  -- == Description
  --
  -- This extension adds the device coherent and device uncached memory
  -- types. Any device accesses to device coherent memory are automatically
  -- made visible to any other device access. Device uncached memory
  -- indicates to applications that caches are disabled for a particular
  -- memory type, which guarantees device coherence.
  --
  -- Device coherent and uncached memory are expected to have lower
  -- performance for general access than non-device coherent memory, but can
  -- be useful in certain scenarios; particularly so for debugging.
