This patchset consolidates several changes in the capacity and the usage
tracking of the CPU. It provides a frequency invariant metric of the usage of
CPUs and generally improves the accuracy of load/usage tracking in the
scheduler. The frequency invariant metric is the foundation required for the
consolidation of cpufreq and implementation of a fully invariant load tracking.
These are currently WIP and require several changes to the load balancer
(including how it will use and interprets load and capacity metrics) and
extensive validation. The frequency invariance is done with
arch_scale_freq_capacity and this patchset doesn't provide the backends of
the function which are architecture dependent.
As discussed at LPC14, Morten and I have consolidated our changes into a single
patchset to make it easier to review and merge.
During load balance, the scheduler evaluates the number of tasks that a group
of CPUs can handle. The current method assumes that tasks have a fix load of
SCHED_LOAD_SCALE and CPUs have a default capacity of SCHED_CAPACITY_SCALE.
This assumption generates wrong decision by creating ghost cores or by
removing real ones when the original capacity of CPUs is different from the
default SCHED_CAPACITY_SCALE. With this patch set, we don't try anymore to
evaluate the number of available cores based on the group_capacity but instead
we evaluate the usage of a group and compare it with its capacity.
This patchset mainly replaces the old capacity_factor method by a new one and
keeps the general policy almost unchanged. These new metrics will be also used
in later patches.
The CPU usage is based on a running time tracking version of the current
implementation of the load average tracking. I also have a version that is
based on the new implementation proposal [1] but I haven't provide the patches
and results as [1] is still under review. I can provide change above [1] to
change how CPU usage is computed and to adapt to new mecanism.
Change since V7

arm64-allnoconfig
arm-multi_v7_defconfig
x86_64-defconfig
From: Mark Brown <broonie(a)linaro.org>
The only requirement the scheduler has on cluster IDs is that they must
be unique. When enumerating the topology based on MPIDR information the
kernel currently generates cluster IDs by using the first level of
affinity above the core ID (either level one or two depending on if the
core has multiple threads) however the ARMv8 architecture allows for up
to three levels of affinity. This means that an ARMv8 system may
contain cores which have MPIDRs identical other than affinity level
three which with current code will cause us to report multiple cores
with the same identification to the scheduler in violation of its
uniqueness requirement.
Ensure that we do not violate the scheduler requirements on systems that
uses all the affinity levels by incorporating both affinity levels two
and three into the cluser ID when the cores are not threaded.
While no currently known hardware uses multi-level clusters it is better
to program defensively, this will help ease bringup of systems that have
them and will ensure that things like distribution install media do not
need to be respun to replace kernels in order to deploy such systems.
In the worst case the system will work but perform suboptimally until a
kernel modified to handle the new topology better is installed, in the
best case this will be an adequate description of such topologies for
the scheduler to perform well.
