[Xenomai-help] Latencies due to RT-Socket-CAN register accesses

[Xenomai-help] Latencies due to RT-Socket-CAN register accesses

[Wolfgang Grandegger]

[-- Attachment #1: Type: text/plain, Size: 831 bytes --]

Hallo,

in the meantime I have measured the latencies introduced through 
messages sent and received by RT-Socket-CAN. The SJA1000 register access 
times on my rather old PC with an Athlon 1100 Mhz are:

PEAK-Dongle: read  access: 11807 ns
PEAK-Dongle: write access: 11677 ns

IXXAT-PCI  : read  access:   729 ns
IXXAT-PCI  : write access:   305 ns

I measured an increase of the latency of approx. 170us with the 
PEAK-Dongle and approx 13us with the IXXAT-PCI card for the reception of 
a full CAN message (with 8 bytes payload). Sending messages is a bit 
less disturbing. I have attached a small patch to measure the SJA1000 
register access times when the driver is initialized. You are welcome to 
apply it on your setup and report the results. I'm especially interested 
in numbers for the ISA bus (or PC-104).

Wolfgang.

Hi Wolfgang,

Well these are convincing figures. Could you let me know what card (type 
number) you ran the tests on so that I am not unpleasantly surprised 
when I finally go to PCI.

I will continue development on my laptop with the dongle for the time 
being. It would be interesting to see what happens to the latency after 
your proposed changes are in effect.

Thanks,

Roland

It was the IXXAT PCI card currently plugged into my test PC but I 
actually recommand the PEAK PCI card. It's also much cheaper, I guess. 
Tomorrow I'm going to repeat the tests with this card ... stay tuned.

BTW, what are the latencies you measure on your system under load 
(without RT-Socket-CAN).

Off the top of my head 25us average 30us to 35us max. I am not sure I am 
"loading" the system though. How do I measure this load that is always 
talked about?

While the latency test is running execute in other windows:

- while ls; do ls; done
- ping -f <remote-host>"
- dd if=/dev/zero of=/dev/null

and let it run for a few hours. And also search the file TROUBLESHOOTING 
for "stress".

Wolfgang.

Here is a revised list of the register access times:

PEAK-Dongle: register read : 11705ns (  85428/sec)
PEAK-Dongle: register write: 11687ns (  85562/sec)

IXXAT-PCI  : register read :   725ns (1378643/sec)
IXXAT-PCI  : register write:   301ns (3311667/sec)

PEAK-PCI   : register read :   486ns (2057468/sec)
PEAK-PCI   : register write:   161ns (6201956/sec)

>>> I will continue development on my laptop with the dongle for the time

Non-CAN latencies will not be significantly affected but RT-Socket-CAN 
latencies will be worse due to overhead of interrupt handling by the 
service task.

Hi Wolfgang,

Just to answer an open question still

> > BTW, what are the latencies you measure on your system under load
> > (without RT-Socket-CAN).

lat min 20.952
lat ave 31.009
lat max 60.504
lat best 19.276

this was with the loading as you described in this thread and running
for 12 hours.

Anything special about the above figures? Not very good I presume but
I am not running with tsc enabled.

Kind regards,

Roland

The latencies depend a lot on the hardware. The minimal latency of 20 us 
indicates, that you have a rather slow system. Then a maximum of 60 us 
is reasonable. Note that worst case latencies of better than 20us are 
difficult to achieve, even with high end PCs.

Re: [Xenomai-help] Re: Latencies due to RT-Socket-CAN register accesses

[Roland Tollenaar]

Hi Wolfgang,

I think that this kind of latency should be fine for controller 
intervals of 1ms.

Another question:
The PC has a 3Ghz processor and an 800Mhz FSB. That should not class as 
"slow" in the conventional sense. What hardware is responsible for the 
latency i.e. makes the PC "slow" from the RT perspective? In other words 
what must one look at when purchasing a machine that should give minimal 
latency?

Regards,

Roland.

