	  The SPU file system is used to access Synergistic Processing

	help
	  This option causes SPE local stores to be mapped in process
	  address spaces using 64K pages while the rest of the kernel
	  uses 4K pages. This can improve performances of applications
	  using multiple SPEs by lowering the TLB pressure on them.

	  Select this, if you want to use the PMI interface

	  PMI (Platform Management Interrupt) is a way to

	  It is used in some IBM Cell blades.

	  This governor checks for spu usage to adjust the cpu frequency.
	  If no spu is running on a given cpu, that cpu will be throttled to
	  the minimal possible frequency.
