radeon_driver_unload_kms(9)

💖 radeon_driver_unload_kms(9) — Kernel API Manual 💖

✨ NAME ✨

Okay so this is radeon_driver_unload_kms(9), and it’s the main unload function for KMS. That’s the whole vibe: unload, but make it kernel-coded. Lowkey iconic. 🫶

🎀 SYNOPSIS 🎀

void radeon_driver_unload_kms (struct drm_device *dev );

Bestie, look at that signature — it’s giving “I take one pointer and I’m out.” 💅

🌸 ARGUMENTS 🌸

• dev — the drm dev pointer. Yep, that’s it. One argument, no drama. Vibe check passed. ✨

🦋 DESCRIPTION 🦋

This is the main unload function for KMS (all asics). Literally the cleanup main character. Not me being obsessed with a cleanup function, but here we are — it’s highkey important. 🫶

The way that it calls radeon_modeset_fini to tear down the displays, and radeon_device_fini to tear down the rest of the device (CP, writeback, etc.). So displays first, then the rest of the device bits — slay. Periodt. 💅

Returns 0 on success. No cap, that’s what the page says, so write it down. ✅

bestie note: the synopsis says void and the description says it returns 0 on success — both facts are in the original, fr fr, so keep both in your notes. 💀
