# Linux Kernel Module Cheat
The perfect emulation setup to study and develop the <<linux-kernel>> v5.9.2, kernel modules, <<qemu-buildroot-setup,QEMU>>, <<gem5-buildroot-setup,gem5>> and x86_64, ARMv7 and ARMv8 <<userland-assembly,userland>> and <<baremetal-setup,baremetal>> assembly, <<c,ANSI C>>, <<cpp,C++>> and <<posix,POSIX>>. <<gdb>> and <<kgdb>> just work. Powered by <<about-the-qemu-buildroot-setup,Buildroot>> and <<about-the-baremetal-setup,crosstool-NG>>. Highly automated. Thoroughly documented. Automated <<test-this-repo,tests>>.

## 27. Userland content

This section documents our test and educational userland content, such as C, C++ and POSIX examples, present mostly under userland/.

Getting started at: Section 2.8, “Userland setup”

Userland assembly content is located at: Section 28, “Userland assembly”. It was split from this section basically because we were hitting the HTML `h6` limit, stupid web :-)

This content makes up the bulk of the userland/ directory.

The quickest way to run the arch agnostic examples, which comprise the majority of the examples, is natively as shown at: Section 2.8.2.1, “Userland setup getting started natively”
