Anyone can provide a detailed code example of how to use this RPC protocol, to communicate from the Ax cores/Linux to SCFW or the cores that own a resource I want, to get access to that resource...?

Can I do / use The Resource Management (RM) API"  this way, through RPC ..?

Does this only work at kernel level, and then needs a user-space client, like scfw_cli app...?

I don't understand how scfw_cli app works, can it invoke Any of those SCFW APi calls ..? Can it do the RM stuff...?  Example please ..??

Yeah, no offensive, but I have to say, it is really pity that the document is too poor for this scfw api.

It seems there are so many pdf/html, but just a full list plain text, without any useful info

You could download the SCFW porting kit from here. There is source code and the documentation in the porting kit.

e.g. SCFW Porting Kit​ 1.14.0

Yes, I got it, and seems you have to modify Linux kernel to allow user-space app to use the SC services ...

Also no clear example how to, for example, ask resource owner to use it from another domain .?
