- Energy scheduling:
- Consolidate how the max compute capacity is
used in the scheduler and how we calculate
the frequency for a level of utilization.
- Rework interface between the scheduler and
the schedutil governor
- Simplify the util_est logic
- Deadline scheduler:
- Work more towards reducing SCHED_DEADLINE
starvation of low priority tasks (e.g., SCHED_OTHER)
tasks when higher priority tasks monopolize CPU
cycles, via the introduction of 'deadline servers'
(nested/2-level scheduling).
"Fair servers" to make use of this facility are
not introduced yet.
- EEVDF:
- Introduce O(1) fastpath for EEVDF task selection
- NUMA balancing:
- Tune the NUMA-balancing vma scanning logic some more,
to better distribute the probability
of a particular vma getting scanned.
- Plus misc fixes, cleanups and updates.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
