Operating Systems and Porting / Re: Ubuntu anomalies on Power
« on: April 27, 2021, 04:36:52 pm »
There are no critical issues on Ubuntu. Last time I tried Ubuntu 19.04 or 19.10. And Debian didn't use a outdated Kernel.

Operating Systems and Porting / Re: Ubuntu anomalies on Power
« on: April 27, 2021, 07:44:36 am »Hey Maury, I use my Blackbird as a desktop. I mean, browser (chromium and firefox), email client (thunderbird) and open office. I use it with Fedora and KDE Plasma. What difference would it make for a user like myself if the OS is Ubuntu, Debian or Fedora?
Here is a brief overview of the differences between distributions.
Distributions have different philosophies. This is also the reason why e.g. Debian uses older kernel versions.
One point that is not mentioned in the article are the repositories. The packages that are available on a distribution. At least from my point of view a big difference on ppc64le.
But all in all every distribution (Debian, Ubuntu, Fedora, CentOS, OpenSUSE, Devuan, Gentoo, Void) works very well on POWER.

Even on VoidLinux the package is listed as unavailable. So I guess, it's a bigger issue.

Blackbird / Re: Price of Blackbird went up $1,144 from April 2020

Order fees. Included since end of 2019, IIRC.

This has to do with a number of things. But it should be noted that the fees that were listed separately in the past are now included in the price.

This is my dmesg output. I can boot with this Kernel, but still get error messages. It seems my Navi card differs from others. Best Kernel with no issues is still 5.4.xx.

I've read somewhere that DG2 is Intel only or something like that. But can't find anymore.

« on: March 08, 2021, 10:34:05 am »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.

Operating Systems and Porting / Re: kernel config: page size 4k vs 64k

Both CPUs are 4-core.
At the end it's all about optimisations.
Improving performance of Phoronix benchmarks on POWER9
Easier Power ISA vectorizing for fun and profit with GCC x86 intrinsics

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:
https://openbenchmarking.org/result/2102047-HA-2101296AS71
Only difference: Kernel pagesize and installed RAM and of course the harddisk.
