Below is an updated version of my patch to valgrind to allow it to
understand privcmd ioctls and some hypercalls. I have implemented a
bunch more hypercalls, including all those I saw when creating a pv or
hvm domain with my particular configuration.
As before I bailed on the normal valgrind policy of duplicating the
interface headers so usage is still:
./configure --with-xen=/path/to/headers
The path needs to be to an installed set of xen headers, such that
"#include <xen/xen.h>" is valid e.g. dist/install/usr/include in your
built Xen tree or /usr/include or something equivalent (e.g. libxen-dev
installed under Debian etc.)
Not extensively tested, caveat emptor etc etc.
