[PATCH 0/13] Turn hrtimers into a range capable timer

[PATCH 0/13] Turn hrtimers into a range capable timer

[Arjan van de Ven]

This series is a follow-on the the nanosecond select/poll series.

The goal of this series is to introduce the capability into hrtimers to
deal with a "range" rather than a specific point in time.
(Several people discussed this recently, but we've been toying with the
concept for a while)

In addition, in the last patch of the series, the patches make select()
and poll() use these range timers with a standard "slack" that comes
from
1) a per process task_struct value
2) a "the longer the sleep the more the slack" function that Linus wrote

[PATCH 1/13] hrtimer: add abstraction functions for accessing the "expires" member

[Arjan van de Ven]

From: Arjan van de Ven <arjan@linux.intel.com>
Subject: [PATCH] hrtimer: add abstraction functions for accessing the "expires" member

In order to be able to turn hrtimers into range based, we need to provide
accessor functions for getting to the "expires" ktime_t member of the
struct hrtimer.

This patch adds a set of accessors for this purpose:
* hrtimer_set_expires
* hrtimer_set_expires_tv64
* hrtimer_add_expires
* hrtimer_add_expires_ns
* hrtimer_get_expires
* hrtimer_get_expires_tv64
* hrtimer_get_expires_ns
* hrtimer_expires_remaining
* hrtimer_start_expires

No users of these new accessors are added yet; these follow in later patches.
Hopefully this patch can even go into 2.6.27-rc so that the conversions will
not have a bottleneck in -next

[PATCH 11/13] hrtimer: turn hrtimers into range timers

[Arjan van de Ven]

From: Arjan van de Ven <arjan@linux.intel.com>
Subject: [PATCH] hrtimer: turn hrtimers into range timers

this patch turns hrtimers into range timers; they have 2 expire points
1) the soft expire point
2) the hard expire point

the kernel will do it's regular best effort attempt to get the timer run
at the hard expire point. However, if some other time fires after the soft
expire point, the kernel now has the freedom to fire this timer at this point,
and thus grouping the events and preventing a power-expensive wakeup in the
future.

Somehow the function is called softexpires, but returns the hard expire
time...

I might be missing something, but this code only looks at the leftmost
timer, and we're indexed on the hard expire time, which might be rather
far to the right of here.

This means that esp for those timers for which we can save most we're
least likely to do so because we'll plain not see them.

What you need is a data structure that supports stabbing queries on
overlapping intervals, such like a Priority Search Tree.

If I'm not mistaken, then the augmented Red-Black tree from the EEVDF
paper is identical to PST [*].

This data-structure adds a Heap property to each RB-node, allowing one
to search the tree on a different property.

So what you can do in this case, is index the RB-tree on the soft
expire, and index the heap on the hard expire.

Then you can find the leftmost hard expire by traversing the tree using
the heap property - and program the clock-event using that time.

And you can search for soft expired entries using the RB-tree like we do
now.


[*] Fabio implemented it on top of the linux RB-tree for their wf2q+
implementation that they used for their BFQ I/O scheduler:

http://feanor.sssup.it/~fabio/linux/wfq/

And I borrowed their implementation for my scheduler work:

Even better, in the implementations below, the leftmost heap propery can
be read from the root node, so if, as with the clock event, you don't
actually need the entry itself, but just the time, you can find it by
reading the heap propery of the root node.

Which saves a whole log(n) tree traversal ;-)

Same goes for reprogramming the clock event on insert and delete, just
check the root heap property for change.

for perfection we'd need that, for a simple good we don't; timers are
also performance critical so whatever we do can't be expensive in any
way... the current method isn't any more expensive.

you're missing a little detail ;)

yes we start from left to right, and we stop once we find a timer that
we can't fire anymore. The thing that you missed is that any timer
after that (even if we could fire it now) will just be fired when the
timer we stopped on fires.. so it'll still group them around those
timers that are otherwise ungroupable.

