Hi All, What is significance of __ARCH_IRQ_EXIT_IRQS_DISABLED macro?
Hi Pradeep, This architecture specific macro if defined, means that the IRQs are guaranteed to be disabled when irq_exit() function is called. In such a case, the kernel may skip some instructions (disabling IRQs etc) .... and thus call __do_IRQ() instead of do_IRQ. Thanks, Rajat (PS: Though, I could not make out if there is any architecture that could have IRQs enabled at the time irq_exit() is called). -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
