🌸 NAME 🌸

drm_show_fdinfo — helper for drm file fops. that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

void drm_show_fdinfo (struct seq_file *m , struct file *f );

---

💖 ARGUMENTS 💖

• m — the output stream, aka where all the text goes 🫶
• f — the device file instance, the actual file we're snooping on 🔥

---

👑 DESCRIPTION 👑

so this function is the helper you use to implement fdinfo — you know, the thing that lets userspace come thru and query usage stats and all that good stuff about a process that's using the GPU 👀✨

also go check out drm_driver.show_fdinfo while you're at it, iykyk.

for the whole text output format description situation, please see Documentation/gpu/drm-usage-stats.rst — the docs ate, no cap 💜
