Subject[PATCH v2 0/7] cpufreq: improve frequency invariance support
Date
Hi guys,

Please find below the changes to this series:

v1 -> v2:
- v1 can be found at [1]
- No cpufreq flags are introduced
- Previous patches 2/8 and 3/8 were squashed in this series under 1/7,
to ensure bisection.
- 2/7 was introduced as a proposal for Viresh's suggestion to use
policy->cur in the call to arch_set_freq_scale() and is extended to
support drivers that implement the target() callback as well
- Additional commit message changes are added to 1/7 and 2/7, to
clarify that the definition of arch_set_freq_scale() will filter
settings of the scale factor, if unwanted
- 3/7 disables setting of the scale factor for
CONFIG_BL_SWITCHER, as Dietmar suggested
- Small change introduced in 4/7 to disable cpufreq-based frequency
invariance for the users of the default arch_set_freq_scale() call
which will not actually set a scale factor
- build issue solved (reported by 0day test)
- v2 is based on linux-next 20200716
- all functional tests in v1 were repeated for v2

Let me know what you think!

Thank you,
Ionela.

Ionela Voinescu (3):
cpufreq: set invariance scale factor on transition end
arch_topology: disable frequency invariance for CONFIG_BL_SWITCHER
cpufreq: report whether cpufreq supports Frequency Invariance (FI)

Valentin Schneider (4):
cpufreq: move invariance setter calls in cpufreq core
arch_topology,cpufreq,sched/core: constify arch_* cpumasks
arch_topology,arm,arm64: define arch_scale_freq_invariant()
cpufreq: make schedutil the default for arm and arm64
