I successfully compiled the 3.8.13 kernel with xenomai on debian stretch. I am using the same xenomai userspace libs as on jessie (2.6.3) and i compiled the latest machinekit from source directly on the BBB. (Note: you will need a swap device during compilation, I used a swap file on the SD)
Interestingly I get the same speed and a really responsive GUI with this kernel. The same file that loads within 4 minutes on the exact same hardware and the same SD card using the 4.19.37 kernel does load now within 20s! The same performance as my old jessie box. So my recommendation is kernel 3.8.13 ;) I do not know why I see such a massive performance issue when using the 4.19 kernel but for now I will stay with the 3.8.13 kernel. If anyone has an idea what might cause the performance issue I would be happy to learn about it :) Regards, Simon -- 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.
