Description:
Andrea Righi has started
a blog series on writing a user-space CPU scheduler with the BPF-based extensible scheduler class : .select_cpu() implements the logic to assign a target CPU to a task
that wants to run, typically you have to decide if you want to keep
the task on the same CPU or if it needs to be migrated to a
different one (for example if the current CPU is busy); if we can
find an idle CPU at this stage theres no reason to call the
scheduler, the task can be immediately dispatched here.
