[Xenomai-help] Xenomai not booting on a dell server

[Saravanan S]

[-- Attachment #1: Type: text/plain, Size: 1495 bytes --]

Hi,

      I am trying to install xenomai on a Dell Poweredge server (R710).The
platform details are given below:

Two quad Intel(8 cores) Xeon E5506@domain.hid 6,RAM-16 GB,uses SAS
disks through a SAS Host Bus Adapter(HBA).

Drivers for this HBA only available from fedora 10 onwards.

So I patched xenomai  2.4.10 with linux 2.6.29.4 with fedora 11 as the host
OS.I used fedora 11 config file.I made the following changes to the config
file

1.In processor types and features: architecture->Core2/Newer Xeon,
subarchitecture->Generic, thermal throttling disabled,HPET support enabled

2.Power management stopped.

3.Support for PCI hotplug disabled.

4.MSI,MSI-X disabled.

5.In real time subsystem all options selected.

6.SMP support enabled

7.MTD support disabled

8.All other default options.

After making and installing the modules ,when i selected the xenomai kernel
on rebooting it didnt boot at all.There was just a blinking cursor on the
screen.

I referred to the following documents while installing

http://download.intel.com/design/intarch/papers/322386.pdf

http://stud3.tuwien.ac.at/~e0226686/xenomai/xenomai_implementation.pdf<http://stud3.tuwien.ac.at/%7Ee0226686/xenomai/xenomai_implementation.pdf>

http://www.lara.ene.unb.br/~phsantana/files/technotes/HowTo_Debian_Embedded.pdf<http://www.lara.ene.unb.br/%7Ephsantana/files/technotes/HowTo_Debian_Embedded.pdf>


I would love any suggestions and help in this regard.

Thanking you in advance.

With Regards,

S Saravanan

Bad. You should enable ACPI, only CONFIG_ACPI_PROCESSOR should be disabled.

No reason to do this. If you enable these options and get problems,
please isolate the option which causes a problem and report.

Please keep the default settings for a first run, verify that it works,
then enable the options you want (all of them if you want), if it does
not work, then isolate the option which is the cause of the problem.

Did you rebuild your OS (which is it anyway ?) initramfs/initrd? If you
do the same procedure without activating CONFIG_IPIPE and
CONFIG_XENOMAI, do you get

That is fine and even flattering to see that there are paper about
xenomai all around the web and even on intel's site. However, the
website containing authoritative documentation is http://www.xenomai.org
If something is missing there, please ask.

I read the Intel doc for instance, it contains a lot of things which are
a cut and paste of Xenomai documentation, with some added stuff, which
unfortunately is quite erroneous:
- Adeos is not a real-time kernel
- there is no such thing as a list of linux kernels compatibles with a
version of Xenomai, each version of Xenomai aims at being compatible
with each versions of a Linux kernel for which a patch has been issued
at the time of the release. For each architecture, there are several
patches contained in the package, you are insured that linux kernel
patched with these patches compile, and that the one with the highest
linux version has been tested to validate xenomai.
- the list of packages to install in order to be able to install xenomai
is extravagant. The following packages are not needed:
rpm -ivh libgomp-4.1.2-42.el5.i386.rpm (Disk 2)
rpm -ivh elfutils-libs-0.125-3.el5.i386.rpm (Disk 2)
rpm -ivh redhat-rpm-config-8.0.45-24.el5.noarch.rpm (Disk
2)
rpm -ivh ncurses-devel-5.5-24.20060715.i386.rpm (Disk 2)
rpm -ivh elfutils-0.125-3.el5.i386.rpm (Disk 2)
rpm -ivh libstdc++-devel-4.1.2-42.el5.i386.rpm (Disk 2)
rpm -ivh doxygen-1.4.7-1.1.i386.rpm (optional, Disk 2)
rpm -ivh unifdef-1.171-5.fc6.i386.rpm (Disk 3)
rpm -ivh rpm-build-4.4.2-48.el5.i386.rpm (Disk 3)
rpm -ivh emacs-common-21.4-20.el5.i386.rpm (required for
emacs-nox, Disk 3)
rpm -ivh emacs-nox-21.4-20.el5.i386.rpm (optional,
Disk 4)
- when building a linux 2.6 kernel, you do not need to run make clean
before building the kernel, actually, it is a waste of time
- the list of options to disable to run with xenomai is extravagant too:
you should not disable power management, you should enable ACPI, and the
MSI and MSI-X should work
CardBus should work
I suspect Toshiba and Dell laptop support should work
PCI hotplug should work
MTD should work (and actually works on embedded platforms with MTD devices)
Fusion MPT should work
I2O should work
ISDN should work

Anyway, if you have problem when enabling these options, writing a paper
telling the rest of the world to disable them is the wrong approach, any
such issue should be reported on this list.

... the same behaviour?

Systematically disabling the SMIs is not a good idea either, what to do
is documented in the TROUBLESHOOTING guide in Xenomai sources distribution.

I tried out the installation following the guidelines given by xenomai
documents as per your advice .The details are given below:

Xenomai-2.4.10 patched on linux 2.6.29.4,host OS-fedora 11

while patching  xenomai gave arch as x86(Is this correct for my server???)

I used the following options following options in the kernel config

1.Processor -Pentium Pro(Strangely newer xeon option  doesnt work ..kernel
doesnt boot...tried several times)

2.ACPI-Processor disabled

3.APM disabled

4.CPU frequency scaling disabled

5.Check for P4 thermal throttling interrupt disabled.(If enabled gives a
error while making kernel)

5.rest all default options.

After installing i could boot inside xenomai kernel but when i ran xeno-test
program ,got worst case latency of around 88 us which is not good enough.

some other points:

1.Grepping dmesg showed no message "SMI chipset found"(SMI detection was
enabled), so my platform surely does not have SMI chipset(Is this assumption
correct????).

2.There are 4 UHCI USB and 2 EHCI USB embedded controllers in the server.But
anyway the UHCI and EHCI drivers were loaded.

I dont know how to proceed next.Would be very helpful if you could guide me
on where things could be going wrong.

Thanking you,

With Regards,

S Saravanan

If you do not know that, we can not know it for you.

Well, this deserves to be investigated. You can get help by enabling
early printk.

The important part of my message is that ACPI should be enabled, with
only ACPI-Processor disabled.

Two things:
- first the dmesg buffer may be too small for kernels with lots of cpus
and USB devices plugged, so you do not get all the messages, better use
a serial console, or network console.
- the fact that you do not see the SMI chipset found may mean that your
chipset is not supported in Xenomai's smi module. To enable its
detection, you have to add the proper PCI ids to the ksrc/arch/x86/smi.c
file.

First of all Thank you stefan for also helping out.Today I was going through
the various options in the system set up of the server when I stumbled upon
power management option.It was set to Active Power Controller.I set it to OS
control and when i booted into xenomai and run xeno test got worst case
latency of around 8 us which is decent .So all this while i guess the ACPI
options were not being used.

This apart i think ideally latency should be around 3 us.What settings can i
change further.

Currently i am not enabling Low Latency Desktop option.Should I???

And Stefan here are the outputs you requested.I have also attached them in
text files.

We also need to find out why xeon option in processor is not working.Anyway
thanks Gilles and Stefan

I wont be able to test further until next week.So will post next week
