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.

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.

Machine learning is increasingly seeing more applications and it's important to have FOSS options to accelerate such workloads. With that in mind, we began an effort earlier this year to get a TFLite model running on a VIM3 NPU using Etnaviv and OpenCL.

Earlier this year, I joined Collabora for a six-month internship to learn how V4L2 (Video4Linux2) supports stateless video hardware decoding, and build a utility that traced and replayed stateless decoding from a userspace perspective.

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.
Here are the events we'll be attending in the coming weeks – come say hello!
December 10-15, Vancouver, Canada
