acpi_device_uevent_modalias(9)

💖 NAME 💖

acpi_device_uevent_modalias — uevent modalias for ACPI-enumerated devices. Okay bestie, you're reading the page for acpi_device_uevent_modalias(9) from the Kernel API Manual, and it's lowkey iconic ✨

🎀 SYNOPSIS 🎀

The signature, exactly as it is, no edits bestie:

int acpi_device_uevent_modalias (const struct device *dev , struct
       kobj_uevent_env *env );

🦋 ARGUMENTS 🦋

• dev — this is the struct device you hand over so we can grab the ACPI device node 👑
• env — the environment variables of the kobject uevent 🫶

🌸 DESCRIPTION 🌸

This function is highkey here to create the uevent modalias field for ACPI-enumerated devices 💅

Because other buses do not support ACPI HIDs & CIDs, e.g. for a device with hid:IBM0001 and cid:ACPI0001, you get "acpi:IBM0001:ACPI0001" — and that's the exact string, no cap 🔥 Periodt.
