Subject: About interrupt handler
Date: Wed, 22 Feb 2012 23:59:37 +0800 [thread overview]
Message-ID: <tencent_1CD935556F37F40908FD2076@qq.com> (raw)
hi all,
I'm begin to learn the Kernel and i'm reading <<Linux kernel development>>.It says "This is an important point, always keep in mind that all interrupt handler has interrupted other code(possibly even another interrupt handler on a different line)".What i am not able to understand is how a interrupt handler be interrupted ? DID NOT it uninterrupted?
------------------
best regards?
