After having to use Matrix for a while and seeing how bad Slack and Discord are, I wish there was a criminal law that would allow IRC only for IM. Steady performer, zero fucks. #IRC

After four weeks doing Rust it became clear to me that LSP is quite useful sometimes, when you have to deal with a language that was not designed to be written by humans.

[That said: even less so by Copilot, Bob or Clippy]

;-)

I've managed mostly with vim and rusty-tags so far but to help with code exploration I installed vscodium. Seems to do the job since it has a vim emulation plugin and works together with rust-analyzer. And LSP does not work too well in terminal anyhow...

PS. This is the most useful documentation that I found on topic: https://bootlin.com/pub/conferences/2020/elce/opdenacker-using-vs-code-for-embedded-development/opdenacker-using-vs-code-for-embedded-development.pdf

The end result:

I installed Asahi Linux to a 128 GB rootfs (out of 1 TB of internal storage). It is connected to a dock with an external 1 TB M.2 drive. Fedora sees this drive as /dev/sda.

Migrating the subvolume of /home was just a matter of creating a single all encompassing BTRFS partition to /dev/sda and then:

sudo btrfs device add /dev/sda1 /home -f
sudo btrfs device remove /dev/nvme0n1p6 /home -f

Now there is an airtight separation / and /home physically, and also they pool space only within their own cages.

Apple firmware supports only booting macOS from external storage, thus the rootfs must always reside in the internal storage, but I think this is already quite sustainable way to deal with it.

This bottleneck/policy can be mitigated but it does not pay the price. It can be overcome by installing macOS to an external storage and consuming internal storage in its full extent for Asahi Linux. Just mentioning this last for completeness ;-)

Encryption can/could be done by following https://davidalger.com/posts/fedora-asahi-remix-on-apple-silicon-with-luks-encryption/ with “a twist’ (since different partition/drive topology).

my friends have started to bully me as "jarkko.js" (those are my name letters). did not came to mind when picking username for my github account duh...

It's a start.

Since I guess Google knows Rust better than me I guess I'm doing the state of art with custom target JSON-files, i.e. deploying them to a random directory in the project directory :-)

I kind of hoped that there would be a place (let's say .cargo/targets or similar) under the project that gets automatically recognized by the tooling. Then you could just put that to rust-toolchain.xml like any other target.

@kernellogger I'm also going to try out your instructions, try to polish them and come up with something :-) I'll share the results when I have something. Compiling kernel is my thing (I guess) ;-)

@kernellogger Finding out what would be a sustainable approach to test kernel patches with a distribution kernel is already a conference presentation. If I was in Linux conference, would not miss that one. It is *rarely* covered topic.

Let’s imagine you want to do this in Rust:

#[link_section = ".note.jarkko"]

What is the default alignment?

#rust

@vathpela @kernellogger @securepaul Yeah all this helps! It's just before I take a few days and play with all these cool ideas that you and others kindly provided, anything I would right now would probably be uttermostly incorrect :-) Lot's of stuff to process. Thank you!

Laptop camera is not only bad but usually at home it is connected to an external display.

Have not really checked this through but what is keeping v4l2loopback out of upstream?

It's useful for instance using a phone as a webcam during meetings, which actually quite useful (because e.g. iPhone actually has a quality camera).

@vathpela @kernellogger @securepaul I'll revisit this thanks :-) Cannot really say but appreciate all this info. Now I need to digest all this for a while.
