Re: [Xen-devel] [GSoC] Xen on ARM: create multiple guests from device tree

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hello Luca,

did you manage to make any progress on the number of cores exposed by the model?

Thank you for the Makefile patch! If you have time, I encourage you to
fix one of the other small outstanding bugs, for example XEN-20 or
XEN-11 (just the ability to load a Dom0 kernel bigger than 128MB or just
the ability to parse the new image_size field introduced in Linux 3.17).

Finally, I would like to remind you of the upcoming deadline for
applications submissions, which is the 3rd of April for GSoC, see:

http://marc.info/?l=xen-devel&m=149071502330534

The GSoC application system is
https://summerofcode.withgoogle.com/get-started/.

Please give a look at the Xen Project application template here:

https://wiki.xenproject.org/wiki/GSoC_Student_Application_Template

It also includes an "Implementation Plan", where you have the chance to
explain the implementation plan for the project you would like to apply
for.

Thanks,

Stefano
