testing hypercall from windows - what''s the most basic call I can make to test
I''m tinkering with some code to be able to talk to the hypervisor from
Windows, with the ultimate aim to get a usable xenbus.
So far I''ve created a driver for the Xen PCI ''device'', and (hopefully)
mapped the hypercall space given by the CPUID call...
What is the simplest hypercall I can make to get an answer from the
hypervisor to tell me that it''s
