Help text

If you say Y here the resulting kernel image will include debugging info resulting in a larger kernel image. Say Y here only if you plan to use gdb to debug the kernel. Please note that this option requires new binutils. If you don't debug the kernel, you can say N.

Compile the kernel with debug info found in lib/Kconfig.debug

The configuration item CONFIG_DEBUG_INFO:

Help text

If you say Y here the resulting kernel image will include debugging info resulting in a larger kernel image. This adds debug symbols to the kernel and modules (gcc -g), and is needed if you intend to use kernel crashdump or binary object tools like crash, kgdb, LKCD, gdb, etc on the kernel. Say Y here only if you plan to debug the kernel.

If unsure, say N.

Enable kernel debugging symbols found in arch/um/Kconfig

The configuration item CONFIG_DEBUG_INFO:

Help text

When this is enabled, the User-Mode Linux binary will include debugging symbols. This enlarges the binary by a few megabytes, but aids in tracking down kernel problems in UML. It is required if you intend to do any kernel development.

If you're truly short on disk space or don't expect to report any bugs back to the UML developers, say N, otherwise say Y.

Include GDB debugging information in kernel binary found in arch/arm/Kconfig.debug

The configuration item CONFIG_DEBUG_INFO:

Help text

Say Y here to include source-level debugging information in the `vmlinux' binary image. This is handy if you want to use gdb or addr2line to debug the kernel. It has no impact on the in-memory footprint of the running kernel but it can increase the amount of time and disk space needed for compilation of the kernel. If in doubt say N.
