Re: [Machinekit] How does machinekit test to see if it is running on a rt-preempt kernel?

[schoone...@gmail.com]

That is one way to deal with it. rtapi_compat.c first checks the env var FLAVOR, before trying to determine other ways Run these tests from a terminal and let us know what result you get cat /sys/kernel/realtime     (should return 1) cat /boot/config-<kernel-version>  | grep CONFIG_PREEMPT_RT_FULL=yes  ( should return CONFIG_PREEMPT_RT_FULL=yes) uname -a | grep 'PREEMPT RT'  ( should  return PREEMPT RT - but we already know it won't) There is something screwy about the 4.19 kernel and rt.  I stopped using the Debian rt-amd64 version and reverted to 4.18 because of problems On 19/02/19 04:44, mugginsac wrote: Robert just furnished a new test image. It definitely has an rt-preempt kernel, when I exported FLAVOR=rt-preempt, it ran machinekit. However, before I exported FLAVOR=rt-preempt, machinekit tried to run the posix realtime stuff (term of art). So, the question is how does machinekit try to determine the nature of the kernel that it is running on? Robert asked if we should just set FLAVOR=rt-preempt in the environment when we create the uSD. Is that acceptable? -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
