✨ ata_sff_wait_after_reset(9) ✨

okay so bestie, this is ata_sff_wait_after_reset(9) from the Kernel API Manual, and it's literally the “wait for devices to become ready after reset” girlie. no cap, she's a real one. 🫶

---

💖 NAME 💖

ata_sff_wait_after_reset — wait for devices to become ready after reset.

---

🌸 SYNOPSIS 🌸

int ata_sff_wait_after_reset (struct ata_link *link , unsigned int
       devmask , unsigned long deadline );

---

🎀 ARGUMENTS 🎀

• link — SFF link which is just reset.
• devmask — mask of present devices.
• deadline — deadline jiffies for the operation.

---

🦋 DESCRIPTION 🦋

okay so what's the vibe? It waits for devices attached to the SFF link to become ready after reset. It contains a preceding 150ms wait to avoid accessing the TF status register too early, which is highkey important. ⏳✨

LOCKING: Kernel thread context (may sleep). so yes, she may sleep, and that's iconic.

---

🔥 RETURN 🔥

• 0 on success.
• -ENODEV if some or all of the devices in devmask don't seem to exist.
• -errno on other errors.
