STRUCT DMUB_RB_CMD_DIG1_TRANSMITTER_CONTROL(9)

💅 struct dmub_rb_cmd_dig1_transmitter_control(9)

okay so this one's from the Kernel API Manual bestie, and it's a struct page — short and sweet, no cap. It's giving "tiny little struct that carries a big job" and I'm obsessed 🎀

---

✨ NAME ✨

struct dmub_rb_cmd_dig1_transmitter_control — the Transmitter control command. literally what it says on the tin 💖

---

🌸 SYNOPSIS 🌸

struct dmub_rb_cmd_dig1_transmitter_control {
    struct dmub_cmd_header header;
    union dmub_cmd_dig1_transmitter_control_data transmitter_control;
 };

the way that it's just a header plus one big ol' union… she's compact, she's iconic, she's exactly two members 🫶 copy it verbatim bestie, don't you dare touch it 😭

---

🦋 Members 🦋

ok so the members section on this page is empty in the original — like, there's a heading with nothing under it 🙈 which is lowkey funny but also very "trust me bro, the struct definition above is all you're getting." neither of the two members is described here, so I'm not gonna invent lore that isn't real ✨ the struct itself is above, header and transmitter_control, and that's fr fr it 💀

(and yes, enum dmub_cursor_offload_comand_type(9) really is spelled like that in the source — not my typo, I would never 😌)

💡 also worth knowing: the kernel file this lives in is ./drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h — that's the whole neighborhood right there 🏡

and that's the page!! short king behavior honestly 👑 if you made it through all 72 SEE ALSO entries you deserve a little treat 🍓🧚💜

— mwah, this has been the Kernel API Manual, source path shown as ./drivers/gpu/drm/amd/display/..., dated October 2026 ✨ see you in the next one bestie!! 💅💖
