I still cannot get the network up and running with this. The BUG messages
are gone but the system stops processing init scripts somewhere in the
network related scripts. One time, it stopped in portmapper, the next it
got past that and stopped in the imapd script.

What I see on the screen is the normal boot, a few latency trace outputs
indicating increasing latency (up to about 2.3 msec) and then I make it to
single user mode. You can see those traces in /var/log/messages; I will
send that separately.

By doing the scripts in
  /etc/rc3.d/
by hand or by using
  telinit 3
I get normal displays until the system stops running the scripts. It just
stops at that point. No response to Ctrl-C (if done by hand). Alt-SysRq
keyboard commands do work (displayed on the screen) but the output does
not make it to /var/log/messages. The output from the second run is
particularly disappointing, it appears to be truncated.

I will rebuild with -U5 since I noticed it is available, but if you
have some suggestions on a way to capture more helpful data, I would
be glad to do it.

-U5 has CONFIG_RWSEM_DEADLOCK_DETECT, which could help with your network

I would have to say this is "very rough" at this point. I had the following
problems in the build:
 [1] kernel/ksyms.c - undefined symbols
 [2] kernel/mutex.c - obvious cut / paste problems
 [3] XFS has incompatible mutex definition
 [4] suspicious warnings
 [5] missing symbols for modules
Details at the end.

I booted w/ SMP and the machine threw a lot of error messages about
sleeping in
an invalid context. For example:

If the machine managed to record some good data in /var/log/messages
I will send them separately to you for reference.

CONFIG_PREEMPT_REALTIME is still an experimental feature and defaults to
'n'.

-T5 will likely not fix the exit.c warnings, which, unless they are
accompanied by real crashes, should be mostly harmless. (famous last
words.) (The zombie task and self-reaping thread handling is a really
hard nut to crack, and i have nobody but me to blame for that code ...)

[Ingo Molnar]

i've uploaded -T6:

  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-T6

this should fix the UP build issues reported by many. -T6 also brings
back the ->break_lock framework and converts a few more locks to raw.

SMP is still expected to be flaky due to the zombie-task problem(s). But
UP is not out of the 'extremely experimental' status either.

i've uploaded -T7:

  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-T7

Changes since -T6:

- further stabilization of PREEMPT_REALTIME: fixed the task-reaping
  problem by moving TASK_ZOMBIE out of p->state and thus completely
  separating preemption from the child-exit mechanism. This got rid of 
  the 'Badness in exit.c' warnings on my SMP testbox (and related
  crashes).

- fixed the _mutex_trylock_bh missing symbol problem reported by K.R. 
  Foley and Florian Schmidt.

- turned the sysrq lock into a raw spinlock, to enable direct keyboard
  irqs.

PREEMPT_REALTIME is still experimental, but it's already looking much
better on my testboxes.

i've uploaded the -T8 VP patch:

  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-T8

lots of stabilization of CONFIG_PREEMPT_REALTIME. It's still in
experimental status but general stability is improving.

Changes since -T7:

 - fixed a nasty category of bugs that were introduced by the use of 
   rwsems for rwlocks. rwsems are not read-recursive, while rwlocks are. 
   Fortunately it was not too hard to identify & fix recursive users of
   tasklist_lock, in fact each of these also qualifies as a cleanup. The 
   symptom of this bug was a soft-deadlocking of the system. 

 - fixed profiler locks, i believe this could resolve the bootup crash
   reported by K.R. Foley.

 - fixed VP / XFS namespace collision reported by Mark H. Johnson

 - fix one more final detail of the new zombie-task handling code

 - fixed 3c59x.c, fasync-handling, ipv6, module-loader runtime
   warnings reported by K.R. Foley.

 - fixed the ali5451 locking

[patch] Real-Time Preemption, -VP-2.6.9-rc4-mm1-U0

[Ingo Molnar]

i'm pleased to announce a significantly improved version of the
Real-Time Preemption (PREEMPT_REALTIME) feature that i have been working
towards in the past couple of weeks.

the patch (against 2.6.9-rc4-mm1) can be downloaded from:

  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-U0

this is i believe the first correct conversion of the Linux kernel to a
fully preemptible (fully mutex-based) preemption model, while still
keeping all locking properties of Linux.

