ahci_platfo...le_resources(9)

💖 ahci_platfo...le_resources(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, yes the title up top is literally truncated to ahci_platfo...le_resources(9), and no we are not going to be normal about it. this page is short, it's sweet, and it's giving "last one out, turn off the lights" energy ✨

🌸 NAME 🌸

ahci_platform_disable_resources — Disable platform resources 💅

like, that's it. that's the whole job. it disables stuff.

---

🦋 SYNOPSIS 🦋

void ahci_platform_disable_resources (struct ahci_host_priv *hpriv );

returns nothing (it's void, she doesn't do returns) and takes exactly one thing. slay.

---

🎀 ARGUMENTS 🎀

• hpriv — the host private area where config values get stored. it's the little locker she keeps her stuff in 🫶

---

⭐ DESCRIPTION ⭐

so this function disables all the ahci_platform managed resources, and — important — it does it in this exact order, no freestyling, the order is the whole vibe check:

1. Phys
2. Resets
3. Clocks (through ahci_platform_disable_clks)
4. Regulator

that's the lineup. four steps. phys first, regulator last, clocks get handled via their own little helper. iconic behaviour honestly 🙈
