Hi,

I run into a build error when compiling ipipe.c as follows:

  CC      arch/arm/kernel/ipipe.o
 arch/arm/kernel/ipipe.c: In function '__ipipe_grab_irq':
arch/arm/kernel/ipipe.c:421: error: implicit declaration of function '__ipipe_mach_irq_mux_p'
make[1]: *** [arch/arm/kernel/ipipe.o] Error 1
make: *** [arch/arm/kernel] Error 2

Kernel: 2.6.26
Adeos patch:  adeos-ipipe-2.6.26-arm-1.12-00.patch
Xenomai: 2.4.7, and 2.4.8
Tool chain: Denx 4.2 for arm
Target CPU: iMX25

googling around find no such reports.

Any help is highly appreciated.

Best regards,
David

Well it looks like __ipipe_mach_irq_mux_p is not implemented for your
processor. You will find documentation on what it should do on the
I-pipe on ARM guide.

http://www.xenomai.org/index.php/I-pipe:ArmPorting

Normally, this code goes in arch/arm/mach-imx/include/mach/irqs.h, but
the code I see here is not conditional, so should be used if IMX25 is
part of the IMX family. However, I do not see IMX25 in the list of
supported processors. Where did you get support for that processor from?
