STRUCT CAMIF_DMA_OFFSET(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… struct camif_dma_offset(9)

okay so bestie, welcome to the Kernel API Manual ✨ β€” yes we're reading kernel headers for fun now, this is who we are, and honestly? iconic behavior. today's main character is struct camif_dma_offset, and it's literally just two ints doing pixel math, no cap πŸŽ€


🌸 NAME 🌸

struct camif_dma_offset β€” pixel offset information for DMA πŸ¦‹

like, that's it. that's the whole vibe. it's the little struct that tells the DMA engine where pixels start and where lines end. lowkey important, highkey tiny πŸ’–


✨ SYNOPSIS ✨

struct camif_dma_offset {
    int initial;
    int line;
 };

not me copying it exactly, character for character, because that's the whole point πŸ™ˆ the code stays perfectly as-is, only the commentary gets the glow-up πŸ’…


🫢 Members 🫢

okay so this is the part where we meet the two icons in the struct, and they are both int, and they are both about pixels:

  • initial β€” the offset (in pixels) to the first pixel 🌟 like, where does the actual picture start? this one knows.
  • line β€” the offset (in pixels) from the end of the line to the start of the next line πŸŽ€ the lil gap between "done with this row" and "okay next row, let's go" ✨

two members, two jobs, no overlap, we love a clean division of labor πŸ‘‘


πŸ‘€ SEE ALSO πŸ‘€

go look at the kernel file ./drivers/media/platform/samsung/s3c-camif/camif-core.h β€” that's where this whole situation lives, fr fr πŸ“

and these besties are all in the same friend group:

  • struct camif_fmt(9)
  • struct camif_frame(9)
  • struct s3c_camif_variant(9)
  • struct camif_vp(9)
  • struct camif_dev(9)
  • struct camif_addr(9)
  • struct camif_buffer(9)

iykyk, it's giving "the entire camif cinematic universe" 🌈


ngl bestie, if you're here it's because you're deep in the Samsung s3c-camif driver and you need to know exactly where your pixels land. that's valid. that's growth. πŸ’€

and that's the tea πŸ“ this little page came to you from ./drivers/media/platform/samsu... and it's dated October 2026, still signed struct camif_dma_offset(9) at the bottom because some things never change πŸ’œ byeee, go read more headers, I'm obsessed with you πŸ§šβ€β™€οΈβœ¨
