Architecture.

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.

processor will not only be able to run at lower speed,
but also at lower core voltage.

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.
