Heaptrack v1.1.0 release Better memory profiling on Linux

After more than a year of work, I’m pleased to release another version of heaptrack, the Linux memory profiler! The new version 1.1.0 comes with some new features, significant performance improvements and – most importantly – much improved stability and correctness. If you have tried version v1.0 in the past and encountered problems, update to […]

Qt Quick without a GPU: i.MX6 ULL on small embedded devices

  With the introduction of the Qt Quick software renderer it became possible to use Qt Quick on devices without a GPU. We investigated how viable this option is on a lower end device, particularly the NXP i.MX6 ULL. It turns out that with some (partially not yet integrated) patches developed by KDAB and The […]

I have used it extensively and successfully on various customer projects, both for desktop applications as well as automotive or industrial projects targeting low-end embedded Linux targets running on ARM hardware. The biggest problem with perf really is its usability, […]

It allows you to visually analyze perf.data files with the built-in Flame Graph and the Bottom-Up, Top-Down, or Caller-Callee data tables. It is a […]

Profiling QtQuick HMI Performance on Embedded Linux by Thomas McGuire

QtQuick is a popular choice for creating HMIs for embedded devices. The hardware on these devices is often constrained and less performant than their desktop equivalents, this requires extra care from software developers in delivering a fluid user experience. KDAB is regularly involved in improving the performance of QtQuick HMIs on such devices for their […]
