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
