[Xen-devel] Xen PV: Sample new PV driver for buffer sharing between domains

[Omkar Bolla <omkar.bolla@xxxxxxxxxxxxxxxxxxx>]

Hi,

I am using Debian as Domain-0 and Debian as Domain-U on Hikey960 platform(ARMv8) and using Xen-4.8 stable release. Here I want to create a PV frontend and backend to share memory between Domain-0 and Domain-U. 

I used below link to create frontend and backend,

https://fnordig.de/2016/12/02/xen-a-backend-frontend-driver-example/

But I am facing below errors while adding device vdevb to xenstore. 

Below errors I am getting from xenbus_switch_state().

vdevb vdevb-0: failed to write error node for device/vdevb/0 (13 writing new state)

Please suggest me, How to create PV drivers.

Thanks,

Omkar B
