STRUCT DMUB_RB_CMD_IDLE_OPT_DCN_NOTIFY_IDLE(9)

💅 struct dmub_rb_cmd_idle_opt_dcn_notify_idle(9) 💅

okay bestie so this is a Kernel API Manual page, and before your eyes glaze over — it's actually just a lil struct. one struct. that's the whole page. we love a low-effort icon ✨

---

🎀 NAME 🎀

struct dmub_rb_cmd_idle_opt_dcn_notify_idle — literally just the data that gets handed off to FW (firmware, bestie) inside a DMUB_CMD__IDLE_OPT_DCN_NOTIFY_IDLE command</p>. that's it. that's the job. 🫶

---

🌸 SYNOPSIS 🌸

the whole moment, in code:

struct dmub_rb_cmd_idle_opt_dcn_notify_idle {
    struct dmub_cmd_header header;
    struct dmub_dcn_notify_idle_cntl_data cntl_data;
 };

two members. no more, no less. header and cntl_data. we stay consistent. 💅

---

🦋 Members 🦋

okay so this section... is empty. genuinely. nothing in it. no cap, there's not a single member documented here — the fields you actually care about are the two chilling up there in the synopsis: header (a struct dmub_cmd_header) and cntl_data (a struct dmub_dcn_notify_idle_cntl_data). that's the whole tea. 🍓

🔥 SEE ALSO 🔥

this list is LONG and honestly it ate. all of these are cousins of this struct, living their lives in the same header. no skips, no cuts, we cite everybody 👑

and where does all this live? Kernel file ./drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h — that's the address, bestie, go visit 🧚

💀 real talk: this page is short because the struct is basically a lil envelope — a header and a cntl_data, nothing else. all the actual drama is in the structs it points at. go read struct dmub_dcn_notify_idle_cntl_data(9) if you want the lore.

---

and that's the whole page, bestie!! 🌈 source? it came from ./drivers/gpu/drm/amd/display/... and this lil beauty is dated October 2026. the header/footer said struct dmub..._notify_idle(9) (they truncated it for aesthetic reasons ig 💅) — anyway, slay, go notify some idle DCN, mwah 🫶💖✨
