howdy VS isw

you can even use facial recognition with IR webcam

I just bought a go 2 (not laptop go) this weekend and installed fedora 37 on it. Almost everything worked without the surface kernel except the camera requires v4l2loopback kernel drivers to create a gstreamer device for apps that don’t support libcamera. There were only old versions available in copr but no surface kernel headers available so I couldn’t build the kernel modules. I switched to ubuntu 22.10 and got similar hardware support but more available packages. I’m still trying to figure out how to get the IR sensors to work so I can use howdy for login/sudo. https://github.com/boltgolt/howdy

First, you'll need to install Howdy.

I've tried using Howdy, but that doesn't seem to work. It's probably because of this issue

Just like with digicams, it is not just about the sensor, but also the image processing itself. Should we omit the IR sensor to replace it with a better firmware-based noise-reduction system? But what about "Howdy" / "Hello" users, if we go this route?

or ISW

I use isw to control GPU and CPU fans

On Linux, there is isw. Using this tool, I can manually disable this fan by writing the value of 0 to the memory address which represents GPU fan level 1. There is also GPU fan level 0 which already contains the value 0 but this seems to be ignored (for CPU, level 0 plays a role on the other hand). Moreover, the address which is supposed to show the GPU temperature just displays 255 (which would imply meltdown). Maybe there is some confusion, because the device doesn't have a dedicated GPU (just Intel Iris Xe).

You need this. ISW

You must have enabled battery conservation mode in msi dragon center before switching to windows. In order to fix this you have to modify the ec. Use isw tool to alter the ec config and control the fan/battery level. If nothing works then switch back to windows and disable battery conservation then install linux.

disable thermald, relying on my fan profiles (https://github.com/YoyPa/isw for MSI laptops) and tweaking my tlp config. if that fails i will use the default config and try auto-cpufreq to limit my max clock speeds

Fast-forward about a week, and I'm trying to set up my fan curves on a refreshed Arch Linux install, when I notice something that doesn't quite look right. Dumping the EC with isw shows the EC firmware as 16P5EMS1 - in other words, the embedded controller firmware for a GP63 board, which shouldn't match any 9th-gen models. It's not like it's a leftover bit of cached data from the old board, either; it's what shows up in the UEFI menu, even after flashing a newer BIOS containing the 'proper' EC firmware. Given the apparent mismatch, it doesn't seem like the firmware listed on MSI's page for the GE75 would pass the pre-flash checks, and it'd be a dumb idea to try and force it.
