It used to be that building the Linux kernel was not easy. Testing and debugging were even worse. Nowadays, it is reasonably easy to build a custom kernel and test or debug it using virtualization.

Kernel debugging systems can slow the kernel enough to hide or change the bugs they’re looking for. A new tracing system would minimize the performance penalty of running with tracing on. LTTng relies ...

Kernel drivers are the bridge between the Linux operating system and the hardware components of a computer. They play a crucial role in managing and facilitating communication between the OS and ...
