papr_rtas_se...le_interface(9)

👑 papr_rtas_setup_file_interface(9) — the Kernel API Manual glow-up ✨

Okay bestie, welcome to the Kernel API Manual page for papr_rtas_setup_file_interface (the header up top gets truncated to papr_rtas_se...le_interface(9) which is honestly giving haircut-gone-wrong, but we move 💇‍♀️). Sit down, hydrate, and let's get into it 🫶

---

🌸 NAME 🌸

papr_rtas_setup_file_interface — it finishes off the whole sequence for you, grabs the data, and exports it out to user space using fd-based handles. Then user space just goes and gets the data with a read() handle. That's it, that's the vibe 💅

---

✨ SYNOPSIS ✨

long papr_rtas_setup_file_interface (struct papr_rtas_sequence *seq ,
const struct file_operations *fops , char *name );

Look at her. Three args, one long return, zero notes. Iconic ✨

---

🎀 ARGUMENTS 🎀

• seq — the RTAS call specific functions that actually go get the data for you 🔥
• fops — the RTAS call specific file operations, like read. You know, the fun stuff 📖
• name — the RTAS call specific char device node 🧚

---

🦋 RETURN 🦋

An FD handle for consumption by user space 🍓 That's the whole snack, hand-delivered.
