🎀 init_rs_non_canonical — kernel API manual, bestie edition 🎀

So you found yourself in the init_rs_non_canonical(9) zone, huh? Okay so this is the kernel API manual page for it, and I'm gonna walk you through it like we're texting at 2am. Buckle up, it's giving ✨Reed-Solomon✨.

✨ NAME ✨

init_rs_non_canonical — allocate an rs control struct for fields with non-canonical representation 💅

Like, it's the allocator for the rs control struct, but specifically for the non-canonical-representation fields. Not the canon ones. The other ones. iykyk 🦋

🌸 SYNOPSIS 🌸

struct rs_control * init_rs_non_canonical (int symsize , int
       (*gffunc)(int) , int fcr , int prim , int nroots );

That's the whole signature, no cap. It hands you back a struct rs_control * pointer, and it takes five things. Five! Let's meet them 👑

💖 ARGUMENTS 💖

  • symsize — the symbol size, aka the number of bits. That's it, that's the vibe. 🧚
  • gffunc — a pointer to the function that generates the next field element, or the multiplicative identity element if it's given 0. Literally the glow-up replacement: this gets used instead of gfpoly whenever gfpoly is 0. Slay. 🫶
  • fcr — the first consecutive root of the rs code generator polynomial, but in index form. Don't ask me to convert it, ask the index form. 📇
  • prim — the primitive element used to generate the polynomial roots. Main character energy honestly. 👑
  • nroots — the RS code generator polynomial degree, which is also the number of roots. Two facts, one argument, we love efficiency. 🔥

Go read them, they're iconic too, periodt. 💜

Okay so quick vibe check: this page is straight from the ./lib/reed_solomon part of the kernel tree, dated October 2026, and the page itself is init_rs_non_canonical(9). That's the whole sign-off bestie, mwah 💋🌈⭐
