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 ...

« 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

Applications and Porting / Red Dead Redemption 2 For Linux
« on: June 21, 2020, 03:28:08 am »
Hi guys from Power comunity, I just read that apparently, Rockstar Games, is working not only on a Windows version of this crazy game, but also on a Linux version and that even the Linux version is even more performing than its Windows counterpart. Now I wonder, in your opinion, will the sources be made available to develop it for Power as well? For us it would be a great blow because that game is impressive technically and already on Playstation 4. despite the limitations of a hardware of 7 years ago now on balance, has shown really good things. Today with the graphics cards we have at our disposal, I think it could be really great and we would make a quantum leap as a really great game software... What do the experienced programmers among you who already compile games with the sources say about it? Enlighten us... :-)

Operating Systems and Porting / Screen Saver disappeared
« on: April 19, 2020, 04:53:18 am »
Friends of Power good morning, it will seem trivial I know but since I use the dedicated graphics card, it seems that the screen saver has disappeared and I could not find it anymore. I'm sending you the picture of the error that I get every time I open the Screen Saver application, let's see if we need to change something to recover the screen savers that are present by default on Linux...
Thanks

General Discussion / RME HDSPe AIO
« on: April 11, 2020, 11:09:26 am »
Friends of the Power community, hello to all and happy Easter 2020 to all, even if in this good period unfortunately there is really little but patience, strength and courage.

As you can see from the title of the new discussion, I'm here to tell you about my new and last purchase for my nice Power system.
As you know, the very good Sound Blaster AE-9 that I got at the beginning, when I assembled what has become my Power computer, is not currently supported and so I can't use it. The fact is that I also wanted the dedicated sound card because I'm a fan of music, sound of my own and I love high quality and audio in particular, also I'm one who buys music whenever possible, in high definition formats that is Bluray audio and Super Audio CD, as well as some audio DVD if you can still find it.
So after some research I got interested in the RME AHSPe AIO which was the only one of the sound cards supported by Linux, to be in my opinion up to what I wanted and not to regret the AE-9. At first I wasn't sure if it worked completely and wiki didn't give me all the information I needed and so I probed the ground until I managed to find a forum where a guy had bought and tested this sound card for a long time. So I signed up and got everything explained and finally ordered it and luckily it arrived on time. I'll put a picture of the card just so you can get a general idea of what it looks like. So compared to the AE-9, which currently represents I think the reference point for quality sound cards on computers, this one has no separate power supply. So it's powered from the motherboard and probably in an absolute sense it's better to have separate power supply for minor disturbances, caused by other components like the graphics card and that can be detected. Another thing that jumps out at you is that the RME has two connectors to which dedicated cable assemblies are connected for the various input and output connections. This allows the RME to have more inputs and outputs than the AE-9, including the balanced ones that are not available to everyone and that the AE-9 does not have, but on the other hand these adapters are a bit cumbersome and can have some more dispersion than the direct ones connected to the card. An added value of the RME compared to the AE-9 in my opinion is for sure the made in Germany, from my friend MPC yes, this card is made in Europe and now I have the pleasure to say that my Power computer is mostly made in the West which today, especially in the world of consumer electronics is almost impossible! Reading a review of this RME, as a merit, they also wrote the made in Germany, so we agree that it's really an added value of this sound card and that RME is a beautiful reality just like Raptor, not a giant that eats only profits but a small company of people who do their job for passion first and this is fantastic. The components it is made of, you can immediately see that it is of high quality, there are 2 BB DACs, 1 Analog Device DAC, excellent analog section, in short you can see the quality of the board in the round. Of course the AE-9 boasts some of the most 'emblazoned components such as the ESS Sabre 9038 DAC, which is able to go up to a sampling rate of 384 KHZ with 32-bit digital signal processing while the RME comes to a very good 24-bit/192 KHZ. On the AE-9 you can change the operational amplifiers, making the board even more performing, but in general we can say that for Linux and Power so, in my opinion, better than the RME is difficult to find at the moment. Speaking about listening impressions so far, 
I can say that the difference with the integrated audio of the Blackbird is obviously heard, although I must say that the integrated audio of our beautiful motherboard always behaves well, but certainly for obvious reasons the dedicated card, especially if it is of quality as it is, it makes its superiority felt and it is also fair seeing how much it costs. The audio becomes more present, rich in detail, more dynamic and full-bodied, moreover, various possibilities open up in the professional audio field, with a whole series of operations that cannot be done with the integrated audio. Another differnza then that there is with Creative is precisely the approach that RME has with this sound card and with its products of this type, in fact this AIO, as well as the sound card previous to her, gives the possibility to expand the outputs and entrances in a very professional and qualitative way. In fact, there is the possibility of connecting 2 further boards with 4 other inputs and 4 outputs, dedicated, independent and with their own analog and DAC section. If on the one hand the costs are obviously higher, on the other you understand very well the type of product, a product born for professional studios and for making and listening to high quality audio, therefore a decidedly more professional and dedicated approach to a more professional market than Creative. The AIO card has a fairly important cost, its cost is 579 Euros (I speak in Euros of course but you can do the quick conversion into dollars) and if you want an I / O expansion card it takes another 200 Euros. I think next month I will buy the expansion with 4 additional outputs, so that I can connect some other pair of speakers and make a more enveloping audio. As regards the installation and configuration, just mounted, the card is immediately recognized by Linux, unlike obviously the AE-9 which has no support and therefore is not even detected and when it does it cannot be started due to lack of drivers. We therefore have immediate recognition because I have read that for some time now there are ALSA drivers installed by default in the Kernel and therefore these cards are fully supported. Having said that, however, to make it work, you need to install the ALSA-TOOS-GUI package which is now at version 1.2.2.1 and which is found without problems on the net. Once that is installed, a series of executables appear with mixer as an icon and when you open ALSAMIXER from the terminal, it allows you to act on the various channels, which before installing this package does not make you do. Except that really only HDSEMixer is working, which opens regularly and allows you to make various adjustments in detail. The remaining executables don't work I don't know why and the executable that has the hammer as its icon, what is called HDSPconf, does not open, I don't know why maybe there are some bugs that have not been resolved yet and therefore it doesn't work . In any case, this does not affect the functionality of the card at all, which is fine and can be managed both by the ALSAMixer and by HDSPeMixer. I'll post the photo of what this mixer looks like. Ultimately I can say I am very satisfied with my Power System, I lacked the completion of the ideal system and now with this card there is and I am very happy with it. I know that today only some of us are dedicated to audio on the computer because integrated audio is now working well and for many it is going so well that the sound card market has contracted a lot in recent years. I also know that in this Power community, maybe I'm the only one who has purchased the dedicated sound card and who loves this section, but I know that it can be useful to everyone in general to have further information on this section and in fact Raptor he asked to report all the impressions and all the information I had once I installed and tested the card.
