STRUCT VDEC_VP9_SLICE_VSI(9)

💅 struct vdec_vp9_slice_vsi(9) — the kernel API manual, bestie edition 🎀

okay so bestie, you're reading the manual page for struct vdec_vp9_slice_vsi(9), and honestly? she's a whole vibe. this is the struct that handles exchange decoding information between Main CPU and MicroP — like the group chat between your big CPU and the tiny MicroP, and you are the one keeping receipts ✨

🦋 NAME

struct vdec_vp9_slice_vsi — exchange decoding information between Main CPU and MicroP 💌

like, the Main CPU and the MicroP are literally passing notes in class, and this struct is the note. no cap.

🌸 SYNOPSIS

struct vdec_vp9_slice_vsi {
    struct vdec_vp9_slice_bs bs;
    struct vdec_vp9_slice_fb fb;
    struct vdec_vp9_slice_fb ref[3];
    struct vdec_vp9_slice_mem mv[2];
    struct vdec_vp9_slice_mem seg[2];
    struct vdec_vp9_slice_mem tile;
    struct vdec_vp9_slice_mem prob;
    struct vdec_vp9_slice_mem counts;
    struct vdec_vp9_slice_mem ube;
    struct vdec_vp9_slice_mem trans;
    struct vdec_vp9_slice_mem err_map;
    struct vdec_vp9_slice_mem row_info;
    struct vdec_vp9_slice_frame frame;
    struct vdec_vp9_slice_state state;
 };

look at her. so many fields. main character energy fr fr 👑

🧚 Members

she's got a lot going on and every single member matters, so let's go down the list one by one, no skips 🫶

• bs — input buffer ✨ (the stuff going in, iykyk)
• fb — output buffer 💖 (the stuff coming out)
• ref — 3 reference buffers 🎀 (yes, three. count them.)
• mv — mv working buffer 🌸
• seg — segmentation working buffer 🦋
• tile — tile buffer ⭐
• prob — prob table buffer, used to set/update prob table 💅
• counts — counts table buffer, used to update prob table 🌈
• ube — general buffer 👑
• trans — trans buffer position in general buffer 📍
• err_map — error buffer 💀
• row_info — row info buffer 🍓
• frame — decoding syntax 🔥
• state — decoding state 💜

not me listing every single one because skipping any of them would be a crime 🙈 — this is the whole struct, nothing left out, periodt.

🌟 SEE ALSO

okay so if you want the full lore, the main character lives in the Kernel file here:

./drivers/media/platform/mediatek/vcodec/decoder/vdec/vdec_vp9_req_lat_if.c

and she travels with her friends, who each have their own manual pages ✨:

• struct vdec_vp9_slice_counts_map(9)
• struct vdec_vp9_slice_pfc(9)
• struct vdec_vp9_slice_instance(9)

go read them too, they're iconic, i don't make the rules 💅

and that's the whole page bestie 🎀 — this lil manual came from the source path ./drivers/media/platform/media... and it's dated October 2026, still titled struct vdec_vp9_slice_vsi(9) like the icon she is. mwah, go forth and decode 🦋💖✨
