I'm currently doing some stuff with SMP kernels, and I'd like to know
which task is currently running in which CPU. I know that the variable
"current" is a pointer to a struct task that is currently running in the
CPU executing that portion of code. However, I'm not completely sure how
to get which task is currently running in the other CPUs.
In particular, if smp_processor_id() returns me CPU 0, I'd like to know
which task is running in CPU 1 ( or 2 or 3 ).
The only solution that I found is to go through all the runqueue, and
check the "has_cpu" field and "processor" field ( similar to how the
goodness function work ). However, I think that is very inefficient.
Does anybody know of other ( more efficient ) way of doing this ? I'm
working with the 2.2.x series
Thanks in advance,
Hugo
