From fabb657005edbbcb0d13ee49a40f1f4b042a1d19 Mon Sep 17 00:00:00 2001 From: Maxim Shchetynin Date: Sat, 5 Jul 2008 05:05:39 +1000 Subject: powerpc/spufs: add atomic busy_spus counter to struct cbe_spu_info As nr_active counter includes also spus waiting for syscalls to return we need a seperate counter that only counts spus that are currently running on spu side. This counter shall be used by a cpufreq governor that targets a frequency dependent from the number of running spus.
