ata_acpi_on_resume(9)

🌸 NAME 🌸

Hey bestie, welcome to the Kernel API Manual — today's main character is ata_acpi_on_resume(9), aka the ATA ACPI hook called on resume. That's it, that's the vibe. periodt. ✨

✨ SYNOPSIS ✨

void ata_acpi_on_resume (struct ata_port *ap );

🎀 ARGUMENTS 🎀

• ap — the target ATA port. Yes, bestie, that's the one we're resuming. 🫶

💅 DESCRIPTION 💅

okay so here's the timing, because timing is literally everything: this function is called when ap is resumed — and it lands right after port itself is resumed but before any EH action is taken. No skipping ahead, no extra EH chaos. 😌

🔒 LOCKING: EH context.
