Hi Marc,
In the Linux kernel, we can not adjust the interrupt Priority, For all the interrupts, the interrupt Priority are fixed to 0xa0.
In some scenarios, it needs to change the Priority. so I want to upstream a serie patch to support to change the Priority through procfs. do you agree I upstream this feature? thanks~
