Subject: Why not distribute timer handlers on CPUs on SMP
Date: Wed, 6 Oct 2010 09:05:52 +0800 [thread overview]
Message-ID: <2B624B3F-9338-4336-B4F6-D61B476DA255@gmail.com> (raw)
Hello,
I am just curious about why handle the timer functions on a CPU serially but not distribute them over CPUs
even on a SMP system?
The timer wheel handler function __run_timers() serializes the timer functions on a CPU,
is there any design consideration that handling timers on a CPU is more reasonable than distribute them
over CPUs?
Best regards
Shan Hai
