STRUCT DMUB_RB_CMD_IDLE_OPT_SET_DC_POWER_STATE(9)

🎀 struct dmub_rb_cmd_idle_opt_set_dc_power_state(9) 🎀

okay so this is from the Kernel API Manual and bestie, it's a struct page — short, sweet, and honestly kind of an icon. Let's get into it 💅

---

✨ NAME ✨

struct dmub_rb_cmd_idle_opt_set_dc_power_state — literally just the data that gets passed to FW inside a DMUB_CMD__IDLE_OPT_SET_DC_POWER_STATE command. That's it. That's the whole vibe ✨

---

🌸 SYNOPSIS 🌸

struct dmub_rb_cmd_idle_opt_set_dc_power_state {
    struct dmub_cmd_header header;
    struct dmub_idle_opt_set_dc_power_state_data data;
 };

---

💖 Members 💖

Two members, no notes, both serving exactly what they need to serve 🫶

• header — a struct dmub_cmd_header. It's the command header, sitting up top like the main character it is 👑
• data — a struct dmub_idle_opt_set_dc_power_state_data. This is the actual payload of the command, living its best life right underneath 💜

bestie note: every one of those is literally part of the same dmub_cmd.h family — iykyk 🌈

okay that's the whole page, mwah 💋 this cutie lives in the kernel file ./drivers/gpu/drm/amd/display/..., it's dated October 2026, and it goes by struct dmub_rb_cmd_idle_opt_set_dc_power_state(9). slay, go read the others, periodt 🧚‍♀️⭐
