                Install Ubuntu 18.04 on Lenovo T14s AMD with Ryzen 7 PRO 4750U CPU and AMD Renoir GPU
              
          
    Ubuntu 18.04 on Lenovo T14s

What's the problem?

The Ryzen CPU and Renoir GPU are too new for all kernels supported by Ubuntu 18.04 (5.4 is the latest supported). The notebook will boot with 18.04.5, but a lot of things will not work (sleep, screen brightess, audio, graphics only works in a limited way etc.).
This tutorial shows the steps necessary to be done to successfully run the system with full support for the GPU and other peripherals.

## ptp_test.py
"""
This is a script for testing whether a switch fills the correction field in relevant PTPv2 messages.
The following combinations of message types and two-step clock should get the correction field filled:
|       TYPE       | 2-STEP |
| SYNC             | 0      |
| DELAY_RESP       | -      |
| FOLLOW_UP        | -      |
| PDELAY_RESP      | 0      |
| PDELAY_FOLLOW_UP | -      |
I.e. SYNC and PDELAY_RESP with TWO_STEP=1 can have zero correction.

## sync_watch.py
"""
This program continuously checks whether a PTP client is well synced to its master.
