drm_dp_tunnel_mgr_create(9)

💖 NAME 💖

okay bestie, welcome to the drm_dp_tunnel_mgr_create(9) page from the Kernel API Manual ✨ this one is literally about creating a DP tunnel manager, and the original summary is drm_dp_tunnel_mgr_create - Create a DP tunnel manager. concise, iconic, slay.

✨ SYNOPSIS ✨

here's the exact signature, no edits, no vibe-based rewrites:

       struct drm_dp_tunnel_mgr * drm_dp_tunnel_mgr_create (struct drm_device
       *dev , int max_group_count );

🎀 ARGUMENTS 🎀

• dev — the DRM device object. that's the device the manager is for, periodt.
• max_group_count — maximum number of tunnel groups. that's the cap, bestie.

🌸 DESCRIPTION 🌸

this function creates a DP tunnel manager for dev 💅

if it succeeds, it returns a pointer to the tunnel manager. if it fails, it returns an error pointer.

no cap: failure comes back as an error pointer, not a success-vibes pointer. keep that energy.
