[Xenomai-help] Processor type for installation

[-- Attachment #1: Type: text/plain, Size: 2568 bytes --]

Dear all

I've been trying to install Xenomai but I haven't been able to do it
right.  After being able of building and installin the kernel and Xenomai,
I tried to run the example program trivial-periodic, I got the following
error

/usr/src/xenomai-2.6/examples/native$ ./trivial-periodic
Xenomai: incompatible feature set
(userland requires "tsc fastsynch", kernel provides "sep fastsynch smp",
missing="tsc").

I read that the reason for this is that I didn't configure correctly the
processor family (with xconfig). Is that the reason? Also, I've been trying
to know which option should I choose (I chose CONFIG_M586 at the
beggining), but I don't know were to get that information. The CPU info
goes as follows:

We do not know which kernel version, which xenomai version, which adeos
I-pipe version.

So, you have a core i7, anything newer than "pentium pro" (an older than
ten years old architecture) should do, but better select the processor
you actually have or the nearest substitute: so, assuming you are
compiling a 2.6.38 kernel, "core 2/newer xeon" should do. Also note that
a core i7 is able to run in 64 bits mode, so running it in 32 bits mode
is a bit a pity.

Sorry I didn't write the kernel + xenomai specifications. I'm using
linux-2.6.38.8 and xenomai 2.6. About Adeos and I-pipe, should I do any
kind of installation of the before installing Xenomai??

Regarding the processor family, i selected 'core 2/newer xeon', and tried
to build a 64-bits kernel. But when I tried to boot the new patched kernel,
I got the following error and get stacked in the booting:

[     0.051013] ..MP_BIOS bug: 8254 timer not conncted to IO-APIC
[     2.338200] EXT3-fs (sda1) error: couldn't mount because of unsupported
optional features (240)
[     2.362370] EXT3-fs (sda1) error: couldn't mount because of unsupported
optional features (240)

[     2.400612] request_module: runaway loop modprobebinfmt-464c
[     2.400755] request_module: runaway loop modprobebinfmt-464c

I don't know if I did something wrong in the installation process. These
were my steps:

1.   sudo git clone http://git.xenomai.org/xenomai-2.6.git/usr/src/xenomai-2.6

2.   /usr/src/xenomai-2.6/scripts/prepare-kernel.sh
--linux=/home/corbys/linux-2.6.38.8/
--adeos=/usr/src/xenomai-2.6/ksrc/arch/x86/patches/adeos-ipipe-2.6.38.8-x86-2.11-01.patch
--arch=x86_64

3.   cd ~/linux-2.6.38.8/

4.   make ARCH=x86 xconfig

   #I had to put ARCH=x86 because otherwise it didn't let me select
CONFIG_64BIT

   #Set 64-bits option
   * CONFIG_64BIT

   #Select the processor family
   * CONFIG_MCORE2

   #Be sure the following kernel settings were unmarked:
    * CONFIG_CPU_FREQ
    * CONFIG_APM
    * CONFIG_ACPI_PROCESSOR
    * CONFIG_INTEL_IDLE
    * CONFIG_PCI_MSI

5.   make ARCH=x86 bzImage modules

6.   mkdir ~/build/linux-2.6.38.8 && cd ~/build/linux-2.6.38.8

7.   /usr/src/xenomai-2.6/configure

8.   sudo make install

9.   sudo cp /home/corbys/linux-2.6.38.8/arch/x86/boot/bzImage
/boot/vmlinuz-2.6.38.8-xenomai-2.6

10.
   sudo addgroup xenomai
    sudo usermod -a -G xenomai user1
    sudo usermod -a -G xenomai user2

11. sudo update-grub

12. Restart computer and boot in new kernel

Your kernel is probably not configured correctly. Something is missing
in the filesystems configuration such as ext4 support.

Also note that you need to have a 64 bits root filesystem if you want to
run xenomai on a 64 bits kernel.
