UNION DMUB_CMD_DIG1_TRANSMITTER_CONTROL_DATA(9)

💅 union dmub_cmd_dig1_transmitter_control_data(9) — the manual, but make it make sense

okay so bestie, welcome to the Kernel API Manual ✨ this one's a kernel-API page, and it's about one (1) little union. yes, the whole page. she's short, she's mysterious, she's got a synopsis and a wildly long SEE ALSO. let's get into it 💖

---

🌸 NAME 🌸

union dmub_cmd_dig1_transmitter_control_data — Transmitter control data. that's it, that's the name, no notes 🎀

---

✨ SYNOPSIS ✨

here's the whole shape of her, literally copied so you don't have to squint:

union dmub_cmd_dig1_transmitter_control_data {
    struct dig_transmitter_control_parameters_v1_6 dig;
    struct dmub_dig_transmitter_control_data_v1_7 dig_v1_7;
 };

two fields, no cap. that's the entire body of this union and honestly? iconic minimalism 🦋

---

🧚 Members 🧚

so… the Members section on this page is genuinely empty. like, empty-empty 😭 not a single member gets its own description here.

what you do get is the two members right up there in the synopsis, and that's your lot:

• dig — typed struct dig_transmitter_control_parameters_v1_6 🍓
• dig_v1_7 — typed struct dmub_dig_transmitter_control_data_v1_7 💜

and that's everything the page says about them. no blurb, no extra detail. if you want the tea on what's inside those structs, that's what SEE ALSO is for 👇

🔥 SEE ALSO 🔥

buckle up bestie, this list is long. the source file lives here:

pro tip from me to you: that's 73 refs and one header file. you're not gon na read them all in one sitting and that is fine 💅
