🌸 drm_debugfs_create_files(9) — the Kernel API Manual moment 💅

okay bestie, this one lives in the Kernel API Manual and it's literally called drm_debugfs_create_files(9). say it with me: drm_debugfs_create_files — iconic name, no notes. ✨

✨ NAME ✨

drm_debugfs_create_files — initialize a given set of debugfs files for a DRM minor 🎀

🦋 SYNOPSIS 🦋

void drm_debugfs_create_files (const struct drm_info_list *files , int count , struct dentry *root , struct drm_minor *minor );

like, that's the whole signature. void return, four args, no drama. 🌈

💜 ARGUMENTS 💜

  • files — the array of files you wanna create. yes, the whole array. the lineup. the roster. 🫶
  • count — the number of files you're giving it. you gotta tell it how many besties are in the car, fr fr.
  • root — the DRI debugfs dir entry. (and yes, the manpage really does say "DRI" right there — not me, that's the original vibe check 💀)
  • minor — the device minor number. the little number that says which device we're talking about. 🔥

🧚 DESCRIPTION 🧚

so what it does: it creates a given set of debugfs files, represented by an array of struct drm_info_list, in the given root directory. that's the whole errand. lowkey simple, highkey important. ✨

and the best part? these files get removed automatically on drm_debugfs_dev_fini. no cleanup era needed, it handles itself. main character energy honestly. 👑

⭐ SEE ALSO ⭐

🫶 quick vibe check: schema things get cleaned up for you on drm_debugfs_dev_fini, but that's the only auto-magic promised here. don't invent extra behaviour, bestie — this page doesn't. 💖

and that's the page!! brought to you by ./drivers/gpu/drm, dated October 2026 🌸 — mwah, stan the kernel docs, periodt. 💅🎀
