STRUCT VDEC_AV1_SLICE_STATE(9)

💅 struct vdec_av1_slice_state(9) — bestie edition

okay so this is a page straight out of the Kernel API Manual, and we're talking about struct vdec_av1_slice_state — the decoding state. yes it's a struct, yes it's short, no we are not skipping a single field, let's go 🎀

---

✨ NAME ✨

struct vdec_av1_slice_state — decoding state. that's it, that's the whole vibe. it holds the state of a decode. iconic, honestly 🦋

---

🌸 SYNOPSIS 🌸

struct vdec_av1_slice_state {
    int err;
    u32 full;
    u32 timeout;
    u32 perf;
    u32 crc[16];
    u32 out_size;
 };

look at her. six fields. no notes. 💖

okay bestie, field by field, don't skip:

• err — err type for decode. yeah, it's the type of error the decode hit. the "what went wrong" field 😭
• full — transcoded buffer is full or not. classic yes/no situation, lowkey important before you shove more data in there.
• timeout — decode timeout or not. same energy, different drama. did the decode time out? this field knows 💀
• perf — performance enable. the toggle for whether perf stuff is turned on ✨
• crc — hw checksum. hardware checksum, and she's an array: crc[16], sixteen of them, no cap 🔥
• out_size — hw output size. how big the hardware output is, literally that simple 👑

heads up bestie: the source location on this one got cut off as ./drivers/media/platform/media... — that's genuinely all we got, so don't come for me about it 🙈

and that's the page!! 💜 sign-off time: this one came from ./drivers/media/platform/media..., dated October 2026, and the manual is the Kernel API Manual — go off, struct vdec_av1_slice_state(9), periodt 🧚‍♀️⭐
