2.6.18-rt1

2.6.18-rt1

[Ingo Molnar]

I'm pleased to announce the 2.6.18-rt1 tree, which can be downloaded 
from the usual place:

   http://redhat.com/~mingo/realtime-preempt/

This port to the 2.6.18 codebase was very complex (given that 5 major 
features moved from -rt into 2.6.18: rtmutex, pi-futex, genirq, gtod and 
lockdep), so it took quite some time to finish, but in exchange it 
includes nice new features and also lots of bugfixes.

In particular, a nasty softirq performance bug has been fixed, which 
caused the "5x slowdown under TCP" bug reported to lkml - those TCP 
performance figures are now on par with vanilla performance.

The biggest new features are:

 - Dynticks (a tickless kernel). This is a new feature we implemented 
   ontop of hrtimers for the -hrt patchqueue and now we merged it to -rt 
   too. There's a new config option: CONFIG_NO_HZ, which if enabled, 
   produces a system with fewer timer interrupts. Currently i686 and 
   x86_64 are tested, but in general a hrtimers-ready platform needs 
   minimal changes to support dynticks too. (from Thomas Gleixner and 
   me, the x86_64 port is from Arjan van de Ven)

 - Timer expiry statistics feature from Thomas Gleixner: 
   CONFIG_TIMER_STATS. Enable/disable via "echo 1[0] > /proc/tstats", 
   display via "cat /proc/stats".

   This kernel feature tracks the starting site (and expiry function) of 
   expired timers (both timer_list timers and hrtimers), and the number 
   of times they expired. This is a nice tool for those who'd like to 
   minimize the amount of timer ticks on their battery-based systems. 
   Sample output:

 Timerstats sample period: 3.888770 s
   12,     0 swapper          hrtimer_stop_sched_tick (hrtimer_sched_tick)
   15,     1 swapper          hcd_submit_urb (rh_timer_func)
    4,   959 kedac            schedule_timeout (process_timeout)
    1,     0 swapper          page_writeback_init (wb_timer_fn)
   28,     0 swapper          hrtimer_stop_sched_tick (hrtimer_sched_tick)
   22,  2948 IRQ 4            tty_flip_buffer_push (delayed_work_timer_fn)
    3,  3100 bash             schedule_timeout (process_timeout)
    1,     1 swapper          queue_delayed_work_on (delayed_work_timer_fn)
    1,     1 swapper          queue_delayed_work_on (delayed_work_timer_fn)
    1,     1 swapper          neigh_table_init_no_netlink (neigh_periodic_timer)
    1,  2292 ip               __netdev_watchdog_up (dev_watchdog)
    1,    23 events/1         do_cache_clean (delayed_work_timer_fn)
 90 total events, 30.0 events/sec

 - There's also a new runtime-configurable kernel option under 
   /proc/sys/kernel/timeout_granularity that allows the coarser expiry 
   of timer_list timers, and hence better batching of timer expiry. 
   (hrtimers are not affected) The value of this option gives a 
   'multiplier' to the standard HZ granularity.

 - Lock validator ported to -rt: it now checks all the sleeping lock
   variants in -rt too. This helps us catch not only deadlocks but also 
   raw-lock candidates, sooner than before.

 - The latest High Resolution Timers queue from Thomas Gleixner with 
   initial support for ARM and PPC. (Kevin Hilman, Deepak Saksena, 
   Sergei Shtylyov)

 - The latest GTOD (Generic Time Of Day) queue from John Stultz,
   including NTP cleanups from Roman Zippel.

 - The latest genirq queue: more irq-chip-ization of i686 and x86_64, 
   MSI cleanups from Eric W. Biederman et al.

 - The latest preemptible-RCU queue from Paul E McKenney and Dipankar
   Sarma.

 - (assorted fixes and improvements.)

Right now i686 and x86_64 are boot-tested, and ARM is compile-tested. 
The other architectures likely wont even build yet. This being the first 
2.6.18 based release of -rt, some tester caution is called for.

to build a 2.6.18-rt1 tree, the following patches should be applied:

  http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.18.tar.bz2
  http://redhat.com/~mingo/realtime-preempt/patch-2.6.18-rt1

as usual, bugreports, fixes and suggestions are welcome,

	Ingo

I hadn't built one of these in quite a while, mainly because I could never 
get tvtime to run while booted to them, some sort of a dma related failure 
I think, so I rather dropped off the path here.

