Dear all mentors and rtems users:
  I am very glad to report the progress of GSOC2011 hypervisor for RTEMS. In the past about one month my main work is to
merge the Hypervisor and partition OS which is based on rtems4.8.1 to the latest RTEMS version. Until now i have basically
realized the goal that the sample test case can run successfully on this platform despite of a small bug. By the way all above
work is based on LEON3 hardware platform.
  About the merge of Hypervisor the main work is to modify the LEON3 BSP code and very little score code related to sparc cpu.
Because the Hypervisor kernel code is independent to RTEMS code and is also build separately. So this part of merge is just a
patch for LEON3 BSP to RTEMS latest version.
  About the merge of Partition OS the main work is to development a new BSP for all sparc architecture and also very little
modified code to score code related to sparc cpu. And another work is to update the build environment of sample test including
Makefile and linkerfile
  And now the sample test can successfully schedule a cycle including four partitions OS and each partition with three or four
tasks. But when it schedule the second cycle it will only execute each partition OS‘ idle task. For example, the schedule table
arrange the schedule order as follow: P1->P2->->P3->P4->P1->P2->P3->P4->......... and each partition OS arrange its tasks
execution order is as follow :P1: P1A->P1B->P1C->P1idle     P2: P2A->P2B->P2idle   P3: P3A->P3B->P3C->P3idle  P4: P4A->
P4B->P4C->P4idle.   so the first overall schedule cycle order is as follow:
The above is successfully test on the platform of Hypervisor and Partiton OS all based on RTEMS4.11. But when the second
schedule cycle starts all the partiton OS is entering into idle tasks all the time. Tobias, any idea about this problem?
Any comments is welcome.

Best Regards
