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

« on: August 12, 2022, 11:22:31 am »

Greetings to the whole Power community, I thought that in order not to always create new discussions about each Kernel that comes out, make a single discussion that can contain all the main news and problems of the new Kernels on Power. I start immediately with the first test on the new 5.19.1 Kernel just installed and which seems to work without any kind of problem.

Dear friends of the Power community, I take up this treed to address especially the new arrivals. When you sign up for the forum, try to put some more information such as your country of origin. This can help you integrate better into the community and find any users from the same country with whom to exchange information and much more which I think is not bad indeed it can be an advantage ...! So please do not be shy, we are here on purpose to always improve the integration and development of the Power world!

GPU Compute / Accelerators / Re: Which GPU would *you* choose?

« on: August 10, 2022, 02:48:25 pm »

Unfortunately Nvdia, using proprietary drivers, does not get along very well with our Power9 machines and therefore consequently the resulting operation is never very good. For example, the old 2070 works but has limitations such as 3D acceleration which does not work. The only cards that are good and can be fully exploited are AMD at the moment ...

Well classic, your contribution is always precious, thank you very much, we await news from you then ... if you need something you obviously ask as always ...

Operating Systems and Porting / Re: Fedora 36: Kernel upgrade problem.

« on: July 12, 2022, 04:51:51 pm »

What I cannot understand is why on the petit boot it does not display the other 2, it is very strange in fact ... I never had such a situation when I was using Fedora ... You should also try in case with the question that shows all installed kernels and see what it says from that ...

 "rpm -qa | grep kernel"
With this you see more effectively if there are kernels installed, I would not like that through the command you give, it shows you some files but in reality there is not everything you need. Check well with that command and see if it gives you the list of 3 Kernels that are seen in the command you give ...

Hi, Petit boot on Fedora usually gets to see up to 3 Kernels installed by default. This is because I don't know if you know, Fedora by defoult keeps up to 3 installed kernels. So I don't know if you mean that you see the old one again and why you see it, or if you don't see 5.18.10 and you still see only 5.18.7 ... The post is not clear ...

Ok then a specific example that I can give you is the Street Fighter 3 game in its 3 incarnations and especially in its latest version which is called Street Fighter 3 third strike ... This is a game that goes very badly on our mame ...

I don't think they are specific drivers because usually MAME when it needs something specific requires it and makes you put it together with the roms. As I told you, they are a whole series of slightly more recent games, from a certain year onwards everyone does it. I've noticed this on all titles that are newer and from the late 90's onwards. I am sure that it is about optimizing the code because you understand that being a bit bigger games, it is already difficult to manage everything and if you start them with a much more modest hardware but based on X86, then the same games, with the same Roma, they go perfect. It's all about MAME on Power!
In my opinion the main problem is that this MAME on Power is simply a transposition from X86, not being written on Power, it does not exploit our processor at all and being a simple transposition, it has all the limits of the case unfortunately ...

NO Classic, I'm sure the problem is upstream, both the Debian version and the Ubuntu version have the same identical type of problem, Markr87 confirmed what I said and I'm sure the version of other distros will also have the same problem. The problem will be upstream, the one who deals with the Power version must review some parts in my opinion ...

Markr87 yes that's right, what I was telling you too, unfortunately several games a little less old than others, I can say, like, from the late 90s up, they have different functioning problems and that's why in my previous post, I highlighted this thing or that currently our mame does not have optimizations for our processor and therefore it goes badly on slightly more recent games and especially from the late 90s onwards ... Even today the last mame does not have optimizations that improve the situation and if someone does not specifically take our Power version and works on it seriously, we will never have improvements unfortunately ... The code must be optimized for Power ... But nobody knows how to update it and what repository is needed to do it?

Hi markr87, sorry but how does Tekken turn to you? I tried the old 2 and it already runs very slow and therefore lacks optimization, just as I said in the previous posts, how does it turn to you? I oh noticed the poor performance on both Tekken 2 and 3 and both Street Fighter 3 ... They all run very poorly compared to the X86 counterpart ...

I hope so much then, it would be a good thing.  But instead sorry, how should you do to keep it updated?  I have version 0.220 that comes with Debian 11 and I have noticed that if you do not advance in the operating system version first, MAME never updates ... Are there any specific repositories to install?  Thanks always.

Well TLE, so now finally Fedora can finally use MAME too, good news I would say. As you know by now I have switched to Debian, so I don't care much about what happens on Fedora anymore, but I am equally pleased that more software is coming. Unfortunately the main problem of MAME on Power is the poor general optimization, I noticed that several games that on the X86 version are very good, I am talking about old stuff above all, I am not talking about recent things for heaven's sake, but old stuff that unfortunately runs slow on Power and unplayable. Really a shame, it would be nice to know how to optimize the code and make better use of the available hardware, it would be really very nice!

Operating Systems and Porting / Re: New Kernel 5.16 and new problem

« on: May 28, 2022, 04:46:17 am »

Hello everyone, I tested the new Kernel 5.18 just released, I can tell you that you can finally compile and install the new kernel on Power without having to make any changes. They also fixed the last problem for which friend matgraf had to create the patch. Now you can compile and install your own custom Kernel without having to change anything. Tested on Ubuntu, in the next few days I will install it in a definitive stable version also on Debian.

« on: May 27, 2022, 03:08:01 pm »

But I didn't understand where you got the RPM files to tell the truth. Apart from that, I have no idea where to find those libraries of course, here the most knowledgeable about Fedora are Classic Has and TLE, except that Classic works on Firefox and so I think you don't use Chromium, TLE used and uses Chromium but I don't have idea if you currently have the latest version installed. I tried to ask but no one answered unfortunately. Maybe MPC7500 knows something because he also used Fedora a lot ... I've been using Debian for some time now, so no more problems thankfully but honestly I've always wondered how to make Chromium work new on Fedora .. .
