The MSI GS75 Stealth (9SF) is an Intel architecture American Megatrends Inc. notebook with an Intel i7-9750H CPU and an NVIDIA Turing 20XX Q GPU.

- HDMI ports are directly wired to the dedicated GPU, Thunderbolt Type-C is not.
- The Intel integrated GPU (iGPU) is directly wired to the notebooks screen (EDP-1).
- The NVIDIA GPU (dGPU) is directly wired to the external HDMI port.
- Thunderbolt is wired to its own controller, but is somehow attached to the power state of the NVIDIA GPU.
- Thunderbolt firmware can be updated via BIOS, but the process is dangerous and can brick the machine.
- Native Microphone comprises two mono microphones that need to be managed for stereo-input and noise reduction.

## Installation

It is best to to enable factory default settings in the UEFI before installing. This will disable Secure Boot and provide sane settings for the CPU/GPU/PCH/EC. Resetting is not required, but this suggestion exists due to the complexity of advanced options and the configuration of PCIe on this model.

## Firmware

- Enter UEFI configuration: `Del`
- Select BOOT Device: `F11`

The default UEFI menu does not expose all possible options, to do so you must enable the "Advanced BIOS" feature:

- Enter "Advanced BIOS": `LAlt+F2+RShift+RCtrl`

### fwupdate

MSI provides firmware binaries for both the UEFI and Embedded Controller (EC). These files can be found at https://www.msi.com/Laptop/GS75-Stealth-9SF/support .

System firmware (EC) can be update via `fwupd`, but the UEFI cannot.

## Keyboard

### Backlight

Keyboard brightness works out of the box with `Fn+NumPadMinus/Plus`.

The lights on the keyboard cannot be configured with msi-keyboard-gitAUR, because this tool only works with region-based RGB lighting. For this laptop model, the tool msi-perkeyrgbAUR provides partial control.

### Function keys

The airplane mode key combination (`Fn+F10`) is disabled by default. Adding the following kernel parameters activates airplane mode key combination:

    acpi_osi=! acpi_osi="Windows 2009"

## Touchpad

Multi gestures do not work out the box, but are detected with libinput-gesturesAUR.

## Thermals

Control the fans with iswAUR. It will only work after enabling `ec_sys write-support` by adding the following to your kernel command line:

    ec_sys.write_support=1

## Microphone

This notebook has a microphone array which provides stereo input. Noise reduction, echo cancellation, noise suppression can all be done via beamforming. To get the best of it add:

    /etc/pulse/default.pa

    load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args="beamforming=1 mic_geometry=-0.025,0,0,0.025,0,0"
    set-default-source alsa_input.pci-0000_00_1f.3.analog-stereo.echo-cancel
