This 4 way SMT benefits from dynamic power updates that arch_scale_smt_power was designed to provide. The first patch fixes a generic scheduler bug necessary for arch_scale_smt to properly function. The second patch implements arch_scale_smt_power for powerpc, and in particular for Power7 processors. Version 2 changes: - Drop Patch 1 from the original series since it's in the -tip tree now - Move enabling the cpu feature into it's own patch (now patch 1) - Add stubbing out broken x86 implementation to patch 1 - clean up coding style in patch 2 --- Joel Schopp (2): powerpc: implement arch_scale_smt_power for Power7 sched: enable ARCH_POWER arch/powerpc/include/asm/cputable.h | 3 +- arch/powerpc/kernel/smp.c | 52 ++++++++++++++++++++++++++++++++++++ arch/x86/kernel/cpu/sched.c | 6 +--- kernel/sched_features.h | 2 - 4 files changed, 57 insertions(+), 6 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
