ASUS ROG Zephyrus G14 (2022) GA402

This page is applicable to the Asus ROG Zephyrus G14 GA402.

VFIO

The GPUs being muxed makes this laptop great for PCI Passthrough.

Kernel parameters can be set to bind vfio-pci to the discrete GPU.

rd.driver.pre=vfio-pci nogpumanager vfio-pci.ids=1002:73ef,1002:ab28

The GPU can then later be unbound from vfio-pci and rebound to AMDGPU later without disturbing the X11 session.

# echo 0000:03:00.0 > /sys/bus/pci/devices/0000:03:00.0/driver/unbind  
# echo 0000:03:00.1 > /sys/bus/pci/devices/0000:03:00.1/driver/unbind
# modprobe amdgpu
# echo 0000:03:00.0 > /sys/module/amdgpu/drivers/pci:amdgpu/bind 
# echo 1 > /sys/bus/pci/rescan

Power Management

See Power management, Laptop#Power management, AMDGPU#Power profiles

Suspend

Attempting to use s2idle occasionally crashes AMDGPU, resulting in artifacting.

A legacy s3 patch is available. See Power management/Suspend and hibernate#Changing suspend method.~

Wireless

Wi-Fi

The MediaTek MT7922 works with the MT7921e driver, but has oddly high ping times (~20ms for a single hop) with high variability (>2ms jitter). So it is functional, but has problems.

Some have recommended switching it out for the more popular and widely supported Intel Wi-Fi cards.

ASUS Linux

The ASUS Linux stack provides users of this laptop with a great many ASUS specific functions, to name a few:

• Battery Charge Limit,
• Multiplexer (GPU) Controls,
• Panel Overdrive,
• Much more.

It is highly recommended to install these tools for the optimal experience on these laptops.
