[Xenomai-help] RTCAN and tsc

[roland Tollenaar]

Hi,

One thought did occur to me wrt to the problem of rtcan breaking RT
behaviour. I am not using TSC support (IPC's we have are all 486
processor family). I was told that this will give slightly worse
latency but at a 1ms period time this should not be a problem.

Just want to confirm at this stage that this is still correct?

Just run latency -p 1000 with some load. If you observe abnormal
latencies with the latency test, then you have a hardware problem. If
you observe normal latencies with the latency test, then your
application has a problem.

To get reliable results, you should run the test for a few hours. Not 22
seconds.

Ah. Will do so. But the problem I am having with the RTCAN gives
latencies of the order of 0.2ms fluctuating heavily and visible
immediately.

No matter what else I do with my system ,even downloading email to
thunderbird while sending this email to you and compiling another
program at the same time hardly disrupts my apps period times that
much.

0.2 ms is 200 us, so I would say that the latencies you observe are
consistent with the results of the latency program.

Hi

I need to be educated a bit here if you don;t mind.

What you see above (up to where max latecy jumps to 200) is the
behavior while my application is running but the node (rotary encoder)
is not moving so not sending any position signals. The moment I start
turning the encoder shaft the jump takes place.

What does output of latency mean? Is the above result simply stating
that I have a crappy hardware structure and will never be able to
achieve better latency or does it tell me there is something wrong
with my application?

Enable the I-pipe tracer, recompile your kernel, set
/proc/ipipe/trace/back_trace_points to a larger value, and run latency
with the -f flag. Show us the contents of /proc/ipipe/trace/frozen, and
we may be able to give you an answer.

For more details on the I-pipe tracer, see:
http://www.xenomai.org/index.php/I-pipe:Tracer

What value must I make this?

Will do.

A value large enough to catch the 200 us latency. I would start with,
say, 2000 and increase if need be.

Attached find the traces. The first one , frozentrace.txt is without
my application running.

The frozentraceApptxt with my app running and frozentrace_rtcanrecv
with the node  alive but only read by rtcanrecv.




Hope this helps?

What does this mean? This is as good as it gets? That is a problem. I 
have a couple of thousand euros of new hardware betting on xenomai/rtcan 
being real-time enough to do some serious feedback control of machinery. 
Must I put that up for sale now? I'll start writing my resignation 
letter......:(

But more seriously rtcan_sja_interrupt I presume is a routine (interrupt 
handler?) by the sound of things related to the sja chip. Is the 
conclusion that something is wrong in rtcan_sja? Surely timing 
inconsistencies of 200 micro seconds cannot be design?


I will not be able to work on this tomorrow. So if I make less noise on 
the list its only because I am on a plane not because I have lost 
interest. :)

Roland

Hm. To be more verbose on what happens between the beginning of 
rtcan_sja_interrupt and rtcan_rcv please remove the "inline" from the 
functions rtcan_sja_err_interrupt in the file 
ksrc/drivers/can/sja1000/rtcan_sja1000.c line 156 and from the function 
rtcan_sja_rx_interrupt in the same file in line 87. Compile your 
modules/kernel again and repeat the tracer/latency test.

I assume that most of the time is spent in the latter function where several 
SJA HW regs are read out. A slow access to the regs could be the explanation 
for the long time the interrupt handler has to spend.

Where are the registers located? On the dongle or are these in the PC? 
Just to know whether there might not be a problem with the PEAK device. 
Is there any way you could check what the access times are to 
rtcan_sja_interrupt on your systems when performing the same experiment 
and recieving messages (pref PDO with length 8) over the bus?

I am developing on a pretty high-end machine here, in fact every aspect 
almost as fast as is on the market at the moment so its would surprise 
me if there is a hardware shortcoming if the registers you speak of are 
on the PC.

In the mean time I will try doing as you suggest, I presume you want me 
to send the frozen trace to you again after that.


Is it worth while removing the virtual driver from the kernel build and 
running over rtcan0. Is there any chance that you have never encountered 
this problem

These are registers located in the SJA1000 CAN controller.

Unfortunately, I do not have the opportunity to perform tests with the driver

Turn it off although it is unlikely that it has something to do with the

RE: [Xenomai-help] RTCAN and tsc

[Bernard Dautrevaux]

Hi everybody,

Maybe I'm making an error, but AFAIK, the SJA1000 on-chip registers are clocked by a rather slow clock, that is limited to about 24MHz. I remember a case where interrupts were handled by the CPU (a 600MHz thing) too fast for the SJA1000, resulting in the chip not yet aware that it generates the interrupt. 

