UNION DMUB_RB_OUT_CMD(9)

💅 union dmub_rb_out_cmd(9) 💅

Kernel API Manual — ok bestie, sit down, we're doing the kernel API manpage thing and honestly? this one is short and sweet. no cap. 🎀

---

🌸 NAME 🌸

union dmub_rb_out_cmd — Outbox command ✨

That's literally it, that's the whole name section. Short king. 👑

---

✨ SYNOPSIS ✨

Here's the shape of it, character for character, because we do not freestyle code in this house:

union dmub_rb_out_cmd {
    struct dmub_rb_cmd_common cmd_common;
    struct dmub_rb_cmd_dp_aux_reply dp_aux_reply;
    struct dmub_rb_cmd_dp_hpd_notify dp_hpd_notify;
    struct dmub_rb_cmd_dp_set_config_reply set_config_reply;
    struct dmub_rb_cmd_dpia_notification dpia_notification;
    struct dmub_rb_cmd_hpd_sense_notify hpd_sense_notify;
    struct dmub_rb_cmd_fused_io fused_io;
 };

It's a union, so it's giving one-member-at-a-time energy — pick your fighter, the space is shared. 🫶

🎀 Members 🎀

Let's do the roll call by type, since that's exactly what the synopsis handed us:

• cmd_common — a struct dmub_rb_cmd_common 💖
• dp_aux_reply — a struct dmub_rb_cmd_dp_aux_reply 🌸
• dp_hpd_notify — a struct dmub_rb_cmd_dp_hpd_notify 🦋
• set_config_reply — a struct dmub_rb_cmd_dp_set_config_reply ✨
• dpia_notification — a struct dmub_rb_cmd_dpia_notification 🔥
• hpd_sense_notify — a struct dmub_rb_cmd_hpd_sense_notify 🌈
• fused_io — a struct dmub_rb_cmd_fused_io 🍓

Ngl, the Members heading in the original ships with zero described entries under it — the whole member story lives up in the synopsis. So we're not out here inventing descriptions, okay? No cap, no extra lore. 🙈

Sign-off time 🫶 — this lil masterpiece lives at ./drivers/gpu/drm/amd/display/... (yes, that's the path, that's how the page shows it, we don't trim it), dated October 2026, and it signs itself union dmub_rb_out_cmd(9) on the way out. Icons only. Periodt. 🦋🎀💖