I also think that this feature can and should be integrated into the
upstream kernel sometime in the future. It will need improvements and
fixes and lots of testing, but i believe the basic concept is sound and
inclusion is manageable and desirable. So comments, testing and feedback
is more than welcome!

to recap the conceptual issues that needed solving: the previous patch
already converted a fair portion of spinlocks to mutexes, but that in a
fully preemptible kernel model the following locking primitives are
especially problematic:

	- RCU locking
	- per-cpu counters and per-cpu variables
	- tlb gather/release logic
	- seqlocks
	- atomic-kmaps
	- pte mapping

note that while we tend to think about these as SMP locking primitives,
in a fully preemptible model these locking rules are necessary for
correctness, even on a single-CPU embedded box.

Unfortunately none of the existing preemption patches solve these
problems: they concentrate on UP but these locking rules must not be
ignored on UP either!

(Bill Huey's mutex patch he just released is the one notable exception i
know about, which is also a correct implementation i believe, but it
doesnt attack these locking rules [yet]. Bill's locking hierarchy is i
believe quite similar to the -T9 patch - this i believe is roughly the
best one can get when only using spinlocks as a vehicle.)

In the previous (-T9) version of the Real-Time Preemption patch, the
above locking primitives kept large portions of kernel code
non-preemptable, causing a 'spreadout' of raw spinlocks and
non-preemptible sections to various kernel subsystems.

Another, even more problematic effect was that both network drivers and
block IO drivers got 'contaminated' by raw spinlocks, triggering lots of
per-driver changes and thus limiting testability. It is basically an
opt-in model to correctness which is bad from a maintainance and
upstream acceptance point of view. The -T9 patch was a prime example of
the problems the Linux locking primitives cause in a fully preemptible
kernel model.


To solve all these fundamental problems, i improved/fixed/changed all of
these locking methods to be preemption-friendly. Most of the time it was
necessary to introduce an additional API variant because e.g.
rcu_read_lock() is anonymous (it doesnt identify the data protected), so
i introduced a variant that takes the write-lock as an argument. In the
PREEMPT_REALTIME case we can thus properly serialize on that lock.

For per-cpu variables i introduced a new API variant that creates a
spinlock-array for the per-cpu-variable, and users must make sure the
cpu field doesnt change. Migration to another CPU can happen within the
critical section, but 'statistically' the variable is still per-CPU and
update correctness is fully preserved.

TLB shootdown was the source of another nasty type of critical section:
it keeps preemption disabled during much of the pagetable zapping and
also relies on a per-CPU variable to keep TLB state. The fix for
PREEMPT_REALTIME (on x86) was to implement a simpler but preemptible TLB
flushing method. This necessiated two minor API changes to the generic
TLB shootdown code - pretty straightforward ones.

Atomic kmaps were another source of non-preemptible sections:
pte_map/pte_unmap both used nontrivial functions within and ran for a
long time, creating a lock dependency and a latency problem as well. I
wrapped them via normal kmaps, which thus become preemptible. (The main
reason for atomic kmaps were non-preemptability constraints - but those
are not present in a fully preemptible model.)

seqlocks (used within the VFS and other places) were another problem:
the are now preemptible by default, the same auto-type-detection logic
applies to them as to preemptible/raw spinlocks: switching between a
preemptible and a non-preemptible type is done by changing the
prototype, the locking APIs stay the same.

The improvements to locking allowed the gradual 'pulling out' of all
raw-spinlocks from various kernel subsystems. In the -U0 patch i have
almost completely finished this 'pullout', and as a result the following
kernel subsystems are now completely spinlock-free and 100% mutex-based:

	- networking
	- IO subsystem
	- VFS and lowlevel filesystems
	- memory management (except the SLAB allocator lock)
	- signal code
	- all of drivers/* and sound/*

note: it is important that when PREEMPT_REALTIME is disabled, the old
locking rules apply and there is no performance impact whatsoever. So
what this implements is in essence a compile-time multi-tier locking
architecture enabling 4 types of preemption models:

