Subject: [question] on which cpu an interrupt controller will raise an irq ?
Date: Sun, 07 Dec 2014 21:42:48 +0100 [thread overview]
Message-ID: <5484BBC8.7080304@linaro.org> (raw)
Hi all,
I am not very familiar with the interrupt subsystem, so sorry if this
sounds a stupid question.
IIUC, when a interrupt happens on a SMP system and if there is no
affinity set for it, it is delivered following a scheme decided by the
interrupt controller.
For example, for the APIC, there is a round robin behaviour, so an
interrupt will be raised on cpu0, then cpu1, and so on ...
Is there a way to know on which cpu a controller will raise the interrupt ?
Thanks in advance
-- Daniel
