Cyclictest expected results

[Jaswinder Singh]

Hello all,

I am testing Cyclictest. And looking for results as in :

http://rt.wiki.kernel.org/index.php/Cyclictest

Here are my results on Intel Pentium 4 :

Command line :  ./cyclictest -t 1 -p 80 -i 10000 -l 10000 -q

>From where I can get Linux-2.6.16-hrt5 and Linux-2.6.16-rt12 patches.

CONFIG_HIGH_RES_TIMERS=y are defined in .config then why I am getting
"WARNING: High resolution timers not available".

Why my results are not so impressive in realtime even though I defined:
CONFIG_PREEMPT_RT=y
CONFIG_PREEMPT=y
CONFIG_PREEMPT_SOFTIRQS=y
CONFIG_PREEMPT_HARDIRQS=y
CONFIG_PREEMPT_BKL=y


Min, Avg and Max are showing cyclic latencies. Ideally It should be
ZERO. Am I right ?

Thank you,

Jaswinder Singh.

Can you post the output of /proc/timer_list?

That one should give you sane results.

> From where I can get Linux-2.6.16-hrt5 and Linux-2.6.16-rt12 patches.

I don't think it makes much sense to play with such an old kernel any more.

Doesn't look too bad. Are you sure you actually _bootet_ that kernel? :)

You won't get zero. On x86 these latencies should be well below 100 us
maximum time, with an average in the lower 10 us range.

The output of /sys/devices/system/clocksource/clocksource0/available_clocksource
and a full boot log are more interesting.

We need to know, why the box did not switch into high resolution timer
mode, which is not visible from the /proc/timer_list output.

Those results _are_ sane for a non high resolution timer kernel.

We need to look at the information I requested above. I'm not good in
witchcraft :)

Hmm, it would show which clock event devices are currently selected.

Yup, sure. It's probably not what the original poster considered to be
sane for a hrt realtime system :)

Oh, sorry, no offense intended. I assumed you'd read your core mailing

Right. But it does not tell us _why_.

Well, it is not hrt enabled for whatever reason.

In general it's not a good idea to trim cc lists, but assumptions of
other peoples mail reading habits are definitely a _bad_ idea.

Thanks,

Can you try to enable ACPI on the box and check if you get an acpi_pm?

Re: Cyclictest expected results

Dear Robert,

I am sorry for delay.

By enabling ACPI on my PC I get acpi_pm

I am also getting :
root@rd cycletest]# ./cyclictest -t 1 -p80 -n -i 10000 -l 10000 -q
T: 0 ( 2709) P:80 I:10000 C:  10000 Min:      8 Act:   16 Avg:   16 Max:      44

T: 0 ( 2723) P:80 I:10000 C:  10000 Min:     21 Act:   30 Avg:   29 Max:     139
[root@rd cycletest]#

These numbers are quite impressive as compared to old numbers.

Thanks for your help.

I am quite strange why I start getting RT performance with ACPI. why I
need ACPI on my PC, I dont even use ACPI on my Laptop.

But I am not able to see performance difference in my GNOME
Environment. It is still very very slow, how can I boost X-Windows by
-rt patch.

Thank you,

Jaswinder Singh.

Doesn't look too bad.

acpi_pm provides a proper clocksource to your system which is a) sane
and b) has enough resolution.

I'm not sure what you are expecting here? Realtime is about guaranteed
latencies, not about speed.

Currently my GNOME environment takes 150 seconds to start.

May be it because of some bug :
mtrr: base(0xf0020000) is not aligned on a size(0x300000) boundary
[drm:drm_unlock] *ERROR* Process 2382 using kernel context 0

I am just curious can we improve its performance by Realtime.

Yes, you are right we cannot do anything if CPU is already running 100%.

Thank you,

Jaswinder Singh.

There are many reasons why GNOME performance might be slow.  Stupid
application design going to helped by some magic kernel patch.  Keep
in mind the GNOME doesn't run with real-time priority levels; neither
does the X server.  

The -rt patch isn't magic; no RTOS is magic.  A large amount of
application design and reworking in order to properly utilize the
POSIX real-time interfaces.

Also keep in mind that by its very nature, -rt is more sensible to bad
coding and bad application design. Some applications that perform well in
mainstream linux may present bugs in -rt (those bugs exist in the code but
are more prone to show uo in -rt).

People here have been working most of time focused on determinism.
Eventually it comes with a performance enhancement bonus. Sometimes not.

139 microseconds interrupt latency looks not too bad for Genral purpose OS.

But this is still bad in Realtime point of view.

Thank you,

Sigh. Realtime is not as fast as possible, it's as fast as
specified. It depends on your requirements whether it is sufficient or
not.

Also cyclictest is not about interrupt latency, it's about the full
chain of:

	timer interrupt
	scheduler
	user space execution

in the second test you did it's:
	
	timer interrupt
	softirq + signal delivery
	scheduler
	user space execution

	The softirq processing is causing the longer latency here.
	This problem is known and it can be fixed, but it's not high
	on the priority list.

Thanks,
