STRUCT DMUB_RB_CMD_HPD_SENSE_NOTIFY(9)

💅 struct dmub_rb_cmd_hpd_sense_notify(9) 💅

okay so you're in the Kernel API Manual bestie, and today's main character is struct dmub_rb_cmd_hpd_sense_notify — the DMUB_OUT_CMD__HPD_SENSE_NOTIFY command. that's it, that's the whole vibe 🎀

---

✨ NAME ✨

struct dmub_rb_cmd_hpd_sense_notify — literally the DMUB_OUT_CMD__HPD_SENSE_NOTIFY command. no cap, that's what it is 💖

---

🌸 SYNOPSIS 🌸

here's the shape of it, copy it exactly please, don't freestyle:

struct dmub_rb_cmd_hpd_sense_notify {
    struct dmub_cmd_header header;
    struct dmub_rb_cmd_hpd_sense_notify_data data;
};

like… header first, then data. in that order. that's the whole struct, she's lowkey simple and I respect it 🫶

---

🦋 Members 🦋

so the original page has this section and… it's empty. like, nothing listed. zero members spelled out here even though the synopsis clearly shows header and data. so yeah — Members section exists, but there's nothing in it to read. iconic behavior honestly 💀

lowkey reminder: don't invent members, don't rename fields, don't get cute with the struct — the synopsis is the synopsis and the SEE ALSO list is sacred. iykyk 💜

and that's the page bestie!! source/version lives at ./drivers/gpu/drm/amd/display/... and she's dated October 2026 — mwah, historic. slay, go read the header file 🧚‍♀️⭐
