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.

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.

After fighting with the divide between implicit and explicit synchronization with Vulkan on Linux for over seven years, we may finally have some closure. We're not to synchronization nirvana quite yet, but this is an important step along the way.

Optical hand tracking for XR has a bit of a reputation - getting training data, training neural nets, and deploying them in real-time, low-latency environments such as XR is every bit as hard as they say it is.

When developing an application or a library, it is very common to want to run it without installing it, or to install it into a custom prefix rather than on the system. Here's how Meson can help with that.

An incredible amount has changed in Mesa and in the Vulkan ecosystems since we wrote the first Vulkan driver in Mesa for Intel hardware back in 2015. Not only has Vulkan grown, but Mesa has as well.

Until now, no Valhall devices (Mali-G57, Mali-G78) ran mainline Linux - whilst this made driver development obviously difficult, there’s no better time to write drivers than before the devices even get into the hands of end users.
