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 ...

Hey all. I was wondering if you know of any debugging, tracing, benchmarking, monitoring etc. tools that are available for kernel modules. I basically want to be able to monitor what a kernel module ...

The Linux Kernel is written in C programming language, so C is the most important language for the Linux Kernel developer. Initially, the kernel was written in GNU C (now it is also possible to build ...

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 ...

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 ...

Your new project really could use a block device for Linux. File systems are easy to do with FUSE, but that’s sometimes too high-level. But a block driver can be tough to write and debug, ...

I'm no code sleuth, but I fear that I may be getting a bit of a runaround from a tech support person. I feel I need to run the kernel debugger on a minidump to see if I can confirm whether or not ...
