Pine fun - How low can we go...
One of the most pressing practical concerns of mobile phones is battery lifetime. We wondered, what can we expect from a Genode-based PinePhone? To find out, we took our custom SCP firmware as instrument to poke all the dials and knobs and we could find deep in the device. Continue...

Performance analysis made easy
Identifying performance bottlenecks of Genode's low-level system components remains a tedious effort. For this reason, it is usually not practiced as a routine during development but only under strong pressure. Conversely, performance optimizations may be implemented without evidence for their presumed effect, increasing complexity for rather intangible benefits. Now a new utility presented in this posting comes to the rescue. Continue...

A C++ inlining anecdote
During my recent work on the management component of Sculpt OS, the compile time of this particular component started to bother me. Moreover, the size of the resulting binary raised my eyebrows. So I took a closer look. Continue...

Micro benchmarks - what can possibly go wrong
From time to time I need to compare execution times and memory throughput in between Genode's hw-kernel and the baseline (typically using Linux) regarding one of the hardware platforms supported by Genode. Mostly this is done when the hw-kernel is ported to new hardware, or we experience unusual workloads on a platform, like recently when investigating a non-working USB driver on Raspberry Pi 1. Continue...
