building xen activated arm kernel for Tegra k1

Dear all,
 I just get my Jetson Tegra k1 and was planning to try out Xen on it. It
has a 3.10 kernel with Ubuntu 14.04. Also I have downloaded kernel source.
I am quite new on kernel building but I have done before via menuconfig for
additional modules. My question is; as I have already source and .config
from Nvidia do you think below guide would be enough for me to rebuild
kernel for arm?

http://wiki.xen.org/wiki/Mainline_Linux_Kernel_Configs

Anyway tonight I will give a shot, it is Friday!:)

Thank you for your help
Burak

This is a good start for building the kernel. Although, some options may 
not work/exist on ARM such as:

- *X86* of course :)
- CONFIG_*_PCI_*
- CONFIG_PARAVIRT_*
- CONFIG_HYPERVISOR_GUEST
- all tmem support (I don't even know if someone tried to use it on ARM)
- CONFIG_ACPI

I will see if we can update this page during the next document day for ARM.

You can also give a look to the xen wiki page about ARM. It will give 
you some tips about building Xen and debugging guest kernel.

http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions

If something is missing or you have an issue that you don't understand, 
just let us know.

Hey Julien,
 Thank you for the answer, my first resource was your video for the arm
platform. you have done great job guys! my target also is running
Opennebula on Jetson top of Xen it has cortex A15 as Versatile but a bit
more cheaper:) Looks like all those configs by default 'y' in Nvidia
config. I spent some time yesterday on wiki. This week I will try to run
Xen on it and come back if I will have some trouble.

Thank you again
Have a nice weekend
Burak

Hello Burak,
if you come up with a clean set of instructions on how to run Xen on
Jetson Tegra k1, it would be nice if you could write them down on the
wiki.
Cheers,

Stefano
