In kernel/sched.c, rebalance_tick is run periodically on each CPU. This
function takes its CPU's base sched domain and checks to see if has reached
its rebalance interval. If so, then it will run load_balance on that domain.
rebalance_tick then checks the parent sched_domain (if it exists), and the
parent of the parent and so forth.
In kernel/sched.c, trigger_load_balance() is run periodically on each CPU
through scheduler_tick(). It raises a softirq after the next regularly scheduled
rebalancing event for the current runqueue has arrived. The actual load
balancing workhorse, run_rebalance_domains()->rebalance_domains(), is then run
in softirq context (SCHED_SOFTIRQ).
The latter function takes two arguments: the current CPU and whether it was idle
at the time the scheduler_tick() happened and iterates over all sched domains
our CPU is on, starting from its base domain and going up the ->parent chain.
While doing that, it checks to see if the current domain has exhausted its
rebalance interval. If so, it runs load_balance() on that domain. It then checks
the parent sched_domain (if it exists), and the parent of the parent and so
forth.
Initially, load_balance() finds the busiest group in the current sched domain.
If it succeeds, it looks for the busiest runqueue of all the CPUs' runqueues in
that group. If it manages to find such a runqueue, it locks both our initial
CPU's runqueue and the newly found busiest one and starts moving tasks from it
to our runqueue. The exact number of tasks amounts to an imbalance previously
computed while iterating over this sched domain's groups.
