init_rs(9)

init_rs(9) ✨

okay so bestie, welcome to the Kernel API Manual page for init_rs(9) — this one is all about creating a RS control struct and getting it initialized. it's giving “small function, important setup,” and we're gonna read it together 💖

🌸 NAME 🌸

init_rs — create a RS control struct and initialize it, periodt ✨

✨ SYNOPSIS ✨

struct rs_control * init_rs (int symsize , int gfpoly , int fcr , int prim , int nroots );

🎀 ARGUMENTS 🎀

• symsize — the symbol size (number of bits). literally the bit-count vibe for each symbol 💅
• gfpoly — the extended Galois field generator polynomial coefficients, with the 0th coefficient in the low order bit. and bestie, the polynomial must be primitive — no cap, that part is non-negotiable 🫶
• fcr — the first consecutive root of the rs code generator polynomial in index form. iconic index-form behavior ✨
• prim — primitive element to generate polynomial roots. yes ma'am, roots are getting generated 🌱
• nroots — RS code generator polynomial degree (number of roots). so like, the degree, aka the number of roots 🎀

💜 DESCRIPTION 💜

Allocations use GFP_KERNEL.

that's the description, bestie — short, sweet, and fully booked with GFP_KERNEL energy 💫
