ns87560_tf_read(9)

💅 ns87560_tf_read — like, the whole manual page, bestie 💅

okay so this is ns87560_tf_read(9) from the Kernel API Manual and honestly? it's a little guy with a big job. let's get into it ✨

---

🌸 NAME 🌸

ns87560_tf_read — reads the input device's ATA taskfile shadow registers. that's the whole vibe. that's what she does. 💖

---

🎀 SYNOPSIS 🎀

void ns87560_tf_read (struct ata_port *ap , struct ata_taskfile *tf );

literally two args, no drama, no return value (it's void, she gives nothing back and that's iconic of her). 🫶

---

🦋 ARGUMENTS 🦋

• ap — the port you're reading input from. your source, your origin story, your main character. 🌈
• tf — the ATA taskfile register set where the input gets stored. it's the lil container that catches everything. 🎀

---

⭐ DESCRIPTION ⭐

so what she does, fr fr: she reads the ATA taskfile registers for the currently-selected device and drops them straight into tf. that's the whole plot. no cap. 💅

and then — the plot twist — she does it as a workaround for the 87560 bugs. yes bestie, there are bugs, and this function is the fix-it fairy for them. 🧚✨

LOCKING: inherited from the caller. translation? the locking energy is not hers to manage — whoever called her already handled it. don't come for her about locks, she got them from you. 😭
