| Hi Stefano, sorry if i am so late but my schedule was full this week. I am currently preparing a presentation for an event here in Italy and i had no time to check even my emails.

did you manage to make any progress on the number of cores exposed by the model?
I am still not using the psci and the XEN console says that he is bringing up all the 4 CPUs. 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).
I will try to give it a look this weekend but i am not sure to have the time to make e fix soon. 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.
FYI I added some more information on this project here:http://marc.info/?l=xen-devel&m=149074542307880
Thank you for all the information. Unfortunately I have not considered all of my personal deadlines before attempting to approach this project. It was my mistake. Anyway I will try with all my strength to fill up the application this weekend and try to submit it anyway. I like the Xen project, and even if I will not be chosen for this task, surely I will continue to support and follow it diligently.

Hello Luca,

I tried also this method but i had the same error. So i came up with the
idea of removing the
psci method from the configure and also from the dtsi file that i have
changed.
I guess you are using only 1 core in this case. Am I right?
No, i am using 4 cores, with —cores option and i think that i am using actually 4 cores
because on the model “control panel” i have 4 green triangles which ones of them should
represent the number of cores and their status.
It is only my opinion so, please, tell me if i am wrong.
With this configuration the model booted up correctly, even if the
process took about 10 minutes.
Just for my personal knowledge: it is normal that the boot is very slow?
Is the rootfs that i’m using?
Booting a full distro on the model can be slow. Usually I write my own initscript to start the necessary daemon and skip systemd.
42sh> cat /root/init.sh
set -x
mount -t proc proc /proc
mount -t devtmpfs dev /dev
export HOME=/root
rm -rf /var/run/xenstore
rm -rf /var/run/xen
/etc/init.d/xencommons start
exec /bin/bash
-------------------
And I pass init=/root/init.sh on the Linux kernel command line.
That helped a lot, thank you.
Cheers,
