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.

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.

My work on Wayland and Weston color management and HDR support has been full of learning new concepts and terms. Many of them are crucial for understanding how color works, and what the values in a pixel actually mean.