  - stock                      (casual voluntary kernel preemption)
  - CONFIG_PREEMPT_VOLUNTARY   (lots of cond_resched() points)
  - CONFIG_PREEMPT             (involuntary preemption plus spinlocks)
  - CONFIG_PREEMPT_REALTIME    (everything is a mutex)

these models cover all the variants people are interested in: servers
with almost no latency worries, desktops with ~1msec needs and hard-RT
applications needing both microsecond-range latencies and provable
maximum latencies.

to quantitatively see the effects of these changes to the locking
landscape, here's the output of a script that disassembles the kernel
image and counts the number of actual spin lock/unlock function calls
done versus mutex lock/unlocks:

With PREEMPT_REALTIME disabled, all locks are spinlocks and old
semaphores:

        spinlock API calls:      5359  (71.6%)
        | old mutex API calls:   2120  (28.3%)
        | new mutex API calls:      2  (0%)
        all mutex API calls:     2122  (28.3%)
        --------------------------------------
        lock API calls:          7481 (100.0%)

with the -T9 kernel, which had the 'spread out' locking model, a
considerable portion of spinlocks were replaced by mutexes, but more
than 20% of usage was still spinlocks:

        spinlock API calls:      1835  (23.1%)
        | old mutex API calls:   2142  (26.9%)
        | new mutex API calls:   3961  (49.8%)
        all mutex API calls:     6103  (76.8%)
        --------------------------------------
        lock API calls:          7938 (100.0%)

here are some fresh numbers from Bill Huey's mmLinux kernel:

        spinlock API calls:      2452  (30.3%)
        all mutex API calls:     5614  (69.6%)
        --------------------------------------
        lock API calls:          8066 (100.0%)

(his mutex implementation directly falls back to up()/down() so the new
mutexes become part of the old mutexes.)

while i believe that the locking design is fundamentally incomplete in
the MontaVista kernel and thus is not directly comparable to
PREEMPT_REALTIME nor the mmLinux kernel, here are the stats from it
using a similar .config:

        spinlock API calls:      1444  (26.1%)
        | old mutex API calls:   2095  (37.9%)
        | new mutex API calls:   1981  (35.8%)
        all mutex API calls:     4076  (73.8%)
        --------------------------------------
        lock API calls:          5520 (100.0%)

(here it is visible that apparently a significant amount of [i believe
necessary] locking is missing from this kernel.)

finally, here are the stats from the new PREEMPT_REALTIME -U0 kernel:

        spinlock API calls:       491  (6.0%)
        | old mutex API calls:   2142  (26.2%)
        | new mutex API calls:   5536  (67.7%)
        all mutex API calls:     7678  (93.9%)
        --------------------------------------
        lock API calls:          8169 (100.0%)

note that almost all of the remaining spinlocks are held for a short
amount of time and have a finite maximum duration. They involve hardware
access, scheduling and interrupt handling and timers - almost all of
that code has O(1) characteristics.

what this means is that we are approaching hard-real-time domains ... 
using what is in essence the stock Linux kernel!

note that priority inheritance is still not part of this patch, but that
effort can now be centralized to the two basic Linux semaphore types,
solving the full spectrum of priority inheritance problems!

the code is still x86-only but only for practical reasons - other
architectures will be covered in the future as well.

[patch] Real-Time Preemption, -VP-2.6.9-rc4-mm1-U1

[Ingo Molnar]

i have released the -U1 PREEMPT_REALTIME patch:
 
  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-U1

this is a strict bugfixes-only release. With -U1 i cannot reproduce any
of the bugs on my testsystems anymore, but take care nevertheless, this
is still experimental code.

Changes since -U0:

 - bugfix: fixed the highmem related crash reported by Adam Heath and i 
   think this could also fix the crash reported by Mark H Johnson.

 - bugfix: fixed a number of networking related soft-lockups, caused by
   a deadlock scenarios in the ipv4, netfilter and net-xmit locking
   code. This could fix the lockup reported by Lorenzo Allegrucci.

 - bugfix: enable interrupts in the int3 handler - gdb will otherwise
   trigger a kernel debug message.