To be more precise, the IRQ gets out, probably immediately through some sort of asynchronous logic, but the fact was only clocked in the interrupt status register at about 16MHz, thus the CPU was able to read the interrupt status register, thus clearing the coming interrupt state, before the interrut was latched, and thus the IRQ was lost...

The net result was that we had to add quite a lot of udelay() calls to slow down the driver to the senator's pace of the SJA1000... Are you sure you're not running in this kind of problem?

Just my .02€

Bernard

[Roland Tollenaar]

Hi,

Thanks for the input. Much appreciated from my side. I cannot comment on 
your question

 > The net result was that we had to add quite a lot of udelay() calls 
to >slow down the driver to the senator's pace of the SJA1000... Are you 
 >sure you're not running in this kind of problem?

but if anyone has suggestions as to what I can do to validate it I would 
be happy to try.  (Sebastian your request to remove the inline statement 
is forthcoming)

For the record, I am developing on a laptop with 3 GHz Intel CPU, 2 GB 
of RAM, 800 Mhz FSB and that is about all the stats I have. This info is 
probably irrelevant but just to clear out of the way any ideas that I 
might be working on the oldest of PC hardware.

I do have a question which may be a bit early or out of context but if 
it turns out without question that the delay IS in the

rtcan_sja_interrupt

routine (is it a routine? A function call? ) would it be possible to 
split the function up into smaller parts (is this what they call 
granularity?) so that the RT tasks can return to themselves before 
running out of time while stuck in the rtcan_sja_interrupt call. ?

Or am I missing the point entirely?


Regards,

Roland.

There are no delay calls inside the interrupt handler. If the handler would be 
too fast for the SJA1000 it would immediately return.

As the name states it, this is the RTCAN interrupt handler for the SJA1000 
driver.

If an RX interrupt appears it it necessary to read out up to 14 SJA1000 regs 
and write one register before a CAN message can be distributed to the 
sockets. Do you really suggest that the reading of the SJA1000 registers 
should be interruptible? One step towards chaos, I would say.

Maybe it would make sense to handle the message reception in a thread (a
kind of bottom half), and to only disable the CAN irq when doing the
reception work. This way, the system would still be able to handle other
events while the can reception takes place.

The SJA1000 interrupt handler consists of several parts:
1. Read out the interrupt register to determine which kind of CAN interrupt 
raised
2. Check for the different kind of interrupts (error, TX, RX)
3. If RX:
3a. read out HW registers
3b. Distribute to sockets

It seems that an extended amount of time is spent for 3a. If we do this in a 
bottom-half we have to deal with things like priority inversion and under 
certain circumstances with lost CAN messages due to a full HW RX buffer of 
the CAN controller.

So, maybe it is possible to simply enable interrupts in the interrupt
handler with only the CAN interrupt disabled ?

This requires a detailed review of the driver code because every access to the 
CAN HW registers are protected by a rtdm_lock_get_irqsave and the SJA1000 IRQ 
handler relies on all IRQs being off.

But as far as I see, the PI and the HW buffer overflow problems would still 
exist.

RTnet documentation recommends to use
      rtdm_irq_disable(&priv->irq_handle);
      rtdm_lock_get(&priv->lock);

instead of rtdm_lock_get_irqsave(&priv->lock);
when the critical section is about to be long. The point is that the can
irq would still be off, it is unlikely that you have to protect from irq
handlers of other drivers.

The point is to make some code area atomic. If several tasks and an interrupt 
handler could access the registers of the CAN controller, it is wise to let 
them do it in an ordered manner from defined controller states.

If a high-priority task blocks on an rt_dev_recv and the IRQ handler would be 
interrupted by a task of lower priority while getting an received CAN 
messages out of the registers we would face priority inversion. So we have to 
give the interrupt handler a priority.

The CAN controller receive buffer would overflow if the RX interrupt routine 
would be interrupted and, before being finished, the controller would receive 
more messages than its buffer can hold.

To say just "atomic" is not enough, it always involves /against what/.
One doesn't need to be more "atomic" than necessary.

What Gilles pointed out is that if those registers are not accessable
from other ISRs, there is no need to keep all the interrupts off. ISR
may compete either with another ISRs on the same CPU (nested
interrupts) or against any other code on /another/ CPU. But that's why
you still have spinlocks in place.

