[Xenomai-help] xenomai installation

[George Pitich]

I'm pretty much sure this was answered before. If this
is the case could you please refer me to the post?

I'm getting a bit frustrated in my attempts to install
xenomai. I'm following the readme.install from
xenomai-2.4.3 but to no avail. When I execute make
menuconfig after patching the kernel with
prepare-kernel.sh, Real-time sub-system presents me
with:

-- NOTE: Xenomai conflicts with PC speaker support.   
--- (menu Device Drivers/Input device
support/Miscellaneous devices)
--- NOTE: Xenomai needs either X86_LOCAL_APIC enabled
or HPET_TIMER disabled.               │ │
--- (menu Processor type and features)).

None of this options is selectable nor configurable.

By looking into .config, I can see only one xeno
option CONFIG_XENO_GENERIC_STACKPOOL=y. After
compiling the kernel and booting it, xenomai build
looks incomplete. I can't find xenomai LKMs and
therefore can't run testsuite.

I hope it is not because of AMD Athlon cpu on the box.
Many Thanks.

Please do the following in Linux kernel configuration:

disable PC speaker support (you will find it in the Device Drivers/Input
device support/Miscellaneous devices menu).

Enable Local APIC option (if your box has a local APIC, but anything
recent probably has an APIC), or disable HPET timer option (you will find
these options in the Processor type and features menu).

Thanks for the help, now I made a progress and
installed xenomai. I had to compile it with
--enable-x86-tsc=no flag since my testsuite won't run
without a TSC support and I don't know where to
configure this flag during the initial kernel config
process (make menuconfig)? Is it a processor family
specific?

Interestingly enough after a boot, klatency test runs,
but if i stop it (ctrl-c) and run it again it
segfaults:

/usr/xenomai/bin/xeno-load: line 180: 22756
Segmentation fault      $suflag $* $cmdargs

irqbench also won't run:

irqloop: error starting test: Inappropriate ioctl for
device

Regards,

g.

just figured out that it might be because of (ARCH)
uname -i gives unknown?

It depends on the processor you select.

Please select the klatency kernel support as a module, not built-in
kernel. Will fix.
