Thanks Cern! I simply took out that chunk of code and everything seems to
work.

You are not the only one bitten. There is/was discussion in Machinekit Matrix

Personally, I consider it premature and think that the program should cross 
that bridge when it comes at it and not when everything it sees is flat land. 
So I would remove it.

This seems to be the source of the problem:
https://github.com/machinekit/machinekit-hal/blob/9fca994e08e3f8384498e78ea8e8baa1c899e4db/src/rtapi/rtapi_app.cc#L1457

The system call iopl seems to be returning an error:
http://man7.org/linux/man-pages/man2/iopl.2.html

[Machinekit] problems with realtime kernel on Beaglebone AI

2020-05-01 Thread John Allwine 
I posted this on the Beaglebone forums 
 
and figured someone here may be able to help too:

I'm trying to use a real time kernel on the Beaglebone AI to get MachineKit 
running. I'm able to run MachineKit on a non-rt kernel (4.14.108-ti-r113), 
but when I update to the latest ti-rt kernel (4.14.108-ti-rt-r134), I get 
an error: 

user cannot gain I/O privileges - forgot 'sudo make setuid'?

In dmesg, I see this:
[  811.654246] warning: process `rtapi:0' used the deprecated sysctl system 
call with 8.1.2.

Robert Nelson offered to tweak the rt kernel config to support that call. 
Is that what needs to happen?
