I wrote these instructions as part of "installing PyTorch with CUDA 12.1.1".
I extracted them into this separate gist, because I realised there's a much easier way to install magma for CUDA 12.1.1:
https://anaconda.org/pytorch/magma-cuda121

There's a conda package!

conda install -c pytorch magma-cuda121

Disable or uninstall the official C/C++ plugin.
Install the clangd plugin.
Build the kernel with clang:

/path/to/kernel_source$ make CC=clang defconfig
/path/to/kernel_source$ make CC=clang -j16

Generate the compile_commands.json:

/path/to/kernel_source$ python ./scripts/clang-tools/gen_compile_commands.py

Requirements

[swayidle][]
[swaylock][]
any shell supporting sh syntax and execution of tasks in the background (job control is not necessary); just make sure that you fix the path to the shell at the top of the script if it isn't /bin/sh

Installation

Resize Ghidra for High DPI screens

If you run Ghidra on a high DPI screen, you will probably find the GUI to be scaled down so small to be almost of no use.

There is a setting that you can adjust to scale the Ghidra GUI:

in $GHIDRA_ROOT/support is a file named launch.properties. In this launch.properties file is the following configuration key:

VMARGS_LINUX=-Dsun.java2d.uiScale=1

How to GDB android native libraries

[1] Install NDK from android studio

[2] Push appropriate gdb-server to phone

adb push ~/android-sdk-linux/ndk-bundle/prebuilt/android-<arch>/gdbserver/gdbserver /data/local/tmp
adb shell "chmod 777 /data/local/tmp/gdbserver"
adb shell "ls -l /data/local/tmp/gdbserver"

[4] Forward ports

adb forward tcp:1337 tcp:1337

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead

Example

Getting access token

Enable developer console in browser and navigate to:

https://www.facebook.com/v2.6/dialog/oauth?redirect_uri=fb464891386855067%3A%2F%2Fauthorize%2F&scope=user_birthday%2Cuser_photos%2Cuser_education_history%2Cemail%2Cuser_relationship_details%2Cuser_friends%2Cuser_work_history%2Cuser_likes&response_type=token%2Csigned_request&client_id=464891386855067&ret=login&fallback_redirect_uri=221e1158-f2e9-1452-1a05-8983f99f7d6e&ext=1556057433&hash=Aea6jWwMP_tDMQ9y

Look for the response of POST request in the network tab of developer console: https://www.facebook.com/v2.6/dialog/oauth/confirm?dpr=1 it contains the access token parameter. Just search for 'access_token' in the response. For the lazy people (like myself) i made a small helper that parses the token from response https://taseppa.github.io/tokenparser.github.io/
