[Xen-devel] [PATCH v9 0/9] Introduce HVM without dm and new boot ABI

This are the remaining patches of the HVMlite series. They have been 
successfully tested on the following hardware:

 - Intel Core i3-5010U.
 - AMD Opteron 4184.

With both hap=0 and hap=1 in the configuration file. I've been able to boot
a SMP guest in this mode with a virtual hard drive and a virtual network
card, all working fine AFAICT. Migration/save/restore has also been tested 
with a SMP guest using the FreeBSD kernel provided below.

The series has been compile tested on arm32.

The series can also be found in the following git repo:

git://xenbits.xen.org/people/royger/xen.git branch hvm_without_dm_v9

And for the FreeBSD part:

git://xenbits.xen.org/people/royger/freebsd.git branch new_entry_point_v5

In case someone wants to give it a try, I've uploaded a FreeBSD kernel that
should work when booted into this mode:


This FreeBSD kernel starts the APs in long mode. There are examples for 
starting the APs in other modes in the sys/x86/xen/pv.c file.

The config file that I've used is:



name = "freebsd"

Of course if you have a FreeBSD disk already setup it can also be added to
the configuration file, and the following line can be used to point FreeBSD
to the disk:


As usual, each patch has it's own changelog.
