Subject: Xenomai RTnet - Kernel module not loading
Date: Tue, 25 Feb 2020 15:02:28 +0100	[thread overview]
Message-ID: <2eb86315-dc9d-1096-14a7-c3bd2b32a668@b-tu.de> (raw)

Hello all,

I'm a student working on a project comparing different real time OS
approaches. Trying to get RTnet working on a Xenomai Cobalt kernel, but
stuck on loading required kernel modules.

System is running on Ubuntu 18.04 and uses following versions to build
Xenomai kernel:

	Linux Kernel:	4.19.89
	IPIPE:		4.19.89
	Xenomai:	3.1

Kernel is build as described in Xenomai wiki and configured with RTnet
as kernel module.

After installing xenomai kernel and checking the module, everything
looks ok.

> parm:           device_rtskbs:Number of additional global realtime socket buffers per network adapter (uint)

But kernel module can't be loaded.

> $ sudo insmod /lib/modules/4.19.89/kernel/drivers/xenomai/net/stack/rtnet.ko
> insmod: ERROR: could not insert module /lib/modules/4.19.89/kernel/drivers/xenomai/net/stack/rtnet.ko: Function not implemented

Has anybody a hint how to build/ load RTnet kernel module properly?

Thanks
Benji
