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 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/include/asm/topology.h | 2 + arch/arm/kernel/topology.c | 210 +++++++++++++++++++++++++++++++++++---- arch/x86/kernel/cpu/Makefile | 2 +- arch/x86/kernel/cpu/sched.c | 55 ---------- kernel/sched/features.h | 2 +- 5 files changed, 193 insertions(+), 78 deletions(-) delete mode 100644 arch/x86/kernel/cpu/sched.c -- 1.7.9.5
