🎀 NAME 🎀

🌸 SYNOPSIS 🌸

so if you wanna bake this driver into the kernel, you drop this line into your kernel configuration file:

device acpi_sony

OR, if you'd rather be a chill module girlie and load it at boot time, put this in loader.conf(5):

acpi_sony_load="YES"

both are valid. both slay. pick your fighter 🦋

✨ DESCRIPTION ✨

the acpi_sony driver is here to give you support for the notebook controller in Sony laptops. that's its whole thing. that's its moment. main character energy, no notes 💜

heads up though — not all features will work on all laptop models. lowkey tragic but that's just how it is, the hardware varies and we can't fix that with vibes 😭
