In linux kernel since version 2.6.36 (release Date: 2010-10-20)  
Intel Calpella platforms support dynamic power sharing between the
CPU and GPU, maximizing performance in a given TDP. This driver,
along with the CPU frequency and i915 drivers, provides that
functionality. If in doubt, say Y here; it will only load on
supported platforms.
