STRUCT VDEC_AV1_SLICE_PFC(9)

💅 struct vdec_av1_slice_pfc(9) — straight from the Kernel API Manual 🎀

okay so bestie, picture this: you're deep in the Kernel API Manual and you hit this struct. don't panic. it's lowkey the cutest little container ever and i'm gonna walk you through it 🫶

---

✨ NAME ✨

struct vdec_av1_slice_pfc — it's the per-frame context that contains a local vsi, and the whole point is that you pass it from lat to core. that's the job. that's the vibe. 💅

---

🌸 SYNOPSIS 🌸

struct vdec_av1_slice_pfc {
    struct vdec_av1_slice_vsi vsi;
    u64 ref_idx[V4L2_AV1_REFS_PER_FRAME];
    int seq;
};

look at her. three members. no notes. ✨

🦋 Members 🦋

• vsi — your local vsi. and listen, the rule is copy to/from remote vsi before/after decoding. before? copy. after? copy. it's giving responsible main character energy, ngl 😭
• ref_idx[V4L2_AV1_REFS_PER_FRAME] — the reference buffer timestamp. she holds the receipts (timestamps) for the reference buffers, one per V4L2_AV1_REFS_PER_FRAME slot 💖
• seq — the picture sequence. your order-in-line number. iconic for knowing who's first 🎀

and that's the page, bestie!! 💜 this little beauty ships from the source path ./drivers/media/platform/media... and she's dated October 2026 — so yes, she's from the future, and yes, she's still serving struct vdec_av1_slice_pfc(9) realness. periodt. 😌💅🌸
