STRUCT FIMC_DMA_OFFSET(9)

✨ struct fimc_dma_offset(9) ✨

okay bestie, we're diving into the Kernel API Manual for struct fimc_dma_offset — yes it's a real kernel thing, yes it's from the Exynos4 FIMC world, and yes we're gonna understand it together 🫶

---

💖 NAME 💖

struct fimc_dma_offset — literally just pixel offset information for DMA. That's the whole vibe. It's a little bag of numbers that tells the DMA engine how far to nudge each colour plane's pixels around. 🎀

🌸 SYNOPSIS 🌸

       struct fimc_dma_offset {
           int y_h;
           int y_v;
           int cb_h;
           int cb_v;
           int cr_h;
           int cr_v;
        };

🦋 Members 🦋

so this struct is basically a little friend group of six ints, and each one is an offset for one plane in one direction. no cap, that's it:

• y_h — the horizontal offset for the y value ✨
• y_v — the vertical offset for the y value ✨
• cb_h — the horizontal offset for the cb value 💜
• cb_v — the vertical offset for the cb value 💜
• cr_h — the horizontal offset for the cr value 🌈
• cr_v — the vertical offset for the cr value 🌈

like, _h is horizontal, _v is vertical, and y / cb / cr are your three planes. it's giving "consistent naming, we love to see it" 💅

💀 reminder bestie: these are the exact names, spelled exactly like that. don't you dare "fix" the fimc prefixes, they're iconic and load-bearing.
