This extension provides fences and frame count information to direct
display contexts. It uses new kernel ioctls to provide 64-bits of
vblank sequence and nanosecond resolution.
v2: Adopt Jason Ekstrand's coding conventions
Declare variables at first use, eliminate extra whitespace between
types and names. Wrap lines to 80 columns.
Add extension to list in alphabetical order
Suggested-by: Jason Ekstrand <jason.ekstr...@intel.com>
v3: Adapt to WSI fence API change. It now returns VkResult and
no longer has an option for relative timeouts.
v4: wsi_register_display_event and wsi_register_device_event now
use the default allocator when NULL is provided, so remove the
computation of 'alloc' here.
