EMC2 on Ubuntu 8.04 Hardy Heron - call for tests

[Alex Joni]

As most of you probably know, the latest version of Ubuntu has been
released: Ubuntu 8.04 Hardy Heron.
(http://www.ubuntu.com/news/ubuntu-8.04-lts-desktop)

As it is another LTS release (3 year support on the Desktop version - which
we use), we consider that it's important to have emc2 packages (along with
the needed infrastructure: patched kernel, rtai, etc) for it. Consiquently
we have built packages, a repository for them, and a LiveCD for easy testing
and install.

== Disclaimer ==

Before describing download and install procedures I would like to point out
that at this point the packages have been tested by a semi-large number of
people, and only a couple problems have been reported so far (on some
hardware where it doesn't work at all). Therefore I do not encourage at this
point to replace a working dapper install with the new hardy version. Dapper
is still supported until 2009, and as long as it's supported we will be
building emc2 packages for it. If you want to take part in the ongoing
testing phase for hardy, please read on; otherwise wait a couple days/weeks?
until we announce it fully released.

== Installing/testing procedures: ==

1. starting with a LiveCD (provides means for testing only, or even install
if wanted)

Step 1: Download the iso from:
http://www.linuxcnc.org/hardy/ubuntu-8.04-desktop-emc2-aj07-i386.iso (note:
this URL might change in the future, reference
http://www.linuxcnc.org/hardy/livecd.errata for the latest name, and for a
description of known problems).
Step 2: Check the MD5SUM (note: also mentioned in the livecd.errata, the
latest one is: 91c5abb84386091e0ff056e9ebc40fdb)
Step 3: burn the image
Step 4: boot it on as many PCs as possible (Note: the Hardy Heron LiveCD
needs at least 384MB RAM to boot in Live mode, or 256MB for installing, an
existing swap partition on the harddrive will be picked up, so it might be
possible to boot the Live version on systems with less memory).
Step 5: report problems encountered

2. starting with an existing Ubuntu 8.04 Hardy Heron install

Step 1: Install Ubuntu 8.04
Step 2: Once you have installed Ubuntu , get the install script from here:
http://www.linuxcnc.org/hardy/emc2-install.sh , choose "Save to Disk" and
click OK.
Step 3: Now an emc2-install.sh icon will appear on your Desktop. Right-click
that icon, select Properties. Go to the Permissions tab and check the box
for Owner: Execute. Close the Properties window.
Step 4: Now double-click the emc2-install.sh icon, and select "Run in
Terminal". A terminal will appear and you will be asked for your password.
Step 5: When the installation asks if you are sure you want to install the
EMC2 packages, hit Enter to accept. Now just allow the install to finish.
Step 6: When it is done, you must reboot (System > Log Out > Restart the
Computer) - once you have rebooted you can run EMC2 by selecting it on the
Applications > CNC menu.
Step 7: If you aren't ready to set up a machine configuration, try the
sim-AXIS configuration; it runs a "simulated machine" that requires no
attached hardware.
Step 8: If you experience problems with things that used to work on the
default hardy, but don't after installing emc2, chances are you need one of
the special modules. (you can install them with: sudo apt-get install
linux-ubuntu-modules-hardy-rtai).

== Reporting problems & getting help ==

Reporting issues/problems/nags/ideas for improvements or anything else, can
be done via email (on this list, or directly to me) or via IRC (#emc-devel
on irc.freenode.net). I will try to be available to a very large extent
during the next couple of days.

Thanks for your patience, and for all the help to make it another great
release.

Best regards,
Alex Joni

I started downloading now, but I already have a question.

On the Live CD, and then after installing, is there a realtine
performance test script ready?

In the old (2.1 EMD2 distro) I used a file with a script like this one:

/QUOTE BELOW

#!/bin/sh

sudo mkdir /dev/rtf; sudo mknod /dev/rtf/3 c 150 3; sudo mknod
/dev/rtf3 c 150 3;
cd /usr/realtime*/testsuite/kern/latency; ./run

/QUOTE HAS ENDED


If it is not there, may you please schedule adding it right on the
desktop? It will make testing the usefulness of different platforms
much easier and faster. As for the above script, I fould in on a
Windows drive, not sure if it is the same I use on linux...