 - cleanup: reworked the RCU API wrappers, we now have the following
   variants:
 
     rcu_read_[un]lock_spin(&spinlock)
     rcu_read_[un]lock_bh_spin(&spinlock)
     rcu_read_[un]lock_sem(&semaphore)

   this change was necessary for the network locking fixes.

 - debugging helper: SysRq-T will now print the stacktrace of currently
   running tasks too. (They might be a bit unreliable occasionally but
   very useful to debug deadlocks.)

 - configurability fix: disabled the /proc/kernel/softirq_preemption and
   hardirq_preemption runtime flags (and the softirq-preempt= and
   hardirq-preempt= boot flags) if PREEMPT_REALTIME is enabled - in the
   fully preemptible model these must always be on.

there are no known bugs at this moment, so please re-report any issues 
you might still encounter.

[patch] Real-Time Preemption, -VP-2.6.9-rc4-mm1-U2

[Ingo Molnar]

i have released the -U2 PREEMPT_REALTIME patch:

  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-U2

this too is a bugfixes-only release, and it is still experimental code.

Changes since -U1:

 - bugfix: fix page_lock_anon_vma() crash reported by Adam Heath and 
   Lorenzo Allegrucci.

 - bugfix: fix selinux atomic-schedule warning messages, reported by
   Mark H Johnson.

 - bugfix: ip_tables atomic-schedule fix, fixes the messages reported by 
   Daniel Walker and K.R. Foley.

 - bugfix: fix warnings/deadlocks in inet_create(), reported by Mark H 
   Johnson.

 - bugfix: fixed a crash-in-shmfs-during-heavy-swapout bug

 - bugfix: enable preemption while doing mmdrop() in the scheduler - it 
   may schedule.

 - debugging feature: when PREEMPT_TIMING is enabled then the code also 
   keeps a trace/stack of preemption enabler EIPs. (if LATENCY_TRACE is 
   enabled as well then the parent EIP is recorded as well.) Whenever a 
   stack trace due to atomicity violations is printed, the preemption
   stack is printed as well. This makes it much easier to identify the 
   place that did the illegal preemption-disabling.

this is a buildfixes-only release, and it is still experimental code.

[patch] Real-Time Preemption, -VP-2.6.9-rc4-mm1-U4

[Ingo Molnar]

i have released the -U4 PREEMPT_REALTIME patch:

   http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-U4

this is a fixes-only release, and it is still experimental code.

Changes since -U3:

 - crash fix: fix the rtc_lock related crash reported by Bill Huey, the 
   rtc_lock is now a raw spinlock again.

 - crash fix: avoid recursion into timer code when PREEMPT_TIMING is 
   enabled.

 - crash/printout fix: revert some of selinux's locks back to raw 
   spinlocks. This could fix the problems reported by Mark H. Johnson, 
   Adam Heath.

 - build fix: fix the compilation problems reported by Lee Revell

 - debug feature: implemented 'print backtrace on all CPUs' on SMP 
   systems, SysRq+L will trigger it.

 - build cleanup: restructure the debug config options. This should 
   resolve the build problems and incompatible debug-options
   problems reported.

 - cleanup: move definitions around, turn on generic rwlocks instead of
   the x86-specific version.

i think all bugs that were reported with logs are fixed in -U4. Please
re-report any issue that might remain.

thanks - i've fixed the U4 patch too so new downloads will have the fix.

You forgot to lowercase RT and U in the EXTRAVERSION.

i changed my mind because lowercase it looks pretty ugly in uname,
appended to the already lowercase -mm string. Why does Debian need to
have it in lowercase anyway? It doesnt seem to make much sense.

It becomes part of the package version, and the package versions are
lowercase.  But I agree, it doesn't make much sense.

-RT does look better.

It's only a minor annoyance right now.  I have to edit Makefile before
starting make-kpkg, and before backing out the previous patch.  I'll file a
bug on kernel-package at some point, but it probably won't be fixed anytime
soon(debian is preparing to release soon(HAHA!)).

these are normal, they are the PREEMPT_TIMING traces which get printed
every time the kernel measures a new latency maximum. The stack dumps
are done to make it easier to identify which place too that long of a
delay and why. (if LATENCY_TRACE is enabled too then the last latency
and its trace can also be found in /proc/latency_trace.)

after bootup it makes sense to reset the maximum:

	echo 10 > /proc/sys/kernel/preempt_max_latency

because during bootup there are a number of latencies that are one-time
only.

