dcn10_hubp_pg_control(9)

✨ dcn10_hubp_pg_control(9) — like, the Kernel API Manual one 💅

okay so bestie, buckle up, because we're diving into dcn10_hubp_pg_control from the Kernel API Manual and it's literally the power gate controller for your HUBP 🎀 no cap.

---

🌸 NAME 🌸

dcn10_hubp_pg_control — HUBP power gate control 🔥 it's giving "let there be light" but for hardware blocks, fr fr.

---

🦋 SYNOPSIS 🦋

void dcn10_hubp_pg_control (struct dce_hwseq *hws , unsigned int
       hubp_inst , bool power_on );

that's the whole signature, bestie — she takes three things and returns void, meaning she doesn't hand anything back, she just does ✨ iconic behaviour honestly.

---

🎀 ARGUMENTS 🎀

• hws — a dce_hwseq reference 💖 your little handle to the hardware sequencing stuff. you know her, you love her.
• hubp_inst — the DPP instance reference 👑 which instance we're talking about, iykyk.
• power_on — true if we want to enable the power gate, false otherwise 🌈 literally just a bool doing bool things.

---

💜 DESCRIPTION 💜

Enable or disable the power gate in the specific HUBP instance 🫶 that's it, that's the vibe. you pick an instance, you pick on or off, and the gate does its thing. main character energy for a power gate, ngl.

💀 reminder bestie: power_on = false means the gate gets disabled, not that the hardware is off forever — don't get it twisted 🙈
