Xen devel - Apr 2006 - [RFC][PATCH] Hypercalls from HVM guests (2/2)

A sample test module for the HVM hypercall interface.

Signed-off-by: Steve Ofsthun <sofsthun@virtualiron.com>

1) To use, put these files in a directory by themselves.
2) Edit the Makefile:
    Set XEN_ROOT to a populated xen tree.
    Set LINUX_ROOT to a linux build tree for your HVM domU kernel.
3) make

The output should be test.ko.  You should be able to load this
module on an HVM guest using:

# insmod test.ko

Module output on the console should appear like:

hypercall_page @ ffffffffa020f000
xen_features[0].writable_page_tables = 1
xen_features[0].writable_descriptor_tables = 0
xen_features[0].auto_translated_physmap = 1
xen_features[0].supervisor_mode_kernel = 0
xen_features[0].pae_pgdir_above_4gb = 1

Enjoy,
Steve
