Re: [XenARM] Which ARM architecture is plannet to be supported.

[서상범 <sbuk.suh@xxxxxxxxxxx>]

Hi,

Xen ARM source code based on ARM v7 with multicore support has recently been 
changed 
so that CPU architecture independent code of x86 based Xen mainline will be 
shared 
I have a plan to support the future Cortex A15 virtualization extension.

On the other hand, I have released Xen ARM hypervisor source code since 2008, 
which includes ARM v5, v6 and the para-virtualized ARM Linux kernel patch.
These source code can be found at the Xen ARM wiki of Xen.org.

Considering performance issues in terms of CPU overhead, context switching 
overhead due to cache architecture and 
CPU architecture such as multicore support issues,
I think that it is better for ARM v5 and v6 Xen ARM hypervisor source code to 
not be merged with the Xen mainline.

I suggest to use the archieved Xen ARM hypervisor for ARM v5 and v6 at the Xen 
ARM wiki.

Thank you,

Sang-bum

Title  : [XenARM] Which ARM architecture is plannet to be supported.

Hello,

Just out of curiosity is this project only planning on supporting the ARMv7 
architecture or are ARMv5 and v6 still part of the plan?

Thanks.

JC
