Re: [XenARM] Questions about XENARM

[서상범 <sbuk.suh@xxxxxxxxxxx>]

Hi Josh,

I have merged Xen ARM hypervisor using ARM v7 core only while I have prepared the archieved Xen ARM hypervisor for older ARM core after careful thoughts on performance issues and ARM multicore support architecture.

I will maintain Xen hypervisor dependent on ARM CPU architecture in particular and will encourage submissions.
I will address this for more detauil at Xen Summit Asia 2, 3 Nomvember 2011 in Seoul Korea.

Regarding hypercalls syntax have been common to both Xen ARM and Xen mainline though the previous Xen ARM has more hypercalls for light weight access control within Xen ARM before the merging and has more semantics in hypercalls.
 
As for PV Linux, the patch on top of vanila Linux has been available but it is for Xen ARM version before the merge. 
Due to efficiency and lowest CPU and memory overheads of the existing Xen ARM version before the merge with Xen mainline, compared to other solutions supporting multiple VMs such as VMWare mobile and Ok labs L4 micro kernel based one, the patch for PV Lunux on Xen ARM merged with Xen mainline is required to be developed.

Thank you,

Sang bum Suh

Hi All,

I am new to XenARM and have 3 questions about this project:

1)  Is this project merged into xen's mainline?  How other guys contribute codes for it?

2)  Is there a hypervisor API doc for guest OS?

3)  I couldn't find PV-Linux for XenARM on wiki, am wondering whether there is a entire tarball including hypervisor, Guest-Linux and guest OS. 

Thanks 

josh zhao
