hdmi_automation_enable(9)

💅 hdmi_automation_enable(9) — like, the Kernel API Manual bestie ✨

okay so bestie, this one lives in the Kernel API Manual and it's literally called hdmi_automation_enable — and no, we're not gatekeeping, it's giving "flip the HDMI automation feature on or off" energy 🎀

---

🌸 NAME 🌸

hdmi_automation_enable — Enable/Disable HDMI automation feature 🦋

---

✨ SYNOPSIS ✨

ssize_t hdmi_automation_enable (struct file *f , const char __user *buf
, size_t size , loff_t *pos );

that's the whole signature, no cap — copy it exactly, she's iconic 💅

---

🎀 ARGUMENTS 🎀

• f — file structure. yeah. the file structure. it's there, it's doing file structure things 🫶
• buf — userspace buffer. this is the main character fr fr: set it to '1' to enable the automation feature, or '0' to disable it. one digit, big power ⭐
• size — size of buffer from userspace. lowkey just telling you how much buffer you're working with 🙈
• pos — unused. literally not used. she's just vibing in the parameter list, we love a decorative queen 👑

---

💖 DESCRIPTION 💖

Return size on success, error code on failure. that's it, that's the whole vibe check — happy path gives you back size, sad path gives you an error code 😭

ngl bestie, keep those paths and option names exactly as written — copying code is a slay, changing code is a crime 💀
