I have noticed this problem: root@192.168.1.253:~# cat /proc/loadavgrt 1.00 1.00 1.00 0/52 1158 root@192.168.1.253:~# cat /proc/loadavg 0.00 0.00 0.02 1/52 1159 root@192.168.1.253:~# So I am curious, if possible, user can switch softirq-threads or IRQs RT tasks to non-RT tasks for slow hardware or least important hardware for NON-RT tasks. So this will improve RT behaviour. By default, all softirq-threads or IRQs will be RT task but if there is some option user can switch it to NON-RT task then it will be good.
