Enable Xenomai on i.MX Platform

Enable Xenomai on i.MX Platform

[Xiaodong Zhang]

Hi Xenomai,

 I ported ipipe patch and enable Xenomai 3.1 on i.MX Platform (i.MX6 series
and i.MX8M based on Yocto L4.19.35 1.1.0 GA release), the below link will
give more information.

https://community.nxp.com/docs/DOC-347373

https://community.nxp.com/docs/DOC-345893

Later I and my colleague will focus on fix bugs, optimize real-time
performance, add more RTDM i.MX drivers and improve system stability for
i.MX6/8 platform.

BTW, I don’t see ipipe 5.4 patch, and can you tell me the plan when enable
ipipe on Linux 5.4 kernel?

 

 

Thanks & Best Regards,

Zhang Xiao Dong (张晓东)

Are your changes also coming up stream?

Currently the plan is to switch from using the ipipe to dovetail for
5.4.  With dovetail we shouldn't have to maintain separate repos per
architecture.

Hi Greg,
   Thank you for your feedback. I also have plan to upload to i.MX next release (maybe Yocto L5.4.47) which will support i.MX8MP(the first i.MX SOC has NPU, ISP and TSN). 
I find some information about Dovetail in EVL project(https://evlproject.org/dovetail/ ), and do you mean Xenomai will reuse dovetail of EVL project for Linux Kernel 5 or future version ?

Yes, the plan at the moment is to reuse dovetail and port Xenomai as
the realtime core.  This will hopefully help with reducing the amount
of maintenance required.
