Navigate through the kernel features and menuconfig commands. Esc+Esc: Exit menuconfig or cancel the command. ↵ Enter: Activate a command, or expand a branch. y: Compile and include this feature inside of the kernel. m: Compile this feature as a module, separate from the kernel. n: Do not compile the feature. / Search configuration parameter.
Buildroot is a set of Makefiles and patches that simplifies and automates the process of building a complete and bootable Linux environment for an embedded system, while using cross-compilation to allow building for multiple target platforms on a single Linux-based development system.
The Linux from Scratch project, like BitBake, also supports cross-compiling Linux for ARM embedded systems such as the Raspberry Pi and BeagleBone. [ 7 ] [ 8 ] The book Hardened Linux From Scratch (HLFS) focuses on security enhancements such as hardened kernel patches, mandatory access control policies, stack-smashing protection , and address ...
Tab ↹[command 1] . . . Tab ↹[command n] Usually a rule has a single target, rather than multiple. A dependency line may be followed by a recipe: a series of TAB indented command lines that define how to generate the target from the components (i.e. source files). If any prerequisite has a more recent timestamp than the target file or the ...
The Linux kernel and GNU C Library together form the Linux API. After compilation, the binaries offer an ABI . The glibc project was initially written mostly by Roland McGrath, working for the Free Software Foundation (FSF) in the summer of 1987 as a teenager.
Linaro is an engineering organization that works on free and open-source software such as the Linux kernel, the GNU Compiler Collection (GCC), QEMU, power management, graphics and multimedia interfaces for the ARM family of instruction sets and implementations thereof as well as for the Heterogeneous System Architecture (HSA).
Loadable kernel modules in Linux are loaded (and unloaded) by the modprobe command. They are located in /lib/modules or /usr/lib/modules and have had the extension .ko ("kernel object") since version 2.6 (previous versions used the .o extension). [5] The lsmod command lists the loaded kernel modules.
This allows drivers and devices outside of the mainline kernel to continue working after a Linux kernel upgrade. [3] Another benefit of DKMS is that it allows the installation of a new driver on an existing system, running an arbitrary kernel version, without any need for manual compilation or precompiled packages provided by the vendor.
