STRUCT DMUB_RB_CMD_CAB_FOR_SS(9)

🌸 struct dmub_rb_cmd_cab_for_ss(9) 🌸

okay bestie, welcome to the Kernel API Manual — yes the Kernel API Manual 💅 this one's a lil niche but we're gonna slay it together, no cap.

---

💖 NAME 💖

struct dmub_rb_cmd_cab_for_ss — literally just CAB command data. that's the whole vibe. that's the assignment. ✨

---

🦋 SYNOPSIS 🦋

here's the shape of her, copy it exactly or the compiler will simply end you:

struct dmub_rb_cmd_cab_for_ss {
    struct dmub_cmd_header header;
    uint8_t cab_alloc_ways;
    uint8_t debug_bits;
 };

like look at her. three fields. header is a whole struct dmub_cmd_header (she has lore, see below 👀), and then cab_alloc_ways and debug_bits are both just uint8_t — tiny lil bytes, main character energy in the smallest possible package 🎀

---

🌈 Members 🌈

bestie. i have to be so fr fr with you right now. the manual page has a Members section… and it is empty. nothing. a beautiful void. 💀

so the members are listed in the SYNOPSIS up there — header, cab_alloc_ways, debug_bits — but this page does not hand you per-member descriptions. that's just how it is. i don't make the rules, i only serve them with glitter on top 🫶

seventy-two icons. seventy-two. the way she keeps her circle close 😭🔥 go read struct dmub_cmd_header(9) first tho, iykyk 👑

lowkey important reminder bestie: this page gave us the struct layout and the friend list, and that's it — no member-by-member deets, no exit statuses, no env vars. don't go inventing lore that isn't in the source, that's not the move 🙈

---

aaaaand that's the whole page, short and sweet like a lil strawberry 🍓 mwah.

so like, stay cute, stay compiled, and remember — this one came out of ./drivers/gpu/drm/amd/display/... and it's dated October 2026, so yes, she's from the future and she's thriving ⭐🧚‍♀️ 💜