Gah, right. How about adding the following:

/*
 * The immediate goal is minimizing wakeups, not running
 * timers at the earliest interrupt after their soft expiration.
 * This allows us to avoid using a Priority Search Tree,
 * which can answer a stabbing querry for overlapping
 * intervals and instead use the simple BST we already have.
 * We don't add extra wakeups by delaying timers that are
 * right-of a not yet expired timer, because that timer will
 * have to trigger a wakeup anyway.

fair enough; I'll merge this in (I'm not going to resend the whole
series just for this redo though... maybe when there's more feedback
I'll roll it all up)

[PATCH 12/13] hrtimer: create a "timer_slack" field in the task struct

[Arjan van de Ven]

From: Arjan van de Ven <arjan@linux.intel.com>
Subject: [PATCH] hrtimer: create a "timer_slack" field in the task struct

We want to be able to control the default "rounding" that is used by
select() and poll() and friends. This is a per process property
(so that we can have a "nice" like program to start certain programs with
a looser or stricter rounding) that can be set/get via a prctl().

For this purpose, a field called "timer_slack_ns" is added to the task
struct. In addition, a field called "default_timer_slack"ns" is added
so that tasks easily can temporarily to a more/less accurate slack and then
back to the default.

The default value of the slack is set to 50 usec; this is significantly less
than 2.6.27's average select() and poll() timing error but still allows
the kernel to group timers somewhat to preserve power behavior. Applications
and admins can override this via the prctl()

Is this a good idea? IMO it should be per-syscall, not per
application. Threads would certainly like private values... and this
makes really ugly interface.

...plus it bloats task struct.

...where did the sys_indirect proposals go? We created new syscalls,
right?

IMO we should create new syscalls here, too.

Yes it would be nice to have new syscalls for this
and no, nobody and nothing would use them.

THe really big advantag of this default-from-task-struct is that you
can have a program similar to "nice" that allows you to run an existing
program at a specified granularity (say, a version of acroread that has
a really high wakeup count but you still want to save power)

It's not just new syscalls, it's a new glibc api as well at that point.

timers are slacking today, at least for select() and poll(), and are a
great deal more so than the defaults in this patchkit.

The great advantage of the prctl() approach (which is usable) over new
system calls and glibc APIs is that it will get used, because the admin
can use it just like he uses the "nice" command, on existing software.

Ok, so select()/poll() may default to non-zero slack for legacy apps.

Yes, it is a great advantage, but it feels like a hack. Maybe it is
better done with LD_PRELOAD or something?

I'd certianly want the applications to specify slack themselves in
like 10 years.

that's not working very well in general, and doesn't work across exec
etc.

We've been talking to Ulrich to figure out what the right API for this
is (eg how to extend select/poll for this) and I still plan to work on
this, but both Linus and Ulrich seem to be very ademant that it means
only few apps will use it (and I agree with that, just look at how many
apps use linux specific APIs such as sendfile(), linux AIO etc... )

LD_PRELOAD should work over exec...

Another possibility would be to declare new syscalls, and have glibc
automatically use select_slack(, foo) if GLIBC_SLACK=foo.

That's the goal.

LD_PRELOAD is not a solution.  LD_PRELOAD always has been and always
will be a hack.  You use it to work around problems or to test
something.  Nothing else.

LD_PRELOAD and other variables are ignored in security-relevant
contexts and environments are cleared in many situations.  Sure, you
could use /etc/ld.so.preload but that works around only one problem.
Furthermore, there is a significant cost associated with preloading.
There are additional files to be loaded and it disables prelinking.

The prctl() way plus a default non-zero value is the best way for
legacy apps.  And you'll hopefully get your wish that apps will take
fate into their own hand by specifying the slack themselves.  Arjan's
proposal also introduces new poll/select-like interface which take the
additional slack value (at least that's what we discussed before).

I'm strongly opposed to using LD_PRELOAD.  And I think requiring the
libc implementation of select/ poll, ... etc to wrap around the new
interfaces which take the slack and determine the slack at userlevel
(by reading some file) is too expensive.  It's one little value per
process (group) to be kept by the kernel.  That's not much.

