STRUCT XSDFEC_TURBO(9)

💅 struct xsdfec_turbo(9) — the Kernel API Manual, but make it cute

okay so bestie, welcome to the glow-up of struct xsdfec_turbo(9) from the Kernel API Manual — yes that one, the Xilinx SDFEC corner of the kernel tree 🌸 she's giving "small struct, big main character energy" and we're gonna get into it.

---

✨ NAME ✨

struct xsdfec_turbo — literally the user data for Turbo codes 🌀 no cap.

---

🎀 SYNOPSIS 🎀

struct xsdfec_turbo {
    __u32 alg;
    __u8 scale;
 };

that's it. that's the whole struct. two fields. iconic minimalism fr fr 💖

---

🦋 Members 🦋

• alg — says which Turbo decode algorithm you're gonna use. that's the whole job. it ate. ✨
• scale — the extrinsic scaling to apply when the Max Scale algorithm has been selected. so like, scale is only doing its thing in that specific scenario, iykyk. 🔥

---

💜 Description 💜

it's the Turbo code structure 💫 — her entire purpose in life is to communicate parameters over to the XSDFEC driver. that's it, that's the vibe check, she passed, periodt 👑