But the announcement was enough to make me try to build it, sort of the 
ultimate "can an old fart build it test", but the make exits with:

  LD      .tmp_vmlinux1
kernel/built-in.o(.text+0x16f25): In function `hrtimer_start':
: undefined reference to `hrtimer_update_timer_prio'
make: *** [.tmp_vmlinux1] Error 1

about half way thru the normal time.  config attached.  I don't think hires 
timers are enabled.

Comments?

And that one does an Opps during boot & freezes.  The first line says 
something about being unable to handle a dereference of $00000000, and 
goes on from there.  Its about 2 screens full, so I'd have to take a pix 
to get any more really accurate data.

I guess we could say the "can an old fart build it" test failed :)

OK, using that instead.

I get the following at startup, which probably means that I need to use
some machine other than a NUMA-Q.  Trying a different machine...

I get this too, it happens when HRT is off.. If you turn HRT on it will
boot .. I haven't found a fix for it, but I imagine Thomas will find it
soon.

Well, enabling HRT allowed it to boot, but there are several casualties.  

For some reason, "heyu turn a14 off" which works with non-rt kernels, seems 
to hang forever, or until its ctl-c'd.  And all my control scripts that 
use heyu fail.  I killed the background processes that my startup script 
starts, re-ran them by hand and now its working.  Shakes head in 
puzzlement...

Tvtime is still dead, sits in a blue screen & no sound.  I have a cx88 
tvaudio process running at -5 nice that I can't kill, if I do its back on 
the next htop refresh.

/usr/local/bin/upsd (the belkin supplied version) is using up to half the 
cpu.  The cpu of course is running 10F warmer.  And a SIGHUP from htop 
killed it.  And restarting it via an "sh ./S99bulldog" causes a repeat of 
its cpu hogging.

Audacity-1.2.4 takes 30 seconds to clear the busy icon when started with no 
arguments from the icon.  I don't recall observing that before, but its 
been a while since I ran it for any reason too, so my memory could be hazy 
on that.

Hot-babe, (a debian toy) when running, looks normal, but uses 20% of the 
cpu, which contributes to the strip job. :)

All in all, it could be worse.  Now I have to shut down and replace the 
ailing battery in my ups, it just walked in the door.  And that has 
nothing to do with this kernel 2.6.18-rt2.

I'm re-building with HRT on now, but I just noticed another side effect of 
2.6.18.  I have an led sniffer plugged into the pl2302 usb<->serial 
adaptor laying where I can see it, and all leds are red, as if the 
interface has not been inited properly.  And I don't see it being 
initialized in the dmesg.  I thought the default was to build it.  Yup, 
pl2303.ko is present in the /lib/modules trees all across the board.

Any ideas on this one folks?

That looks like the chorus of the song I saw when it crashed on boot, 
pretty darned close to identical.

What about the !PREEMPT_RT case.. It still wouldn't disable interrupts
in the below.. 

 
-       local_irq_save(flags);
        if (up->port.sysrq) {
                /* serial8250_handle_port() already took the lock */
                locked = 0;
        } else if (oops_in_progress) {
-               locked = spin_trylock(&up->port.lock);
+               locked = spin_trylock_irqsave(&up->port.lock, flags);
        } else
-               spin_lock(&up->port.lock);

_irqsave disables interrupts, always did.

In this case it had interrupts off in the !PREEMPT_RT case, but your
change leaves them on here.. _irqsave only runs in two of the three
cases..

in the old version interrupts are off, and stay off until the function
returns in all cases. Even "locked = 0" .

Now in the new version interrupts are only off if you _get the lock_.
Presumably the lock is taken in the calling function, but interrupts
aren't disabled. 

I'm assuming the code is disabling interrupts for a good reason, I don't
know enough about the code to say it isn't.

yeah, agreed - behavior now changed due to my patch. This is really 
twisted code...

I am seeing an intermittent lock up on the ARM Versatile board during the
ALSA driver init  that only shows up with (PREEMPT_RT & !HIGH_RES_TIMERS 
& ARM_EABI) enabled. If HRT is disabled and EABI is enabled, the kernel 
works every time, and same with !RT & !HRT & EABI.  I get no oops, just
a complete lock up with no console output.

