Subject: Question on priorities with CAN
Date: Thu, 19 Sep 2019 10:40:53 +0200 [thread overview]
Message-ID: <20190919084053.GB1446@x1.vandijck-laurijssen.be> (raw)
Hey,
I work on a beaglebone-like board using the AM335x can chip, with an RT
kernel.
The can irq task is by default rt prio 50.
I have a process running on rt prio 10 using CAN_RAW socket.
I see that softirqd runs on regular timeslicing.
Do CAN frames need to pass through the softirqd in order to arrive
on my process?
I would need to elevate the softirqd's rt prio also in that case?
Kind regards,
Kurt