So, I did that, and immediately started getting more stack dumps.  Are these
things that are interesting, or only informational?

they are informational, if you are evaluating latencies. Feel free to
post larger latencies. Right now the threshold for "large" depends - on
a fast box i'd say latencies above 200 usecs are worth reporting - but
any trace can be interesting. Latencies above 1000 usecs are definitely
worth seeing.

stability has the highest priority at the moment, and the other type of
non-latency stackdumps (scheduling while atomic, smp_processor_id()
warnings or outright kernel oopses) should always be reported if
possible.

Re: [patch] Real-Time Preemption, -VP-2.6.9-rc4-mm1-U4

[john cooper]

Ingo,
    In reading your -U3 patch the test below (#156)
wasn't clear to me.   It would seem in the case of
softirq_preemption, __do_softirq() should be called
to kick ksoftirqd, otherwise ___do_softirq() would
be called to exec softirqs in the immediate context.

kernel/softirq.c:

  153   asmlinkage void _do_softirq(void)
  154   {
  155           local_irq_disable();
  156           if (!softirq_preemption)
  157                   __do_softirq();
  158           else
  159                   ___do_softirq();
  160           local_irq_enable();
  161   }

the dependencies here are a bit complex due to the
various compile-time and runtime flags, and various
architecture call-ins to softirq.c.

___do_softirq() is the 'lowest level' softirq function, it
directly executes the handlers.

__do_softirq() disables bhs and calls ___do_softirq() - this
is the 'direct' softirq execution model, this function is
called by hardirq contexts and by softirqd. [btw., irqd calls
this function too which is a bit pointless.] In the indirect
execution model (SOFTIRQ_PREEMPT) this function does no softirq
execution, it only wakes up softirqd.

_do_softirq() is what is called by softirqd - dependent on the
execution model this function will either execute ___do_softirq()
[no additional locking or bh disabling] in the threaded case,
while in the direct case it will execute __do_softirq().

so the logic seems to be correct to me. (except for the minor
detail of irqd calling __do_softirq() which doesnt make much 
sense but which is harmless otherwise.)

with DEBUG_PREEMPT it is relatively safe to call ___do_softirq()
from softirqd (without doing the extra bh disabling), because
the two main rules of softirqs are still preserved:

 1) softirq execution doesnt reenter itself

 2) per-CPU assumptions safely detected

Hi,
 I have compile error when I use the make O= option: usr/initramfs_list
doesn't exist. This doesn't occur in pure 2.6.8.1 or 2.6.9-rc4 but does  
occur in 2.6.9-rc4-mm1.

Esben

Here is a fix (the build seems not to be broken with or without O=)

The above error is from -mm and not part of Ingo's patch.
The better fix is to prefix $(CONFIG_INITRAMFS_SOURCE) with $(srctree)/

Hi,

the cpu mhz issue seems to be fixed:

~$ uname -a
Linux mango.fruits.de 2.6.9-rc4-mm1-RT-U4-RT #1 Sun Oct 17 17:48:48 CEST 2004 i686 GNU/Linux
~$ cat /proc/cpuinfo |grep MHz
cpu MHz         : 1195.145
mango:/usr/src/linux-2.6.9-rc4-mm1-VP-U4# grep REALTIME .config
CONFIG_PREEMPT_REALTIME=y


Might of course be coincidence. Will report as soon as i see the 0.001 Mhz
pop up again.

I saw one of these in /var/log/syslog:

ok, does the patch below fix those messages? (gameport.c used its own,
private, incompatible prototype for i8253_lock which breaks raw spinlock
handling.)

it seems to fix it. i don't see any more messages like the reported anymore.
snd-cs46xx might have some other issues though: Upon rmmod snd-cs46xx i see:

Oct 17 19:43:04 mango kernel: Sound Fusion CS46xx 0000:00:0f.0: Device was removed without properly calling pci_disable_device(). This may need fixing.

but i should probably report that to alsa-devel instead right?
