653aa7ffc01SJesse Barnes	  Intel Calpella platforms support dynamic power sharing between the
654aa7ffc01SJesse Barnes	  CPU and GPU, maximizing performance in a given TDP.  This driver,
655aa7ffc01SJesse Barnes	  along with the CPU frequency and i915 drivers, provides that
656aa7ffc01SJesse Barnes	  functionality.  If in doubt, say Y here; it will only load on
657aa7ffc01SJesse Barnes	  supported platforms.

66935f0ce03SVernon Mauery	 If the proper BIOS support is found the driver will load and create