How come a RT ISR (I suppose we are talking about the RT driver - the
primary domain ISR) can be interrupted by /any/ task? Do you have some
special threading IRQ handling mechanism in RTDM (or maybe a patch
that comes with RTCAN) that allows it?

There are several places in the SJA1000 driver where HW registers are read or 
written.  If those code pathes would be interrupted before e.g. the read 
values are stored properly they could lead to wrong effects.

Maybe I'm mixing things up or am just thinking too far. The initial problem 
was: The RTCAN interrupt handling seems to last too long so that RT tasks may 
be delayed inappropriately. So the proposed solution was: Make a bottom-half 
so that another RT task could run. That was the base for my speculations how 
to change the RTCAN code best. But it's only a thought experiment. No code, 
no patch. And I'm open for any findings coming out during this 
discussion. :-)

Well, I suppose, we all know how important synch-safe code is. So no
need to repeat mere generic ideas again :) I was pointing into
particular synch scenarious btw.

The point I made (and earlier Gilles) is that an ISR in the primary
domain cannot be interrupted by anything if irqs are *off*.
If irqs are *on* but the line on which this ISR resides is *off*, it
can be interrupted only by another ISR. And hence we come to the
point:

"The point is that the can irq would still be off, it is unlikely that
you have to protect from irq
handlers of other drivers."

So if you don't have another (or even the same) ISR sitting on
*another* irq line and accessing the same set of can registers you
don't need to keep all the interrupts *masked* - esp. if you know that
processing may take quite some time.

If you want to synch against ISRs from some code in the thread context then use

spinlock + irqs off.

Yes, spinlock + only a particular irq line being off would be ok as
well (and less strong restriction) but the point is that:

(1) irqs masking/unmasking is normally way faster than
disabling/enabling a given line.
that's important as long as (2) is true;
(2) such "atomic section" is normally supposed to be short, time-wise.

Another problem of the long Rx ISR just occurred to me. If that ISR
cannot be interrupted by my task and messages are continuously coming
in on the CAN bus, that ISR will run contiguously during a task cycle
allowing no time for any "work" to be done in the task.

Is that correct?

What is the effect of the buffer overflow? Only messages being lost or
are there more serious consequences? Error states of some kind?

What I gather is that allowing the CAN-RX interrupt handler to be
interruptible could lead to undesirably long delays while reading out
the registers which would either result in buffer overflow or/and,
changed register content before the previously read values are
written?

If it is also not possible to optimize the code further then IMHO  we
are looking at a fundamental hardware constraint.

If the latter is true then to be of any use in a RT environment, it
must be possible to retain more control over the message receiving in
at least one respect. It must be possible to either block the CAN-RX
interrupt or the reaction to it of the ISR. Obviously at the cost of
loosing messages but in some cases (like mine) loosing messages is not
that much of a problem. Having excessive latencies on the other hand
is.

What would probably work in my case is to allow the Rx ISR to be
interrupted by the rt tasks in such a manner that when the ISR is
interrupted the ISR is exited with no values written to the the
sockets. Obviously the current message in the registers of the SJA
will be lost but there is no risk of corrupt messages.

I think it was Sebastian that said there are 14 reads and one write per 
interrupt - If this is the case, then looking at the Peak parport dongle 
driver, I see eight IO instructions per read and six per write. A total of 
118 inb(). outb() calls - Not a particulaly large amount, however, a standard 
parallel port takes one to two microseconds to service each call, so 200uSec 
for the interrupt handler would quite reasonable..

 One way to reduce the time spent servicing IO instructions would be to switch 
to a PCI based parport card (not sure if it would be compatable with the 
driver & dongle).. Or alternatively use a PCI CANbus card.

There is no way I can comment on that. But I am happy to believe it.
What baffles me a bit  then is that the behavior cannot be classified
as very "Real-Time" can it? I cannot imagine that the developers of
rt-can overlooked this. I doubt that it will be possible to run a
discrete state-space controller successfully on a platform that
juggles around its period-times as badly as I am experiencing. And I
still need to read discrete IO and write DIO and AIO to another CAN
node which is not yet even connected.

Developing from a laptop using PCI cards is a bit uncomfortable. Hence
the choice for the parport. Also what improvement could I expect?
Latencies of 100 micro seconds are still not that fantastic. Strangely
I have used CAN like this in a vxWorks environment where I was never
aware of CAN disrupting RT behavior this badly.

