Subject: Timer Selection
Date: Sun, 10 Sep 2006 18:37:12 +0800	[thread overview]
Message-ID: <a2ebde260609100337xda27723geae84190d90293c1@mail.gmail.com> (raw)
In-Reply-To: <a2ebde260609100334v65bf5e4fx754e3b00576bfb9f@mail.gmail.com>

In i386 architecture, there are five timers as candidates in the
selection of "cur_timer." I feel among the five only two types can be
used as Kernel base timer, HPET and PIT. Kernel base timer is the
timer trigger timer_interrupt() periodically. Namely, the timer
installed on IRQ 0 in i386 architecture.

Is the above understanding correct? Particularly I want to confirm
which timers can be used as Kernel base timer.

Thanks.

Feng,Dong
