This patchset creates an arch_scale_freq_power function for ARM, which is used to set the relative capacity of each core of a big.LITTLE system. It also removes the broken power estimation of x86.
Modification since v3: - Add comments - Add optimization for SMP system - Ensure that capacity of a CPU will be at most 1 Modification since v2: - set_power_scale function becomes static - Rework loop in update_siblings_masks - Remove useless code in parse_dt_topology Modification since v1: - Add and update explanation about the use of the table and the range of the value - Remove the use of NR_CPUS and use nr_cpu_ids instead - Remove broken power estimation of x86 Peter Zijlstra (1): sched, x86: Remove broken power estimation Vincent Guittot (4): ARM: topology: Add arch_scale_freq_power function ARM: topology: factorize the update of sibling masks ARM: topology: Update cpu_power according to DT information sched: cpu_power: enable ARCH_POWER arch/arm/kernel/topology.c | 239 ++++++++++++++++++++++++++++++++++++++---- arch/x86/kernel/cpu/Makefile | 2 +- arch/x86/kernel/cpu/sched.c | 55 ---------- kernel/sched/features.h | 2 +- 4 files changed, 219 insertions(+), 79 deletions(-) delete mode 100644 arch/x86/kernel/cpu/sched.c -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
