[Xenomai-help] no-brainer realtime issue

[Steven Seeger]

I have a xenomai userspace application that does the following:

A thread of priority 90 toggles a bit (outb) to move a stepper motor.

A thread of priority 10 updates the display once a second.

The motor thread is periodic and uses rt_task_wait_period(). The display
thread just uses sleep(1).

My question is this: the priority 90 thread is higher priority, and doesn't
do anything relating to linux system calls. Whenever the display thread
updates the display, the motor thread stalls momentarily.

Any idea why this is?

Steven

X-window graphic card driver masking hw IRQs? You should see that too when running 
the latency tests while moving windows around the desktop.

Btw, how to you measure/observe the stalled state?

If your motor thread really looks like

while (1) {
	toggle_bit();
	rt_task_wait_period();
}

you may suffer from contentions of the related bus towards your motor
(what kind of interface do you use?).

To test this, just put some instrumentation around the toggle_bit()
(take timestamps and look for abnormal delays). What frequency is your
motor thread running at?

If there is more code in your loop, please post the program (or a
simplified but still failing version).

Additionally, the output of /proc/xenomai/stat for a failing run might give some 
useful information.

I'm using the gx1fb framebuffer for the geode. However, since this problem
occurs even when the VT outputting the text is not active, I don't think
it's fb related.

The latency output is just a bunch of numbers. :P

Here is some output with the latency -p 500 command, and halfway through it
I put a 100% load on the cpu.

Until those numbers are sane, there is no point in trying anything else though.

Ok, the testsuite clearly fails on your board, and something in the current setup 
prevents any real-time use. .config would help.

Maybe I didn't set it up right? I followed the instructions in the
README.INSTALL file. Attached is my linux tree's .config.

Hehe I misread that option. I read it as "disable SMI" and intended for it
to be on. I'll try that. :)

Turning on the SMI disable stuff, rebuilding the kernel and modules, and
installing everything to my board did not solve the latency problem. My
numbers keep growing as the latency tester runs.

Any other ideas? I've never had an rtai/xenomai/fusion/whatever system fail
basic realtime requirements like this before in the 4 years I've been using
this geode board.

Yous seem to be running in periodic timing mode, with a default slice of 125 us.
Which parameters are passed to rt_task_set_periodic() and rt_task_wait_period() in 
your sampling task?

I am confused why this matters? You said the latency test shows my realtime
does not work, so clearly the problem I have isn't specific to my code, but
rather to my system, right?

Here is my call to rt_task_set_periodic:

rt_task_set_periodic(&task, TM_NOW, rt_timer_ns2ticks(500000));

I don't pass any parameters to rt_task_wait_period()

The latency figures obtained are totally braindamage, so either something weird is 
happening in 1) the real-time core, or 2) with the hw config selected, or 3) in 
the application.

1) is always possible, but you might also consider that early timer shots beyond 
two _milliseconds_ (-2293218 ns) would have been caught by a few other people on 
the list; this has not been the case yet. So considering a massive breakage in the 
real-time behaviour of that magnitude at this point of the investigation seems a 
bit premature.

2) Geode brings its own set of issues. SMI is one of them. Something may also go 
wrong when upgrading a kernel while reusing an old config file. Given your past 
answers, I now take for granted that it is not the case, but asking first is better.

3) v2.1 has changed a lot of things wrt v2.0, including the way some key 
configurations are made. Timing mode is one of those critical changes, and maybe 
one of those changes has had a negative impact in some unexpected way. Looking at 
the application to see what it requests to the real-time core and how it does it, 
is the usual way to start digging the issue.

Ok, I think we might be dealing with a timing mode issue. Could you try disabling 
CONFIG_XENO_OPT_TIMING_PERIODIC in your kernel config (Timing menu) and re-run the 
latency test? TIA,

Yep, my mistake.

Could my problem be caused by me using the latest SVN for xenomai? Should I
try the released version instead?

You should first try my last suggestion, i.e. disable the forced periodic support 
from the configuration. If your application used to rely on the deprecated 
rt_timer_start() call for setting the oneshot mode, then enabling the periodic 
timing option is inappropriate.

At the very least, it is inappropriate for running the latency test and explains 
the strange results.

No, my application uses and always has used periodic timing with a tick of
125 us.

Re: [Xenomai-help] no-brainer realtime issue

[Steven Seeger]

Just to let you know, I tried recompiling everything without periodic
support enabled and I can't even load the xeno_nucleus.ko module. I get an
-ENODEV presumably because my board won't work with the aperiodic timing
mode.

Could you try and configure the timer in aperiodic mode ?
