 = Linux Kernel Module Cheat
-:description: The perfect emulation setup to study and develop the <<linux-kernel>> v5.1, 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>>. "Tested" in an Ubuntu 18.04 host.

 In case something breaks while updating the Linux kernel, you can try to bisect it to understand the root cause: <<bisection>>.
 
+===== Update the Linux kernel LKMC procedure
+
+First, use use the branching procedure described at: <<update-a-forked-submodule>>
+
+Because the kernel is so central to this repository, almost all tests must be re-run, so basically just follow the full testing procedure described at: <<test-this-repo>>. The only tests that can be skipped are essentially the <<baremetal>> tests.

+Before comitting, don't forget to update:

+* the `linux_kernel_version` constant in link:common.py[]

 ==== Downgrade the Linux kernel
 
 The kernel is not forward compatible, however, so downgrading the Linux kernel requires downgrading the userland too to the latest Buildroot branch that supports it.
