Hi, I wanted to ask how to enable serial communication in Xenomai. When
compiling the kernel, what parameters should I set?

Dear Xenomai people,
is the configuration option CONFIG_SYSFS_DEPRECATED necessary for Xenomai
working correctly?
Kind regards

I recently rebuilt my kernel and I seem to be running into some problems
that I previously encountered with xenomai. Unforutnately, I can't seem to
fix them.
When I load my application (which runs at Barrett WAM), I get the following
messages in my kernel log.

No (unless there is an indirect dependency I'm not aware of), Xenomai
does not export any data through sysfs. A truckload o

Certainly true, but that's the software you control so you can make it
behave itself.

Sorry for the delayed reply! I was a bit under the weather this weekend.
I think that you folks have hit on my alternate hypothesis: that I am doing
something in my program in the real-time thread that is causing problems.
It's a little weird, because I am linking against libbarrett. I wrote a

Yeah, I saw that. I may need to back that out and put in the open source
driver.

I figured it out. One of my threads was not cleanly exiting and was
screwing up the OS. I more carefully cleaned up at exit and life is good.
Thanks folks!

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
When configuring kernel (4.19.144 arm) through menuconfig, I get the
following warning:

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.

It's strange that the frequency of the CPU is not constant if I both

Oh, disabling Continuous Memory Allocation makes Page migration item to
disappear, but it does not make sense as CMA is bellow Page migration
option lol. But at least it worked.

Hello,
I am trying to make a hard real-time application on Xenomai
(dual-kernel configuration). Here are some questions.
1. To fully utilize the realtime capability of Xenomai, should I apply
xenomai to all the associated application libraries?
For example, if I run the
