Improving GNOME Wayland Performance on Ubuntu 22.04: Enhancing Responsiveness for GTK and Qt5 Applications
The Linux desktop has gone through many evolutionary stages, but few transitions have been as significant as the move from the traditional Xorg windowing system to Wayland. Ubuntu 22.04, one...
Power Management and CPU Frequency Scaling in Linux
In modern computing, particularly in Linux-based environments, power management and CPU frequency scaling have become indispensable areas of focus. The demands of energy efficiency, thermal control, battery longevity, and performance...
Migrating from Xorg to Wayland in Linux
In the ongoing evolution of Linux graphics stacks, one of the most transformative transitions that the community is actively engaged in is the migration from Xorg to Wayland. For decades,...
Real-Time Video Processing Pipelines with V4L2, DRM/KMS, and Hardware Encoders in Linux
Real-time video processing on embedded Linux platforms has evolved from a niche requirement for high-end multimedia systems into a core necessity for modern edge devices, surveillance systems, automotive infotainment units,...
Using OpenCL and GPU Acceleration in Embedded Linux for Edge AI/ML Inference
In the evolving landscape of embedded systems, the demand for executing sophisticated artificial intelligence and machine learning models directly on the edge has never been higher. Whether it is a...
Tracing System Calls in Embedded Applications with strace, ltrace, and auditd in Linux
When working with embedded Linux platforms, especially those running mission-critical applications, understanding what your software is doing beneath the surface is not a luxury—it’s a necessity. In the embedded space,...
Kernel Lockup Debugging: Detecting Deadlocks and Softlockups in Custom Drivers in Linux
The Linux kernel is often celebrated for its robustness, its scalability across hardware—from the tiniest embedded boards to the largest supercomputers—and its rich ecosystem of drivers supporting an enormous range...
Diagnosing Boot Time Delays with Bootchart, systemd-analyze, and U-Boot Timestamps in Linux
The boot process of a Linux-based system is often perceived as a simple, linear chain of events — the power is applied, the bootloader runs, the kernel initializes, the init...
Thermal Zones and Dynamic CPU Frequency Scaling on Embedded Linux Platforms
Thermal management on embedded Linux platforms is not simply a matter of preventing overheating; it is a highly integrated balancing act involving hardware design, kernel subsystems, and runtime performance control....
Memory Fragmentation, CMA (Contiguous Memory Allocator), and DMA Buffer Management
Under Linux, memory management is a complex orchestration that balances performance, predictability, and fairness, and one of the most intricate challenges faced in kernel memory allocation is handling memory fragmentation,...
