💅 drm_dp_tunnel_destroy(9) 💅

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're fancy here ✨ — and today's main character is drm_dp_tunnel_destroy, which is literally the function that says "bye, tunnel, you're done."

🌸 NAME 🌸

drm_dp_tunnel_destroy — destroy the tunnel object, no cap 🫶

✨ SYNOPSIS ✨

int drm_dp_tunnel_destroy (struct drm_dp_tunnel *tunnel );

like, that's the whole signature, she's not complicated 💅

🎀 ARGUMENTS 🎀

  • tunnel — the tunnel object itself, the one we're about to send off into the void 🦋

💖 DESCRIPTION 💖

So what does she actually do? She removes the tunnel from the tunnel topology and then destroys it. Two steps, one function, iconic behavior honestly ✨.

And the return situation? It's giving:

  • 0 on success — slay, it worked 🎉
  • -ENODEV if the tunnel has already been destroyed — like, it's already gone, bestie, there's nothing left to destroy 😭💀
fr fr, if you get -ENODEV back, that's your sign the tunnel already got destroyed. Don't double-destroy and then act surprised 🙈

🦋 SEE ALSO 🦋

The kernel file that lives at ./drivers/gpu/drm/display/drm_dp_tunnel.c — that's where the vibes come from 🧚

And the whole tunnel friend group, in the order the manpage listed them (yes, I'm keeping all of them, I would never skip any of my girls 💜):

🌈 sign-off 🌈