In summary:


PREEMPT	HRT	EABI	BOOTS
------------------------------------------
2.6.18-rt3
------------------------------------------
RT	Y	Y	Y
RT	N	Y	Intermittent
RT	N	N	Y
NONE	Y	Y	Y
NONE	N	Y	Y
NONE	N	N	Y
------------------------------------------
2.6.18-vanilla
------------------------------------------
N/A		Y	Y
------------------------------------------

I need to go pinpoint the exact point where it is locking up during
the ALSA driver init (calls to udelay() seem suspect to me) and it
is very possible that this is a toolchain issue but want to see if
any other ARM folks are seeing issues with EABI & !HRT.

does enabling LOCKDEP give you any better info? (It might not make a 
difference on the bootup that locks, but maybe you'll get a lockdep clue 
about the problem in one of the successful bootups.)

This is with LOCKDEP enabled. I'll look at this more tommorrow but
I think next steps for me are printks to see if I can pinpoint the
issue and possibly looking at the assembly to see if there's an obvious
compiler issue.

This patch (queued for Linus) lifts that 4MB limitation:

	http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=3809/2

(I ran into the limit when enabling lockdep on ARM.)

A few of us hit a snag in Lennert's original patch.  He has a

The 'sub r3, r3, r5' check to determine the compressed kernel size in
arch/arm/boot/compressed/head.S doesn't work properly, since at that
point, r3 will have been overwritten by cache_on().

What we can do is to use sp instead, which does not get clobbered in
the meanwhile.  Using sp will give us a slightly higher compressed
kernel image size guess than when using r3, but that's safe.

Bug reported by John Cooper and David Anders.

my SMP systems since we went past 2.6.16.

including the rest of the boot log below in hopes that will help.
Suggestions? Something else I can provide?

I'm seeing a similar issue. Although the log is a bit futzed. Maybe its
the sd_mod?

Yes. This looks very much like the problem I am having. However, on the
system that this log came from I have no SCSI.

would be nice to figure out why it crashes - unfortunately i cannot 
trigger it. Could it be some build tool incompatibility perhaps? Some 
sizing issue (some module struct gets too large)?

Put some debugging into __find_symbol() and came up w/ this:

lookup_symbol: scsi_print_sense_hdr 0xc0385590 0xc038a514

Where it goes through that range in kernel_symbol increments.

The last one it checks before crashing is: 0xc0387a10

>From Symbol.map:
c0385590 R __start___ksymtab
c038a514 R __stop___ksymtab

That looks right. Now looking up 0xc0387a10, there's no symbol there.

c03879e8 r __ksymtab_find_next_bit
c03879f0 r __ksymtab_find_next_zero_bit
c03879f8 R __write_lock_failed
c0387a18 R __read_lock_failed
c0387a2c r __ksymtab___delay
c0387a34 r __ksymtab___const_udelay
c0387a3c r __ksymtab___udelay
c0387a44 r __ksymtab___ndelay

That __read/__write_lock_failed bit looks wrong.

That's as far as I've gotten so far, but will email with more as I find
it.

So it seems gcc 3.4.4 misplaces the __write_lock_failed function into
the ksymtab. It doesn't happen w/ 4.0.3. 

Anyway, this patch explicitly defines the section and fixes the issue
for me. Would the other reporters of this issue give it a whirl as well?

thanks

John,

This fixes my problem on my fc3 box here at home. I will check my other
development boxes at work tomorrow. Nice catch and thanks for effort.

i think it's an ld bug, and it's related to the nested 
.section/.previous use in the LOCK_PREFIX macro in 
include/asm-i386/alternatives.h.

this is the second time i have seen smp-alternatives related linker 
breakage.

Are you sure, that kernel and .config are related ?

Hi Ingo,
   I gave 2.6.18-rt2 a quick try. It compiled fine but crashed on
boot. I've no way to copy the screen. I can send along a digital photo
if the following isn't enough info.

QUESTION: Should I be able to run ati-drivers-8.28.8 with this kernel
or would I have to wait for ATI to put out a 2.6.18 compatible driver?
The current version does not emerge with 2.6.18-rt2.

CRASH INFO:

more stuff......

Not sure how much that will help you. Been awhile since I've sent
along crash reports. I'll have to ge a second Linux machine running to
do the console boot capture thing if you need it.

