STRUCT VDEC_HEVC_SLICE_INFO(9)

✨ struct vdec_hevc_slice_info — decode information ✨

okay so bestie, welcome to the struct vdec_hevc_slice_info(9) page 💖 — yes that's the Kernel API Manual, and yes it's a little one, but it's important so let's give it the attention it deserves 🎀

This is the struct that carries the decode information, and honestly it's giving backstage-pass vibes — it's the little bundle of info that the HEVC decoder needs to actually do its thing 🦋

---

🌸 SYNOPSIS 🌸

struct vdec_hevc_slice_info {
    u64 wdma_end_addr_offset;
    u64 timeout;
    u64 vdec_fb_va;
    u32 crc[8];
};

look at that tidy little struct, no cap 🫶 four members, all business 💅

✨ Members ✨

💫 wdma_end_addr_offset

a u64 holding the wdma end address offset — literally the end address offset for wdma, that's the whole vibe 🔥

⏰ timeout

the decode timeout, and it's a strict binary situation ngl:

• 1 → timeout
• 0 → no timeout

no in-between, iykyk 🌈

🧚 vdec_fb_va

a u64 that's the VDEC frame buffer struct virtual address — the virtual address of the frame buffer struct, main character energy 👑

🍓 crc

u32 crc[8] — an array of 8, and it's used to check whether hardware's status is right 💀 like a little vibe check for the hardware, fr fr. If the hardware's status is acting sus, this is how you find out 🙈

ngl this one's short and sweet — every member is a u64 or a u32 array, no tricks, no undefined behaviour drama, just decode info doing its job 💜
