The POWER and PowerPC General Discussion / News Thread

The TenFourFox developer started a separate Talos-related blog at:

Sounds like something readers of this thread might be interested in.


Also, I found this on the LTT forums; apparently Dylanc1500 managed to get Portal 2 running on Power9:

I got Portal 2 to work on “my totally personal not work owned” POWER9 workstation with through Linux. It was a very rough experiment with some different drivers.

What the fuck I NEED A TALOS ALREADY

I wish I could afford a Talos and if I could, I would wait for the Talos III and have it use Power 10. I’s call my machine “To The Tenth Power” and named after one of the best tokusatsu teamups.

They are hinting towards a micro-ATX style board with one CPU:

[The OpenPOWER Summit in Amsterdam] would be our first reveal of the hardware for our next product…not ready to purchase quite yet, but you can get hands on time with the hardware and see if it meets your needs. We’re still being quiet about exactly what it is, but think http://images.overclock.co.uk/product_images … (1 CPU)

Talospace did a quick photoshop of the linked picture:


My hope for POWER10 is, that if they start using Multi-Chip Modules again (maybe using the misaligned ButterDonut mentioned by AdoredTV) it could be dramatically cheaper/likely for IBM to start making desktop or laptop size CPU modules.

There is this project:

but their current plans are to use NXP’s Power Architecture chips, which are not part of the OpenPOWER project; so I’m not sure how opensource or not the firmware situation will be.

That notebook is awesome. I talk with the guy on facebook sometimes.

Talking with the guy on LTT to learn how he made portal run. What OS, what software, etc. Kinda wondering if I’ll be able to run a linux VM in a POWER 9 or 10 box and have steam :3

@FaunCB Any interesting news from your discussions with Dylanc1500?


Something I found in a different thread, the next IBM POWER chips will be made by Samsung:

IBM itself confirmed to me that it was looking at foundries other than GF for Power10, and the only three options are Intel (well, its 10 nanometer) and we all had a laugh about that, or TSMC or Samsung. It will be Samsung. Power9 and Power9′ will be on 14 nanometer or 12 nanometer.

this is a comment from the author of a The Next Platform article


I also found this on the RCS wiki page for fixes in progress by the community; Marcus Comstedt on the amd-gfx mailing list is working on getting driver for RX 550 working under POWER9 in Big Endian mode.

Found this thread on an old HackerNews thread:

[Power] ISA 3.0 adds a new instruction darn – Deliver a Random Number. That’s a pretty good asm mnemonic :slight_smile: I wonder if anyone has dug into the details of how that works yet?

Wow that’s pretty good. My other favorite mnemonic is also from PowerPC eieio - enforce in-order execution of I/O.

The thing I love about the eieio instruction is that it serves the same purpose on-chip as in the song. Sort of a sync point.

And if you use it once, you tend to use it multiple times, each with a little code.

  • Peek a value that’s MMIO
  • EIEIO
  • Poke right back into MMIO
  • EIEIO

(yes, I am abusing blockquotes to represent this, sorry)

Woah WHAT

I need to start savitg for that talos my doods

i want one but im poor, all i have is this G5 with no GPU.
You have a bunch of G5s don’t you? Do you know what GPU I can get for it that will guaranteed do HWacceleration?

What G5 do you have? They have hardware limits because apple.

If it has pcie a 6600 would be great. If agp an ati 9800 would go ok. Needs to be the mac version though

AGP, i did order something on ebay at one point but the card was dead. It has a card that works, but theres no acceleration and it complains about a missing firmware package. Once I install radeon-firmware it fails to boot.

On linux or olx?

Linux
I don’t know what an olx is or does

Some more tidbits about the sub-Lite Talos II machine.

AKA normal market mATX boards that Tyan didn’t want to make unless money.

What Tyan mATX mainboard are you talking about?

The Talos II design is heavily based on the Romulus reference mainboard, which is the only other POWER9 Sforza board I know of. So this sounds like either a new design, or a minor redesign of Talos II’s mainboard.

I can’t find a mention of any Tyan POWER9 boards at all, although their POWER8 Palmetto system looks like it might be mATX.

Sources

This document describes Tyan’s POWER8 mainboards, Palmetto and Habanero:

In this thread on Twitter I asked about the difference between Romulus and Talos II:

(me)
How different is Romulus from #TalosII? Also, where did you get it, i.e. is it an IBM prototype or something like that?

@shenki
Different fan control, a few other minor things. It’s a reference design that the Tallos II is based on, so very similar

@raptorcompsys
Also no FlexVer support, proprietary CPLD toolchain, and all the normal bugs one would expect in a prototype. :wink: Still a nice machine for development though!

There was discussion of an mATX format board back in the Power8 design days lol.