I ment "slow" in the sense of little CPU power, but that's obviously not 
the case. How have you measured these figures? With the "latency" 
program from the test suite? What is the min latency _without_ load? And 
also check Xenomai's TROUBLESHOOTING file. Already changing the kernel 
configuration to avoid latency "killers" might help.

Wolfgang.

Re: [Xenomai-help] Re: Latencies due to RT-Socket-CAN register accesses

[Roland Tollenaar]

Hi Wolfgang,

Typically without load the average latecny is 30 us and 20 us min 
latency. Yes I am using the latency program of the test suit.

Where do I check to find the latency "killer" settings? The 
powermanagement and all that s switched of. As is the PC speaker. What 
else can I look at?

Roland

Latency killers are detailed in the TROUBLESHOOTING guide.
Not all the power management is bad, ACPI is Ok, and is even recommended
except for the ACPI processor module.
Select a processor with a tsc and enable the local APIC if your hardware
supports it.
Make sure Xenomai debug features are disabled.

Here is what I get on a much slower PC (Athlon 1.1 GHz):
[root@domain.hid bin]# ./latency -p500
    RTT|  00:00:01  (periodic user-mode task, 500 us period, priority 99)
    RTH|-----lat min|-----lat avg|-----lat max|-overrun|
    ---|------------|------------|------------|--------|
    RTS|       1.309|       1.988|      10.723|       0|

Could you show us your .config file as Stephane ask for and the output 
of /proc/cpuinfo. Unfortunately, I have little experience with PC 
hardware and it's bad impact on the latency.

Wolfgang.

Re: [Xenomai-help] Latencies due to RT-Socket-CAN register accesses

[roland Tollenaar]

[-- Attachment #1: Type: text/plain, Size: 7378 bytes --]

Hi Wolfgang, Gilles, Stephane

In the intrim I have checked for latency killers and have found
nothing. I have a faster machine than you have posted the poerformance
of below yet I have substantially worse latencies.

Attached is my config file if you care to look at it.

One point may be USB. I am using usb pen drives and have seen in one
of the threads that USB (even if not used?) is considered a latency
killer.

Gilles suggested also to turn off the debug features but they were
turned off already AFAIK.

Sorry for the delay, I have not been able to work on this project for a while.

Ah and I have updated to 2.3.1 today, no problems but also no
improvement on the latency unfortunately. Just to eliminate that
point.

Kind regards,

Roland Tollenaar

The latency killers:
- SMI: check dmesg to see if you get a warning saying that an
  SMI-enabled chipset was detected. If yes, read the TROUBLESHOOTING. If
  no, and you have a fairly recent Intel chipset, then we probably need
  to add support for your chipset to the SMI workaround module, send us
  the result of lspci -vv.
- USB: disable legacy USB in BIOS configuration, sometimes it is not
  enough, and you have to _enable_ USB in kernel configuration, and load
  the USB modules (that is at least uhci-hcd, ohci-hcd, ehci-hcd and
  usbcore) so that they disable BIOS legacy USB emulation.
- X-window: if you see high latencies only when the X server is running,
  the X-server is probably causing them. A workaround is proposed in the
  TROUBLESHOOTING file.

In case all that fails, enable the I-pipe tracer, run latency with the
-f option, and check /proc/ipipe/trace/frozen once you observed the high
latency in latency.

Yes get this message.

>read the TROUBLESHOOTING. If
Done what it says here. No change. My latency is also less than 100 us
so this is probably not the problem. Tried anyway but as mentioned, no
difference.

> - USB: disable legacy USB in BIOS configuration, sometimes it is not
My BIOS settings do not allow me to switch off the USB legacy. At
least I cannot find the place where this is to be done.

These ARE enabled.

Ran latency without X running. No difference.

Have done this and attached the result. I have looked at it myself but
cannot interpret the meaning.

A bit of help would be appreciated.

Kind regards,

Roland.

Your machine looks overloaded with some VM activity. What does top say ?

