggested-by: Ville Syrjälä <ville.syrjala@linux.intel.com> v3: * Removed FIRST_PIXEL_OUT_FLAG * Document that the timestamp in the query and event are that of the first pixel leaving the display engine for the display (using the same wording as the Vulkan spec).
