ARINC-653 API

[张文杰]

Hi Joel, I am very sorry for making you mistake. That AIR use PMK instand of
POK. PMK is hyper visor kernel which response for scheduling.

Hi, all:
    I am the student who implement the GSOC2011 project hypervisor for RTEMS.
In my original proposal i wanted port the linux to the RTEMS paravirtualization hypervisor
named AIR. But as the progress of project, the plan had changed into adapt the
lastest RTEMS to the AIR hypervisor. So what i did is make the lastest RTEMS run
under AIR successfully which contains a paravirtualization RTEMS kernel named
POK. If you want to know any information please free to contact me


:) We are very interested. I didn't realize that AIR used Pok. Since I couldn't
get access to AIR, I was refocusing on Pok.  Julien Delange is responsible for
Pok. 

We would like to see RTEMS as a proper client under Pok and eventually
support the ARINC-653 API that way.  So getting your BSP into proper shape
on the RTEMS head and making sure others can run it is a BIG deal.
From there, we can begin to support other architectures supported by Pok
and provide application level ARINC services.
