[Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

[Glen Wernersbach]

[-- Attachment #1: Type: text/plain, Size: 1195 bytes --]

Hi All,

I install Xenomai 2.6.0 on AT91SAM9G20 system and have found that when
CONFIG_XENO_OPT_PERVASIVE is enabled my standard non real time linux serial
write then read serial program does not work.

If I turn off CONFIG_XENO_OPT_PERVASIVE, my serial program does work.

Any ideas why?????


Also, when you turn CONFIG_XENO_OPT_PERVASIVE you get this error:
CC      kernel/xenomai/nucleus/synch.o
kernel/xenomai/nucleus/synch.c: In function 'xnsynch_release_thread':
kernel/xenomai/nucleus/synch.c:688:3: error: implicit declaration of
function 'xnthread_get_rescnt'
kernel/xenomai/nucleus/synch.c:689:4: error: implicit declaration of
function 'xnshadow_send_sig'

I had to go in and make the code for that option be for it always false.

Glen

A possible explanation would be that your application links with the 
Xenomai POSIX lib (libpthread_rt), albeit it should not.

With pervasive support disabled, any routing from the overloaded POSIX 
I/O calls to the Xenomai kernel would then fail.

If so, you should not link against the Xenomai libs if you need no -rt 
service, or prevent symbol wrapping only for the POSIX I/O calls by 
prefixing them by __real_* if you want Xenomai-enabled POSIX services 
except the I/O support.

Re: [Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

[Glen Wernersbach]

I don't think this is it directly.

This program was made on the same kernel prior to patching it with Xeno.

It should still run like any other linux program.

- what does "program not working" mean in your case? Any errno return we 
could interpret? Any strace output?

- what if you disable CONFIG_XENO_OPT_SKIN_RTDM, leaving PERVASIVE on?

Re: [Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

[Glen Wernersbach]

I went through and disabled everything in xeno except
CONFIG_XENO_OPT_PERVASIVE, did not work. Take that option out and it works.

Take that option out at anytime it works.

My program basic writes a few characters a serial port and then reads them
back in from the same port. I have a loop back cable connected to the port.

It writes the data but waits forever to read them back in

>From my tests, it appears that the termois tcsetaddr settings is not getting
set when I call it when this option is on.

Can you strace your app when it runs, please?

Re: [Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

[Glen Wernersbach]

Working on the Strace.

I don't have the /proc/xenomai/hal file??

Again. Nothing I am running is xeno. Its just a xeno patched kernel.

Ok, but you do have the Xenomai co-kernel enabled in your kernel build, 
and the interrupt pipeline is enabled as well, right?

always exists.

That is completely outdated, please use one of the I-pipe patches which
comes with xenomai 2.6.0 (since you are using xenomai 2.6.0).

Re: [Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

[Glen Wernersbach]

My arm embedded system is set for 2.6.29 so I think I have to use that
patch. It was the latest one for that version.

Why closing and reopening? Are you sure this does not reset configuration?

The problem is that you may have a bug which has been fixed since then.
Is the code for that matrix500 driver available somewhere?

Re: [Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

[Glen Wernersbach]

Not much to that as well.

CC = arm-linux-gnueabi-gcc
#CC = gcc

all:    serial
serial:     serial.c
    $(CC) -o serial.o serial.c
    arm-linux-gnueabi-strip serial.o

clean:
    rm -f serial.o

Does this mean you received an error code from tcsetattr()? Or are you 
inferring this from the fact that you don't get any input from the 
serial link?

Re: [Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

[Glen Wernersbach]

I don't get any error from anything.

I just don't get anything back from the read command.

This is how the program behaved without the tcsetaddr command previously.

You do not know that, as you do not check write return value.

Any chance to see the driver code? Without that, I am afraid we can not

Note that this driver has the same issue as the vanilla atmel serial: it
may loose characters in case of high irq latencies.

Anyway, could you post the two kernel configurations, the one which
works, the one which does not work?

Other than that, I guess all you can do is try and debug the driver,
starting with the serial irq and trying and understanding how it gets lost.

I actually think in is in the settings because if run just the setup part of the code without reading and writing, on the kernel that works my activity LED turns off. 

On the xeno kernel the LED never changes.

I actually think that CONFIG_XENO_OPT_PERVASIVE does not make any
difference which could cause a difference of hardware behaviour. So, it
must be another option triggered by this config change. So, if you want
us to help you, please post the .configs.

Re: [Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

I know that there are some compile bugs if you turn off
CONFIG_XENO_OPT_PERVASIVE.

What is the downside to running without it?

Don't bother for these build bugs, they were innocuous and due to 2.6.0 
being the first code drop of a major release. The system is stable with 
or without.

PERVASIVE gives you real-time support in userland; if you disable it, 
you only have support for writing apps in kernel space directly on top 
RT drivers.

PERVASIVE is by no mean directly related to hw setup, serial links, etc. 
This is only about switching on/off the userland request channel to the 
Xenomai kernel, nothing else. So any interaction with a serial driver 
could only be really remote, and I can't think of any right now.

Disabling this option might simply change the kernel code layout 
significantly enough to trigger a completely unrelated bug, since the 
Xenomai footprints in kernel shrinks in that case, changing the code 
placement for sure.

Starting investigations from the matrix driver seems the best way to 
find the issue.

I am going to start trying to see if I can figure out what is not getting
set.

By the way. This board also has 4 other serial ports on a 8250.c driver. It
also fails under the xeno build.

But the serial console works, right? So there is at least on serial port
working.

You could get useful information from the pipeline tracer, by enabling 
CONFIG_IPIPE_TRACE, observing what exactly happens in kernel space from 
the issuing of the ioctl() syscall until the the read() syscall on the 
serial link.

You could set markers using Xenomai's I-pipe trace API in userland to 
highlight portions of interest in your app code, freezing the capture to 
snapshot a particular moment in the execution timeline. See
http://xenomai.org/index.php/I-pipe:Tracer.

NOTE: pay attention to the value in /proc/ipipe/trace/back_trace_points 
to hold enough data.

Hi guys,

One thing about both of these drivers is they have been modified to set some
GPIO pins.

The come down to the pca9539_gpio_set_value() in this file.

Do you see any reason why those would not take under Xenomai?

If these are input GPIOs to deliver IRQs, yes, in which case this might 
be a problem with the interrupt pipeline; as Gilles told you already, 
1.13 is fairly outdated.

But in that case, you should see the problem even with CONFIG_XENOMAI* 
fully disabled, provided CONFIG_IPIPE is still on.

If you don't, meaning that something in the Xenomai core does make a 
difference, then you could try disabling all Xenomai interfaces (i.e. 
CONFIG_XENO_OPEN_SKIN_RTDM, .._NATIVE, .._POSIX, etc.), only leaving the 
core enabled.

Re: [Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

[Glen Wernersbach]

I did disable everything except pervasive and the problem happened.

I disabled pervasive also, it went away.


I can try turning pervasive off and ipipe on and see what happens.

Re: [Xenomai-help] Linux Serial Does not work with CONFIG_XENO_OPT_PERVASIVE enabled

[Glen Wernersbach]

I figured out the fix. There was a hard coded minor number for a misc device
register for the GPIO.

For some reason PERVASIVE conflicted with it.

Changed it to dynamic assign ID and it worked fine.

Linux serial now works.
