[Xen-devel] [PATCH RESEND v5 0/6] xen/arm: live migration support in arndale board

[Jaeyong Yoo <jaeyong.yoo@xxxxxxxxxxx>]

Note: Resend the patch series since the last one was white-space corrupted.

Hello!
here goes the v5 patch series. The major changes in this version are the 
following:

  1) Save and restore the vcpu-related registers in hvm context. (In patch 1)

  2) Rather than using set_memory_map hypercall use GUEST_RAM_BASE macro as the 
start
     of physical address of guest RAM and just let the hypervisor know the
     maximum memory of guest (In patch 2 and 6)

  3) Use bitmap for temporary saving the dirty pages rather than linked list.
     (In patch 5)


Patch 1 implements hvm save/restore (including vcpu).

Patch 2 implements 'get_maximum_gpfn' hypercall

Patch 3 implements 'modify_returncode' for switching the return value of 
suspend hypercall from domU.

Patch 4 implements base functions for VLPT.

Patch 5 implements dirty-page tracing by using VLPT.

Patch 6 implements the toolstack part for live migration of ARM.

NOTE: In this version, I do not use the p2m walker infrastructure for 
p2m_change_entry_type_global. 
I think I can apply it after Stefanoâs patch is commited. 

Best,
Jaeyong
