STRUCT HANTRO_POSTPROC_OPS(9)

💅 struct hantro_postproc_ops(9) — from the Kernel API Manual, bestie 🎀

okay so this is a whole page from the Kernel API Manual (yes, that manual) and it's literally just about one little struct: struct hantro_postproc_ops. it's the operations table for the post-processor. that's the whole vibe. let's get into it ✨

---

✨ NAME ✨

struct hantro_postproc_ops — post-processor operations 🦋

like, the ops. for the post-processor. she's a function-pointer struct and she's serving.

---

🌸 SYNOPSIS 🌸

struct hantro_postproc_ops {
    void (*enable)(struct hantro_ctx *ctx);
    void (*disable)(struct hantro_ctx *ctx);
    int (*enum_framesizes)(struct hantro_ctx *ctx, struct
v4l2_frmsizeenum *fsize);
 };

three pointers. that's her whole personality. no cap. 💅

👑 Members 👑

• enable — literally turns the post-processor block ON. Optional. so if a driver doesn't set it, that's fine, it's not mandatory, we're not judging. 🫶
• disable — the opposite queen: turns the post-processor block OFF. also Optional. icon behaviour.
• enum_framesizes — enumerates the possible scaled output formats ✨ Returns zero if everything's OK, and a negative value in error cases (so, 0 = slay, < 0 = 😭). also Optional, because of course she is. 💖

ngl the theme here is that every single member is marked Optional, so a driver can pick and choose which ones it actually implements. no pressure, bestie. 🎀
