- nicksched is still here.  There has been very little feedback, except that
  it seems to slow some workloads on NUMA.

- Added a __must_check to the x86 copy_*_user functions.  This means that
  with a sufficiently recent gcc, all unchecked copy_*_user() calls will
  generate a warning.

  I fixed a few things, but binfmt_elf.c is a mess.

  It's not clear how to apply the same debug check to put_user() and
  friends.

That's because most people aren't interested in a new cpu scheduler for
2.6. The current one works well enough in most situations and people
aren't trying -mm to fix their interactive problems since they are few
and far between. The only reports about adverse behaviour with 2.6 we 
track down to "It behaves differently to what I expect" or applications 
with no (b)locking between threads suck under load. Personally I think 
the latter is a good thing as it encourages better coding, and the 
former is something we'll have with any alternate design.

The only feedback we got on staircase was that it helped NUMA somewhat 
and Nick and Ingo made some criticisms (not counting any benchmarks I 
had to offer). The only feedback on nickshed was that it hurt NUMA 
somewhat, SMT interactivity was broken (an easy enough oversight), and I 
did not comment to avoid giving biased criticism.

If you're after subjective performance feedback you're less likely to 
get it now than ever since you've made a strong stance against 
subjective reports, due to placebo effect. LKML is scary enough for the 
average user already. We have a situation now that if one brave single 
user reports good or bad behaviour everyone runs off that one user's 
report. Ouch!

There isn't going to be a 2.7 any time soon and there are people that 
are using alternate schedulers already in production; which is obviously 
why you're giving them a test run in -mm. Clearly the lack of a formal 
(2.7) development branch makes this even harder. Your attempt at 
preventing "good stuff' from rotting in alternate trees when mainline 
should be benefitting is admirable. While it's fun to rewrite the 
scheduler and gives us something to play with, the current level of 
feedback is hardly the testbase off which to replace it unless there's 
something strikingly better about a new cpu scheduler.

It will be interesting to see if this spawns any further discussion or 
whether Peter's scheduler's performance will also be lost in a low 
signal to noise ratio when it gets a run in -mm.

Cheers,
Con

I take it that was why changing consoles between mutt and slrn would
include a pause of several seconds on a system with a single,
hyperthreaded cpu?

Is that fixed in 2.6.9-rc1-mm1?

Actually, with the current scheduler, updatedb really sucks.  It's supposed to 
be a background task, but it hogs IO resources and memory like crazy 
(disclaimer: it's my personal subjective observation).

Frankly, if I had any useful benchmark, I would have readily run it and posted 
the results.  The problem is that I don't know what kind of results you are 
interested in.  Please let me know what _exactly_ you want to measure.  
Please propose some benchmarks or post a HOWTO, or what.  "Help me help you".

I think the problem is that relatively not so many people run -mm, and even 
less people try to use them for a longer time.  Also, there sometimes are 
some issues with -mm that must be sorted out first, but then there's not much 
time left for testing the scheduler before the next -mm.

I think this is the main reason of existence for -mm kernels: find problems, 
sort them out and fix them. I've been running -mm kernels since 2.5.80+ and 
all problems I have had were resolved in a timely manner.

What I think is that Con's scheduler is the one that needs to get into -mm 
kernels to give it more exposure. Currently, it has a very limited audience.

That's the point.  You don't pay attention to the differences between 
schedulers if there are more serious problems, do you?

I agree, but it's a different thing. :-)

IMHO, -mm could stick for a while with one of the alternative schedulers so 
that it gets more testing.

That's because there are none for interactivity; you're simply 
reinforcing my point.

The cpu scheduler plays almost no part in this. It's the I/O scheduler 
and the vm. IOnice will help the former _when it comes out_. Dropping 
the swappiness kind of helps the latter; although there are numerous 
alternative tweaks appearing for that too.

Hm, can you tell me please what you consider as the most obvious interactivity 
issue that you expect to be improved by your scheduler?  A typical scenario 
in which the "standard" one will be "not good enough" in your opinion?

I know that.  It does not hurt me that much. :-)  Still, on a dual-Opteron box 
with a gig of RAM I would expect it to "behave" a bit better in the default

Rick's schedstats stuff had some ways to measure latency that seemed to work
quite nicely. Hard to simulate exactly mozilla, email, etc, but probably
close enough to be far more use than "ooh, it feels faster".

He did a whole paper at OLS ... Rick ... pointer?

