icl_set_active_port_dpll(9)

💅 icl_set_active_port_dpll — like, the whole vibe of this page 💅

okay so real quick, we're in the Kernel API Manual bestie, and this page is about icl_set_active_port_dpll(9) — the little function that goes "this one. this is the port DPLL we're using for this CRTC." that's it. that's the whole personality. 🎀

---

✨ NAME ✨

icl_set_active_port_dpll — pick the active port DPLL for a given CRTC 🦋

---

🌸 SYNOPSIS 🌸

void icl_set_active_port_dpll (struct intel_crtc_state *crtc_state ,
enum icl_port_dpll_id port_dpll_id );

she takes two things and returns literally nothing (void, no thoughts head empty) 💜

---

🧚 ARGUMENTS 🧚

• crtc_state — the state for the CRTC that we're selecting the DPLL for. this is the who of the operation 🫶
• port_dpll_id — the active port_dpll_id you want to select. this is the which one 💅

---

👑 DESCRIPTION 👑

so what she does is: she takes the given port_dpll_id instance and selects it out of the DPLLs that are reserved for the CRTC. like she's scrolling through the group chat and pointing at exactly one member. selected. iconic. periodt. ⭐

no cap, that's the whole description — she selects the given port_dpll_id instance from the DPLLs reserved for the CRTC. 🍓
