bonw15: G-Sync Not Enabled?

[ilikenwf]

• Model: bonw15
• BIOS version: current
• EC version: current
• OS: Archlinux
• Kernel: cachy

G-Sync does not appear to be setup anywhere in the gpio.c file as it is with the serw15 and others, but the laptop itself should have the capability - the BOE 144hz LCD supports it, the 40XX gpus support it...it's just something somewhere in firmware does not support it.

I've tried both in hybrid and in dedicated graphics mode without luck in both Linux and Windows...it makes no sense.

I'm at a loss, I can't figure it out...

Schenker is legally sharing the schematics for this particular model, under a different name, and there is information in that document relevant (see bottom of page) - I can't find any GPIO directly labeled for g-sync detection but there's an nvidia page that discusses somethign to do with vendor bits for that?

Steps to reproduce

Try to use G-sync in Linux and Windows, in hybrid and dgpu only mode. It will fail.

Is this something to do with some GPIO needing pulled, or is it something to do with adding VRR support or configuring the dGPU vendor bit?

The clevo/sager x370 models on default firmware with the 144hz LCD support it so really shouldn't it work for us too?