Thanks.

That will work - also jepler wrote a nice gui latency test program. You
can run it from terminal by issuing 'latency-test'.

Yeah, I wanted all good available latency test scripts already saved
on the desktop. You come to a computer, live-boot the CD and click any
of the latency tests directly. It's good to save 5-10 minutes of time
that it takes to find those online.

Hi Mario,

here's how I usually run it:

1. emc's latency test:
open a terminal, type "latency-test" and it displays the values

2. RTAI's latency test:
open a terminal, type:
cd /usr/realtime-*/testsuite/kern/latency
sudo ./run

(the mknod part is not needed anymore).

Regards,
Alex

Alex, I understand you. But I will describe you the situation I was in
a hundred of times.

When I got access to an interesting PC computer platform, I booted the
linuxcnc CD. Okay so far. So I run or switch to terminal to run mc to
find the latency test. Okay, mc not found. So I fun firefox to type
EMC2 latency test into google. Okay, no network. So I try to get a
network cable or any other internet connection. When that is done, I
am able to do a search for my problem on the internet.

...A problem that should NOT have existed in the first place.

But sometimes I am not able to do that in a time limit I have access
to a machine that is not in my possession. Plus when I was doing that
in my work last year... I simply did not have time to pay attention to
that, I had tons of other tasks to do.

All I ask for is a method to provide latency test 2 seconds after
booting the linuxcnc CD. Nothing more or less. All methods requiring
starting a console basically require starting of firefox or some kind
of document viewer for anyone who does not remember the exact syntax
or location or anything. That is why I asked for the two icons with
testing presets. (now it could be 3 with the graphical inetrface test
script)

Regarding latency test, I have recently made some experiments with about
5-6 different computers. One of them performed reasonably well and the
others has the infamous SMI problem.

I searched the wiki for a solution and I found one, that requires
recompiling, after following the instructions, NO SUCCESS.

The I searched Google and found this

https://listas.upv.es/pipermail/rtlinuxgpl/2007-April/000609.html

It is a simple and very little standalone utility that allows to switch
off entirely the SMI.
I where able to perform good latency test in all the computers using
that trick.

I think that such a utility could be included with the new release.

Also I think that it can be reference in the wiki section related to
latency and SMI problems as an alternative quick solution.

Bye,

Javier

You don't need to recompile anything.
The instructions in the wiki are for Dapper Drake, where the RTAI module
rtai_smi is not ok.
On Hardy you would only need to load the rtai_smi, and it should work
ok.
I looked at both sources (RTAI: smi-module.c and smictrl.c) and I think
the smictrl.c is based on an older version (based on Xenomai, which
forked from RTAI).
So my guess is that something might have happened, and the module didn't
load correctly (the rtai_smi one).
Can you try by hand and see what happens?

I used this to disable SMI:
sudo insmod /usr/realtime-2.6.24-16-rtai/modules/rtai_smi.ko
sudo rmmod rtai_smi

and later to re-enable:
sudo insmod /usr/realtime-2.6.24-16-rtai/modules/rtai_smi.ko smiReset=1
sudo rmmod rtai_smi

Regards,
Alex

PS: the proper fix for a machine on which you want to run emc2 is to put
rtai_smi into /etc/emc2/rtapi.conf (even if it says don't edit this
file ;)

Alex,

Is there a PGP component I need to install or is the pgpkeys server really
timing out? I am getting the following errors:

gpg: requesting key 8F374FEF from hkp server pgpkeys.mit.edu
gpg: keyserver timed out
gpg: keyserver receive failed: keyserver error
gpg: WARNING: nothing exported

Complete log included below.

Thanks,
Eric

Usually it works, you should try again (probably some network problem
when you had that).
Also if it still doesn't work, you can look at the emc2-install.sh, and
run the commands one by one.
Something failed (besides the pgp part), because you don't seem to have
http://www.linuxcnc.org/ in your /etc/apt/sources.list
