intel_dp_max_link_data_rate(9)

💅 intel_dp_max_link_data_rate(9)

okay bestie, welcome to the Kernel API Manual — yes, the whole manual, and yes, we're reading it together 🫶 this one's a lil function that does exactly one thing and does it iconically.

---

✨ NAME ✨

intel_dp_max_link_data_rate — calculates the maximum rate for the given link params. that's it, that's the whole vibe 💫

---

🌸 SYNOPSIS 🌸

int intel_dp_max_link_data_rate (struct intel_dp *intel_dp , int max_dprx_rate , int max_dprx_lanes );

three args in, one int out. lowkey elegant, ngl 💅

---

🎀 ARGUMENTS 🎀

• intel_dp — the Intel DP object itself, our main character 👑
• max_dprx_rate — the maximum data rate of the DPRX. that's the ceiling, bestie 🔥
• max_dprx_lanes — the maximum lane count of the DPRX. how many lanes we're working with 🛣️

---

🦋 DESCRIPTION 🦋

so the way this works: it calculates the maximum data rate for the link parameters you handed it, and it does take into account any BW limitations that come from a DP tunnel attached to intel_dp. like, it's not just vibes — there's a tunnel and it's limiting things 😭

and it returns the maximum data rate in kBps units. kBps, not kB/s, not MBps, kBps. write it down 📝✨

and that's the page! 🎉 this cutie came out of ./drivers/gpu/drm/i915/display in October 2026, and it's filed under the intel_dp_max_link_data_rate(9) girly herself. slay, periodt, go read some DRM source 💖🌸
