Hello everyone,

This set will switch the users of pm_runtime_put_autosuspend() to
__pm_runtime_put_autosuspend() while the former will soon be re-purposed
to include a call to pm_runtime_mark_last_busy(). The two are almost
always used together, apart from bugs which are likely common. Going
forward, most new users should be using pm_runtime_put_autosuspend().

Once this conversion is done and pm_runtime_put_autosuspend() re-purposed,
I'll post another set to merge the calls to __pm_runtime_put_autosuspend()
and pm_runtime_mark_last_busy().

The diff in these patches have been generated using the following

That sounds like it could cause a lot of churns.

Why not add a new helper function that does the
pm_runtime_put_autosuspend() and the pm_runtime_mark_last_busy()

rather than having this intermediate step?

Kind regards

I think the API would be nicer if we used the shortest and simplest
function names for the most common use cases. Following
pm_runtime_put_autosuspend() with pm_runtime_mark_last_busy() is that
most common use case. That's why I like Sakari's approach of repurposing
pm_runtime_put_autosuspend(), and introducing
__pm_runtime_put_autosuspend() for the odd cases where
pm_runtime_mark_last_busy() shouldn't be called.

That's ok for me. However this patch series isn't the optimal path to
there because most drivers (i.e. those that already today do
pm_runtime_mark_last_busy() in combination with
pm_runtime_put_autosuspend()) have to be patched twice.

The saner route is: Only convert the drivers with a sole
pm_runtime_put_autosuspend() (i.e. without pm_runtime_mark_last_busy())
to __pm_runtime_put_autosuspend(). Then add the mark_last_busy() bits to
pm_runtime_put_autosuspend() and then drop the explicit calls to
pm_runtime_mark_last_busy() before pm_runtime_put_autosuspend().

(Note this doesn't take into account Rafael's position that
pm_runtime_put() might be the saner option. My argument applies for that
conversion analogously.)

Best regards
Uwe

Okay, so the reason for this approach is because we couldn't find a
short and descriptive name that could be used in favor of
pm_runtime_put_autosuspend(). Let me throw some ideas at it and maybe
you like it - or not. :-)

I don't know what options you guys discussed, but to me the entire
"autosuspend"-suffix isn't really that necessary in my opinion. There
are more ways than calling pm_runtime_put_autosuspend() that triggers
us to use the RPM_AUTO flag for rpm_suspend(). For example, just
calling pm_runtime_put() has the similar effect.

Moreover, it's similar for pm_runtime_mark_last_busy(), it's called
during rpm_resume() too, for example. So why bother about having
"mark_last_busy" in the new name too.

That said, my suggestion is simply "pm_runtime_put_suspend".

If you don't like it, I will certainly not object to your current
approach, even if I think it leads to unnecessary churns.

I like the idea at least :-)

To be honest, I'm lost there. pm_runtime_put() calls
__pm_runtime_idle(RPM_GET_PUT | RPM_ASYNC), while
pm_runtime_put_autosuspend() calls __pm_runtime_suspend(RPM_GET_PUT |
RPM_ASYNC | RPM_AUTO).

Can we do even better, and make pm_runtime_put() to handle autosuspend
automatically when autosuspend is enabled ?

__pm_runtime_idle() ends up calling rpm_idle(), which may call
rpm_suspend() - if it succeeds to idle the device. In that case, it
tags on the RPM_AUTO flag in the call to rpm_suspend(). Quite similar
to what is happening when calling pm_runtime_put_autosuspend().

As stated above, this is already the case.

Right.

For almost everybody, except for a small bunch of drivers that
actually have a .runtime_idle() callback, pm_runtime_put() is
literally equivalent to pm_runtime_put_autosuspend().

So really the question is why anyone who doesn't provide a
.runtime_idle() callback bothers with using this special
pm_runtime_put_autosuspend() thing, which really means "do a
runtime_put(), but skip my .runtime_idle() callback".

What really is needed appears to be a combination of
pm_runtime_mark_last_busy() with pm_runtime_put().

Granted, pm_runtime_put() could do the pm_runtime_mark_last_busy()
thing automatically if autosuspend is enabled and the only consequence
of it might be delaying a suspend of the device until its autosuspend
timer expires, which should not be a problem in the vast majority of
cases.

Because they are following the documentation? It says:

"Drivers should call pm_runtime_mark_last_busy() to update this field
after carrying out I/O, typically just before calling
pm_runtime_put_autosuspend()."

and

"In order to use autosuspend, subsystems or drivers must call
pm_runtime_use_autosuspend() (...), and thereafter they should use the
various `*_autosuspend()` helper functions instead of the non#
autosuspend counterparts"

So the documentation says I should be using pm_runtime_put_autosuspend()
instead of pm_runtime_put().

Seems unfair to criticise people for following the documentation.

I'm not criticising anyone, just wondering why they do what they do.

"Because it is documented this way" is a fair answer, but it doesn't
invalidate the observation that the difference between
pm_runtime_put_autosuspend() and pm_runtime_put() boils down to the
cases when the .runtime_idle() callback is present (which are few and
far between so to speak).  Moreover, there are call sites using
pm_runtime_*() functions even though they may not know whether or not
autosuspend is enabled for the target devices, so the advice given in
the documentation cannot be universally followed regardless.

This thread is about the way to go, generally speaking, and what I'm
saying is effectively that replacing pm_runtime_put_autosuspend() with
pm_runtime_put() almost everywhere (if not just everywhere) would be
fine with me.

I also think that the current users of pm_runtime_put_autosuspend()
that is not immediately preceded by pm_runtime_mark_last_busy() can be
readily switched over to using pm_runtime_put() instead of it and then
pm_runtime_put_autosuspend() can be made call
pm_runtime_mark_last_busy(), so the latter can be removed from the
code using the former.  Note that this last step does not require
tree-wide changes, because calling pm_runtime_mark_last_busy() twice
in a row for the same device is not a problem.

Of course, the documentation needs to be updated in accordance with
the code changes, which didn't happen when previous changes were made
to pm_runtime_put() and that likely is why it does not reflect the
current code.

My guess is that it's in most cases a legacy pattern that is being
followed. Also note that rpm_idle() didn't "always" tag on the
RPM_AUTO flag, even if it's quite a while ago (2013) since we added
it.

Unless there is some actual optimization involved, as it also allows
us to skip calling rpm_idle() and go directly for rpm_suspend().

This makes sense to me too, but I don't think we should limit it to this.

Making pm_runtime_put_autosuspend (or if the name
"pm_runtime_put_suspend" is better?) to do the similar thing, is
probably a good idea too. At least in my opinion.

Right.

I guess we should expect the *sync* variants to be used, if the timer
really needs to be overridden.

Kind regards

That said, it is likely better to avoid surprising the current users
of pm_runtime_put() and define something like

static inline void pm_runtime_touch_and_put(struct device *dev)
{
        pm_runtime_mark_last_busy(dev);
        pm_runtime_put(dev);
}
