💖 sdw_intel_probe(9) — Kernel API Manual 💖

okay so bestie, welcome to sdw_intel_probe(9) from the Kernel API Manual — literally the SoundWire Intel probe routine and she is lowkey the moment before everything pops off 🦋

---

✨ NAME ✨

sdw_intel_probe — the SoundWire Intel probe routine, no cap 💅

---

✨ SYNOPSIS ✨

struct sdw_intel_ctx * sdw_intel_probe (struct sdw_intel_res *res );

---

🌸 ARGUMENTS 🌸

• res — resource data. that's it, that's the vibe 🎀

---

🫶 DESCRIPTION 🫶

so what she does is: she registers an auxiliary device for each Master handled by the controller ✨ and then the SoundWire Master and Slave devices get created by the auxiliary device probe. it's giving delegation, main character energy 👑

All the info you need gets stored in the context, which means the res argument pointer can be freed after this step 🫶 so like, don't hold onto it, bestie, she's done with it.

Also important: this function gets called after sdw_intel_acpi_scan by SOF probe — that's the order of operations, no skipping 🙈