I have not posted the code for this yet (the patch set is huge
already :0) but yes it's going to happen.
You and I do need to figure out what a sensible interface will be for
these ;-)

Well, it is not too much, but... is the cost for userspace really
significant? You'd clearly want it stored in environment, not
filesystem...

No, it's not OK.  There are enough apps which are privileged and need
to be handled this way.  Take the X server, for instance.

You cannot really use the environment for anything meaningful.
Especially for this case, you couldn't change the setting for a
running process.  What a fully-userlevel implementation would have to
do is read the value from a file and monitor the file for changes for
every new poll/select call.  That's a huge cost.

in addition, the value really is per thread, not per process, and how
do you want to do that with env. variables?

_Need_ to be handled? They are not handled that way today, and it
still seems to work ok.

(Plus X is no longer setuid on new distros...)

So -- how do you prevent user from setting excessively high slack and
interfering with ping or passwd?

Is this important enough to warrant setting for already-running
processes? I don't think so...

Re: [PATCH 12/13] hrtimer: create a "timer_slack" field in the task struct

Hi Arjan, 

Sorry for _really_ late responce.
I recently found this patch in linux-next.

In general, I like this patch.
However,

I wonder to why PR_SET_TIMERSLACK decreasing doesn't need root privilege.

example,
nice() systemcall is
  - nice increasing (pirority decreasing) doesn't need root privilege.
  - nice decreasing (priority incriasing) need root privilege.

So, I think time slack setting need similar one.
Otherwise, non-privilege user can increase power consumpsion easily by PR_SET_TIMERSLACK.

What do you think?

setting timerslack to 0 has no real negative effects on the system on
the one hand, on the other hand, it'll be multimedia apps and games who
want to do this.

Requiring this type of app to be root doesn't sound like a good idea,
especially since all you get by "cheating" is ... the exact behavior
you ask for anyway. "Increased power consumption" isn't a root
privilege, the app can consume much more power just by a "while (1);"
loop for example.

Right.

But I worry about an end user can't find a application which 
spent large power comsumption.
Many laptop users think battery life is really really important.

end user can find "while(1)" app easily by top command.
but they can't find timerslack==0 app easily.

So, I can drop my proposal. but I hope you explain your expected end user usages.

[PATCH 13/13] hrtimer: make select() and poll() use the hrtimer range feature

[Arjan van de Ven]

From: Arjan van de Ven <arjan@linux.intel.com>
Subject: [PATCH] hrtimer: make select() and poll() use the hrtimer range feature

This patch makes the select() and poll() hrtimers use the new range
feature and settings from the task struct.

In addition, this includes the estimate_accuracy() function that Linus
posted to lkml (but with a few steps added based on experiments).

Why not use a simple logarithmic decay to drive this estimate?

or just take a 0.1% of the time ;)

Linus wrote the original, who am I to argue? 
(and arguably, it doesn't really matter much, the current code is nice
and simple enough)

i've started doing some QA of this series in -tip.

it has a new -git based topic: tip/timers/range-hrtimers.

testing found this build failure:

Hi Arjen, sorry for not replying sooner.

I had half a patch to create a new "timer layer to rule them all" called 
ktimers, which took an explicit "slop" value.  Slop is the "how long before 
its worth waking the machine for this?" value, with friendly SLOP_USECS, 
SLOP_SECONDS, SLOP_DAYS etc defines.  Implemented in terms of normal and hr 
timers, which get deprecated over time.

Heuristics work for a while, but IMHO eventually this is going to have to be 
plumbed through to userspace.

Cheers,
Rusty.

yes we need to add the system calls at some point (beyond the prctl);
however both Ulrich and Linus indicated that this will be one of those
"handful of users" kind of things. IMO it needs to work well enough
without having to change the whole application stack (and with my
patches that can be done; it works well in practice)
