[Xenomai] Xenomai v.3.0.7 on Ubuntu 18.04 and kernel 4.9.90

[Xenomai] Xenomai v.3.0.7 on Ubuntu 18.04 and kernel 4.9.90

[Wojciech Domski]

Hi!

I am trying to set up Xenomai v.3.0.7 on Ubuntu 18.04 with kernel 4.9.90.

I have downloaded Xenomai from git and checked out the v.3.0.7 tag for
stable version of Xenomai.

To set up the new kernel I have copied the configuration from currently
running version (4.15.0-36-generic). Also I am preparing the kernel with
following

sudo xenomai/scripts/prepare-kernel.sh --linux=/usr/src/linux
--arch=x86_64 --ipipe=/usr/src/ipipe-core-4.9.90-x86-6.patch

In kernel configuration I have turned off the following:

Power management and ACPI options -> ACPI (Advanced Configuration and
Power Interface) Support -> Processor
Power management and ACPI options -> CPU Frequency scaling -> CPU
Frequency scaling
Power management and ACPI options -> CPU Idle -> CPU idle PM support

Unfortunately, I could not turn off page migration since it is build in
the kernel and "hard fixing" it in the kernel configuration file did not
seemed to the best idea.

After that I have build the kernel with following:

sudo make-kpkg --initrd --append-to-version=-xenomai-3.0.7 -j8
kernel-image kernel-headers modules

and that

sudo dpkg -i linux-image-*.deb
sudo dpkg -i linux-headers-*.deb
sudo update-initramfs -c -k "4.9.90-xenomai-3.0.7"

What I am facing right now is the following problem. When I boot up the
PC freezes on "Loading initial ramdisk ...". Did I missed something? It
does not seem like it is Xenomai related problem since there is an issue
during mounting the temporary file system.

Best regards,

[Wojciech Domski]

Hi!

I did additional test to rule out that Xenomai is the issue.

I have compiled kernel 4.9.90 without Xenomai and it turns out that it
works. Having this in mind what could cause problem on Xenomai side?

If needed I will add additional information to trace the problem.

Posting the config may help.  Can you get any early printks?

[Wojciech Domski]

I will post the kernel config file shortly and get back to you.

As for the prints, no, there is nothing only those two lines:

Loading Linux 4.9.90-xenomai-3.0.7 ...
Loading initial ramdisk ...
_ (here is the cursor)

Re: [Xenomai] Xenomai v.3.0.7 on Ubuntu 18.04 and kernel 4.9.90

[Wojciech Domski]

Here are kernel configurations files:

https://pastebin.com/zuucW3WW (for clean 4.9.90)

https://pastebin.com/AvD9T9Lx (for 4.9.90 with xenomai 3.0.7)

I have also checked if there is anything in /var/log/kern.log. Beside
normal kernel's logs there is nothing for the Xenomai flavoured version.
It seems about right because it is stuck at "Loading initial ramdisk".

Hi,

You may want to disable CONFIG_MAXSMP, some people reported similar 
issues with this option enabled.

Re: [Xenomai] Xenomai v.3.0.7 on Ubuntu 18.04 and kernel 4.9.90

[Wojciech Domski]

I have conducted some additional tests and it seems that the patch is
the problem itself.

To confirm that the kernel is working properly I have compiled it as it
is using configuration from Ubuntu stock kernel. However, that doesn't
really say that everything is ok. After that I have configured the
kernel as I did for Xenomai but without patching it in the first place.
The configuration included disabling frequency scaling and etc. (based
on the tips in
https://gitlab.denx.de/Xenomai/xenomai/wikis/Configuring_For_X86_Based_Dual_Kernels).
After compilation of the kernel I can confirm that it works. I can boot
into the system.

I'm assuming that patching is causing booting issues. That said, do you
have any advice how to proceed further?

Re: [Xenomai] Xenomai v.3.0.7 on Ubuntu 18.04 and kernel 4.9.90

[Alec Ari]

I would suggest building the kernel without an initial ramdisk, and using only the vmlinuz image itself. Adding earlyprintk=vga to the kernel params may help as well to get some valuable input.

Disable initramfs support in your kernel config, don't use dracut or anything, then try again.
