Re: [Xenomai] thread executing udd_register_device() is not rescheduled again

Hi Philippe and all, While I may have too many questions from my previous email, I think what I really need is someone to confirm my question #2 where calling udd_register_device() (in kernel space of course) is inappropriate in Xenomai when initiating the process is from a user space via an

Hi Pintu, I just started doing some work recently with the RPI3 to see how Xenomai performs, but I haven't made it too far at the moment. How did you tune the system? -Greg On Sun, Jun 17, 2018 at 10:07 AM, Pintu Kumar wrote: > Dear Greg, > > Do you have any comment about this? > On Wed,

Are there still plans to have a ipipe patch for the CIP kernel? I think this was brought up at the last meet up? Maybe the bigger question (which is a lot more work) is do we plan on maintaining ipipe for 4.4, 4.9 and older? -Greg On Mon, Jun 18, 2018 at 8:52 AM, Radu Rendec wrote: > Hi all,
