[Xenomai-help] Xenomai 2.5.6 and 2.6.38.8 kernel

[Xenomai-help] Xenomai 2.5.6 and 2.6.38.8 kernel

[Anders Blomdell]

When trying to compile 2.5.6 with adeos-ipipe-2.6.38.8-x86-2.10-00.patch, I get
the following error:

  CC      arch/x86/xenomai/hal_32.o
arch/x86/xenomai/hal_32.c: In function ‘rthal_arch_init’:
arch/x86/xenomai/hal_32.c:341:6: error: ‘nmi_watchdog’ undeclared (first use in
this function)
arch/x86/xenomai/hal_32.c:341:6: note: each undeclared identifier is reported
only once for each function it appears in
arch/x86/xenomai/hal_32.c:341:22: error: ‘NMI_IO_APIC’ undeclared (first use in
this function)

Somebody that has a patch to work around this problem?

Regards

Anders Blomdell

Same thing here, I tried to patch linux 2.6.38 with the latest adeos patch (http://download.gna.org/adeos/patches/v2.6/x86/adeos-ipipe-2.6.38.8-x86-2.10-00.patch) but the kernel compilation failed :

Re: [Xenomai-help] Xenomai 2.5.6 and 2.6.38.8 kernel

[Pedro Santana]

My Kernel config file has the NMI watchdog option disabled

Real-time sub-system->Machine->NMI Watchdog->Enable NMI watchdog (unmarked),

but I'm getting the same error during compilation. What should I do in order to
fix this? 

Thanks!

The mail you are replying to contains a patch to solve this issue.

Hi Sir,

I have compiled the Kernel (>20) times now 
and have failed to successfully
implement it.

I desperately need help on it, can you help on it?

In both the cases I am using Linux OS
 Ubuntu 11.04 (kernel 2.6.38.8)
My laptop is Intel Dual 
and any other feature you req to know?

I am fairly new to Linux as well as kernel 
patching so be patient with me and
let me learn.


Case I:
Linux kernel Src tree 2.6.38.8
Xenomai Patch 2.5.6
adeos-ipipe-2.6.38.8-x86-2.10-00.patch

I first faced the error faced above of the 
UNDECLARED VARIABLES
So i declared it myself as 
"int nmi_watchdog =0" and same for the other.

[AS ABOVE]

It got compiled and installed but on boot-up it showed 
" system init fail, code -19
native skin init fail, code -19..." 
and same message for POSIX skin and RTDM skin.

NO IDEA HOW TO SOLVE THIS!!

CASE II:

I tried following Uwue and used a 
previous kernel and same xenomai patch with
the adeos patch for that particular
 kernel but now it is giving me error in the
same function but the error is 
concerning a ")" near the declaration of the
nmi_watchdog and NMI_IO_APIC.


ANY HELP WILL BE APPRECIATED!

Thanks in advance!

You need to apply the patch which was posted in reply to Nicolas' mail.

Read the kernel logs. If you see "Xenomai: Local APIC absent or
disabled", read the TROUBLESHOOTING guide, at the top of Xenomai kernel
sources.

I bet you will have to spend some time on kernelnewbies.org before you
try again using xenomai.
