ahci_platform_init_host(9)

✨ ahci_platform_init_host ✨

okay so this page is from the Kernel API Manual (the ahci_platform_init_host(9) entry, to be exact) and it's literally about bringing up an ahci-platform host 💅 like, the whole glow-up from "just a platform device" to "fully registered host" — no cap.

🌸 NAME 🌸

ahci_platform_init_host — bring up an ahci-platform host 🎀

---

🦋 SYNOPSIS 🦋

int ahci_platform_init_host (struct platform_device *pdev , struct
       ahci_host_priv *hpriv , const struct ata_port_info *pi_template , const
       struct scsi_host_template *sht );

---

💖 ARGUMENTS 💖

• pdev — the platform device pointer for the host, like, the main character of this whole situation 👑
• hpriv — the ahci-host private data for the host, aka its personal lore 🫶
• pi_template — the template for the ata_port_info to use, slay ✨
• sht — the scsi_host_template to use when registering, iconic fr fr

---

🌈 DESCRIPTION 🌈

so basically this function does all the usual steps needed to bring up an ahci-platform host — the whole routine, none skipped, periodt 💅

⚠️ big heads-up bestie: any necessary resources (like clks, phys, etc.) must be initialized / enabled before calling this. Like, that's on you, not on the function 😭 it's giving "prep work is your job" energy.

---

⭐ RETURN ⭐

0 on success, otherwise a negative error code 🙈 — so zero is the slay outcome, negative means something went sideways 💀
