Operating Systems and Porting / Ubuntu 22.04 LTS
« on: April 24, 2022, 05:04:45 pm »
Guys I tried to update Ubuntu 21.10 with the new version 22.04 because now I've been keeping Ubuntu installed on a hardisk for some time and I like to try the news and see how it goes. What I can essentially say are 2 things, the first is that from the point of view of the general management of the operating system, Ubuntu confirms itself as the best there is currently on Power. The fluidity in moving the various pages and the whole Gnome 42 is truly fabulous, better than 21.10 which still had some uncertainty while still being overall good and well usable. So while fedora gets worse and worse and you are forced to manually install optimizations, Ubuntu is getting better and better and currently has the best handling of Gnome 4X that there is on Power. The second thing I noticed is that the more it evolves graphically and in general management, the more it regresses in terms of software in general. Let me explain better, his damned criticisms increase more and more! All this is incredible and it gets on a lot of nerves honestly because it's a shame to see a distro that is so good on a technical level and then gets totally lost in use. In the meantime, the first thing that catches the eye is that Firefox, which was already suffering from big perennial problems, of which I have spoken to you several times, as if by magic it totally disappears and you never see it again ... It has disappeared from me. pure Grub Customizer which I used to manage the 5.15.X Kernel booting. I tried to insert the Raptor repositories for Chromium and once I save, if I try to reopen the software & update to insert the key, the application doesn't open anymore and I have to remove the Raptor repositories ... I didn't go further because 'already' I was nervous enough and I gave up from continuing to try but probably if I continue I also find other criticisms that have always been present on this distro on Power and have never been resolved. So I wonder how it is possible that still no one tests this distro to try to fix all these criticisms that have always afflicted him, crazy, I'm speechless ...

User Zone / Clone hardisk Linux
« on: February 02, 2022, 06:38:15 am »
Power friends good morning, I have a question to ask you, I would like to clone the hard drive containing Debian 11 and bring it to SSD, currently being that I was just testing it, I have it on a mechanical hard drive.  What is the best procedure you recommend, without obviously doing damage?  Thanks always!

Operating Systems and Porting / New Kernel 5.16 and new problem
« on: January 15, 2022, 10:32:42 am »
Dear guys you Power, as you know the new Kernel 5.16 has just come out and I like to do it as usual, I wanted to try it immediately, compiling my version.  Obviously now from 5.14 onwards you have to set the AMD GPU parameter to 0 otherwise it won't start.  Well after having done everything and started this beautiful news appeared to me, which you can see in the picture and at that point everything freezes and eventually it does not work and you have to do a reset and restart ... I say it is possible never that every time there must be a new problem in these Kernels ??? !!!!  I can not understand!

Applications and Porting / Proton on Power
« on: November 27, 2021, 04:24:55 am »
Hello everyone, lately I have read some articles about the great development that the Proton application is having on Linux and I have also read that it is completely open source and therefore accessible. I searched first in the various sections of the forum but it seems to me that I have not yet found anything about it. Do you have any news if this Proton will also come to us on Power?

General CPU Discussion / The point about Power 10 currently
« on: November 25, 2021, 01:41:09 pm »
Friends of the Power community, I think the time has come to take stock of the Power 10 situation because in my opinion at the moment there is a bit too much impatience combined with general confusion. So currently, if you have read everything correctly, it is clear that Power 10 was launched by IBM but only and exclusively for the 1080 series servers and we all know that they are the high-end ones. Furthermore, it has been repeatedly observed that the processors currently in use by these servers, obviously are the high-end ones, ie with a minimum of 15 cores (16 but one is turned off if necessary) and a maximum of 30 cores. Now we all know well that these numbers, also linked to the range to which these servers belong, clearly makes us understand that these are CPUs clearly of the type to understand, direct successors of MONZA and LAGRANGE of Power 9 and therefore high-end. It is perfectly obvious that currently, even if the firmware were completely free, Raptor would not be able to produce a P10 based motherboard on the spot because the costs would obviously be prohibitive. So the reasons that today cannot lead to a production of P10-based motherboards are both the current lack of free firmware but also the lack of medium and low-range solutions, equivalent to our current Sforza P9. So I would say that instead of continuing to ask Raptor when and if it will produce P10 based cards, we should concentrate on waiting for the release of the mid and low range solutions in the meantime, which I don't think will arrive shortly and later, once they start. to exit, then also see if IBM will start as I think, to release the firmware sources completely open and ask Raptor what programs they will have at that point on P10. Currently I repeat, there is nothing feasible because even if the firmware were already free, the prices are prohibitive and there are no CPU offers equivalent to Sforza which is what we all use on our Power systems for desktop. and small home servers ... Let's be patient and see what will come out maybe already in 2022 by IBM on the medium and low range and then we will start to have everything clearer!