Hope this helps,
Mark

Hi again Ingo.
   2.6.18-rt3 booted. For some reason a number of drivers either
didn't get built or didn't get loaded. I'm looking into that now:

lightning ~ # lsmod
Module                  Size  Used by
lightning ~ #

   I am wrting you from the machine running the new kernel so we're
making headway.

   I spot this in dmesg though:

EXT3-fs: mounted filesystem with ordered data mode.
Adding 2008084k swap on /dev/sda10.  Priority:-1 extents:1 across:2008084k

Speaking of which...

This patch moves put_task_struct() reaping into a thread instead of an
RCU callback function as discussed with Esben publically and Ingo privately:

had some time to think about it since yesterday: RCU reaping is done in 
softirqs (check out the softirq-rcu threads on your -rt box), that's why 
i removed the delayed-task-drop code to begin with. Now i dont doubt 
that you saw crashes under 2.6.17 - but did you manage to figure out 
what the reason is for those crashes, and do those reasons really 
necessiate the pushing of task-reapdown into yet another set of kernel 
threads?

It's correct from the standpoint of it being reaped in another thread,
so it fixed those crashes. But I pushed it down into another thread at the
request of Esben and his private discussion with Paul McKenney, since
a summary from Esben felt that call_rcu() was somehow less than ideal to
do that.

Unfortunately no. I even used Robert's .config on my machine. I added a
disk controller and networking device driver just to boot into his
configuration and I still couldn't replicated any of his kjournald problems
at all. If I had his hardware I'd have a better way of replicating those
problems and pound it out.

but it _is_ already being reaped in another thread: softirq-rcu. 
Splitting that up any further will only fragment the context-switching 
and increases cache footprint - it wont (or rather, shouldnt) have any 
functional effect. (As a sidenote, i'm considering the unification of 
all 'same default priority' softirq threads into a single thread per 
CPU, to further reduce this cost of 'spreadout'.)

ok, then i guess what we have left is to wait and see whether it still 
triggers with the current 2.6.18-rt codebase - maybe it triggers for 
someone in a scenario that is easier to debug.

I overloaded another reaping thread that was doing largely similar
functionality in that it was also reaping, so I don't think it's that bad.
I did it from a cleanliness point of view with the code tree. It's the
"desched_thread" in fork.c that I'm using. It seems to be the right
thing to do. I'm sure Esben will follow up on this.

the reason why i added desched_thread was not because it's "more right" 
to do this from a separate context, but simply because the resource 
freed by it is not being freed via RCU by the upstream kernel. If that 
resource (mm_struct) were freed by RCU we'd have its rt-friendly 
reapdown "for free" and no desched_thread would be needed at all.

I only did that because I saw it there and I assumed it the was the correct
thing to use and that's why I used it.

Well, it's difficult to say. I can't say which is the best method. If the
upstream kernel used RCU function in a task allocation or task struct reading
in the first place then call_rcu() would be a clear choice. However, I didn't
see it used in that way (I could be wrong) so I use the next closest thing that
seems reasonable which is the thread desched_thread(). It use it to avoid
overloading the sematics of call_rcu() to be anything other than a pure RCU
callback. I suggest talking to Esben an Paul about this to get their view on
the matter.

Either method, call_rcu or desched_thread does the trick outside of the
scheduler path and fixes the problem. It's your choice.

Unfortunately, this is a problem with -rt patch and the lock ordering
in this system when you have to call a memory allocator within an atomic
critical section. I fully accept this as part of what goes into making a
kernel preemptive and I'm ok with it. Not many folks know about the
special case locking rules in the -rt kernel so this might be new to
various folks.

If you're looking for validation of this technique from me and an ego
stroking, then you have it from me. :)

Fortunately, it's in a non-critical place so this should *not* be too
much of a problem, but I've already encountered oddies trying to
allocate a pool of entities for populating a free list under an atomic
critical section of some sort for some code I've been writing. This is
a significant problem with kernel coding in -rt, but I can't say what
the general solution is other than making the memory allocators
non-preemptible by reverting the locks back to raw spinlocks, etc...
using lock-break, who knows. I'm ok with the current scenario, but this
could eventually be a larger problem.

The whole point is to defer those frees to a task. In -rt call_rcu() is 
abused to do that in the case of put_task_struct(). But it is abuse since 
call_rcu() is much more resourcefull than simply defering to a task.

