Operating Systems and Porting / Re: Trying out Chimera Linux

« on: November 01, 2022, 05:12:06 am »

I tested this distribution some time ago on my Talos II. From my perspective, the most discouraging part is Gnome.
I've been using this DE for more than a decade and with each release it gets worse and worse. Features that I care
about and that were good are disappearing. The stability of add-ons that bring back old functionality is unsatisfactory.
Before they work properly, the version of Gnome changes and the adjustment process starts from the beginning.
This takes more and more work and is frustrating. Add-ons such as DING Gtk4, for example, do not work properly
with an add-on such as Dash-to-Dock. GJS crashes every now and then, normal work becomes an ordeal.

I'm more comfortable with the concept as presented by ravynOS, I'm rooting for this project,
unfortunately at this moment there is no version for ppc64/ppc64le.

Operating Systems and Porting / Re: I am looking for a dnetc to count OGR-28 on PPC64LE

« on: October 24, 2022, 02:51:12 pm »

Some time ago I compiled a version downloaded from https://github.com/dcti/dnetc-client-base.git.
The PPC target compiles without problems but it's a 32 bit version and is nightmarishly slow.
For OGR28 it is about 10 times slower than the one for x86 on Intel i9-8950HK.

Operating Systems and Porting / Re: News, discussions and problems, about the new Kernels on Power

« on: October 14, 2022, 04:58:43 am »

If you can then test the operation of XFS. I mean such a case when root directory is on XFS partition and during normal system operation we will turn off the power by pulling the cable. Won't Petitboot hang on startup when reading this partition.  Version 5.12.17+ leaves the XFS partition in such a state that Petitboot is unable to read it properly, the kernel module crashes.

Talos II / Re: Petitboot lock after Fedora 36 update

« on: October 13, 2022, 10:00:15 am »

I've had two more XFS falls in the past two weeks. Once after another kernel update and the other after an unexpected power outage. This is definitely too much, fixing this situation is tedious and time-consuming, I have to remove the drive from Talos II and put it in another computer. Petitboot is unable to skip the stage of reading the state of the file systems on the SSD and inserting a rescue system on the USB does nothing.

With the current state of Petitboot software, it is impractical to install the main file system on XFS.

Talos II / Re: Temperatures and rotational speed of fans

« on: October 08, 2022, 05:23:40 am »

At the moment I have 5 140 mm NOCTUA NF-A14 PWM fans. Three do the blowing
from the front, and 2 do the exhaust behind and above the CPU. The 2 fans from the
front I have connected to one slot.

"Pcie temperature" may be related to SSD temperature:

Code: [Select]

# smartctl -a /dev/nvme0 | grep Temp

Talos II / Temperatures and rotational speed of fans

« on: September 28, 2022, 07:55:05 am »

I have a bit of a weird situation with the temperature and speed of the fans in my Talos II:

https://www.dropbox.com/s/iyzo0dllnmclwtx/Talos-II-Sensors-2022-09-28.png?dl=0

Should the control system not increase the speed to lower the temperature on this one sensor?

Problem solved. I took out the SSD drive, checked the XFS partitions on my laptop. Nothing wasn't happening, there weren't any mistakes. I put it in Talos and it works.

I am one step further in analyzing the problem. I looked at the /var/log/obmc-console.log log and found something like this:

Then it's something with an SDD drive and an XFS file system on that drive. I took out the SSD disk and Petitboot came back to life

BTW. Does it make sense to replace Petitboot 1.12 with 1.13?

This is what this upgrade step is called, I don't know exactly what the Fedora installer is upgrading then.

Talos II / Petitboot lock after Fedora 36 update

« on: September 26, 2022, 12:07:45 pm »

Today, after the Fedora 36 update, I had an unpleasant surprise. The first phase of the system update went as usual without any problems.
Then, as recommended, I restarted the machine and the firmware update phase began. After this process was completed, it was rebooted
again and here are the problems:

• Petitboot did not detect the disk, there is no list of possible kernels to load;
• USB keyboard stopped working, locked on all USB sockets
• the "Power" button stopped working, I couldn't turn off the machine
• At the bottom of the screen, Petitboot wrote the message "Info: Waiting for device discovery"

Any ideas?

Minor fix, after the next restart the "Power" key works.

I made a video of how the boot process works: Petiboot after F36 firmware update

General OpenPOWER Discussion / Re: Request for proposals: Who to donate my Blackbird and Power 9 CPU?

« on: August 19, 2022, 09:58:22 am »

I spoke to Kallisti5 some time ago about PPC, but he was not interested and basically dissuaded me. I am a Haiku user and was very keen on the system. You'll even find me on the authors list, I've thrown in a few minor tweaks to the system. I even tried to compile Haiku on a PPC but the task overwhelmed me, I can't devote that much time to it.

I think helloSystem is dead compared to ravynOS.

The Haiku community now has little interest in PPC architecture

Maybe ravynOS, it's an interesting project.

General Discussion / Re: HighPoint SSD7505 RAID tools for ppc?

« on: August 12, 2022, 12:36:22 pm »

I bought a HighPoint SSD 7502 adapter for my Talos II and I am unhappy with it. With only one CPU, it's a misunderstanding. I knew I was going to have RAID problems and was mainly concerned with accessing two SSDs. Unfortunately this adapter takes up a long PCI slot and I can't use it together  with a video card.

Talos II / Re: Indium pads required for 18-core CPU on Talos II Lite?

« on: July 29, 2022, 05:59:05 pm »

I bought my Talos II with Power 9/18c from Vikings and did not get an indium pad either. To the same question I got the answer that thermal paste was enough. I applied it and it works without any problems.
