STRUCT DMUB_CMD_ENABLE_DISP_POWER_GATING_DATA(9)

💅 struct dmub_cmd_enable_disp_power_gating_data(9) 💅

okay bestie so this one comes straight out of the Kernel API Manual and it's literally the struct that handles display power gating ✨ it's giving "small struct, big vibes" — one whole member, that's it, and honestly she ate 🎀

---

🌸 NAME 🌸

struct dmub_cmd_enable_disp_power_gating_data — Display power gating. that's the whole thing. short. iconic. periodt 💅

---

✨ SYNOPSIS ✨

the whole struct, verbatim, do not touch, do not edit, do not "improve" it, i'm watching 👀

struct dmub_cmd_enable_disp_power_gating_data {
    struct enable_disp_power_gating_parameters_v2_1 pwr;
 };

like look at her. one field. pwr. the struct enable_disp_power_gating_parameters_v2_1 is doing all the heavy lifting and she knows it 🫶

---

🦋 Members 🦋

so this is where it gets kinda funny — the manpage has a Members section and it's… empty. like crickets 💀 nothing listed under it at all, no field-by-field breakdown, nada. so there's genuinely nothing to tell you here beyond "the section exists and it's a void" 🙈 i'm not gonna invent members for you, no cap, that would be fake news.
