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.

Kmemleak allows you to track possible memory leaks inside the Linux kernel. Basically, it tracks dynamically allocated memory blocks in the kernel and reports those without any reference left and that are therefore impossible to free.

In this post, I will show one more example of how easy it is to disrupt performance of a modern CPU, and also run a quick discussion on why performance matters - as well as present a few cases where it shouldn't matter.

Ever since Vulkan was announced a few years ago, the idea of creating a Vulkan benchmarking tool in the spirit of glmark2 had been floating in my mind. Recently, thanks to my employer, Collabora, this idea has materialized! The result is the vkmark Vulkan…

At Collabora one of the many things we do is build Debian derivatives/overlays for customers on a variety of architectures including 32 bit and 64 bit ARM systems. And just as Debian does, our OBS system builds on native systems rather than emulators.

Along with the usual load of memory leaks, crashes and other bugs, Collabora's multimedia team once again contributed a number of improvements across a wide number of areas.
Here are the events we'll be attending in the coming weeks – come say hello!
December 10-15, Vancouver, Canada
February 1-2, Brussels, Belgium
Whether writing a line of code or shaping a longer-term strategic software development plan, we'll help you navigate the ever-evolving world of Open Source.
