Re: [XenARM] State of PV Xen on ARM

[Simon Sturm <Simon.Sturm@xxxxxxxxx>]

Hi,

What is actually the current and future development plan of the PV version of 
Xen on ARM?
I guess that this work will not go upstream to the "official" Xen on ARM 
(originally intended for processors with virtualization extensions) soon and 
maybe never.

Am I right with this assumption?


Thanks,

Simon

Xen on ARM with virtualization extensions basically needs a Cortex-A15 
processor.  It currently runs on the Arndale board and Samsung Chromebooks.
