Ditching the Linux kernel is probably a good idea. Or at least run your own fork. Which I expect that many state actors and large companies already do. Also, I suspect that we'll see more large public kernel forks sooner rather than later. Even sooner if Linus retires.

To be honest, I don't care that much for myself. Guess I wasn't completely honest in OP. I'm just a nobody who gladly exposes his soft parts in exchange for cheap and easy access cat videos and general dopamine. Rather I'm thinking about what strategies policy makers, companies, NGOs and the general public should consider, as we crash into even more exciting times.

 

I'm thinking that software like Signal, Bitwarden, Firefox and RHEL is more likely to be pushed (by unconventional methods) to introduce backdoors under Trump 2.0. Less complex software that is developed by an international community is of course less suseptible.

What do you think? Will the risk be higher during Trump 2.0 or is the FOSS community diverse and international enough? Am I just paranoid and irrational?

Closed source software and cloud is of course a no brainer since always. But clompex FOSS with centralized development and hosting pretty much suffers from the same problem.

Ah, I think I have a better understanding of the PCIe hardware protocol now. Feel a bit more confident regard a 2 x8 setup. Thanks.

Just for the record: my understanding is that the HW protocol performs a handshake which settles the number of lanes that will be used when establishing a link. And the PCIe standard is always backwards compatible, so things should work just fine even if I buy something that says PCIe 6.0 later. Or at least the lower layers of the protocol should be compatible. And as long bandwidth isn't an issue.

Your contribution was noise. Not an answer. Do better next time.

Maybe I should rephrase my question.

Are PCIe 5.0 or backwards compatible 6.0+ devices (GPUs), that say x16 (16 lanes) in their product specification, required by the PCIe standard to also support only 8 lanes? I.e. can the device transceiver decide to not connect if not all lanes are available at the protocol level? I'm not referring to slot size here.

The thing is that there are motherboards that have 2 PCIe 5.0 16x slots that are connected to the CPU (hopefully not false marketing). But the slots are downgraded to 8x if you connect two devices, since a AM5 CPUs only have 24 lanes.

I probably need to read the PCIe 5.0 standard document if I want to be sure.

I did Google and I didn't find an answer.

Also, you might grow a little bit as a human by reading this thread : https://lemmy.zip/post/27991591

This is related to my previous question about AM5. Turns out 2 8x lane GPUs on AM5 might be an option after all.

So my question: Does a 16x lane PCIe GPU always support x8 lanes as well? (Like a Radeon RX 7900 XTX or something bigger and better from the future.)

It could also be that this is not sanctioned by China and that the crew members are working for Russia. It's not obvious what China gains from this kind of behavior. China is very dependent on European good will and trade. Especially as the trade war with the US intensifies.

Isreal has created a situation where they rely on the far-right in the US for their survival. The same people that was openly anti-semitic about 15 years ago. And will be again, as soon as they forget about the current anti-muslim hype (which is waning). At the same time they have created a situation where maybe 50 million people are willing to die if it means removing Israel from the map, and maybe 6 billion people who thinks it's probably a good idea if Isreal is removed.

USA and the EU has to prepare for 10 million Jewish Israeli refugees, within this century. I believe.

The US Israel lobby is largely responsible for this situation. Responsible because they've pushed the US into a position where they reward Isreal for whatever crazy fundamentalist genocide agenda they run. And Israel is now so good at the operative and tactical level, that they've completely forgotten about the strategic and geopolitical level. For which they will pay sooner or later (tiresome comparing with Nazi Germany, but the situation is very similar).

I feel sorry for all the Arabs that are victims because of this. And I feel sorry for the many Israelis who actually did not vote for the current far-right sionist regime and its suicidal strategy.

That's what I thought. Thanks. The specification says that only 24 of the 28 lanes are available. Do you know why?

Hello!

I'm looking into buying a system for running inference with small to medium size LLM models. I wonder, is there any AM5 CPU + Chipset combination that supports 2x PCIe 16x with all lanes connected directly to the CPU? From what I've gathered my understanding is that there is no such configuration because the Ryzen 7000/9000 only have 24 PCIe lanes at best. This means I have to go for a Threadripper configuration, which is much more expensive. (The ROCm mGPU documentation states that all lanes shall be connected directly to the CPU.)

It's possible that I can manage running two GPUs with 8x lanes, but it's for sure not optimal..

But the thing is, it is quite hard for me to navigate the AMD website and the websites of various motherboard producers. I might very well be wrong.

So again: Is there any AM5 CPU + chipset combination that supports 2x PCIe 16x with all lanes connected directly to the CPU?

It is clear that the signal to noise ratio of the WWW is getting worse. It's much harder to find good content when using a good old search engine. And if it's good it is usually hosted on Reddit or Stackexchange.

So remember, even if it's easy too Google something (well, it isn't nowadays), we want to create a fediverse of good content that helps people (I hope). So, it's always better to write a real answer if you have the time and energy. Please help boost the SNR and reverse the AI fueled information degradation loop.
