intel_th_alloc(9)

🎀 intel_th_alloc(9) 🎀

okay bestie, welcome to the Kernel API Manual — today's main character is intel_th_alloc(9), and honestly? she's giving "let me build you a whole device from scratch" energy 💅

---

✨ NAME ✨

intel_th_alloc — allocate a new Intel TH device and its subdevices 🫶 (yes, all of them, we're not doing half a job here)

---

🌸 SYNOPSIS 🌸

struct intel_th * intel_th_alloc (struct device *dev , const struct
       intel_th_drvdata *drvdata , struct resource *devres , unsigned int
       ndevres );

look at that signature. four args. no cap, she's a lot but she's worth it 💖

---

🦋 ARGUMENTS 🦋

• dev — the parent device 👑 like, the device this whole thing belongs to
• drvdata — data private to the driver 🙈 it's hers, don't touch
• devres — resources indexed by th_mmio_idx ⭐ that index is doing the heavy lifting here, iykyk
• ndevres — number of entries in the devres resources 🔢 literally just how many are in there

lowkey important: devres and ndevres are a team. ndevres is the count, devres is the array. don't @ me.