Paul's idea behind de-RCU'ing put_task_struct() is mostly performance and 
partly readability because the extra RCU protection isn't needed.

So the answer is:
Make a general softirq to which free's can be defered from atomic regions, 
don't abuse call_rcu().

nah, it's not nearly as "resourceful" as having a separate thread for 
each teardown type ... It is also the easiest to maintain way of tearing 
down stuff, so i'm quite happy with it. If then i'll move the mm_struct 
teardown to RCU too. (Later on we can do some 'fastpath RCU' thing 
perhaps, to force an RCU batch of work through quiescent state)

but this is quite likely a side-issue that probably has no connection to 
the crash Bill was seeing. Whether separate teardown thread or 
softirq-rcu, it's a separate thread already.

Robert's stack traces looked completely wrong as well which is why I gave up.
Symbols showing up in this stack traces should have been completely compiled
out.

Also, triggering a panic() at the beginning of the rt mutex acquire was
very useful since it made "in_atomic()" violations an explicit error stopping
the machine. Stack traces started to get really crazy in this preemptive
kernel with all sorts of things running unlike the non-preemptive kernel and
it was time consuming to figure out the real stuff from the noise in the
stack trace.

It made the stack traces smaller and more immediately local to the problem
logic. Then I discovered panic() didn't work correctly in -rt so I fixed that
as well. There were a lot of little breakdowns in 2.6.17-rt...

well you should absolutely have serial console if you effectively want 
to hack the Linux kernel. And in the serial console log you should 
search for stacktraces top-down, and concentrate on the first one - any 
subsequent one might be collateral damage of the first one.

Of course I did that. I'm not that stupid. :) The stack traces, even with
your above suggestions were too many and I had to break it down a bug at
a time, stack trace at a time, since I realize problems earlier could
clash and trigger other unrelated problems.

It was even problematic with the serial console on which is why I did
that. Maybe it was an artifact of having both the serial console and video
consoles on ?

perhaps the real problem was that you got 'intermixed' stackdumps from 
multiple CPUs crashing at once? Or was it simply the myriads of 
stackdumps? The myriads effect is easy to solve: only look at the first 
one, and fix them one by one :-)

I don't think I have to tell you that things got "really weird" for a
while which is why I took the route of most severity and elected to use
extreme debugging methods. :)

I mean, some of those stack traces kept triggering a jumble of schedule()
calls, etc... I decided to hack the heads off of them one at at time and
stop the kernel immediately after one of those bugs. The immediate panic()
is what caught the tbl raw_spinlock issue and therefore my lock reversion
after auditing that portion of the lock graph.

Stupid question.

Why does the rt tree make all calls to put_task_struct an rcu action?
We only need the rcu callback from kernel/exit.c

Nothing else needs those semantics.

I agree that put_task_struct is the most common point so this is unlikely
to remove your issues with rcu callbacks but it just seems completely backwards
to increase the number of rcu callbacks in the rt tree.

It's a great question actually.

Because the conversion of memory allocation routines like kmalloc and kfree aren't
safely callable within a preempt_disable critical section since they were incompletely
converted in the -rt. It can run into the sleeping in atomic scenario which can result
in a deadlock since those routines use blocking locks internally in the implementation
now as a result of the spinlock_t conversion to blocking locks.
 
> Nothing else needs those semantics.

Right, blame it on the incomplete conversion of the kmalloc and friends. GFP_ATOMIC is
is kind of meaningless in the -rt tree and it might be a good thing to add something
like GFP_RT_ATOMIC for cases like this to be handled properly and restore that particular
semantic in a more meaningful way.

I'm not sure what mean here, but if you mean that you don't like the RCU API abuse then
I agree with you on that. However, Ingo disagrees and I'm not going to argue it with him.
Although, I'm not going stop you if you do. :)

Interesting.  I think the easy solution would just be to assert that put_task_struct
can sleep and to fix any callers that expect differently.  I haven't looked very
closely but I don't recall anything that needs put_task_struct to be atomic.
With a function that complex I certainly would not expect it to never sleep unless
it had a big fat comment.

Well I did find an instance where we call put_task_struct with a
spinlock held.  Inside of lib/rwsem.c:rwsem_down_failed_common(). 

