Testing Video4Linux2 drivers like a boss

May 23, 2019 by Ezequiel Garcia  |   Blog

With virtme, you can run a custom built kernel on top of our running root filesystem. In this post, we explore another example of virtme in action, and see how to test Video4Linux2 drivers on bleeding edge GStreamer builds.

An eBPF overview, part 5: Tracing user processes

May 14, 2019 by Adrian Ratiu  |   Blog

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 buffer flow analyzer

April 25, 2019 by Guillaume Desmottes  |   Blog

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.

An introduction to Linux kernel initcalls

July 14, 2020 by Mylène Josserand  |   Blog

Initcalls, which serve to call functions during boot, were implemented early on in the development of the Linux Kernel. Read on as we take a closer look, including their purpose, their usage, ways to debug them (using initcall_debug or FTrace), and more.

Using regmaps to make Linux drivers more generic

May 27, 2020 by Adrian Ratiu  |   Blog

Device drivers can support more revisions and SoC platforms by abstracting away specific hardware interface layouts. Let's examine a specific instance of this process, namely the effort to make the MIPI DSI host controller driver more generic.
