Dear Sirs:
I'm studying Linux-smp and met with some difficulties during my
studies. I want to ask some questions about interrupt mechanism in the
Linux-smp system. I wonder whether you can answer me or give me some advice?
I have seen the MP Specification 1.4, I learned that any interrupt can
be handled by any of the processors available in the system. But I still
want to know some details about how the interrupts be handled by linux-smp.
If an interrupt comes and all the processors want to obtain the kernel lock
to handle the interrupt( suppose that no processor hold the kernel lock
currently) ,will they cause contention?And who will obtain the lock
finally?If one processor has obtained the lock ,whether 'he' should inform
the others that there is no need to handle the interrupt by them any more?Or
in what way do the processors correspond with each other?
Expecting for your answer and thank you very much for your kindness and
attention.
