amdgpu_pll_...ared_dp_ppll(9)

💅 NAME 💅

amdgpu_pll_get_shared_dp_ppll — bestie, this one returns the PPLL that another crtc is using for DP 👑

---

✨ SYNOPSIS ✨

int amdgpu_pll_get_shared_dp_ppll (struct drm_crtc *crtc );

---

🎀 ARGUMENTS 🎀

• crtc — the drm crtc, aka the main character of this function call 🌸

---

🦋 DESCRIPTION 🦋

Okay so picture this: this function returns the PPLL (that's the Pixel PLL, keep up bestie 💅) that's being used by another crtc/encoder which is also vibing in DP mode. No cap.

And here's the iconic part — for DP, a single PPLL can be used for all the DP crtcs/encoders. One PPLL, serving the whole group chat. It's giving shared-resource queen energy 👑✨
