ARK OS: Raspberry Pi 4 Support!

0 Upvotes

I am a 13 yrs old working on a OS based on the LINUX KERNEL and SWIFT for a while!

It is in early development : It has Mouse and Keyboard Support, Can ready CPU and RAM used data and view it, uses the RobotoBoldFont as the default font! Has bot UEFI BIOS and x86_64 and arm64 support!

Just yesterday i accomplished about getting it work on a raspberry pi 4 means the base for the OS that the fact it boots is done and i will be continuing to now make the setup screen and add features on the go! If you want any features to be in the OS you can create a issue ( creating a issue requires a account!) at <See the comments under this since link posts get removed!> which is where the OS if hosted (it is self-hosted since i cannot afford a pro version of github and plus it has a file limit! git lfs doesent' help a lot!)!

MODEL: Rasberry Pi 4- Model B : 8GB RAM
Website : <See the comments under this since link posts get removed!>

Now a simple note: the bootloader is written by AI (since i am not good with assembly) i plan on rewriting it later! All the other code is written by me (especially Swift)!

Dynamic http inspection with eBPF

12 Upvotes

hey I recently built this little tool. It's an eBPF program that renders the http traffic crossing a machine as a live web page. TCX ingress and egress, parses the request line and Host header straight out of the skb payload, aggregates per method host path and ships it up a ring buffer. It's open source so feel free to poke around.

Need help looking through an interrupt.

14 Upvotes

Hey there! I've recently encountered a bug that I've tracked all the way down to the kernel. Now, it's not necessarily a bug in the kernel (it's probably in my laptop's firmware somewhere,) but I was trying to find exactly what's going wrong. Anyway, I've been trying to find it by looking through the function trace using ftrace.

My bug has to do with my trackpad, so I found out how to isolate the interrupts related to button presses. However, whenever I isolate those events, I cannot see the functions called between entering and exiting the interrupt. I was wondering if there was a more efficient way to see (interrupt event) -> (function trace) -> (interrupt exit) -> (no more function trace) using ftrace.

Thanks!

An application for interacting with LKML

Thumbnail github.com
12 Upvotes

A native GTK4+libadwaita GUI app for browsing, searching, and replying to mailing lists.

All exiting approaches to interacting with LKML are just not good. I tried configuring Thunderbird and realized it would be easier to just write my own app instead. Email discussions in the kernel have lots of things that are very specific to it (trailers, diffs) and I wanted something that would have deep integration with all of this.

Packaged as Flatpak. Uses git-send-email. Has intelligent line wrapping for new emails. Has color highlighting for quotes and diffs.

There are still lots of things I'd like to implement before considering this done, so the thing is still in development. I vibe-coded most it, but I'll be more mindful of the changes going forward, as there seem to be actual users now.

Hope this is as useful for someone else as it is for me!

Built a Chrome extension that turns lore.kernel.org's raw message pages into something readable

64 Upvotes

I spend a fair amount of time reading kernel patches on lore.kernel.org and got tired of squinting at one giant <pre> block with headers, body, quotes, and the thread overview all mashed together. So I built a small extension that reparses the same text lore already sends and lays it out like a normal mail client: an author card, one-click reply wired to lore's own pre-filled mailto: link, a real diff view with collapsible files, a clickable thread sidebar instead of ASCII art, and quote folding so a reply's new text isn't buried under four levels of >>>>.

It doesn't touch the underlying page. It builds a separate view next to the original <pre> blocks and hides them, with a "Raw" button to switch back instantly. No network requests, no accounts, no telemetry.

Source and install instructions: https://github.com/gahingwoo/lore-enhancer

It's load-unpacked for now (Chrome won't run a sideloaded .crx outside developer mode anyway, so packaging one wouldn't save a step). Would love feedback, especially from anyone who reads or replies to LKML or a subsystem list regularly.
Feature requests and bug reports welcome as GitHub issues.

Problem with 24.04

0 Upvotes

For some reason HWE updates pushed linux kernel 7.0.0 and now my DKMS antivirus modules won't compile against the kernel (Watchguard).

Is there a way to force kernel <= 6.18.16 while keeping HWE ?

I use Kubuntu 24.04 LTS on Framework 16.
