[Xen-devel] Hypercall overhead measurement on Xen/ARM

[Jintack Lim <jintack@xxxxxxxxxxxxxxx>]

Hi,

I'm trying to measure number of cycles for hypercalls.
I'm working on ARM v7 and v8.

Xentrace seems to be a right tool to use according to this discussion.
http://lists.xen.org/archives/html/xen-devel/2008-10/msg00480.html

However when I ran it on ARM, it gave an error.
The error is the same as in this discussion in 2014 below.
Xentrace on ARM is not supported?

Are there other tools for this purpose?

Thanks,
Jintack
