Blackbird / Re: [amdgpu] [Fiji] Fedora 32 Linux kernel 5.7.x crashes
« on: September 23, 2020, 03:22:04 am »
I assume it has nothing to do with that, because with kernel 5.4 and the patch it worked perfectly. It's a FP regression (at least for Navi).

General CPU Discussion / IBM POWER9+ ?
« on: September 21, 2020, 10:43:47 am »
Because it will still take over a year for the POWER10 to materialize, I was wondering if IBM would participate in a POWER9+? A die-shrink of the current POWER9 to 7nm or 5nm.

Since the POWER9 is open-source, how difficult would it be for Raptor to do this or to order it from e.g. Samsung?
In the long run it would probably be advantageous in price and Raptor would be independent from IBM.

Raptor don't wait for orders. A new batch of Blackbird mainboards is on the way.

Debian (sid) is still available for big-endian systems.

OBS-Studio should be available on sid and Bullseye. Can't you just activate the repository for this package only?

I am actually considering getting another Blackbird just so that I can continue learning software compilation without having to worry about blowing away my primary system again.

You can install multiple distributions on one disk. Or just buy a second hard disk.

Edit: OBS is also available on VoidLinux PPC64le

I have decided to try the following distributions:

ALT Linux
Arch Linux
Devuan
KISS Linux
PowerEL

Then I tried almost all of them.

Yes, since Kernel 5.8.6 I get also a black screen.

The Navi problems are Kernel related. You will face that problem on any POWER-distribution.

I never tried myself, but memtester should work.

And for Navi you need at least Kernel 5.6.13 or these patches.

Operating Systems and Porting / Re: installers not booting
« on: September 04, 2020, 10:10:21 am »
In July I have read that the Bullseye installer is using serial port for some reason. I would try to sshing into the TalosII.
root@talos -t -p2200. The password is in the mainboard package. The paper looks like a sales slip.

Here is an overview of working HBAs.

That sounds like a good strategy.

But I'm afraid that the new Navi-GPUs will have the same problem as the old one.
With Navi-GPUs, fast-reset must be disabled. Which is quite annoying.

I still have kernel problems. The GPU does not crash, but that's probably where my sound problems come from. I dunno if it depends on the model, but I guess that it concerns all Navi-GPUs.

Regarding RX 580 I would buy either a Sapphire Pulse Radeon RX 580 8GB or a PowerColor Radeon RX 580 Red Dragon V2 8GB. But this is a question of taste. Performace/ noise-wise these are pretty good, IMO. Each costs approx. €170.

Too many drawbacks.

A Polaris GPU causes far fewer problems. The performance between RX 580 and RX 5500 is almost identical. Performance/price ratio between RX 580 and RX 5700 is also better.

I have a Navi, too with no problem and the R9 Nano is a Fiji-GPU, AFAIK.
