Subject: spin_lock_irqsave and multi-core
Date: Thu, 01 Apr 2010 09:59:33 +0800 [thread overview]
Message-ID: <4BB3FE05.6040800@alcatel-lucent.com> (raw)
I got a question when reading source code. Hope somebody can give me the
answer.
On multi-core system, spin_lock_irqsave() can stop all CPU cores
receiving interrupts?
If the answer is no, what we can do to disable external interrupt for
all CPU cores?
Thanks,
Gavin