Operating Systems and Porting / New Ubuntu 21.10
« on: October 17, 2021, 04:02:09 am »
Guys, the new Ubuntu 21.10 is out and as I imagined, it has a much smoother and more normal Gnome 40 handling than Fedora. Canonical has in fact waited to use this version just to fix some of the problems it had and so now we at Power can also benefit from a normal and fluid interface almost as it should be. Also on the audio sector they preferred to stay on Pulse Audio and not switch to Pipewire given the problems encountered with the dedicated sound cards and which I myself have reported to the Fedora team. I upgraded yesterday morning and have been testing the system ever since, everything seems to be running fine and as it should so far.

Firmware / HostBoot VS CoreBoot
« on: August 30, 2021, 08:14:59 am »
Power Community Hello everyone, connecting to the HostBoot / CoreBoot speech just started thanks to our new member and friend Pietrushnic, I wanted to start analyzing more concretely what it is about. I'll post some links where you can clearly see the net difference in startup between the classic BMC startup in HostBoot mode and the same then, in the new CoreBoot mode. You can clearly see the marked difference of the two starts and I must say that the conditions for this new type of firmware in CoreBoot are really good. We know how slow BMC is currently booting into HostBoot mode, we have been talking about it for some time if I remember correctly, about how to speed up this boot a bit. Well, a possible solution is given by those of 3mdeb, with their new firmware written in CoreBoot that from what you see in the videos, from a nice acceleration to everything ...

https://github.com/3mdeb/openpower-coreboot-docs/blob/681ecad510d66a1f2e5cced06596c1cd10f3855b/devnotes/user_perspective.md

You can see that in the test, entering the Talos BMC with a second computer in this case, a test is performed with HostBoot boot which is the current one we use and then a boot in CoreBoot which is what 3mdeb is working on ... The improvement it seems remarkable to me ...

Good evening everyone and happy 4th of July to all the american friends of the Open Power community and to all the Raptor staff of course, I know it's a holiday in your country so I take the opportunity to wish you a happy 4th of July. I'm trying to compile the new Kernel 5.13 but I don't know why it gives me some compilation errors that I can't understand because they don't lead me to anything that could be missing. I've installed all the new libraries that you asked me but unfortunately I always get compile error, do you have any idea of what is changed in this Kernel, that sends these compile errors on Fedora? On Ubuntu for example I had no problem and currently I'm successfully using the new Kernel 5.13 without problems. I'll show you the errors it gives me....

Operating Systems and Porting / Ubuntu anomalies on Power
« on: April 26, 2021, 06:49:33 am »
Hello to the whole Oper Power community, for some time I have installed Ubuntu in one of my hard disks and immediately afterwards to use my RX 5700 XT Navi 10 card, I compiled a kernel specifically. Using Ubuntu and checking the various features with respect to Fedora and Debian, I realized that unfortunately this distribution has various criticalities. I had also noticed it when I just bought the Blackbird, I tried Ubuntu first and unfortunately I saw that these critical issues are still present and they are bothersome as well. Specifically, I refer to the Firefox bookmarks for example, only on Ubuntu this browser gives this perennial error, since I installed version 19.04 and now that we have reached 20.10, the problem persists. It says there is probably a problem with the security software that an Ubuntu does and therefore there is a conflict but how come they still haven't solved it after years? I also tried to do what the guide says, eliminating directories that he himself indicates but the problem persists. Another very strange thing is the connection to the network. The system is regularly connected to the network but the icon at the top right indicating the connection is partially cut off, for him it is as if there is no network, press the connect button but nothing happens, yet the system is regularly connected to the internet. Problem that has also existed for years and has never been solved by the Ubuntu team. Another anomaly resides in the numeric keypad, the numbers are inverted, instead of starting with the number 1 from the bottom left, it starts with the same from the top always to the left and therefore instead of the number 7. 7,8,9 become 1, 2,3 ... Another anomaly occurs when using the Gnome software center, Ubuntu does not have it by default like Debian or Fedora and so I downloaded it, when you try to install an application after selecting it, he puts waiting without ever starting to download ... Honestly it is a shame that it has all these critical issues because as an optimization it is perhaps the best on Power, it is more fluid even than Fedora at the moment ... a real shame, if anyone knows how to solve these critical issues would be a really good thing ...

