STRUCT OMAP3ISP_PREV_CFA(9)

💅 struct omap3isp_prev_cfa(9) — like, the CFA Interpolation struct, bestie

okay so this is a page from the Kernel API Manual, and it's all about struct omap3isp_prev_cfa — which is literally the CFA Interpolation config for the OMAP3 ISP preview engine. no cap, that's the whole vibe. it lives in the kernel's UAPI headers so your userspace can talk to the preview block. let's get into it ✨

🌸 NAME 🌸

struct omap3isp_prev_cfa — CFA Interpolation 🎀

like, the struct that carries your Color Filter Array interpolation settings. iconic behavior honestly.

---

✨ SYNOPSIS ✨

struct omap3isp_prev_cfa {
    enum omap3isp_cfa_fmt format;
    __u8 gradthrs_vert;
    __u8 gradthrs_horz;
    __u32 table[4][OMAP3ISP_PREV_CFA_BLK_SIZE];
};

look at her. four fields, all business. 🫶

🦋 Members 🦋

okay so here's the breakdown of every single field, and yes we're doing all of them:

• format — the CFA Format Enum value that the preview engine supports. it's an enum omap3isp_cfa_fmt, so it's giving "pick your filter array layout" energy. 🌈
• gradthrs_vert — the CFA Gradient Threshold, Vertical one. a __u8, so tiny but mighty. 💜
• gradthrs_horz — the CFA Gradient Threshold, Horizontal one. also a __u8. she's the counterpart, we stan a matched set. 🍓
• table — pointer to the CFA table. it's declared as __u32 table[4][OMAP3ISP_PREV_CFA_BLK_SIZE] — four rows of blocks, all the coefficients live here. 👑

ngl the doc just says "Pointer to the CFA table" for table — but the actual type in the synopsis is that 2D __u32 array above, so keep that in mind. 💅

okay bye bestie, go interpolate some colors 💅✨
