✨ cvs_checksum(9) ✨

okay so bestie, welcome to cvs_checksum(9) from the Kernel API Manual — yes that's the section 9 girlies, kernel API hive rise 💅 this one's a little function with big "just add stuff up" energy and honestly? iconic.

🌸 NAME 🌸

cvs_checksum — a simple additive checksum helper 🎀 like literally that's the whole gig. it adds. it checksums. it slays.

🦋 SYNOPSIS 🦋

u32 cvs_checksum (const void *data , size_t len );

that's it, that's the whole vibe check 💖 returns a u32, takes a const void * and a size_t, no cap.

⭐ ARGUMENTS ⭐

  • data — a 32-bit aligned data buffer, bestie. aligned fr fr, don't come at it sideways 🙈
  • len — the length in bytes, and it's gotta be a multiple of 4 🔥 (makes sense, we're out here chewing through dwords)

👑 RETURN 👑

it hands you back a 32-bit additive checksum of all the dwords chillin' in data ✨ that's the whole tea 🍓

💜 SEE ALSO 💜

okay this is the part where I introduce you to the whole friend group 🫶 the kernel file lives at ./drivers/media/i2c/cvs/core.c, and here's everybody you should go say hi to:

no cap, that's the entire roster 💀 go read 'em, iykyk 📚

ngl, len not being a multiple of 4 is not the move — the page says multiple of 4, so respect the multiple of 4, periodt 💅

and that's the page, bestie!! 🧚 it's from ./drivers/media/i2c/cvs and it's dated October 2026 — so like, future girl summer 🌈 mwah, love u, go checksum something 💖🌺👑
