For anyone wanting a more affordable development platform for POWER9,
check out the Talos II Lite:
https://raptorcs.com/TALOSIILITE/
Hopefully we're getting down to a price point where coreboot development
becomes more practical (if still a bit painful)?
Looking forward to seeing coreboot on ppc64el systems!

Sorry, can't add today....it's a little over 6,000 pages of new
documentation.  Still, hardly light reading!

Register documentation was published today.  Links to the three volumes

That leaves only the PHB documentation in process at this point.  Almost
there....

I think I was being a bit pessimistic / too careful here.  We're

close
...
...
...
...
to getting the docs publicly released, but that doesn't help

anyone
...
...
...
...
wanting access right now, which is why I mentioned the other

route.
...
...
...

IBM's committed to getting the documentation released, they're

just
...
...
...
...
making sure that what they release is actually correct for the

products
...
...
...
...
it covers.

...
...
...
It might make sense to get our "working group" together over the

next
...
...
...
...
few weeks, by which time the documentation should be available in

public
...
...
...
...
form.

...
...
...
Are you interested in joining? :-)

...
...
...
of course, but not until those docs are freed up.
...
...
We're getting there.  First manual to be released is the processor user
guide.  More to follow, including register documentation, in around a
week.
...
...
...
Users guide:

Context: I've been trying for 2 years now to get OPAL released under
dual gpl2 licensing with the current apache2 license, apache2 and gpl2
are not compatible, so we'd be in a bit of a mess should we use OPAL
code in coreboot, and it would be easiest if we were able to use some
of
...
...
...
...
that code.
...
...
...
The first response from IBM was "why do you think you need coreboot?"
I
...
...
...
...
worked through that, and there was agreement in the end it ought to
happen, said agreement reached about 2 years ago. Stuff Would Happen,
I
...
...
...
...
was told. After that, silence.
...
...
We've reignited this.  It's underway. :-)
...
...
...
This is pretty much par for the course with Power. In 1990 I spent two
years getting an agreement that would allow me to .... get more
agreements.
...
...
...
We've plowed through this already and are at the action point.  For the
most part, just let me know what you need and I'll see if we can get it
published.
...
...
...
So close doesn't count. Once I see the kind of docs I need to see, not
requiring a clickwrap, and covering all aspects of every chip on your
board, I'm in: I'll order a board. Until then, I can't really do much.
...
...
Is the NIC an issue?  There are several people working on REing the
hardware with some great progress [1][2], but there's really no way to
get Broadcom to ever release official documentation.  Everything else
on
...
...
...
the libre-friendly non-SAS version either has docs available or we are
close to getting them published.
...
...
...
Thanks for your efforts on Power!
...
...
No problem!  We still consider Power the best path forward for powerful
libre systems at this point, getting really tired of the other vendors
actively working against efforts to create open firmware (this includes
SiFive at this point).
...
...
Will keep you posted as we get more docs published online, but thought
you and the others here might at least be interested in the users
guide.
