💅 intel_displ...get_dc_state(9) — Kernel API Manual 🎀

okay bestie, so this one lives in the Kernel API Manual, and the page header is literally intel_displ...get_dc_state(9) (yes the man page gods truncated it, it's giving "we ran out of column width" 😭 — the real deal is spelled out below). Buckle up 🦋

---

✨ NAME ✨

intel_display_power_set_target_dc_state — set target dc state. periodt. 👑

---

🌸 SYNOPSIS 🌸

void intel_display_power_set_target_dc_state (struct intel_display
*display , u32 state );

no cap, that's the whole signature 💅

---

🦋 ARGUMENTS 🦋

• display — the display device. your main character, fr fr 👑
• state — the state which needs to be set as target_dc_state. this is the value you're serving the power well 💖

---

💜 DESCRIPTION 💜

so this function sets the "DC off" power well's target_dc_state, based upon this target_dc_stste (yes, the original manpage really does spell it target_dc_stste — iconique typo, we keep it 🫶). and based on that, the "DC off" power well will enable the desired DC state. literally that's the whole vibe check ✨
