This is also okay, but problem here is I am using 4.8 stable  xen because it  is working on Hkey960(ArmV8)

This is because you can't bring up secondary CPUs on the Hikey with Xen 4.11 [1], right? It would be nice to find where the bug was introduced because Xen 4.8 is out of support and does not contain the latest fixes (such as Meltdown/Spectre).

Is there any other way to share buffer dynamically?
You would have to write your own PV drivers or port the series to Xen 4.8.
