Furthermore, your driver does - not have to wait eg. for a big heavy SCSI interrupt to finish, - because the driver_lock spinlock is only used by your driver. - cli() on the other hand was used by many drivers, and extended - the critical section to the whole IRQ handler function - creating - serious lock contention. - - -to make the transition easier, we've still kept the cli(), sti(), -save_flags(), save_flags_cli() and restore_flags() macros defined -on UP systems - but their usage will be phased out until 2.6 is -released. - -drivers that want to disable local interrupts (interrupts on the -current CPU), can use the following five macros: - - local_irq_disable(), local_irq_enable(), local_save_flags(flags), - local_irq_save(flags), local_irq_restore(flags) - -but beware, their meaning and semantics are much simpler, far from -that of the old cli(), sti(), save_flags(flags) and restore_flags(flags) -SMP meaning: - - local_irq_disable() => turn local IRQs off - - local_irq_enable() => turn local IRQs on - - local_save_flags(flags) => save the current IRQ state into flags. The - state can be on or off.
