<pre>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.

OK. Doesn't change the basic premise of my response.<br>
<br>
+ Your work needs to be in a state to merge.<br>
+ We need to reproduce your testing independently. <br>
+ Paravirtualized BSPs are good things.<br>
+ Pok support is desirable.<br>
+ ARINC-653 support is desirable.<br>
+ Is there a way to have a paravirtualized BSP which<br>
could run on different hypervisors?<br>
<br>
The last point is easy to gloss over but is desirable because<br>
then we would only have one BSP to support long term. Even<br>
if some code differed, structuring the BSP to make this happen<br>
would be of benefit.<br>

font-size: 14px; font-family: arial;">Hi, all:<br>
I am the student who implement the GSOC2011 project
hypervisor for RTEMS.<br>
In my original proposal i wanted port the linux to the
RTEMS paravirtualization hypervisor<br>
named AIR. But as the progress of project, the plan had
changed into adapt the <br>
lastest RTEMS to the AIR hypervisor. So what i did is make
the lastest RTEMS run <br>
under AIR successfully which contains a paravirtualization
RTEMS kernel named <br>
POK. If you want to know any information please free to
contact me<br>
<br>

:) We are very interested. I didn't realize that AIR used Pok.
Since I couldn't<br>
get access to AIR, I was refocusing on Pok. Julien Delange is
responsible for <br>
Pok. <br>
<br>
We would like to see RTEMS as a proper client under Pok and
eventually<br>
support the ARINC-653 API that way. So getting your BSP into
proper shape<br>
on the RTEMS head and making sure others can run it is a BIG
deal.<br>
From there, we can begin to support other architectures
supported by Pok<br>
and provide application level ARINC services.<br>
