STRUCT PISP_BE_CAC_EXTRA(9)

💅 struct pisp_be_cac_extra(9) — the Kernel API Manual, bestie edition

okay so welcome to the struct pisp_be_cac_extra(9) page, from the Kernel API Manual ✨ this one is short and sweet and honestly kind of iconic for it 💖

---

🌸 NAME 🌸

struct pisp_be_cac_extra — the PiSP Back End CAC extra config. that's it. that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

lowkey the entire struct is right here, no cap:

struct pisp_be_cac_extra {
    __u16 offset_x;
    __u16 offset_y;
 };

two fields. two little __u16s. she's minimalist, she's efficient, she ate 💅

---

🦋 Members 🦋

• offset_x — the horizontal offset into the CAC table of this tile 🫶
• offset_y — the horizontal offset into the CAC table of this tile 👑

not me noticing both of these say horizontal 😭 that is literally what the page says, word for word, so I'm passing it straight to you unchanged — I am simply the messenger, do not come for me 💀

💜 that's the page!! tiny struct, huge main character energy. mwah. 🍓

sign-off time: this came from the kernel source path ./include/uapi/linux/media/ras... (yes, it's truncated just like that on the page 🙈) and it's dated October 2026 — struct pisp_be_cac_extra(9), out. slay 💅✨
