[belenix-discuss] SPARC64 (T2+) port of Belenix?

[Cedric Blancher]

Are there any plans to support SPARC64 (i.e. Sun^WORACLE T2+) in Belenix?

At present we are only looking at what is coming from the Illumos project esp the kernel portion.
There is no specific plan and among us only I have experience on Sparc from my years @ SUN. We also do not have access to any T2+ boxes to test on.

I cannot speak for Illumos, but SchilliX-ON, the independent OpenSolaris-ONNV
continuation project is compiled on Sparc every time there is a change to
break something. So we know that the SchilliX-ON base compiles on Sparc.

In aprox. 2 weeks, SchilliX will most likely have a new (intel) version that is
based on a completely SVr4 package based CD creation procedure. From now, I
would guess that it makes sense to talk about a sparc variant in aprox. 2
months from now.

Joerg, please stop your SPAM for SchilliX. So far I know, no person is
using it. It's also VERY offtopic here.

Hi Irek, I'll send a mall tomorrow about what's off topic and what's not, as well as about acceptable behaviour, including my opinion of responses such as what you have given to Joerg.

Joerg, I'll be writing to you privately and shall respond to some older mail between us. Till then, I ask that you don't reply to mails on belenix-discuss or belenix-dev. There are various expectations to set all over the place for everyone.

Ram

Sorry to nitpick here but SPARC64 and T2+ (UltraSPARC T2+) are technically not the same thing, while they will both run Belenix if it were to be available for either of the platform.

SPARC64 architecture is a sun4u based architecture and T2+ is the sun4v architecture (both implement and extend SPARC V9 ISA nevertheless) and from a core design perspective, they are _VERY_ different.

Sorry but I spend too much time very day explaining SPARC to people... ;)

Cheers,

Abhishek

P.S: It will be cool to see if we could get belenix on SPARC, but I reckon that we will have very few people using it..

Thanks for the explanation. Yes sun4v and sun4u are different
architecturally.
I remember the additional testing we had to do in the Sustaining team when
sun4v was originally introduced and the extent of debates we had with respect
to the assumptions that were made in the original T-series processors. Some
of the assumptions were proved too conservative and had to be changed in
the later designs of the T-series procs. Very interesting stuff by itself.
But I guess the question was from a general Sparc support point of view. T2+
is more interesting to most people I think.

Moinak.