I am only "listening" the conversation for learning a bit about
xenomai usage and I am no CAN expert, but

I think your implicit comparison is not fair.
You seem to compare CAN usage under VxWorks on hardware
which may be far away from your laptop + parallel port CAN I/F
with Xenomai don't you ?

By the way I understand that your conclusion may be that
using Parport CAN I/F on Xenomai Laptop does not fit your need.

Am I ? It was running on a PC 486 but indeed with a PCI based CAN
adaptor. And I am not saying it was any better, only that I was not
aware of any latency problems. Who knows, maybe this problem is
inherent to CAN via sja chip on PC's?

Are you telling me this? Or asking? I have not drawn any conclusions
yet. Don't know enough about the driver to be able to tell. This
"bottom half" thread matter sounds rather interesting. ;-)

Real-Time does mean the system reacts in time. There is nothing a
software can do if the hardware is not meeting your requirements of
beeing in time. Having reliable 0.5 ms real-time is e.g. for us
absolutely real-time and we chose carefully our hardware components that
this will never be exceeded. For us Xenomai and RTCAN on a MPC5200B
platform do a good job.

Choose your hardware carefully. Parallel port CANS are certainly much
slower than e.g. PCI adapters. On a Laptop you have the possibility to
add e.g. PCCARD CAN. But before purchasing I would check how these are
supported and which typical access times you can expect. USB CAN is
certainly even slower, so this will be no option.

Best regards,

Daniel Schnell.

You have my attention here. What exactly do you mean? That you have
consistent 0.5ms cycle (period) times and your platform maintains this
to within a few (<10) micro seconds?
Or are you saying that latencies of 0.5ms are still acceptable for
your application and with regard to the time-scales of your physical
process latencies of 0.5ms are still regarded to be real-time?

What CAN adaptor are you using? Not the dongle I suppose?

Can anyone quantify this?

AFAIK rtcan only supports Peak PCI and PEAK dongle devices. Hardware
vendors don't generally provide xenomai device drivers. This kind of
limits my options.
Besides CAN are there any other protocol devices supported?

And is apparently not compatible with anything real-time from what i have heard.

To confirm that, the PCAN dongle is a nice cheap device for low CAN 
speeds but not appropriate for 1MB/s. Please ask PEAK for more detailed 
information (e.g. linux@domain.hid).

Agreed. Still if it can be interrupted which I have the feeling should
be possible it will function just fine.

The core question I have at the moment is whether or not it is
possible to make the receive interrupt handler interruptible.

Incoming messages which get no place in the receive buffer of the

The discussion was a little bit theoretical. This would only apply if we 
shift some code from the handler to a bottom-half thread, which would then 
be interruptible by a higher prio task. But I'm not planning to do this.

Paul already posted some calculations which make the situation rather

With every reception you get those "excessive" latencies on your hardware. 
Which one will you choose to be suppressed? A rather difficult task, I 
could imagine.

This requires a conversion of the driver which is not done in five 
minutes. And whether this is the way to go remains yet questionable.

Ah. :(

I thought so too.

Is it? Perhaps I am being rather over optimistic but I am not
interested in position readings coming in at the end of the 1ms
period. If I could block the RX interrupt for the last 0.2ms of my
task the chances are that I would have perfectly acceptable readings.

I feel that if we are facing a fundamental hardware constraint and
making the ISR interruptible is "impossible" there are not many
alternatives. I don't deny that the suggestion is a serious compromise
but there are applications where it can be used. Mine possibly being
one of them.

Hi I tried this for you but come a bit short. When I try to load the
module I get the error

FATAL: Error inserting xeno_can_peak_dng (xeno_can_peak_dng.ko):
Unknown symbol in module, or unknown parameter (see dmesg)


with dmesg:

xeno_can_peak_dng: Unknown symbol mcount


What I did was simply remove the inline statement from the function
call. (I did not check the corresponding header file should I have?)
Then I did a make modules and a make install_modules after which I
retrieved the .ko files which I am trying to load.

Is this still a useful step after Paul's elucidating calculations ?

Roland

That is still to discover. Please change the priorities of your RT Tasks lower 
than 99 and run again, Alternatively, do it with rtcansend/rtcanrecv as I 
told you before.

Below is the output with those running. The node is active but not
moving and then the jump when the shaft is rotated.

My application is NOT running during this experiment.

As Gilles pointed out, 0.2ms are 200 us so nothing special here.

Could you run latency when receiving CAN messages? Please do it again with 
rtcansend/rtcanrecv without your app.
