STRUCT DMCUB_TRACE_BUF_ENTRY(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual page for struct dmcub_trace_buf_entry — the Firmware trace entry ✨ and yes the page header up top is literally struct dmcub...ce_buf_entry(9) because somebody's terminal ate the middle of the name 😭 tragic, but we move 💅

it's a struct, it's about firmware tracing, and that's the whole vibe check. iconic of it honestly 🎀

---

✨ SYNOPSIS ✨

here's the whole shape of it, no cap, copied exactly:

struct dmcub_trace_buf_entry {
    dmub_trace_code_t trace_code;
    uint32_t tick_count;
    uint32_t param0;
    uint32_t param1;
 };

look at her. four little fields. a trace_code of type dmub_trace_code_t 👑, then tick_count, param0 and param1, all uint32_t 🧚 so clean, so demure.

---

🌸 MEMBERS 🌸

okay so this is the part where I'd hype up each member one by one and give you the whole breakdown…

…except the Members section on this page is literally blank bestie 💀 like, nothing. empty. the void. no descriptions listed, no per-field notes, nada 🙈

so the only tea we have on the members is the synopsis above: trace_code, tick_count, param0, param1. that's it, that's the whole buffet 🍓 if you wanted field-by-field lore, this page isn't serving it. iykyk 🫶

like. seventy-something structs and enums and unions all hanging out in one header file 🦋 that's a lot of friends, and every single one of them is a (9) kernel API page, periodt 💅

real talk for a sec: that list is long enough that if you're grepping for one specific name, just ctrl-F the header file. your wrists will thank you 🙏

and that's the page, bestie 🫶 this one came from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 ⭐ go read the other seventy pages in the group chat, they're all waiting 💖🎀
