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.

When you write programs in user space, the worst thing that can happen to your program is a core dump. Your program did something very wrong, so the operating system decided to give you all of its ...

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 ...

As with many Linux-related topics, the issue of using debuggers to troubleshoot the Linux kernel is not only technical--it's political. Linux is being mostly developed on the x86 platform, which does ...

Debugging the software in a complex real-time system is particularly challenging because the manifestation of a bug is frequently far removed from the actual occurrence of the bug-in both time and ...
