[Adeos-main] Proprietary RTOS on top of Adeos

[Remi Lefevre]

Hello,

At first, congratulations for this very interesting project.

I have a simple question : does the Adeos licence and integration with
Linux allows to port a proprietary RTOS on top of Adeos without
setting it in GPL (as a whole or as a skin) ?
I'm conscious this is not the aim of this project, but convincing
company politics may take some time...

Best regards,
Rémi

Everything which fiddles with the internals of the Linux kernel has to 
be seen as extension of GPL software, thus falls under the GPL, too. For 
this reason, Adeos is also licenced under the GPL, and so are the kernel 
parts of Xenomai and its skins. Normally, an RTOS emulation skin 
consists of a kernel part and userspace libraries. If you follow this 
path for your proprietary RTOS at least the kernel part must be GPL 
compliant.

Neither Adeos or any kernel-based part of Xenomai were meant, are
currently meant or will ever be meant to be "GPL barriers".
Additionally, we do use and depend on Linux kernel code, including
fairly internal one, and as such we do fully comply with the kernel license.
