The 6.9 kernel is out

[Posted May 12, 2024 by corbet]

Linus has released the 6.9 kernel. "So 6.9 is now out, and last week has looked quite stable (and the whole release has felt pretty normal)." Significant changes in this release include the ability to create pidfds for individual threads, the BPF arena subsystem, the BPF token security mechanism, truncate() support in io_uring, support for the Rust language on 64-bit Arm systems, weighted interleaving in the memory-management subsystem, the device-mapper virtual data optimizer target, initial FUSE passthrough support, and more. See the LWN merge-window summaries (part 1, part 2) for more information.

Where can mere mortals buy this powerful ARM machine Linus is talking about?

They are mainly targeting server market, quick web search will give information.

It won't be long now. Lenovo has a couple of Snapdragon X laptops on the horizon, apparently. Pretty sure others will have them too. 🤞

Maybe something like the Asrock Rack Ampere Altra Bundle that newegg sells?

Those Ampere Altra boards actually seem a reasonable deal. The 128c Altra CPU with that board is getting better X/s/W than EPYC 9654 and 9754 on a number of benchmarks, according to Phoronix. Interesting.

I note there is a newer, higher core AmpereOne out. However, there don't seem retail boards and CPUs available?

I’d go ask Gigabyte of they already have something, which I think they do (they seem to be pretty close with Ampere, they were the first with Altra)

There’s a dev kit for Altra available (mobo + CPU) for a bit less than $2k - https://www.ipi.wiki/products/com-hpc-ampere-altra

The M1, M2 macbooks can run asahi linux.

My M1 runs great.

Linus says his M1 has been doing weekly builds, but the new machine does continuous builds, so it's not some Apple hardware. My experience with using Macbooks-as-CI is that they tend to cook themselves without some active cooling system (though the new machines may well be better; no one has yet donated one for CI usage ;) ). The Minis work well enough though.

Not sure about "buy", but Hetzner will lease you an 80-core ARM server for about $200 a month. (RX series)

Mandatory disclaimer: I am not sponsored by Hetzner. I happen to think they provide the best value-to-money ratio in dedicated and cloud hosting right now, and they also happen to offer something similar to what you are asking about.
