Applications and Porting / Google's Depot Tools (and eventually Chrome and anything else)

« on: February 16, 2022, 07:36:01 am »

I'm looking at building Dawn (with the idea to try some of the 3D tools from work on Power) and I'm stumbling at even getting Depot Tools to work. Starting with:

    https://wiki.raptorcs.com/wiki/Porting/Chromium_(New)

Building gn is fine, but then bootstrapping gclient fails (failing to resolve prebuilt packages for ppc64le). Since folks are building Chromium, V8, etc., is this just me not able to get started?

GPU Compute / Accelerators / AMD GPU at boot

« on: January 31, 2022, 10:05:58 am »

Before typing I'm already feeling the burning shame of a n00b question, but anyway, here goes...

I finally built my Talos II (dual 18-core), temporarily installed a Radeon RX 580 (I plan on a Radeon Pro W5700 but it currently has a waterblock fitted) and installed Ubuntu 21.10 (server install followed by desktop packages). It's early days and it's mostly working (Firefox 96 has issues, but one thing at a time). So far so good. I've disabled the built-in VGA via the jumper but it still starts up with this and then hands over to the Radeon card. Is this normal?

See the attached image.

Talos II / Film on Power9 CPU?

« on: January 27, 2022, 06:28:39 am »

I took some photos whilst building up my system and it's only on looking at the photos I noticed what appears to be a film on the CPUs?

I could take the heatsink back off and take a look a guess but wasn't sure the indium pad would still be good after doing so (or can I remove/refit the cooler as often as I like?).

Is it a trick of the light, my imagination, or is there a film that needs removing?

Mod Zone / 2U or 3U Heatsink Assembly Wanted

« on: December 21, 2021, 12:08:00 pm »

I'm looking to buy a 2U or 3U heatsink assembly to sacrifice for building a waterblock, does anyone have one for sale? I'm central Europe so would prefer to buy something already over this side of the Atlantic (not for jingoistic reasons, just that it's less hassle for import duty and taxes).

I already have a couple of 3U HSFs arriving with my system (any day now!) but I'd like something to dismantle and measure.

GPU Compute / Accelerators / GPU options as of December 2021

« on: December 12, 2021, 08:18:21 am »

What's the latest options I have for a GPU for my Talos II? I've a spare Radeon Pro W5700, which I'll try once my mobo and CPUs arrive from Raptor, but if I don't want to spend all my time tinkering, what are my current options? I can still pick up a WX7100 over here (Switzerland) but I'm loath to spend 700 on such an old card (then again, since I want to use my system and not spend all my time getting it running, is it still the best out-of-the-box choice).

I realise AMD is where it's at and the retired RTX 6000s I can grab from work will be of no use.

Applications and Porting / Clion, VSCode, IDE options?

« on: December 12, 2021, 08:10:37 am »

Hi! My first post... I'm waiting for my Talos II to arrive and have a question regarding IDE options. Having been spoiled with the choice of IDEs on x64 what will my options be on Power? Hopefully I'm not going to be stuck with gcc, gdb and a text editor? The answer to that shouldn't be clang and lldb...

Eclipse looks to prebuilt for IBM's Advance Toolchain, so I'm assuming I can get that running? Any other good choices?
