SUMMARY = "Xen hypervisor"
DESCRIPTION = "The Xen hypervisor"
# This recipe is for just the Xen hypervisor.
# Separate recipes are used to build Xen and its components:
# this allows for varying the target architecture or toolchain used
# to build the different components. eg. 32-bit tools and a 64-bit hypervisor.
# The Xen hypervisor has a narrower compatible platform range than the Xen tools

# so do_deploy must run after do_populate_sysroot and after do_compile is
# also needed for when having rm_work and bitbake needs to re-run do_deploy,
