Subject: Interrupt Bottom Half Scheduling
Date: Mon, 14 Feb 2011 14:31:43 -0800	[thread overview]
Message-ID: <AANLkTimGobdGMgnc8bVJTvYtH4Tjn2ZVmroeFA2s06WD@mail.gmail.com> (raw)

How is the scheduling of the hrtimers softirq thread handled?

When querying the RT priority of the hrtimer softirq, I get a priority
of 50.  But when running a priority 99 thread, we still seem to be
getting interrupted.  Shouldn't the hrtimer softirq be put off until
the CPU is idle or a lower priority task is running?

Thanks,
Pete
