Qualcomm QUPv3 Firmware Upstreamed For Snapdragon X1 Elite Linux Users
One of the headaches right now when dealing with the Snapdragon X Elite on Linux is that for a majority of the devices you need to fetch firmware files from the Windows 11 on ARM partition as the necessary firmware bits for Linux use aren’t upstreamed to linux-firmware.git. That has gradually improved over time from the qcom-firmware-extract making the process easier to more firmware bits eventually being added to linux-firmware.git… ⌘ Read more

@prologic@twtxt.net (While browsing through that, I noticed that https://mu-lang.dev/ itself doesn’t really mention the source code repo, does it? 🤔 Like, the quickstart guide begins with “Build the host: go build ./cmd/mu”, but where’s the git clone … command? 😅)

I’m not really sure what the goal is. 🤔 Do you want to get pull requests for the docs? Or bug reports for mu itself? 🤔

Revisiting The Linux 6.19 Performance With “NEXT_BUDDY” Now Disabled
Back at the start of the Linux 6.19 kernel cycle I ran benchmarks showing some scheduler performance regressions with the new kernel. Fortunately, two weeks out from the Linux 6.19 stable release, merged this weekend was disabling the scheduler’s NEXT_BUDDY feature due to performance regressions. Here are some fresh benchmarks looking at the latest Linux 6.19 Git state with/without NEXT_BUDDY and comparing it to Linux 6.18 stable for reference. ⌘ Read more

Some Meaningful Performance Benefits For Clang + LTO Built Linux Kernels
Over the past few years building the Linux kernel with Clang has matured a lot thanks to upstream improvements to both LLVM/Clang and the Linux kernel. As it’s been a while since our last comparison for GCC vs. Clang built kernels on the resulting system performance, our latest year-end 2025 benchmarking is providing a fresh look at the Linux 6.19 upstream Git kernel built under the latest stable GCC 15 and LLVM Clang 21 compilers. Plus … ⌘ Read more

@shinyoukai@neko.laidback.moe Because you might not want to commit all changed files in a single commit. I very often make use of this and create several commits. In fact, I like to git add --patch to interactively select which parts of a file go in the next commit. This happens most likely when refactoring during a feature implementation or bug fix. I couldn’t live without that anymore. :-)

If you have a much more organized way of working where this does not come up, you can just git commit --all to include all changed files in the next commit without git adding them first. But new files still have to be git added manually once.

Why the hell do I have to git add everything!? Is it not enough for the file(s) to be already checked in from the get go?

Git = G(od damn)it

I just had a closer look at https://git.mills.io/prologic/mu and it motivated me to do some compiler building myself again. Hopefully, I find some time in the next free days. I’m bad at it, but it’s always great fun.

@movq@www.uninformativ.de @kiwu@twtxt.net it just so happens to be a happy coincidence that I’m extending mu’s capabilities to now include a native toolchain-free compiler (doesn’t rely on any external gcc/clang or linkers, etc) that lowers the mu source code into an intermediate representation / IR (what @movq@www.uninformativ.de refers to as “thick layers of abstractions”…) and finally to SSA + ARM64 + Mach-O encoder to produce native binary executables (at least for me on my Mac, Linux may some later?) 🤣

Yet another free software web git interface going behind a paywall thanks to all the “AI bots” trying to kill the small web. Just great.

I cleaned up all my of AoC (Advent of Code) 2025 solutions, refactored many of the utilities I had to write as reusable libraries, re-tested Day 1 (but nothing else). here it is if you’re curious! This is written in mu, my own language I built as a self-hosted minimal compiler/vm with very few types and builtins.

@lyse@lyse.isobeef.org My theory is that these people simply don’t do “code archeology”. When something breaks, they don’t reach for git log. They simply don’t experience the pain that comes with bad commits / commit messages.

@bender@twtxt.net yeah, I’ve been reading through the documentation last night and it felt overwhelming for a minute… +1 point goes to GTS’s docs. but hey, I’ll be taking the easy route: podman-compose up -d they provide both a container image and an example compose file in a separate git repo but I’m wondering why that is not mentioned anywhere in the docs, (unless it is and I haven’t seen it yet)