It has the problem that I have reported for 2.6.8.1-mm4, that after issuing:

# rmmod snd_seq_oss

the kernel goes into a strange state:
- one CPU (either CPU0 or CPU1) is 100% loaded with system load
- the other CPU is free
- the process "rmmod snd_seq_oss" is in the D+ state
- when I exit KDE session the system hangs solid (no way to get to it, reset 
necessary).
- when I try this from a virtual terminal, it freezes the keyboard and I can't 
get to the other virtual terminals/X, but I can get to the system via ssh.

No Oops is reported, and it does not happen on 2.6.8.1-mm2.

If you're talking about using the embedded image viewer in kde, that 
spins on wait and wastes truckloads of cpu (a perfect example of poor 
coding). Try loading it an external viewer and it will be 1000 times 
faster. If you're talking about it keeping the disk too busy on the 
other hand, that's I/O scheduling.

 I've today returned from -mm series to 2.6.9-rc1 and noticed some
changes. Usual workload of my celeron 366 consist of bunch of
transparent Eterms, firefox, xmms playing and some background daemons
(like spamassassin).

 Xmms is known for unpleasant behaviour - it sleeps a lot, slowing down
entire system. This isn't noticable in top, which show ~10% CPU
dedicated to xmms, but it very easy to feel.

 Nick scheduler in contrast to stock scheduler from -linus make
interativity a lot better. When switching workspaces, windows redraw
almost instantly (max 2 seconds), whereas in -linus I often have to wait
up to 8-10 seconds to work.

 when running -mm, playing xmms don't slow thinhs much. Kernel compile
is almost as fast, as when xmms is shut. In -linus in turn, playing xmms
can slow down compile twice.

 Firefox loading 3-4 pages in tabs in -linus makes all desktop lagging.
Scheduler from -mm makes load caused by firefox unnoticabled in other
apps.

 That are my observations. It's nothing scientific and there are no
solind numbers from benchmarks to support them.

It does not hang the system, only it's dependant tasks (ie other kde

It is supposed to be "as simple as possible and no simpler" approach to
the 2 array scheduler.

The current one has a lot of 'unfairness' and temporal dependencies. Eg,
"if a process has been in an interruptible sleep and woken from interrupt,
and has been previously marked as 'interactive' then blah. If it has been
in an uninterruptible sleep then do something completely different"
(I just made that up)

So, some people's watchdog process that is using *no* CPU get 50 second
latencies. And you get unfairness problems where one CPU hog is given twice
the amount of CPU time as another because it got marked as interactive long
ago.

Basically, the only inputs into nicksched are when a process sleeps and
when it runs. The only per-process state is basically how much it runs and
how much it sleeps. Everyone is treated the same.

The kernbench regression is something I don't take lightly though. I'll see
if I can get to the bottom of it.

2.6.8.1, for example.  I'd like to compate it with the 2.6.9-rc1-mm1, which 
contains the Nick's scheduler (2.6.9-rc1 has the same scheduler as 2.6.8.1, 
AFAIK).

With these two things in hand, you should be able to measure the latency
on 2.6.8.1 of a particular process.

A patch is not necessary for 2.6.9-rc1-mm1 (schedstats is already in there)
but you will need to config the kernel to use it.  Then retrieve a slightly
different latency.c:
    
    http://eaglet.rain.com/rick/linux/schedstat/v10/latency.c

since 2.6.9-rc1-mm1 output format is different (as you noted, it's a
different scheduler.)  Then you should be able to see if the latency of
a particular process (updatedb, for instance) changes.

Thanks a lot Rick, I'll give it a try tomorrow.

My previous post details the problem with KDE I had on 2.6.9-rc1, 
2.6.9-rc1-mm1 fixed that.
I get hangs with 2.6.9-rc1-mm1 if ACPI or APM are enabled. I haven't 
tried console=ttyS1 to see if there is an oops, but from previous 
experiences also posted, they are probably being generated.
One other problem is that trying to rebuild a 2.6.9-rc1-mm1 kernel under 
2.6.9-rc1-mm1 fails, once as shown below and once elsewhere in fs/. I 
have to boot 2.6.8-rc4-mm1 in order to build 2.6.9-rc1-mm1. Asus A7N8X-E 
nForce2 chipset, Version: ASUS A7N8X-E Deluxe ACPI BIOS Rev 1011, SuSE 
9.1. Upgrading to 1012 shortly.

I don't know.

You probably want the patch I posted yesterday in "data loss" thread
(expect we'll end up choosing a competing patch, but this does fine).

It seems that after applying it one has to apply the two attached patches to 
the kernel to get it compile on a UP system.

Yes, that's correct.  Thanks; I've updated the patch.
