    Subjectwhen interrupt came, the kernel save pt_regs->eip always the same?
    These day i wanted get cpu context ,when interrupt came.BUT i
    found when interrupt came kernel saved cpu context in struct pt_regs
    and delivered to do_IRQ ,and i print the pt_regs->eip,they alway same
    on the same interrupt?
    The interrupt can come anytime,i think the eip will be very
    different every time.BUT i debug kernel ,print eip in the function
    do_IRQ,found it didn't run as i thought.Can anybody tell me why?

    sincerely yours
