  5Description:	RW. Card reactive sustained  (PL1) power limit in microwatts.
  6
  7		The power controller will throttle the operating frequency
  8		if the power averaged over a window (typically seconds)
  9		exceeds this limit. A read value of 0 means that the PL1
 10		power limit is disabled, writing 0 disables the
 11		limit. Writing values > 0 and <= TDP will enable the power limit.
 12
 13		Only supported for particular Intel Xe graphics platforms.
