👑 sdw_intel_acpi_scan(9) 👑

okay so bestie, this is straight from the Kernel API Manual and it’s lowkey iconic: sdw_intel_acpi_scan is the SoundWire Intel init routine. It’s giving “let me check the firmware tables before we start the party” energy ✨

🌸 NAME 🌸

sdw_intel_acpi_scan — SoundWire Intel init routine

✨ SYNOPSIS ✨

int sdw_intel_acpi_scan (acpi_handle parent_handle , struct
       sdw_intel_acpi_info *info );

🎀 ARGUMENTS 🎀

• parent_handle — the ACPI parent handle. That’s it, that’s the whole vibe.
• info — description of what firmware/DSDT tables expose. no cap, this is where the firmware tea gets spilled 🍓

💅 DESCRIPTION 💅

This scans the namespace and queries firmware to figure out which links to enable. Like a little detective with a group chat full of DSDT tables 🕵️‍♀️ A follow-up use of sdw_intel_probe and sdw_intel_startup is required for creation of devices and bus startup. So yeah, this function is the opening act, not the whole concert 🫶
