Subject: Changing Kernel thread priorities
Date: Mon, 6 Jun 2011 13:47:16 +0200	[thread overview]
Message-ID: <4DECBE44.2070803@unican.es> (raw)
In-Reply-To: <4DEA255B.2050503@unican.es>

I am writing a driver which has one kernel thread associated with it.
I want to change the priority of this thread, so that I can specify the 
order in which it is scheduled following an interrupt.
I'm using:

  sched_setscheduler(struct task_struct *, int, struct sched_param *);

but it doesn't work. I tried to change the priority from the 
init_module, and also from the Kernel Thread, but there is no way.

Kernel version is 2.6.31-11-rt

What do I call to change a kernel thread priority?

Thanks you very much

Mónica
