How to get kernel symbols and sources in Ubuntu?
The sources can be installed using the following command: Once the package is installed, go to /usr/src/linux-source- and unpack the source tarball: Now that you have both symbols and sources installed, you can use gdb to successfully debug your kernel.
Are there any non static symbols in the kernel?
The linking and invoking rules are much more stringent for modules than code in the core kernel image. Core code can call any non-static interface in the kernel because all core source files are linked into a single base image. Exported symbols, of course, must be non-static, too.
How does the Linux kernel header file work?
The Linux kernel header files provide a convenient way to manage the visibility of your symbols, thus reducing namespace pollution and promoting proper information hiding. The mechanism described in this section works with kernels 2.1.18 and later; the 2.0 kernel had a completely different mechanism, which is described at the end of the chapter.
How is module stacking implemented in the Linux kernel?
Module stacking is implemented in the mainstream kernel sources as well: the msdos filesystem relies on symbols exported by the fat module, and each input USB device module stacks on the usbcore and input modules. Module stacking is useful in complex projects.
How to install package that contains Ubuntu kernel debug symbols?
How to install a package that contains Ubuntu kernel debug symbols? The default Ubuntu kernel -generic package doesn’t seem to have symbols in it. I’m trying to avoid compile a kernel with debug info manually.
How to prepare a Linux machine for debugging?
This tutorial shows how to prepare your a Debian-based (e.g. Ubuntu, Mint) Linux machine for kernel debugging without rebuilding the kernel. Note that if you are using VisualKernel, this will be done automatically by the VisualKernel project wizard. This page provides instructions on doing it manually in order to help diagnosing common problems.
How big is the Linux kernel download size?
This is rather huge (>680MB), so prepare for a wait while you download it. I use the Linux kernel debug symbols for tools like systemtap on the kernel. I tried Colin Ian King ‘s answer and it did not work for me.
