When scheduler debug is enabled, building scheduling domains outputs
information about how the domains are laid out and to which root domain
each CPU (or sets of CPUs) belongs, e.g.:
CPU0 attaching sched-domain(s):
domain-0: span=0-5 level=MC
groups: 0:{ span=0 }, 1:{ span=1 }, 2:{ span=2 }, 3:{ span=3 }, 4:{ span=4 }, 5:{ span=5 }
CPU1 attaching sched-domain(s):
domain-0: span=0-5 level=MC
groups: 1:{ span=1 }, 2:{ span=2 }, 3:{ span=3 }, 4:{ span=4 }, 5:{ span=5 }, 0:{ span=0 }
[...]
span: 0-5 (max cpu_capacity = 1024)
The fact that latest line refers to CPUs 0-5 root domain doesn't however look
immediately obvious to me: one might wonder why span 0-5 is reported "again".
Make it more clear by adding "root domain" to it, as to end with the
following:
CPU0 attaching sched-domain(s):
domain-0: span=0-5 level=MC
groups: 0:{ span=0 }, 1:{ span=1 }, 2:{ span=2 }, 3:{ span=3 }, 4:{ span=4 }, 5:{ span=5 }
CPU1 attaching sched-domain(s):
domain-0: span=0-5 level=MC
groups: 1:{ span=1 }, 2:{ span=2 }, 3:{ span=3 }, 4:{ span=4 }, 5:{ span=5 }, 0:{ span=0 }
[...]
root domain span: 0-5 (max cpu_capacity = 1024)

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
