STRUCT VDEC_H264_SLICE_INFO_EXT(9)

💅 NAME 💅

struct vdec_h264_slice_info_ext — okay so this is the extended decode info, and bestie, it's literally the shared data between host and firmware 🫶 like they're passing notes in class, except the notes are decode info, no cap.

---

✨ SYNOPSIS ✨

struct vdec_h264_slice_info_ext {
    u64 wdma_end_addr_offset;
    u16 nal_info;
    u16 timeout;
    u32 reserved;
    u64 vdec_fb_va;
    u32 crc[8];
 };

Look at that struct, it's giving organized queen energy 👑 every field exactly where it belongs, not a single byte out of place, periodt.

🎀 Members 🎀

• wdma_end_addr_offset — the offset from the buffer start. That's it, that's the whole vibe. She's a distance from where the buffer begins 💫
• nal_info — the nal info of the current picture 🖼️ literally just telling you what this picture's working with.
• timeout — toggles whether a decode operation is a timeout ⏰ highkey important, lowkey tiny. She's a switch, she flips, she decides.
• reserved — reserved 🙈 don't touch her, she's just sitting there being reserved, main character energy of doing nothing at all.
• vdec_fb_va — the vdec frame buffer struct virtual address 📍 where the frame buffer struct lives, like a little address label but for structs.
• crc — displays the hardware status 🔥 she's the one showing you what the hardware's actually up to, an array of 8 doing the lord's work.

💀 quick vibe check: I'm not adding anything extra here, because everything above is literally everything the page says. If you want the deeper lore, go read those SEE ALSO structs, they're the source, fr fr.

And that's the whole page, bestie! 🍓 This one came from ./drivers/media/platform/media... and the date on it is October 2026 — so yeah, she's a little futuristic, a little mysterious, and fully iconic ✨💜 Thanks for reading, mwah! 🧚
