lwmi_om_psy_ext_init(9)

💖 NAME 💖

okay so bestie, welcome to the lwmi_om_psy_ext_init(9) page from the Kernel API Manual — this is literally the hook that attaches a power supply extension to a device battery. 🎀

✨ SYNOPSIS ✨

void lwmi_om_psy_ext_init (struct lwmi_om_priv *priv );

🌸 ARGUMENTS 🌸

• priv — a pointer to the lwmi_om_priv drvdata. That's the data bundle this function gets handed, no cap. 🫶

💅 DESCRIPTION 💅

So here's the tea: lwmi_om_psy_ext_init first checks whether the ideapad_laptop driver is going to manage charge attributes. If it's not, then it hooks the battery up to our WMI methods — but only if those WMI methods are supported. That's the whole flow, and it ate. ✨
