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
