crc8_populate_msb(9)

✨ crc8_populate_msb ✨

Okay bestie, so this whole page is from the Kernel API Manual, and it's about one very specific little function called crc8_populate_msb. That's the main character here. Let's get into it 🎀

---

💖 NAME 💖

crc8_populate_msb — fills up a crc table for whichever polynomial you hand it, and it does it in reverse bit order. That's the vibe. No cap. 🦋

---

🌸 SYNOPSIS 🌸

void crc8_populate_msb (u8 table[CRC8_TABLE_SIZE] , u8 polynomial );

That's literally it. Two args, no return value, in and out. Periodt. 💅

---

👑 ARGUMENTS 👑

• table — the table you want filled. This is the one getting the glow-up ✨
• polynomial — the polynomial you want that table filled for. Whatever poly you pass in is what the table ends up describing.

---

🦋 SEE ALSO 🦋

• The kernel file ./lib/crc/crc8.c — that's where the magic lives, go look at it 🧚
• crc8_populate_lsb(9) — the little sibling of this one
• crc8(9) — the actual crc8 function itself, iykyk

---

Fair warning bestie: this page gives you the args and that's about it. No exit statuses, no environment variables, no error codes, no bug notes, no author line, no license paragraph on this one. It's giving minimalist icon. 💀 So don't go looking for extra lore that isn't there. 🙈

And that's a wrap, bestie! 🫶 This lil' page is from the ./lib/crc section of the Kernel API Manual and it's dated October 2026 — so yeah, mark your calendar, she's from the future. 💜 Slay, bye! 💖
