Xen devel - Feb 2010 - Flashing SLOF on IBM JS20 (Thamesblue supercomputer)

Hi,

We are trying to set up XEN testbed on Thamesblue Supercomputer which has
IBM JS20 Blades. I compiled the SLOF firmware from the source on one of the
blade. The compilation went smooth and generated the following binaries

*boot_rom.bin
boot_rom_bimini.bin*

When we try to flash boot_rom.bin firmware binary then we get the following
error:

* update_flash: RTAS: validate() Invalid candidate image for this platform*

whereas if we try to flash the original IBM firmware then it install
smoothly as shown below:

*update_flash -f /etc/microcode/ibm_fw_bios_*
*fw08401160_anyos_ppc64.img
info: Temporary side will be updated with a newer or
identical image

Projected Flash Update Results:
Current T Image: 2b606_470
Current P Image: 2b405_131
New T Image:     2b608_401
New P Image:     2b405_131
Flash image ready...rebooting the system* ...


I used the following procedure to compile the slof-JX-1.4.0-0 on IBM JS20
blade

$ tar xzf slof-JX-1.4.0-0.tar.gz
$ tar xzf slof-JX-1.4.0-0-oco-gcc412.tar.gz
$ cd  slof-JX-1.4.0-0-oco-gcc412

$ chmod 777 install-oco.sh
$ $ ./install-oco.sh ../slof-JX-1.4.0-0

$ cd ../slof-JX-1.4.0-0
$ export CROSS="" # native compiler

c06b11:/home/ah/firmware/slof-JX-1.4.0-0 # make -s
******** Building js2x system ********
 ====== Building slof ===== ====== Building rtas ===== ====== Building clients

Please help.

Thanks.

Best Regards, Hassan

Hi Ahmad -


I could be wrong but I suspect the number of people on either xen-users or
xen-devel that are using Xen on IBM Power (or are even familiar with Xen  on IBM
Power) is a very small number, possibly even zero.  As far as I know, the XenPPC
port was never fully functional and development stopped in 2007.  Your best bet
might be to work through your IBM hardware support contacts to see if anyone in
IBM is willing to help.  Or possibly there are other system-software-related IBM
Power mailing lists that could help more effectively.
