[PATCH v7 00/11] powerpc/powernv/cpuidle: Add support for POWER ISA v3 idle states

2016-07-07 Thread Shreyas B. Prabhu
POWER ISA v3 defines a new idle processor core mechanism. In summary, a) new instruction named stop is added. This instruction replaces instructions like nap, sleep, rvwinkle. b) new per thread SPR named PSSCR is added which controls the behavior of stop instruction.