Still that may be the only user that cares.  I suspect with a little
code rearrangement that case is fixable.  It's not like that code is a
fast path or anything.  It should just be a matter of passing the 
task struct outside of the spinlock before calling put_task_struct.

But this is a path where we are freeing data, so GFP_ATOMIC should not come
into it.  I just read through the code and there are not allocations
there.

What I was thinking is that rcu isn't terribly friendly to realtime
activities because it postpones work and can wind up with a lot of
work to do at some random time later which can be bad for latencies. 

So I was very surprised to see an rt patch making more things under
rcu protection.  Especially as I have heard other developers worried
about rt issues discussing removing the rcu functionality.

My gut feel now that I understand the pieces is that this approach has
all of the hallmarks of a hack, both the kmalloc/kfree thing and even
more calling put_task_struct in an atomic context.  If the callers
were fixed put_task_struct could safely sleep so kmalloc/kfree
sleeping would not be a problem.

One of the main claims about the -rt patch is that the kernel is basically
conversion of the current locking semantics in the kernel. What you mentioned
above would deviate from that and and clutter non-preemptive kernel maintenance.
If you're suggesting a more general change to that function, then it wouldn't
violate that.

Yeah, that's what the small patch of mine does outside of doing an RCU
callback.

Correct, I see it as a possibly bigger problem since memory allocators and
destructors aren't available readily in preempt_disable critical sections.
It's not the case in the regular kernel which could be a significant concern.

There are a couple of issues here.

(1) The RCU callback isn't used in this case to back other RCU read critical
sections. It's just used as a generic callback mechanism in this case. Some
consider it a hack.

(2) RCU isn't necessarily bad for -rt since Paul McKenney and folks are
working on making it preempt friendly. Any talk of removing the use RCU in -rt
is premature and probably unlikely because of this work. There are many options
here. RCU very useful for scalability so seeing it go away in -rt would be
generally a bad thing IMO.

The use of lock-free techinques is something that could eventually be more
widely used in -rt since it'll make kernel call paths potentially more
deterministic without worrying about hitting a contending mutex and that can
effect determinism. It's not expect to be the case where calls into the kernel
are going to be deterministic but to extend the basic idea of determinism into
certain critical kernel paths like a read() to a special device driver, etc...

Route table look up also comes to mind here that benefits from this case if
there's a need for real time facilities in networking.

Just some ideas here.

I can't say. The current logic just queues the request into a list and a
thread wakes to reap that task_struct. It's sufficient and the need to
convert put_task_struct so that it can block.

Yes I am.  The motivator would be the RT work but I don't see a reason why
the it couldn't be put in the mainline kernel.  If not at least we need
the big fat comment in the mainline kernel that says put_task_struct must
be safe to call with interrupts disabled.

The way the code is structured now it deviates from the mainline kernel in
more than just changing locking behavior.  Which is what brought me into
this conversation in the first place.  So removing that point of discord
would be good.

If you have fixed rwsem_down_failed_common() like it sounds like you have.
That would be a nice patch to for the mainline kernel.

Yes.  I would say that memory allocators have never been readily available in
sections where we have preemption disabled, but they at least are available
and sometimes they will even give you the memory you asked for.

Agreed.  However until the issues are resolved with call_rcu it appears quite
silly to increase the usage of it in the RT tree.  

About the rcu removal discussion I heard it was more the possibility was
suggested because the downside was significant, and normal locks were
more deterministic.  The emphasis was that call_rcu could be a problem and
that something needs to happen to fix that.

Agreed.  The normal rcu path is quite nice.  It is the call_rcu part used
to implement delayed freeing where things get ugly.

Yes the current logic is simple and requires no changes elsewhere.
It is always nice when you can do that.  But in this case it adds unnecessary
overhead, and indeterminism.   From what little I understand of RCU both
of those are bad things.  Thus my gut feeling that the approach is a hack
and should get fixed properly.

Anyway short of submitting a patch I think I have said enough.
Thank you for the explanation.

well, this is one of those few cases (out of ~50,000 lock uses in the 
kernel) where such a change was unavoidable: put_task_struct() is used 
in the scheduler context-switch path. (see sched.c:finish_task_switch())

So that's why i first turned it into a separate, extra delayed-free via 
the "desched thread", and later on picked up the RCUification from Paul 
McKenney. The RCUification was the simpler (and hence easier to 
maintain) change. There is no problem with putting this into the RCU 
path on PREEMPT_RT, as this is a resource-freeing act. I.e. whatever 
'delay' there might be in RCU processing, it does not impact program 
logic. I agree with you that on !PREEMPT_RT there's no reason to 
complicate things with an extra layer of indirection.

