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)
