| |
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