I had missed that was in a preempt disable path when I skimmed through
the users.

I'm still wondering if we can move put_task_struct a little lower in
the logic in the places where it is called, so it isn't called under a
lock, or with preemption disabled.  The only downside I see is that it
might convolute the logic into unreadability.

In general I get nervous about calling big functions while holding locks.

well it's all a function of the task reaping logic: right now we in 
essence complete the reaping from the scheduler, via prev_state == 
TASK_DEAD. We cannot do it sooner because the task is still in use. I 
had one other implementation upstream some time ago, which was a 
single-slot cache for reaped tasks - but that uglified other codepaths 
because _something_ has to notice that the task has been unscheduled.

I believe that we are way too far into the task-teardown process for
something like synchronize_rcu() to be feasible (not enough of the
task left to be able to sleep!), but thought I should bring up the
possibility on the off-chance that it caused someone to come up with a
better approach.

Another possible approach would be workqueues.  The disadvantages here are
(1) higher overhead (2) workqueues can be delayed for a -long- time in a
realtime environment, which increases vulnerability to memory exhaustion.

Again, hoping this provokes some better ideas...

RCU is really mostly used as a garbage-collection scheme, and hence its 
latency, while it can be practically problematic in some cases, never is 
directly visible in terms of application or kernel behavior.

the same is in this case: the call_rcu() use is for gathering totally 
unused task structs. There should be no side-effects.

Yes, there are few places. It was primarily to handle the reaping during the
finishing parts of a fork. All in all, it's not at all a critical path.

The problem only exists under -rt in that scheduling path. I can't comment if

In a general purpose system as complicated as Linux, "locks being more
deterministic" is kind of ridiculous. Tons of stuff can happen that you
can't control. The RCU thing that you heard was probably just ideas being
thrown around and there are many options that haven't been explored yet.
The actual scenario is more complicated than what you might have initially
heard.

The RCU callback stuff runs as a thread. The key part of a preemptible system
that can make guarantees is the ability to response to a higher priority thread
in a deterministic amount of time. That's the only real guarantee that can be
made in that system. Because of it running in a thread, callbacks in RCU don't
effect the preemptibility of the system at all.

Any kernel thread taking the risk of acquiring a lock cannot be deterministic
in any reasonable sense. Any claims of a guarantee is pretty much a lie since
the system is too complicated to analysize for determinism in any meaningful
way using the analysis techniques out there. The kernel is just too complicated.

In contrast, specialize RT apps with few threads is another scenario that's much
more controllable.

I agree. It's a hack and it should go away. You're the fourth person to mention
something about this, but it's up to Ingo.

no. It was primarily to move the put_task_struct() off the 
context-switch fastpath. (In comparison the fork use is much rarer)

Only activities with no deadlines are postponed. And therefore RCU is good 
for the latencies of the application. No high-priority, low-latency task
should bother spend time traversing and freeing a complicated datastructure.
Defer that to some lower priority task.

That put_task_struct uses RCU is a hack to defer the job to a lower 
priority task. I think the right solution is to  defer the job to a lower 
priority task using a cheaper mechanism. put_task_struct() is used from 
high priority tasks in the priority inheritance code and should only do 
the minimal job of defering the real work to another task.

they were not 'incompletely converted' - they are /intentionally/ fully

What I meant by "incompletely converted" is that the allocators could be
made more safe in non-preemptible scenarios under -rt. It's potentially
a valuable thing to have since GFP_ATOMIC semantics already exist in the
current allocators and a newer category could be added as a new feature of
that allocator for those scenarios. I'm happy dequeuing things off of my
own free list, but that's just me.

-rt semanatics created a couple of new locking scenarios that the previous
kernel didn't really have to address. That's all that I meant by that. :)

no, the -rt kernel intentionally does not do that and wont do that. 
There's lots of complex stuff going on within allocators, even in the 
GFP_ATOMIC path. We might be able to plug in more deterministic 
allocators (like SLOB), but even they must be fully preemptible. In the 
-rt kernel there's basically no compromise on the "do as little as 
possible in non-preemptible regions" stance.