Re: [Xenomai-help] Latencies due to RT-Socket-CAN register accesses

[roland Tollenaar]

is the same.

What is VM activity? This is completely novel to me.

Roland.

Hi Gilles,

There seems to be distinct improvement.
latency seems to improved structurally by 5 or 6 us.

I am not sure I have manged to entirely kill sound, followed your advice below.

Thanks.

Two conclusions:

 - You are running your kernel as i586 without TSC support - suboptimal,
   costs you a few micros.
 - The reported latency perfectly matches the trace, nothing
   pathological there. The trace looks like this: Timer fired,
   measurement task woken up, two interrupts squeeze themselves between
   wakeup and time stamp acquisition. All sane.

I am aware of this. For the current machine I will stick to this.

Is it not a bit strange that a machine as fast as this one is supposed
to be give worse latencies than much slower machines. Are the 2
interrupts causing the latency?

Those two increase the latency of code in timed tasks, for sure. The
question is if your measurement on the slower machine also included this
scenario (timer event + 2 IRQs in a row). This definitely doesn't happen
often, and maybe timing on the slower box makes it less likely. Or there
is one potential IRQ source more on your fast box (e.g. due to IRQ
sharing on the slower one).

You see, RT system design on the edge (ie. when hunting a few 10 us) is
tricky and not easily portable from box X to box Y.

Not complaining really, I think and I hope that the latency of 30us
average will do nicely for me. Just curious actually.

Its not possible to determine which IRQ's are responsible for this
from the trace I presume?

Then look at the "User Val." reported at "common_interrupt" (see also [1]).

Yes, what puzzels me is actually the high min latency of more than 24us:

  == Sampling period: 100 us
== Test mode: periodic user-mode task
== All results in microseconds
warming up...
RTT|  00:00:01  (periodic user-mode task, 100 us period, priority 99)
RTH|--lat min|---lat avg|-----lat max|-overrun|----lat best|---lat worst
RTD|   24.304|    35.199|      65.371|       0|      24.304|      65.371

Can the TSC cause such high delays?

And what is the output of "/proc/xenomai/latency"?

You mean TSC emulation? Definitely yes for the worst-case. Almost every
rthal_get_8254_tsc() costs about 3 us, and I counted >15 in Roland's
critical trace path.

> And what is the output of "/proc/xenomai/latency"?

Indeed interesting. Maybe the system is not well tuned. But the overhead
of rthal_get_8254_tsc() will remain for the non-minimal case (e.g.
host-tick hitting before or after task-wakeup tick).

Mind you this is slightly higher than when I run with a kernel without
i-pipe tracing enabled. Then it is more like

20    30

That just means that you have to add this figure to the measured 
latencies. It looks to me, that the TSC emulation is the cause of the 
problem.

Re: [Xenomai-help] Latencies due to RT-Socket-CAN register accesses

[Stéphane ANCELOT]

Hi Roland,

I only made a look at your xeno config.


looks like you used make config, try make menuconfig or make xconfig to
setup your kernel, more confortable...


I think your kernel config would need better and fine tuning,here are
some tips :
Disable swap in kernel config

lot of unuseful drivers are modules compiled. Setup only and only what
is present in your computer and may be used.
Furthermore, this will permit you to compile the kernel in a faster way.

I strongly advice disabling i2o too.

If you do not need pcmcia, turn it off too.

setup power managament off

CONFIG_M486 is settted up ? I read you had a 3GHz processor a few mails
before !!!!  ? Setup the right processor !!!!!


Best Regards
Steph

I know this but I am using a USB loaded linux with the intention of 
being able to run this system off many PC's without having to worry 
about drivers.

It is off!! Where did you see that it was on? Which setting?

>

I am afraid here you are right. Unfortunately this implies rebuilding 
all the drivers too (I tried and they are not compatible with 486 
kernels) and this USB bootable distribution makes changing the modules, 
well not impossible but pretty damn nearly impossible. IT does mean I do 
not have TSC support which I am aware, makes a big difference.

Thanks again.

Roland.
