Cross instructions

These instructions cover:

1. building a cross toolchain
2. populating the new ROOT
3. making it chrootable using qemu-user to easily run "native" builds or tests (this is like a stage3 at the end)

You do not need to follow through to the end if you don't need a stage3-like root.

Set up the toolchain

Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work (NOT FOR QMK-BASED BOARDS)

Older Keychron keyboards (those not based on QMK) use the hid_apple driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.

Dealing with the Linux OOM Killer at the program level

Do this in cases when you dont want to change the os-level settings, but only want to disable the OOM killer for a single process. This is useful when youre on a shared machine/server.

The OOM killer uses the process level metric called oom_score_adj to decide if/when to kill a process. This file is present in /proc/$pid/oom_score_adj. The oom_score_adj can vary from -1000 to 1000, by default it is 0.

You can add a large negative score to this file to reduce the probability of your process getting picked and terminated by OOM killer. When you set it to -1000, it can use 100% memory and still avoid getting terminated by OOM killer.
