Can you please send the output of this command and your contact details in an email?

Code: [Select]
$ cat /proc/cpuinfo  | tail -12

It shows some more CPU and motherboard details

Please send me an email with your contact details, you can find my contact details here

Operating Systems and Porting / Re: [NEWS] Debian 11 is out
« on: September 10, 2021, 04:50:11 pm »

When I bought my Talos II, I did a fresh install of buster

As mentioned elsewhere, I rebuilt my kernel for a 4k page size and created Btrfs filesystems with 4k

I recently made a dist-upgrade to bullseye, Debian 11.  As part of the upgrade, I rebooted into the 4k kernel from buster so I could continue accessing my Btrfs filesystem

Then I built a 4k version of the 5.10 kernel package from bullseye.  Rebooting into that and the system runs fine.  I pushed my kernel here:

https://gitlab.com/dpocock/linux-kernel-debian/-/tree/pocock/bullseye-ppc64el-4k

After a week or so I had a crash, I'm not sure if that is the bullseye kernel or if it is just what I was doing at that moment in time.  I've been doing some development with GStreamer and VAAPI for the AMD Radeon cards and that has also produced some crashes so I'm not sure if this is because of bullseye or the testing that I'm doing with the GPU.

GNOME appears to be slightly faster when switching workspaces compared to buster.

Did you change the settings to disable Wayland and use regular Xorg?

That is what I'm using (Debian 10) and it is working well

That's a handy little comparison chart.

Thanks for this feedback

The integrated audio on the Blackbird is weak on lows and bass, and the mic input needs to be turned all the way up seemingly.

I'm using the Soundblaster X-Fi USB device

Output:   Talos II -> USB cable -> X-Fi -> S/PDIF (fibre optic, digital) -> Harmon Kardon AV system -> B&W DM604

Input: Rode lapel mic -> TRRS / 3.5mm converter -> 1/4" converter -> X-FI -> USB -> Talos II

It is working really well

For digital output to S/PDIF you don't need expensive hardware, any USB-to-S/PDIF device is satisfactory

Output is easy, but for microphone input, every component is significant.

Does anybody know about support for Firefox WebAssembly (WASM) on ppc64le?

Some web sites like Zoom don't work without it.

Since March, it looks like Jitsi Meet may require WebAssembly too

Is WASM available in any recent version of Firefox?  Can it be enabled if I rebuild Firefox from source?

The download here is working for me, this is a newer version in beta:

https://download.eclipse.org/eclipse/downloads/drops4/S-4.20M1-202104071800/

I'm using it with the autotools and C++ plugins.

7
Even on VoidLinux the package is listed as unavailable. So I guess, it's a bigger issue.

You can still download it directly from the Eclipse site using the link I provided above.

It does not work for me too.

Which Linux and Java version?

I took the download of Eclipse for ppc64el and tried it on my system.

It crashes at startup, I opened a bug report with full details, download link, stack trace
https://bugs.eclipse.org/bugs/show_bug.cgi?id=572837

Does it work for anybody else?

To test it:

Code: [Select]
mkdir ~/eclipse-test
cd ~/eclipse-test
wget 'https://download.eclipse.org/eclipse/downloads/drops4/R-4.19-202103031800/download.php?dropFile=eclipse-SDK-4.19-linux-gtk-ppc64le.tar.gz'
tar xzf eclipse-SDK-4.19-linux-gtk-ppc64le.tar.gz
eclipse/eclipse

General Discussion / Re: AMD RX 6900 XT from Sapphire NITRO [WIP]

Are you using Xorg or Wayland?

It is a good idea to try with both

Have you contacted the amdgpu developers to make a bug report?

As you are using the latest Fedora I suspect you have the latest dependencies, nonetheless, can you confirm you checked the version of:


amd firmware (maybe take directly from Git and copy into your system /lib directory)
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

mesa

Xorg or Wayland?  Try both


Maybe we need to develop a small reporting script that people can use to build a comprehensive report of each GPU test, all dependency versions, checksums, logs, key config values, kernel config, etc

It looks like retailers are building combined Ryzen + RX 6800 XT systems with OEM parts and you have to buy the whole system instead of buying the GPU alone.

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

When the new Blackbird is available I'll be happy to update my blog about it

I suspect each user has different priorities:

- for some users the GPU width is the biggest issue

- for other users the CPU core limit is the biggest issue

I suspect fewer people will be worried about the 2 memory channel issue but as part of the overall picture, it swayed me towards the bigger boards.

13
There is at least one support request open with Zoom about this.

Can anybody else confirm either you have the problem too, or it works fine on your system?

Please also share the Firefox build (e.g. Debian, Fedora, version number, ...)

I think it is good to have both options too, I'm not anti-64k by any means

On the other hand, the reality is that most developers in the Linux world, developers of device drivers and GPU manufacturers are only testing their products on systems with a 4k page size.  If the developers at AMD and NVIDIA include some ppc64le hardware in their test routines before a release then they are unlikely to release code that completely fails, as is the case right now.

15
In some cases, I think the build script (e.g. a configure script or Makefile) might call a function like "getconf(PAGESIZE)" and it saves the result

This is not good behavior but I think there are some packages like this but not very many
