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.

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.

Running crosvm outside Chromium OS is quite easy, with the only complication being that minijail isn't widely packaged in distros. In these instructions, we hack around the issue with linker environment variables so we don't have to install it properly.

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.
