✨ ahci_platform_enable_regulators(9) ✨

Okay bestie, welcome to the Kernel API Manual 💖 — this page is literally all about ahci_platform_enable_regulators, and no cap, it's a little baddie of a function. Let's get into it 👑

🌸 NAME 🌸

ahci_platform_enable_regulators — turn on the regulators, periodt 💅

🦋 SYNOPSIS 🦋

int ahci_platform_enable_regulators (struct ahci_host_priv *hpriv );

🎀 ARGUMENTS 🎀

  • hpriv — the host private area, aka where you store your config values 🫶 it's giving "my little bag of settings" energy.

🧚 DESCRIPTION 🧚

So basically this function enables all the regulators it can find in the controller and in hpriv->target_pwrs, if there are any 💜.

And here's the part where it's highkey smart: if one of the regulators refuses to turn on 😭, it goes ahead and disables all the regulators it already enabled — in reverse order — and then returns an error. Iconic cleanup behaviour fr fr, it doesn't leave a mess behind ✨.

⭐ RETURN ⭐

0 on success, otherwise a negative error code 💀 (that's the little "nope" signal, bestie).

💡 Friendly reminder: this whole squad lives under ./drivers/ata — the whole friend group of regulator/clk/phys/reset helpers. Go say hi 🍓

Alright bestie, that's the whole page 🎀💖 it came from the ./drivers/ata directory, dated October 2026, and yeah — the header and footer both cheekily abbreviate the name as ahci_platfo...e_regulators(9), which is giving "my name is too long for the terminal, help" 😭 slay either way 👑✨
