Xen devel - Nov 2013 - [PATCH v5 0/6] xen/arm: live migration support in arndale board

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 Stefano''s patch is commited. 

 

Best,

Jaeyong

I''m afraid that at leas the first two patches (and probably all of
them)
are whitespace corrupted.

git send-email is quite good at avoid these sorts of things, see
http://wiki.xen.org/wiki/Submitting_Xen_Patches#Git_send-email

It also has the affect of chaining the patches together into a thread,
which is very useful for reviewers and committers to be sure they are
getting a consistent set of patches etc.
