init_rs_gfp(9)

🌸 NAME 🌸

okay so this is init_rs_gfp(9) from the Kernel API Manual, and bestie, it’s literally here to create a RS control struct and initialize it ✨ That’s the whole vibe: make the struct, init it, slay 💅

✨ SYNOPSIS ✨

struct rs_control * init_rs_gfp (int symsize , int gfpoly , int fcr ,
       int prim , int nroots , gfp_t gfp );

🎀 ARGUMENTS 🎀

• symsize — the symbol size, aka the number of bits 🧚
• gfpoly — the extended Galois field generator polynomial coefficients, with the 0th coefficient in the low order bit. The polynomial must be primitive — no cap, that’s a hard requirement 💀
• fcr — the first consecutive root of the rs code generator polynomial, in index form 🌈
• prim — primitive element to generate polynomial roots 🔥
• nroots — RS code generator polynomial degree, aka the number of roots 👑
• gfp — memory allocation flags 🫶
