Regressions... from the context, I'm assuming you're not talking
regression errors here?  I'm assuming these are performance issues?  I
see a 3.5% drop in compiling speed between 2.4.24 and 2.6.5 on a dual
Athlon workstation.  I'll test this kernel happily if the scheduler
tweaks are intended to address this.

Hi Kurt,
The context was actually sched-domains regressions vs numasched,
which might possibly arise in any SMP (even simple dual) system.
So in this case we are interested in -mm regressions compared to
the official 2.6 tree.

2.6 regressions versus 2.4 are still interesting, but a 3.5% drop
in kernel compiling is probably due to HZ=1000 and rmap, although
I think you can expect improvements in rmap overhead soon... try
2.6.5-aa5 if you are interested.

Re: 2.6.5-mm5 devpts filesystem doesn't work

[Helge Hafting]

I tried stepping up from 2.6.5-rc3-mm4 to 2.6.5-mm4.
This Quokka seems too zonked to work though.

It came up, but I couldn't run "xterm".  Trying from
the xemacs shell I saw an error message about not enough ptys.
I use the devpts fs mounted on /dev/pts

It mounts just fine, but doesn't work apparently.  There are no
such problems with 2.6.5-rc3-mm4

Is this 2.6.5-mm4 or 2.6.5-mm5?

If the latter, try reverting pty-allocation-first-fit.patch

Also seeing this with 2.6.5-mm5, reverting pty-allocation-first-fit.patch
fixes it.

yes, that patch is bust.  And rwsem-scale.patch is oopsing all over the
place.  Ho hum.

I've trashed 2.6.5-mm5 and am uploading 2.6.5-mm5-1, same place.

where is the announce? Just wondering why at least these:

- devinet-ctl_table-fix.patch
- ipmi-socket-interface.patch

are missing?

I don't think this actually fixed anything.

It doesn't look like we're proceeding with this.

I have more results with DBT-2 on my 4-way Xeon system:
	http://developer.osdl.org/markw/fs/dbt2_project_results.html

It doesn't look like the latest cpu scheduler work is helping this
workload.  I've also made sure that the database was set to use fsync
instead of fdatasync so you can see if those fsync speedup patches are
offering anything with this workload too.

Hmm, well the sched-less-idle patch is in mm5, which brought
2.6.5-rc3-mm4 to 2320 on ext2.

The only other significant scheduler changes since that kernel
are in -mm5.
+sched_less_idle
+sched_balance_context

So either sched_balance_context is causing a regression that
counters sched_less_idle, or maybe it isn't a scheduler problem?

how stable are the results? Could the 2180 => 2165 drop be noise?

I have a result on ext2 with 2.6.6-rc1 that looks good:
	http://developer.osdl.org/markw/fs/dbt2_project_results.html

           ext2  ext3
2.6.6-rc1  2385
2.6.5-mm5  2165  1933
2.6.5-mm4  2180
2.6.5-mm3  2165  1930
2.6.5      2385

I'll run one for ext3 too.

I've found results to bt stable within a few percent, so this drop could
be noise.

OK that's weird. You got much better results with sched-less-idle
before.

Any chance you could do a run on -mm with interrupt balancing turned
on? Could you also turn CONFIG_SCHEDSTATS on (-mm only), and send
me a snapshot of /proc/schedstat before and after your run?

Thank you.

I do already have CONFIG_IRQBALANCE=y.  Is that the interrupt balancing?
I'll go ahead and get that schedstat data for you.

Hi Mark,
Just another question (I think you've already told me once
but I can't remember :P). Do you have HT enabled on your
system? If so, you should have CONFIG_SCHED_SMT=y with -mm
kernels. If not, did you get to the bottom of why oprofile
with linus kernels says the system is P4 / Xeon, while with
mm kernels, it is a P4 / Xeon with 2 hyper-threads?

Here's a link to results with /proc/schedstat data on 2.6.5-mm5 with a
metric of 2191:

Before:

I have HT disabled with acpi=off.  No, never was able to determine why
oprofile kept saying P4 / Xeon with 2 hyper-threads with the -mm
kernels.  I'll ask on the oprofile list.
