GPU Compute / Accelerators / Re: AMD Radeon RX 6800 / 6900 (Big Navi) sales strategy

Has anybody else noticed this trend or been able to get the GPU standalone for a POWER9 system?

The availability in Germany is limited and of course overpriced.

Did you set the date to a correct value? Otherwise Ethernet will not work.

Both CPUs are 4-core.
At the end it's all about optimisations.

The graph is wrong
But the Phoronix test suite can't do anything about that. You have to divide the lower result by 4 (228)

These results you could compare:

Only difference: Kernel pagesize and installed RAM and of course the harddisk.

User Zone / BMC MAC address changes every time after poweron

Hello,

I thought the MAC address is unique? But it changes every time after poweron.
How can this be prevented?

Hello everyone,

I'm connected to the internet, but the clock dosen't sync.

Thanks in advance

You can't compare Debian and Fedora. Fedora is close to upstream (which means up to date packages) and Debian is focused on stability (which means they don't use the latest packages).

Applications and Porting / Re: Wayland support/port for PPC64el

« on: January 04, 2021, 07:17:55 am »

This is no surprise, since all distributions use, more or less, the same kernel.
And Kernel 5.4 needs the Navi patches.

As MauryG5 wrote, if I login KDE Wayland I get a black screen and have to restart the machine the hard way (push button).

It seems Wayland is not supported with Fedora 33 / Kernel kernel-5.9.16-200.fc33. I do not have a graphical card (use the standard HDMI that comes out of the OpenBMC), so no driver issue I suppose.

Running Wayland on the Blackbird was yet again an unmitigated disaster and I have not seen any information to suggest this has changed for simple framebuffers in general (so if you're a straight BMC-only system as mine is, fuggedaboutit). On the T2, Wayland is still not as snappy as Xorg, but performance was not massively different and window theming and decorations seem more consistent.

You could choose Wayland on the login screen. If you have auto-login, logout, choose Wayland, login.

I found this about KDE and Plasma on Fedora:

… Currently KDE still uses X11 and although there is a plasma-wayland session available, it is not considered stable or bugfree at this time ...

But will be default on Fedora 34

The Nvidia PPC64le driver allows you to use the GPU for compute (headless), only. Sadly.

As of today, sadly no news.
I think, I would pick a Talos-II lite if I want to buy a POWER9 mainboard.
