Thank you for your mail.  In the future, please mail the open-source
list directly with this kind of question.  For one, more people are able
to see it, and you are thus more likely to get a better answer; for two,
there may be other people (now or in the future) who have similar
questions, and having your questions answered in public benefits them as
well.  (Feel free to CC someone you think would be particularly
interested / appropriate, however.)

The ARINC653 scheduler is, as far as I'm aware, used exclusively by
DornerWorks.  I'm only familiar the changes required to the rest of Xen
to get it included.  If you want to know how to use it, your best bet is
to contact one of the developers who worked on the patch:

Josh Holtrop <josh.holtrop@dornerworks.com>
Kathy Hadley <kathy.hadley@dornerworks.com>

Good luck,

Gustavo,

I am assuming that you have already obtained and installed Xen. If not, please look at the Xen website for information on how to do this.

Once you have Xen installed, you can select to use the ARINC653 scheduler by adding the parameter "sched=arinc653" to the end of the boot line used to boot Xen in your GRUB configuration.

In order to set up an ARINC653 schedule from Domain 0 you can make use of a small helper application we have written called arlxctl. This application reads a simple XML file specifying the schedule to set and passes it to the Xen hypervisor from Domain 0 using a hypercall. We are working on making the source code for this application available publicly. For now, I will email it to you separately.

-Josh
