xen: add PV/PVH kernel entry point
Add the PV/PVH entry point and the low level functions for PVH
early initialization.
Approved by: gibbs
Sponsored by: Citrix Systems R&D
amd64/amd64/genassym.c:
- Add __FreeBSD_version define to assym.s so it can be used for the
Xen notes.
amd64/amd64/locore.S:
- Make bootstack global so it can be used from Xen kernel entry
point.
amd64/amd64/xen-locore.S:
- Add Xen notes to the kernel.
- Add the Xen PV entry point, that is going to call hammer_time_xen.
amd64/include/asmacros.h:
- Add ELFNOTE macros.
i386/xen/xen_machdep.c:
- Define HYPERVISOR_start_info for the XEN i386 PV port, which is
going to be used in some shared code between PV and PVH.
x86/xen/hvm.c:
- Define HYPERVISOR_start_info for the PVH port.
x86/xen/pv.c:
- Introduce hammer_time_xen which is going to perform early setup for
Xen PVH:
- Setup shared Xen variables start_info, shared_info and
xen_store.
- Set guest type.
- Create initial page tables as FreeBSD expects to find them.
- Call into native init function (hammer_time).
xen/xen-os.h:
- Declare HYPERVISOR_start_info.
conf/files.amd64:
- Add amd64/amd64/locore.S and x86/xen/pv.c to the list of files.
