[Xen-devel] Is there any range of XEN hypercalls reserved for vendor specific

[veerasena reddy <veeruyours@xxxxxxxxx>]

Hi,

We are looking to add new hypercalls to XEN hypervisor 3.4.3 for one of projects.
Is there any range of hypercall numbers reserved which can be used to add new hypercalls any third-party developer other than Xen.
Because if we now add a new hypercall (say, with number #60), and in future XEN releases a official patch which also adds a new hypercall with same number (#60), there will be a clash.

So, could you please advice which of the hypercall numbers (may be a range) can be safely used for our customizations.

Thanks & Regards,
VSR.
