Subject: [Xenomai-core] xenomai preempting interrupt handler ?
Date: Thu, 08 Mar 2007 10:29:58 +0100 [thread overview]
Message-ID: <45EFD796.7050002@domain.hid> (raw)
Hi all,
using an oscilloscope I found that the AT91RM9200 spends up to 300µs in the
interrupt handler for ethernet controller.
Now I wonder if this interrupt handler will be preempted by Xenomai if there
is a high priority, periodic real time task? Thus will the duration of the
ethernet interrupt handler add the the worst case latency?
Thanks.
