how to check a specific irq is disabled in linux kernel?
by Tony.He90 from LinuxQuestions.org on (#6DEQC)
Hi,
I want to know how to check a specific irq is disabled in linux kernel. I can not use the function of irqs_disabled() because irqs_disabled() is to know the state of interrupt system. My question is similar
to this one[1] in stackoverflow. However, no answer there.
