# Debugging linux kernel

At a high level, you can categorize issues in the kernel space as kernel panic and bugs. To debug kernel-space issues, you can use the logs, command line tools, and dumps shown in the following figure:

* Logs section includes dynamic debug, kernel debugging configuration, and function tracer
* Command-line tools provide access to the `/proc` and `debugfs` file systems
* Dumps section lists RAM dump, RAM parser, and crash utility that are used for analyzing system crashes and memory states

You can generate kernel logs using the `dmesg` command.

To debug issues in the kernel space, it's recommended to use the `debug` build. For more information about how to generate the `debug` build, see [Qualcomm Linux metadata layers overview](https://dragonwingdocs.qualcomm.com/Key-Documents/Yocto-Guide/qualcomm-linux-metadata-layers#qualcomm-linux-metadata-layers).

For more information about kernel source configuration files, see \[Qualcomm Linux Kernel Guide([https://dragonwingdocs.qualcomm.com/System/Kernel/kernel-overview](https://dragonwingdocs.qualcomm.com/System/Kernel/kernel-overview)).