Hi, i tried 2.6.18-rt3 on my athlon 1.2ghz box and it builds and boots just 
fine (tried complete preemption, hi res timers and tickless kernel). I see 
some rather strange hi-level problems though:


- I haven't built the realtime lsm yet, nor does debian have rt_limits support 
for pam (i think, and even if it does i haven't set it up as i use rt-lsm). I 
can run jackd in realtime mode without problems though. This is very strange. 
As if no capabilities checkign is done.

- I cannot log into X through gdm, as it seems that independent of what kind 
of session i select X dies right after login. I need to startx from the 
console. I wouldn't know where to look for more info on this though.

- Switching from X to another virtual console takes ca. 20 seconds in which 
nothing happens, the screen locks, but the mouse cursor is still movable, 
then finally it switches to the console allright.

.config attached

Besides these problems it ran very well for the hours i had it up. Nothing 
suspicious in the logs. Will try another build with more aggressive debugging 
options.

Flo

Erm, forget this bug report.

- The long switching to console time seems to be duee to the xorg nv driver

- logging into X via gdm now fails under different kernels, too (though i 
still have no clue why)

- also in 2.6.17-rt8  i can run jack with rt even though no rt-lsm is loaded. 
This is the only really funky one, but i suspect there's some other mechanism 
that explains this.

Regarsd,
Flo

Just curious about the cause and fix for this issue.  I tried searching
the mail lists for discussion but came up empty.  The patch it too big
for me to determine what specific changes addressed this issue.  If anyone
can point me in the right direction, that would be appreciated.

i /think/ it's this bit of code commented out in kernel/softirq.c:

        //if (!in_interrupt() && local_softirq_pending())
        //      invoke_softirq();

try to uncomment that. (this should i think do the trick on PREEMPT_RT - 
but no guarantees. It might cause problems on !PREEMPT_RT configs, i had 
to juggle around some code here. Maybe the easiest would be if you tried 
to take the new softirq.c, sans the lockdep changes. Not sure how 
feasible that is though.)

I see a very similar crash while running rcutorture on 2.6.18-mm1 and
my rcu patchset that has rcupreempt stuff rom -rt. I don't see this
while running on 2.6.18-rc3, but then rc3 had an older version
of rcutorture. I am working on narrowing it down.

The following script reproduces the problem quickly (within
a couple of minutes) in my 4-cpu x86_64 system -

#! /bin/sh
for ((i=0 ; i<200 ; i++))
do
        echo "Starting pass $i"
        modprobe rcutorture stat_interval=10 # test_no_idle_hz=1 shuffle_interval=5
        sleep 30
        rmmod rcutorture
        dmesg | sed -n -e '/^rcutorture: --- End of test:/p' | tail -1
done
exit 0

Let me know if you want more info such as config.  I was compiling a
kernel when the Oops occurred.  System is Athlon X2.

Bug just happened here on a tainted UP x86_64 running rt4.
IIRC this is the second time in 2 weeks or so.
Machine seams to be fine still after the oops...

Sorry, I should have published my investigations long ago. I tracked
this down (atleast the crash in my machine) to NMI interference
with rcu_read_lock()/rcu_read_unlock(). We use those APIs
from NMI context as well 
(default_do_nmi()->notify_die()->atomic_notifier_call_chain()).

Can you try with nmi_watchdog=0 in the kernel command line ?

Paul has an NMI-safe patch for rcupreempt which I am adopting
and testing at the moment. If this works well, I will publish
a new patchset.

Thanks

The bug is too hard to hit for me to provide useful feedback.  I've only
seen it once since my original report.

FWIW, I am also seeing hard lockups every 12-24 hours but the box is
headless and I don't have the bandwidth to debug these further.  It was
stable with 2.6.17-rt*.

Can you try whatever you were doing with nmi_watchdog=0 ? If it is
stable, then that would explain the problem. I believe Andi enabled
nmi watchdog on x86_64 by default recently, that might be why
we are seeing it now.

Looks like that was the problem, the hard lockups are gone.

ok. Meanwhile i discovered that i fixed this bug on i686 but not on 
x86_64. Could you try -rt6, does it work with the NMI watchdog 
re-enabled?

spent some good time debugging this 2 weeks ago and added the fix below 
to rt5, but i forgot to do the symmetric fix for x86_64...
