Up until now, talking in-depth about userspace tracing was deliberately avoided because it merits special treatment, hence this part devoted to it. We'll now look at the why of it, and we'll examine eBPF user tracing in two categories: static and dynamic.

Now that we've studied the mainstream way of developing and using eBPF programs on top of the low-level VM mechanisms, we'll look at projects taking different approaches, attempting solutions to some of the unique problems faced by embedded Linux.

In part 1 and 2 of this series, we took a condensed in-depth look at the eBPF VM. In part 3, we define the high-level components of an eBPF program, including the backend, loader, frontend and data structures.

GStreamer's logging system is an incredibly powerful ally when debugging but it can sometimes be a bit daunting to dig through the massive amount of generated logs. I often find myself writing small scripts processing gst logs when debugging.

A well-known Linux kernel developer once said, a poor craftsman famously complains about his tools, but a good craftsman knows how to choose excellent tools. Here's a python-based tool that integrates git and patchwork, and can greatly improve your toolbox.

The second part of this series takes a more in-depth look at the eBPF VM and program studied in the first part. Having this low level knowledge is not mandatory but can be a very useful foundation for the rest of the series.

Rust is a modern language known for its memory safety, efficiency, and wide range of high-level features. But many beginners also run into something else in Rust: how surprisingly difficult it is to represent some common designs.

I have been working on getting U-boot upstream up to speed for the Radxa Rock-5B Rockchip RK3588 board. One of the cool features that I recently published upstream is the ability to boot the board without any kind of non-volatile media (NVM) used.

I previously talked about getting the bigger brother Rock 5B into mainline U-boot; this time I worked on the Rock 5A, an even tinier SBC based on Rockchip's RK3588S SoC that is one step closer to getting accepted.

Contrary to traditional software development, data is more important than code in machine learning. Building a high-performing model requires using reliable, precisely labelled data but poor-quality data is not always obvious.

A while back I presented USB 2.0 host support that was added to U-boot for the Radxa Rock-5B RK3588 Rockchip board. This time, USB 3.0 was added with support for the host and gadget.

Work continues on the Radxa ROCK5B RK388, as PCIe and RTL8125B networking support in U-boot have now been added. Publishing code as Open Source can benefit many different other projects, and allows anyone to benefit.
