i2c bus is not exposed to /dev

[valpackett]

On Linux, the GPU's i2c bus is exported as /dev/i2c-n, which allows for e.g. DDC/CI monitor control via ddcutil. On Windows, VRMTool and WattTool can talk to the voltage controller over i2c.

Looks like the linux_i2c here is not connected to iicbus(4)…

Want to implement it? :)

hm, actually, I'm not sure why the Linux-style devices aren't showing up
