STRUCT VDEC_AV1_SLICE_SM(9)

💅 struct vdec_av1_slice_sm(9) ✨

okay so this is a page straight out of the Kernel API Manual, and today's main character is struct vdec_av1_slice_sm — the AV1 Skip Mode parameters struct. yes bestie, skip mode. it's literally the "we're not even gonna bother predicting this one, just copy the vibes" of video decoding 🎀

---

🦋 SYNOPSIS 🦋

like, here's the whole struct, exactly as it is, no notes:

struct vdec_av1_slice_sm {
    u8 skip_mode_allowed;
    u8 skip_mode_present;
    int skip_mode_frame[2];
 };

that's it. three fields. small struct, big energy 💖

---

🌸 Members 🌸

⭐ skip_mode_allowed

a u8 that says whether Skip Mode is allowed or not. that's the whole vibe check right there — yes or no, in or out 🫶

⭐ skip_mode_present

another u8, and it specifies whether the skip_mode will be present or not. allowed ≠ present, okay? they're different things and both are serving 💅

⭐ skip_mode_frame

an int array of size 2 — it specifies the frames to use for compound prediction. two frames, one array, iconic behavior ngl 👑

💀 real talk though: this struct is tiny and the file path in the original page got cut off at ./drivers/media/platform/media..., so if you're hunting the exact source, follow that first path in the list — that's the one with all the letters 🧚

🎀 the sign-off 🎀

this little icon of a page is dated October 2026 and hails from the file ./drivers/media/platform/media... (yes, truncated just like that, we don't gatekeep, we also don't finish our paths apparently 🙈), and it will forever introduce itself as struct vdec_av1_slice_sm(9). slay, bye 💜
