If the architecture that you are using supports the kernel option

option will prevent the use of software breakpoints because it

#### cli()/sti() removal guide, started by Ingo Molnar <mingo@redhat.com>
|
|
||||||
|
|
||||||
|
|
||||||
as of 2.5.28, five popular macros have been removed on SMP, and
|
|
||||||
are being phased out on UP:
|
|
||||||
|
|
||||||
cli(), sti(), save_flags(flags), save_flags_cli(flags), restore_flags(flags)
|
|
||||||
|
|
||||||
until now it was possible to protect driver code against interrupt
|
|
||||||
handlers via a cli(), but from now on other, more lightweight methods
|
|
||||||
have to be used for synchronization, such as spinlocks or semaphores.
|
|
||||||
|
|
||||||
for example, driver code that used to do something like:
|
|
||||||
|
|
||||||
struct driver_data;
|
|
||||||
|
|
||||||
irq_handler (...)
|
|
||||||
{
|
|
||||||
....
|
|
||||||
driver_data.finish = 1;
|
|
||||||
driver_data.new_work = 0;
|
|
||||||
....
|
|
||||||
}
|
|
||||||
|
|
||||||
...
|
|
||||||
|
|
||||||
ioctl_func (...)
|
|
||||||
{
|
|
||||||
...
|
|
||||||
cli();
|
|
||||||
...
|
|
||||||
driver_data.finish = 0;
|
|
||||||
driver_data.new_work = 2;
|
|
||||||
...
|
|
||||||
sti();
|
|
||||||
...
|
|
||||||
}
|
|
||||||
|
|
||||||
was SMP-correct because the cli() function ensured that no
|
|
||||||
interrupt handler (amongst them the above irq_handler()) function
|
|
||||||
would execute while the cli()-ed section is executing.
|
|
||||||
|
|
||||||
but from now on a more direct method of locking has to be used:
|
|
||||||
|
|
||||||
DEFINE_SPINLOCK(driver_lock);
|
|
||||||
struct driver_data;
|
|
||||||
|
|
||||||
irq_handler (...)
|
|
||||||
{
|
|
||||||
unsigned long flags;
|
|
||||||
....
|
|
||||||
spin_lock_irqsave(&driver_lock, flags);
|
|
||||||
....
|
|
||||||
driver_data.finish = 1;
|
|
||||||
driver_data.new_work = 0;
|
|
||||||
....
|
|
||||||
spin_unlock_irqrestore(&driver_lock, flags);
|
|
||||||
....
|
|
||||||
}
|
|
||||||
|
|
||||||
...
|
|
||||||
|
|
||||||
ioctl_func (...)
|
|
||||||
{
|
|
||||||
...
|
|
||||||
spin_lock_irq(&driver_lock);
|
|
||||||
...
|
|
||||||
driver_data.finish = 0;
|
|
||||||
driver_data.new_work = 2;
|
|
||||||
...
|
|
||||||
spin_unlock_irq(&driver_lock);
|
|
||||||
...
|
|
||||||
}
|
|
||||||
|
|
||||||
the above code has a number of advantages:
|
|
||||||
|
|
||||||
- the locking relation is easier to understand - actual lock usage
|
|
||||||
pinpoints the critical sections. cli() usage is too opaque.
|
|
||||||
Easier to understand means it's easier to debug.
|
|
||||||
|
|
||||||
- it's faster, because spinlocks are faster to acquire than the
|
|
||||||
potentially heavily-used IRQ lock. 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. (on some
|
|
||||||
architectures there's even more bits in it.)
|
|
||||||
|
|
||||||
local_irq_save(flags) => save the current IRQ state into flags and
|
|
||||||
disable interrupts.
|
|
||||||
|
|
||||||
local_irq_restore(flags) => restore the IRQ state from flags.
|
|
||||||
|
|
||||||
(local_irq_save can save both irqs on and irqs off state, and
|
|
||||||
local_irq_restore can restore into both irqs on and irqs off state.)
|
|
||||||
|
|
||||||
another related change is that synchronize_irq() now takes a parameter:
|
|
||||||
synchronize_irq(irq). This change too has the purpose of making SMP
|
|
||||||
synchronization more lightweight - this way you can wait for your own
|
|
||||||
interrupt handler to finish, no need to wait for other IRQ sources.
|
|
||||||
|
|
||||||
|
|
||||||
why were these changes done? The main reason was the architectural burden
|
|
||||||
of maintaining the cli()/sti() interface - it became a real problem. The
|
|
||||||
new interrupt system is much more streamlined, easier to understand, debug,
|
|
||||||
and it's also a bit faster - the same happened to it that will happen to
|
|
||||||
cli()/sti() using drivers once they convert to spinlocks :-)
