[Xenomai-help] Xenomai 2.6.5 with Linux 2.6.38.8 kernel

[Daniele Nicolodi]

Hello,

is the Xenomai 2.6.5 supposed to work with Linux 2.6.38.8 kernel and
adeos patch 2.6.38.8-x86-2.10 supposed to work?

The above combination gives me an error compiling
arch/x86/xenomai/hal_32.c in function rthal_arch_init where nmi_watchdog
and NMI_IO_APIC are not defined. Indeed those are not defined anywhere
in the kernel or xenomai source tree.

Thank you. Cheers,

Disable NMI watchdog.

Thanks Gilles for the quick answer, but that's not the problem, NMI
watchdog option is already disabled (and looking at the source code
looks like the error comes from a section of the code that is not
affected by XENO_NMI_DEBUG_LATENCY.

Thank you Philippe. I should follow the mailing list more closely.

Actually, I should have pushed the necessary bits way earlier to the
repo.

Kernel 2.6.38.8 has also renamed current_cpu_data.
See attached patch for fix.
