Linux (Fedora 35) on a Thinkpad P14s [T14] Gen2 AMD

These are my installation-tricks and notes for running Linux on a 2021 Thinkpad P14s Gen2 with AMD Ryzen 7 5850U. It should also be suitable for the Thinkpad T14 Gen2 AMD as they are technically the same modell.
Meanwhile there is also a good test on youtube and an entry in the arch-wiki, which also comments some points mentioned here.

If you run VMware Workstation 11 or above you may encounter high CPU usage from process khugepaged on Ubuntu 15.04+

The fix is to disable transparent hugepages. It seems Ubuntu has it enabled by default.

You can check the current status on your system by running:

cat /sys/kernel/mm/transparent_hugepage/enabled

cat /sys/kernel/mm/transparent_hugepage/defrag

The natural way to start with CUDA

The natural way to start with CUDA if you plan to be self taught is:

1. CUDA by Example: An Introduction to General-Purpose GPU Programming by Jason Sanders and Edward Kandrot Nice introduction. It is more like playing with your GPU and admire its capabilities.

2. Programming Massively Parallel Processors, Second Edition: A Hands-on Approach by David B. Kirk and Wen-mei W. Hwu It explains a lot of things in GPU Programming. You simply can't go without it.
