💅 drm_dp_tunnel_atomic_get_state(9) 💅

okay bestie so this is a page straight out of the Kernel API Manual, section 9, and the star of the show is literally called drm_dp_tunnel_atomic_get_state — lowkey a mouthful but she ate 💖

✨ NAME ✨

drm_dp_tunnel_atomic_get_state — get/allocate the new atomic state for a tunnel 🎀

🦋 SYNOPSIS 🦋

struct drm_dp_tunnel_state * drm_dp_tunnel_atomic_get_state (struct drm_atomic_commit *state , struct drm_dp_tunnel *tunnel );

like... look at her. iconic signature, no cap ✨

🌸 ARGUMENTS 🌸

  • state — the atomic state, obviously 💅
  • tunnel — the tunnel you're grabbing the state for 🫶

💜 DESCRIPTION 💜

So here's the vibe: this function gets the new atomic state for tunnel, and if that state hasn't been allocated yet, she duplicates it from the old tunnel state — like, she's not gonna leave you hanging with a NULL, she makes a copy from the previous one first. main character energy fr fr 👑

Then she returns the state, or an ERR_PTR error on failure. that's it. that's the whole thing. ERR_PTR on failure, so like... check it, bestie, don't just assume 😭

🎀 SEE ALSO 🎀
