. Numerous little fixes and additional work against additional patches.
. Waaay too many "cleanups". These are taking significant amounts of
effort and it is time to start learning to live with dirty code.
. -mm kernels will be running at HZ=100 for a while. This is because
the anticipatory scheduler's behaviour may be altered by the lower
resolution. Some architectures continue to use 100Hz and we need the
testing coverage which x86 provides.

Is that usb-storage? There seem to have been a few reports of
erratic behaviour lately.

Indeed. Lots of the noise is from me :) You CC'ed Matthew Dharm on a

Testing it right now... It compiles nicely with gcc 3.3 (remember the
problems I had with snd-ymfpci when using gcc 3.2), boots and seems
functional.

There's multiple gendisks with the same .devfs_name in scsi and we call
devfs_mk_dir on each of them. I think the right fix is to let
devfs_mk_dir succeed on an existing directory.

Xfree86 4.3.0 won't start on this one. -mm4 started fine.
X will stop (and seemingly hang) on PCI initialization and iteration stage.

I'd say this is the source of this. Some cleanup along pci_for_each_dev
removal. All the 'fixes' (into while) don't even compile warningless.

I shall forward this along to Matthew, but there is not a lot of point in
working against the -mm version of this driver: it is just there for people
to test.

The interactivity seems to have dropped. Again, with common desktop
applications: xmms playing with ALSA, when choosing navigating through
evolution options or browsing with opera, music skipps.
X is running with nice -10, but with mm5 it ran smoothly.

If you don't nice the hell out of X, does it work OK?

[alistair] 07:02 PM [~] uname -r
2.5.70-mm6
For what it's worth, I'm running an LFS base system with very few packages
installed over the top. X is as packaged, it is not reniced. I am, however,
running setiathome constantly in the background, which seems to pound the
scheduler.
As Maciej reported, this seems to be significantly better with -mm5 (HZ =
1000?). Amusingly, doing a renice -20 `pidof xmms` seems to make absolutely
no difference to the scheduler in 2.5-mm.
This kernel does not have preempt enabled.
Cheers,
Alistair.
> If you don't nice the hell out of X, does it work OK?
No.
The way I reproduce the sound skips:
run xmms, run evolution, compose a mail with gpg.
on mm6 the gpg part stops the sound for a few seconds. (with X -10 and 0)
on mm5 xmms plays without stops. (with X -10)

Maciej

Sadly, I must agree with you... Sound with XMMS and Mplayer is chunky
when switching between virtual desktops, or even dragging windows. Is
this caused by latest scheduler patches, or has something to with
HZ=100?

I can't appreciate much different. I've assigned shortcuts to switch
between desktops easily. Switching between desktops very fast causes
XMMS to skip sound. This also happens when dragging windows.

I see that idle() is called much less often than before (1000
calls/second down to 150 calls/second, estimated and non-scientifical).
non-linear scale down is most probably because processes get more done
and don't wait so much.
idle() is also get called more when there is some load.
There is something weird though, I have this constant 0.8 load which I
can't pinpoint, in -mm4 fully idle machine was at about 0.1 load.
Regarding my stupidly reported Xfree86 -problem, it was PEBKAC, though I
can't tell what exactly that was. Only one module changed way to iterate
pci_find_device between boots.

I can confirm that 2.5.70-mm6 with Ingo's patch and HZ set back to 1000
is nearly perfect (it still takes some seconds for the scheduler to
adjust dynamic priorities).

OK ... sorry to be pedantic, but I want to nail this down.
It's still broken with HZ=1000, but without Ingo's patch, right?

I have to try that combination... Please, allow for a few hours and I'll

Under "heavy" disk usage (when sylpheed finish merging the lkml
messages in the 92M lkml mail folder) X pointer stops moving
(say, 1/8 or 1/6 seconds, very noticeable, pointer stops, windows stop
redrawing, etc).
System is a dual p3 800; fs is ext3. This odd behaviour
seems to happen since the 2.5.69-mm9 ext3 locking changes.
(well i started testing 2.5.70-mm3 because i'm timid,
but never happened before in mm or mainline)
Sorry that i can't provide really useful information now ;(

I've noticed similar. Just a new vague jerkiness.

Might be. There were some CPU scheduler changes a week before 2.5.69-mm9.
If it's in ext3 then profiling will probably shake it out. I haven't done
a lot of profiling yet.

