STRUCT VDEC_AV1_SLICE_MEM(9)

💅 struct vdec_av1_slice_mem(9)

okay so this is a page from the Kernel API Manual, section 9 — yes, the kernel-doc girlies are at it again, and this time it's about a lil struct called vdec_av1_slice_mem. bestie, it's literally just "memory address and size". that's the whole vibe. two things. an address, and a size. iconic minimalism, honestly. 🎀

---

✨ NAME ✨

struct vdec_av1_slice_mem — memory address and size 🫶

like… that's it. that's the struct. she's small, she's purposeful, she knows exactly what she's about.

---

🌸 SYNOPSIS 🌸

struct vdec_av1_slice_mem {
    union {
      u64 buf;
      dma_addr_t dma_addr;
    };
    union {
      size_t size;
      dma_addr_t dma_addr_end;
      u64 padding;
    };
 };

not me staring at two anonymous unions like they're the main characters… because they ARE. 👑

💖 Members 💖

okay so let's go member by member, no skipping, we do not leave anyone out in this house:

• {unnamed_union} — anonymous. yes ma'am, she has no name. mysterious. elusive. we respect her privacy. 💅
• buf — dma_addr padding. (that's literally what the good book says, I'm just the messenger 🙈)
• dma_addr — buffer address. the actual where-is-it of it all. 📍
• {unnamed_union} — anonymous. again!! a second nameless queen. the plot thickens, lowkey. 😭
• size — buffer size. how much. the quantity. the amount. her whole thing. 🍓
• dma_addr_end — buffer end address. where the buffer stops being a buffer and starts being a memory you don't own. 💀
• padding — for padding. yeah. she's padding. she's here for alignment reasons and vibes. ⭐

ngl bestie, if you're here you're probably deep in MediaTek vcodec decoder land, and honestly? slay. drink some water. 💜

and that's the page!! she was documented in October 2026, lives under ./drivers/media/platform/media..., and honestly she ate. no crumbs. periodt. 💅✨🔥
