Trying to get working LinuxCNC on my Debian Jessie, I did:
- Installed the kernel 4.9 RT through Jessie backport using apt-get/aptitude.
- Restarted my computer and checked
uname -a
containPREEMPT RT
- Installed LinuxCNC by adding the repository and using
apt-get
After that, starting the linuxCNC wizard (by normal clicks through menus) there is a jitter test. My current results are absolutely bad, around 140us.
I wonder if there is any PREEMPTION configuration to enable, or specific way to run an application to get more precise real-time?
Also, how could I check that the process is running real-time?
Note: My computer is an intel E6600
