Preempt-RT will be mainlined into stock linux fairly soon now so its just becomes a kernel config option but I doubt real time kernels will ever be standard for common desktop distributions as they typically have lower performance (excluding latency) than non RT kernels > > > >> -----Original Message----- >> From: Sebastian Kuzminsky [mailto:s...@highlab.com] >> Sent: March-16-16 8:29 AM >> To: Enhanced Machine Controller (EMC) >> Subject: Re: [Emc-users] Linuxcnc on arm >> >> >> On 03/16/2016 08:25 AM, W.
