Hey guys,
I'm running the new Xenomai 2.6.2.1 with 3.5.7 Kernel on a x86 machine.
I tried several kernel configurations, but I haven't found the right one yet.
The PC (ADLD25PC) uses a PEAK-Systems PCIE/104 CAN interface and two serialport
devices.
I have selected the CAN driver and 16550A driver as kernel modules.
With kernel configuration "-xenomai4" the serial and can devices works, but
there are only 2 CPUs detected - so the hyperthreading cores arn't detected.
And I get a message during bootup "BIOS bug, no explicit IRQ entries, using default
mptable. (tell your hw vendor)."
This is my "best" solution so far - CONFIG_ACPI is completely disabled.
In "-xenomai5" configuration is ACPI enabled as you can see in the attached
kernel configs.
The mptable message disappears, 4 cores are detected, but serial and can device
IRQs get disabled.
The can interface and a usb hub get IRQ 19 - thats solvable for me, but the
serialport on IRQ 4 gets disabled and I don't know why. (lspci -v log is also
attached)
Could you point me in a direction how to combine the advantages of the two
configurations?
Thank you,
Christopher

It would be interesting to have the kernel boot logs too.
Sorry, here they are.
I tested these two versions again and recognised that in "-xenomai5" the
CAN interface is working.. so there is "just" the serialport issue (IRQ
4 disabled) left. Everything else seems to work correct.
Please also post the result of
cat /proc/interrupts
and
cat /proc/xenomai/irq
But I guess the problem you have is that the IRQ 4 is shared.
I attached the logs of /proc/interrupts and /proc/xenomai/irq before and
after accessing the serial device
Yes looks like IRQ 4 is shared, but I can't find out which device also
uses IRQ 4.
