SUN OBP source code released

[Jose Renau]

Hi all,

  SUN has released (under BSD license I believe), the source
code for their OpenBoot (OPB). This includes the forth programs
for many of their sun machines.

  This is available only starting from version 1.3 of OpenSPARC.

   http://opensparc-t1.sunsource.net/download_hw.html

  I guess that it could be a good boost on the functionality/code
available at OpenBios.

The mode of operation in this version is that OBP talks to a hypervisor, it 
does not access hardware directly. So for example the low level code could 
be used in making OpenBIOS run on top of the hypervisor, but would this be 
useful? Higher level code could be used elsewhere, but I'm no Forth expert.

The hypervisor sources are very Niagara-specific.

Actually I don't know what to do with this otherwise very nice package.

That sucks, I guess that Sun only released the OpenSPARC version. In 
that
version, the hardware implements the hypervisor (sun4v).

mitch bradley has already ported it to OLPC.

I think it's useful stuff. Mitch, did I miss anything?

What I ported to OLPC was the FirmWorks Open Firmware, which shares a 
lot of core code with OBP (all of which I wrote).

Sun and FirmWorks are planning to release a *lot* more stuff Real Soon 
Now.  Within weeks.  Stay tuned.

Did you need to add code to x86 kernel to use open firmware interface?
