rtw89 VS RyzenAdj

I found this GitHub link that contains instructions on how to compile the driver for most distributions. However, they require usage of make install so I don't think that would work on NixOs.

I have the older version with the 6900HS but it’s more or less the same. I’ve run pop_os as well as fedora on it. Everything works great but you’ll have to compile the wifi driver https://github.com/lwfinger/rtw89.

I have seen other people with newer Lenovo systems reporting success with this: https://github.com/lwfinger/rtw89/blob/main/README.md

This is a Realtek rtl8852be chipset and uses the rtw89 driver which does not come prepackaged in the Linux kernel... See https://github.com/lwfinger/rtw89

Got mine working on a fresh Ubuntu 22.04 with 7 commands: sudo apt update && sudo apt upgrade sudo apt install make gcc build-essential git git clone https://github.com/lwfinger/rtw89.git cd rtw89 make sudo make install sudo reboot 0

Yes I guess, its already been reported in earlier versions. I tried to install from code, https://github.com/lwfinger/rtw89 But it didn't work either.

Realtek drivers are such a PITA. Check out this guys Github: Link he has instructions on how to get the most common realtek chipsets working. Please note, kernel updates will break the drivers for all realtek workarounds and you will have to redo this after each update.

but to my understanding, it cannot be installed due to kernel related issues. so i tried installing this instead with no luck: https://github.com/lwfinger/rtw89

apt-get install make gcc linux-headers-$(uname -r) build-essential git Install 'fix': git clone https://github.com/lwfinger/rtw89.git -b v5 cd rtw89 && make && sudo make install load module: sudo modprobe rtw89pci

git clone https://github.com/lwfinger/rtw89.git -b v5 cd rtw89 && make && sudo make install

Out of curiousity how the 7840HS performs at different TDP, I did some benchmarks using Geekbench 6.2.0. To change the TDP, I've used the software RyzenAdj like so:

TLDR: Ryzen Adj.

A few years ago I did a bunch of poking w/ a 4800H, you can see the actual mechanics of using RyzenAdj. There are also Geekbench 5 benchmarks linked from the doc at different power limits which you can compare to 4800U devices on Geekbench's site: https://github.com/lhl/linuxlaptops/wiki/2020-MECHREVO-Code-...

Note, each laptop manufacturer may choose their different power limits (and like Intel, AMD's curves are largely driven by temperature, so dependent on cooling solution and other settings).

This is a good summary of some of how Ryzen Mobile's power limiting works (actually, read that whole wiki if you're interested in the topic): https://github.com/FlyGoat/RyzenAdj/wiki/Renoir-Tuning-Guide

I'd also look up "AMD PMF" (their equivalent of DPTF) which only recently made it's way to the Linux kernel (but of course, that will include loads of details anyone can look through): https://www.phoronix.com/news/AMD-PMF-CnQF-Linux-6.1
