How to get the config file for compiling the kernel?
There may be more than one, in which case use the command uname -r to tell which kernel you’re currently running, and then you can use the appropriate config. If your running kernel was compiled with the CONFIG_IKCONFIG_PROC option, you can get the config in /proc/config.gz:
Is it possible to configure the Linux kernel?
Kernel configuration is possible via a user interface which allows you to select the features that you want include in the new kernel. We will also make some additional changes for documentation purposes. To start, change the current directory to the root of the linux source tree (given above).
Do you need to make make menu config?
It is not recommended just a bare make menuconfig. The required config depends on three things: See also Kernel configuration for distributions. The first paragraph: Configuring a kernel was once a fairly straightforward process, only requiring knowledge of what hardware needs to be supported.
Why did my defconfig kernel failed to boot?
Your defconfig kernel probably failed to boot because of that. “defconfig” is usually pegged at the commonly used hardware – x86, or x86_64, and perhaps not so recent chipset or motherboard.
How to compile Linux kernel to local version?
Run this from your kernel source folder “cp /boot/config-`uname -r` .config”. This saves a lot of time, but you may want to change version number of the to be compiled kernel to avoid replacing your current kernel. “General setup” –> “Local version – append to kernel release”.
Do you need the kernel compiled in a special way?
You need the kernel compiled in a special way, that the official kernel is not compiled in (for example, with some experimental feature enabled). You are attempting to debug a problem in the stock Ubuntu kernel for which you have filed or will file a bug report.
How to make the Linux kernel the default?
The kernel downloaded is the latest stable one from kernel.org. We let the defaults remain (make no changes) in the options of make menuconfig. Simply type make, make install, grub-update, and reboot.
Where is the source code of the Linux kernel?
The Linux kernel source code is mostly written in C and assembly language. It is located in the directory /usr/src/kernel/linux-x.y.z, where x.y.z indicate the kernel release (version). The kernel version in the current release is 2.6.18. The y number of this code is particularly interesting.
How are kernels compiled and installed in Debian?
Introduction and Prerequisites Unsurprisingly Debian manages the kernel in the form of a package, which is not how kernels have traditionally been compiled and installed. Since the kernel remains under the control of the packaging system, it can then be removed cleanly, or deployed on several machines.
