dcn314_dpp_pg_control(9)

💅 dcn314_dpp_pg_control(9) — from the Kernel API Manual, bestie 🎀

okay so welcome to the glow-up of dcn314_dpp_pg_control(9), a real kernel API manual page, and yes we're gonna read it together, it's gonna be cute and it's gonna be thorough ✨

✨ NAME ✨

dcn314_dpp_pg_control — DPP power gate control, no cap 🦋

---

🌸 SYNOPSIS 🌸

void dcn314_dpp_pg_control (struct dce_hwseq *hws , unsigned int
dpp_inst , bool power_on );

like literally that's the whole signature, she's not complicated, she just has three arguments and a dream 🫶

---

💖 ARGUMENTS 💖

• hws — a dce_hwseq reference. it's giving "here's the hardware sequencing context, bestie" 👑
• dpp_inst — the DPP instance reference. which DPP are we talking about?? this one. this specific one 🎯
• power_on — true if we want to enable the power gate, false otherwise. binary queen, we stan 💅

---

🔥 DESCRIPTION 🔥

so what she does: enable or disable the power gate in the specific DPP instance. that's the whole vibe check ✅

and here's the plot twist — if power gating is disabled, she will force disable the cursor in the DPP instance. not a suggestion, not a maybe, she just does it. cursor? gone. bye. 😭

fr fr remember: turning the power gate off takes the cursor down with it in that DPP instance. no cursor, no problem (well, no cursor, actually 🙈)