Mike, any chance you can turn your series of patches into one that
applies atop mingo's intra-timeslice priority preemption patch? If
not, I suppose someone else could.
There also appears to be some kind of issue with using monotonic_clock()
with timer_pit as well as some locking overhead concerns. Something
should probably be done about those things before trying to merge the
fine-grained time accounting patch.

Well, Ingo's patch makes XMMS more resistant to audio skip when HZ=1000.
Anyways, with HZ=1000 interactivity is much better than with HZ=100
(with or without Ingo's patch).

I've never seen it. Is this the test-starve fix I heard mentioned on lkml
once?

Ingo had me measure impact with lat_ctx, and it wasn't very encouraging
(and my box is UP). I'm not sure that I wasn't seeing some cache effects
though, because the numbers jumped around quite a bit. Per Ingo, the
sequence lock change will greatly improve scalability. Doing anything
extra in that path is going to cost some pain though, so I'm trying to
figure out a way to do something ~similar. (ala perfect is the enemy of
good mantra).
wrt pit, yeah, that diff won't work if you don't have a tsc. If something
like it were used, it'd have to have ifdefs to continue using
jiffies. (the other option being only presentable on April 1:)

The issue is the driver returning garbage; not having as good of
precision from hardware is no fault of the method. I'd say timer_pit
should just return jiffies converted to nanoseconds.
Also, I posted the "thud" fix earlier in this thread in addition to the
monotonic_clock() bits. AFAICT it mitigates (or perhaps even fixes) an
infinite priority escalation scenario.

If it's used, seems some work will be required to measure the true (and
practical) impact.

That's an unearned criticism.
Timeslice management is currently an approximation. IFF the approximation
is good enough, it will/must out perform pedantic bean-counting. Current
timeslice management apparently isn't quite good enough, so I'm trying to
find a way to increase it's informational content without the (in general
case useless) overhead of attempted perfection. I'm failing miserably btw ;-)

That's the option that I figured was April 1 material, because of the
missing precision. If it could be made (somehow that I don't understand)
to produce a reasonable approximation of a high resolution clock, sure.

(yes, mitigates... maybe cures with round down, not really sure)
Couple that change with reintroduction of backboost to offset some of it's
other effects and a serious reduction of CHILD_PENALTY and you'll have a
very snappy desktop. However, there is another side of the
equation. Large instantaneous variance in sleep_avg/prio also enables the
scheduler to react quickly such that tasks which were delayed for whatever
reason rapidly get a chance collect their ticks and catch up. It can and
does cause perceived unfairness... which is in reality quite fair. It's
horrible for short period concurrency, but great for long period
throughput. AFAIKT, it's a hard problem.

The criticism was of the maxim invoked, not the specific direction
you're hacking in.

If there's a TSC, it can be used for extra interpolation. But I think
timer_tsc already does that. I don't think it's quite so laughable; the
machines missing reliable time sources are truly crippled in some way,
by obsolescence or misdesign. I wouldn't call this a deficit. The
major platforms will do fine, and the rest will do no worse than now
apart from perhaps some function call and arithmetic overhead.

I don't know that there are answers better than mitigation.
I propose we err on the other side of the fence and back off as cases
where the larger instantaneous variances are more clearly needed arise.

I run 50 fsx tests on ext3 filesystem on 2.5.70-mm6 kernel. Serveral fsx
tests hang with the status D, after the tests run for a while. No oops,
no error messages. I found same problem on mm5, but 2.5.70 is fine.

Thanks for this.
Everything is waiting on I/O. It looks like either the device driver
failed or the IO scheduler got its state all screwed up.
Which device driver are you using there?
If you could, please retest with "elevator=deadline"?

Sure.
And I saw sysrq on 2.5.70-mm6 failed on my test machine, 2.5.70-mm5
works. I could trigger sysrq by send"t", but the stack info for all
threads are the same ---the stack info of the sysrq itself.

Sorry, the tests in 2.5.70 also failed, same problem.

Thanks for your feedback.
This time I got more fsx tests hang(about 25). Before normally I saw 5
or 10 tests fail. Here is the stack info.

OK. It would be useful to test ext2 as well.

Everything stuck waiting for IO to complete again.
Are you able to try a different qlogic driver? Or a different HBA?
I tried to reproduce this but I don't have sufficient info.
How much memory does that machine have, and what fsx-linux command lines
are you using?
Thanks.

The tests were run on 8 way PIII 700MHZ, with 4G memory. The fsx
command line is:
/root/fsx -R -W -r 4096 -w 4096 /mnt/mntxx/foo &
Thanks for looking at this.
