OpenBSD on UltraSPARC T1 - Done!

A few months ago I mentioned that Mark Kettenis was making quite a bit of progress in his efforts to port OpenBSD to the  SPARC Enterprise T1000 server.  Well last night this was posted:

Yesterday I committed the last bit of code to support machines with Sun's UltraSPARC T1 CPUs. Below is a dmesg for the SPARC Enterprise T1000, and although other machines have not been tested yet, machines like the SPARC Enterprise T2000 and Sun Blade T6300 are expected to work too. As you can see, we support SMP right from the start.

Whats this European code-slinger extraordinaire now working on?

LDOM support is not yet complete; I'm still working on drivers for virtual network interfaces and virtual disks. But domains with access to real hardware should work fine.

And after that we'll have to see what he can do with a T2 ;)

Congrats Mark!

Errata Mondatta - last two UltraSPARC errata docs public

Earlier today the last two UltraSPARC errata docs were published on the OpenDocs wiki:

UltraSPARC III aka Cheetah errata

UltraSPARC IIIi aka Jalapeno errata 

The original errata request we received from the OpenBSD community was for the UltraSPARC III chips.  Dorthe Clarke, however, the lucky person in the chip group tasked with driving this effort, felt that while they were at it, they might as well do UltraSPARC IIe, IIi, IV and IV+ (aka Hummingbird, Phantom, Jaguar and Panther). 

The publishing of these docs represents a considerable amount of effort that Dorthe and her tiger team spent, in addition to their day jobs, scrubbing, editing and reviewing the errata so that they could be made publicly accessible.  A big mahalo to all of you! 

Stay tuned as we continue to push our Open docs effort and search the dusty catacombs and dark recesses of old timers offices to respond to the requests we get for documentation.

NextGen UltraSPARC servers are here and Ubuntu's on board

Back in the beginning of August we announced our new T2 UltraSPARC chip and the fact that Ubuntu had already been booted on it.

Well today the systems built around these monster chips (they each have eight individual cores with 8 threads per core) made their debut and once again Ubuntu and Canonical are right there with us. 

The new systems are the Sun SPARC Enterprise T5120 (the 1U version) and the T5220 (the 2U version) rack servers [there is also the Sun Blade T6320 but that will have to wait until another blog :) ]  These guys have been designed to deliver humongous power and system utilization while at the same time delivering energy efficiency and savings (think of them as green monsters :).

These rack servers have already passed certification on the latest development release of Gutsy (Ubuntu 7.10) and will be certified on the final version to be released next Thursday.  Gutsy has a lot of goodies in it to help support the T2 chips so look for more info next week.

As Ubuntu proved over a year ago, SPARC isn't just for Solaris any more.

Ubuntu booted on UltraSPARC T2

I just got out of the UltraSPARC T2 launch about an hour ago.  Pretty impressive stuff.

The new T2 (code named Niagara 2) chip is not dual-core, or quad-core but eight individual cores on one piece of silicon.  Not only that but, unlike the chips from AMD and Intel, rather than having one thread per core, the T2 has 8 threads per core (in case you thought threads were only for sewing, think of a thread as an individual server that can run its own separate OS).  Do the math (8 x 8) and you end up with 64 threads.   Once again, pretty impressive stuff.

And of course, the Ubuntu community, being the overachievers that they are, have already booted Ubuntu on the new chip.  As Ubuntu and Canonical proved with the T1 over a year ago, UltraSPARC isnt just for Solaris any more.

I look after Sun's relationships with the various GNU/Linux communities as well as our relationship with the FSF. Last year, my family and I emigrated from Silicon Valley to Austin, TX.
