Hi,
I am looking to add a new hypercall to XEN-3.4.3 and invoke this new
hypercall very often (may be 50 to 500 thousands of times a sec) from a HVM
guest.
I would like to see the cost of this to tradeoff with performance.
Could you please advice if there are tools for this or any other method that
i can use?
Thanks in advance.
Regards,
VSR.
