STRUCT DMUB_RB_CMD_MALL(9)

✨ struct dmub_rb_cmd_mall — MALL command data ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a lil struct page from the kernel docs, and honestly? it's giving "small but mighty." let's get into it 🫶

🌸 NAME 🌸

struct dmub_rb_cmd_mall — MALL command data. that's it, that's the whole vibe ✨

---

🎀 SYNOPSIS 🎀

struct dmub_rb_cmd_mall {
    struct dmub_cmd_header header;
    union dmub_addr cursor_copy_src;
    union dmub_addr cursor_copy_dst;
    uint32_t tmr_delay;
    uint32_t tmr_scale;
    uint16_t cursor_width;
    uint16_t cursor_pitch;
    uint16_t cursor_height;
    uint8_t cursor_bpp;
    uint8_t debug_bits;
    uint8_t reserved1;
    uint8_t reserved2;
 };

like, look at her. she's got a header first (as she should 👑), then a cursor_copy_src and cursor_copy_dst (both union dmub_addr, iconic), then the tmr_delay and tmr_scale as uint32_t, and then the cursor squad rolls in — cursor_width, cursor_pitch, cursor_height, all uint16_t 💖 — followed by cursor_bpp and debug_bits as uint8_t, and finally reserved1 and reserved2, also uint8_t, just chillin' at the end holding space 🙈

🦋 Members 🦋

no cap, this section is literally empty in the source. not a single member description. so like… the members are just up there in the synopsis and honestly? they're doing main character energy all on their own 💅
