STRUCT RKISP1_CIF_ISP_AF_STAT(9)

🌸 struct rkisp1_cif_isp_af_stat — from the Kernel API Manual, bestie 🌸

okay so picture this: you're deep in the kernel docs, the Kernel API Manual is open, and you land on struct rkisp1_cif_isp_af_stat(9). don't panic. it's actually so chill. this is the lil struct that holds the auto focus stats, and i'm gonna walk you through it like we're texting at 2am 💅

---

✨ NAME ✨

struct rkisp1_cif_isp_af_stat — the statistics auto focus data container. literally that's its whole job. it holds the numbers. it's giving "quiet kid who does all the group project" energy 🫶

---

🦋 SYNOPSIS 🦋

struct rkisp1_cif_isp_af_stat {
    struct rkisp1_cif_isp_af_meas_val
window[RKISP1_CIF_ISP_AFM_MAX_WINDOWS];
 };

bestie, yes, that line break in the middle is exactly how it's written. we don't fix it, we respect it. it's iconic in its own way 💀

so what you're seeing: a window array of struct rkisp1_cif_isp_af_meas_val, and it's sized by RKISP1_CIF_ISP_AFM_MAX_WINDOWS. that's the whole vibe. that's the entire struct. no cap, it's that simple ✨

---

🎀 Members 🎀

• window — the AF measured value of window x. that's it, that's the member. one array, doing its thing, holding the sharpness result for each window. main character energy, honestly 👑

---

💖 Description 💖

okay so the why: the module measures the sharpness in 3 windows of selectable size via register settings (ISP_AFM_*_A/B/C). yes — 3 windows. and yes, the size is selectable, and the whole thing is driven by register settings with that ISP_AFM_*_A/B/C pattern — keep those registers in mind, iykyk 🌈

so like, AF (auto focus) needs to know how sharp stuff is, right? that's this. sharpness go brrr, stats get collected per window, and it all lands in that window array you just met. obsessed fr 🧚

buckle up bestie, this list is long long. like, scroll-for-a-while long. but every single one is here, because we don't skip entries in this house 💜

and that's the whole page, bestie!! one struct, one member, 3 windows, sharpness measured via register settings, and a SEE ALSO list longer than my screen time report 😭

sign-off time 🎀 this one comes from the source path ./include/uapi/linux, dated October 2026, living in the Kernel API Manual. slay. periodt. go read rkisp1_cif_isp_af_meas_val(9) next, mwah 💖✨
