Sample backend/frontend driver

[AshishKumar Mishra <ashish.emailaddress@xxxxxxxxx>]

Hi All ,

I am starting with Xen for internal evaluation.

- Can team share some input / pointers to understand the 

   architecture / template to understand the frontend or backend driver of xen

- I had cloned the latest version of xen code ( which is 4.13 )

  But could not find any usage of

  xenbus_register_frontend / xenbus_register_backend

          $ grep -nisr xen-4.13.1/* -e 'xenbus_register_frontend'  ( No result )
          $ grep -nisr xen-4.13.1/* -e 'xenbus_register_backend' ( No result )

  I was going through https://wiki.xen.org/wiki/Introduction_to_Xen_3.x

  to understand the binding of the frontend / backend driver

 

 

- My aim was to understand an existing code for frontend & backend

  and write an hello-world kind of module.

 

Please do let me know if I am missing anything here or doing completely wrong here .

Thanks ,

Ashish .
