Introduction

In this article, we will discuss the issue of being unable to get power delivery working on Arch Linux, specifically when the kernel version is 6.9.7-arch1. We will cover the key concepts related to this problem and provide a detailed context to help you understand and resolve the issue.

Understanding Power Delivery in Linux

Power delivery is a critical component of any modern computing device, and it is managed by the operating system's kernel. In Linux, power delivery is handled by the Power Delivery (PD) protocol, which is a part of the USB Type-C specification. The PD protocol enables devices to negotiate power delivery over a USB Type-C connection, allowing for fast charging and power delivery to peripherals.

PD Protocol in Arch Linux

Arch Linux is a popular Linux distribution known for its simplicity and minimalism. The PD protocol is implemented in Arch Linux through the use of the linux-firmware package, which contains the firmware required for various devices, including those that use the PD protocol. However, in some cases, the PD protocol may not work as expected, causing issues with power delivery.

Troubleshooting Power Delivery Issues in Arch Linux

If you are unable to get power delivery working in Arch Linux, there are several steps you can take to troubleshoot the issue. In this section, we will cover some of the key steps you can take to resolve the issue.

Check the Kernel Version

The first step in troubleshooting power delivery issues in Arch Linux is to check the kernel version. As mentioned earlier, the issue in this article is related to the kernel version 6.9.7-arch1. If you are running this kernel version, it is possible that the issue is related to a bug in the kernel.

Update the Kernel

If you are running an older kernel version, it is recommended that you update to the latest version. This can be done by running the following command:


sudo pacman -Syu linux

This will update the kernel to the latest version available in the Arch Linux repository.

Check the Power Delivery Firmware

If updating the kernel does not resolve the issue, the next step is to check the power delivery firmware. The power delivery firmware is contained in the linux-firmware package. To ensure that the latest firmware is installed, run the following command:


sudo pacman -Syu linux-firmware

This will update the power delivery firmware to the latest version available in the Arch Linux repository.

Check the Power Delivery Device

If the power delivery firmware is up to date, the next step is to check the power delivery device. This can be done by running the following command:


lsusb -t

This will display a tree view of all USB devices connected to the system. Look for the power delivery device and ensure that it is properly connected and recognized by the system.

In this article, we have discussed the issue of being unable to get power delivery working in Arch Linux, specifically when the kernel version is 6.9.7-arch1. We have covered the key concepts related to this problem and provided a detailed context to help you understand and resolve the issue. By following the steps outlined in this article, you should be able to troubleshoot and resolve power delivery issues in Arch Linux.