Operating Systems and Porting / Fedora custom kernel does not install
« on: February 02, 2021, 03:25:23 pm »
Hi everyone, I mentioned a few days ago that I have problems installing the custom kernel on Fedora and at first glance it seems that you don't understand what happens. So I thought about creating a dedicated discussion because apparently I'm not the only one to have this problem and talking with our Evan Meklort who is one of the most prepared on the Power and Linux world in general, he pointed out that it has been opened a bug report in the RedHat channels where they describe the same problem I have as soon as the "make install" command is run! I don't understand what they mean but it seems that the problem is caused by a file called Dracut and which actually has in a line of its code, the very message that then comes out when I try to install the Kernel just done. Evan told me that he wanted to check for himself but he still hasn't given me an answer, do any of you know about this situation or understand better than me what is going on? I am sending you the link of the bug report to find out if you can better understand what it is ...

General CPU Discussion / CPU Power 9 8 core piĆ¹ veloci e prestanti
« on: November 24, 2020, 01:01:36 pm »
Greetings to the whole Power community, today I chatted with Raptor and asked them if it was possible to have a different CPU from those sold by them up to now. Specifically, it is the 02CY977 DD2.2 model or equivalent DD2.3 or 02WP000 which always have 8 cores but have a 3.8 GHZ base frequency and can be overclocked to 4.1 GHZ consuming 190 W. They replied that the minimum order is 30 pieces and I was wondering if there are people like me interested in this CPU so I can collect 30 orders and do a small upgrade with this model. Are we interested?In my opinion it would have been better to market this and not the current DD.2.3 which is the same as the previous one and also the performances are only slightly higher, while I think these have a slightly higher performance difference and consequently in my opinion they are more interesting. We have 2 models of 4 cores and 2 models of 8 cores that are almost the same, like almost doubles and instead with these models we would think something a little different and more performing ... Let us know if we are interested in this model and let's talk to Raptor in that case ...

Applications and Porting / Video Encoding
« on: November 08, 2020, 03:12:39 pm »
Hi everyone, for some time I have been testing high definition video on my Power system and I realized that I cannot go beyond the 1440P. From what I know, unfortunately on Power the video decoding is not optimized to the best and consequently, the performance is not what you can get on an X86 or ARM system. Whatever application you use or whatever browser you use, in the end you can't get regular and fluid 4K content unfortunately but only in 2K. My question at this point arises spontaneously, will we ever manage to have one day, the optimization we need to finally have a video decoding worthy of the name? It is not known ...

GPU Compute / Accelerators / Current support distributions for Navi AMD
« on: September 07, 2020, 04:05:17 am »
Hello everyone, I wanted to know if to date, as well Fedora, if there is some other distribution of Linux for our architecture, which has the drivers to normal operation GPUs AMD series  Navi 10/14. Someone has information about? Thanks

Applications and Porting / Raspberry Pie
« on: August 19, 2020, 04:17:55 am »
Hello everyone Open Power community, in these days I came across the RaspBerry Pie world by chance and I got some research on how it works. I saw that being based on Linux, the whole emulator system and the whole retro pie application, can be easily installed even on X86 based computers, (the original Raspberry version is on ARM). I wonder now, there is no version of Power for us today, right? As usual, it takes someone who takes the code and brings it to our system ... Do you have any more news?
Thank you

Firmware / CPU Firmware
« on: June 22, 2020, 03:34:18 pm »
Hello, all power community, I had a question for everyone in this fine community that I understand you're all pretty much all but me... As we all know, one of the advantages of Power is that it gives us the power to rewrite, for example, the CPU firmware to our liking. I wonder at this point, what skills are needed to do it and what real advantages does the power bring? I'll give you guys the word if you want...
Thank you
