Topically,at the complection of a device I/O,
a single interrupt is raised and appropriately handled by the host processor.
In certain settings,however the code that is to be executed
at the complection of the I/O can be broken into two separate pieces,
one of which executes immediately after the I/O completes and
schedules a second interrupt for the remaining piece of code to be executed at a later time.
(1) What is the purpose of using this
two pieces strategy in the design of
interrupt handles?
(2)How to notice the scheduler to
complete the remaining piece of code?
(3)In which cases mutual exclusive lock
will be considered or not?
這題看不太懂題目在問的是什麼@@
不好意思...因為手機排版，
可能有點亂，請見諒： )
感謝撥冗解答！
