STRUCT XSDFEC_CONFIG(9)

💖 struct xsdfec_config(9) 💖

okay bestie, so this is a page straight out of the Kernel API Manual — it's all about struct xsdfec_config, which is literally the configuration of the SD-FEC core. no cap, that's the whole vibe. 🦋

✨ SYNOPSIS ✨

here's the shape of it, keep it exact bestie:

struct xsdfec_config {
    __u32 code;
    __u32 order;
    __u32 din_width;
    __u32 din_word_include;
    __u32 dout_width;
    __u32 dout_word_include;
    struct xsdfec_irq irq;
    __s8 bypass;
    __s8 code_wr_protect;
 };

🎀 Members 🎀

• code — the codes that the SD-FEC instance is using rn 👑
• order — the Order of Operation, iconic behavior only
• din_width — the width of the DIN AXI4-Stream 🌈
• din_word_include — tells you how DIN_WORDS get inputted, iykyk
• dout_width — the width of the DOUT AXI4-Stream ⭐
• dout_word_include — HOW DOUT_WORDS are outputted (yes it's shouting, that's how it is 💅)
• irq — enabling or disabling interrupts, the drama switch 🔥
• bypass — is the core being bypassed? main character question fr fr
• code_wr_protect — is write protection of LDPC codes enabled? 🧚

and like, a lil sign-off: this one lives at ./include/uapi/misc, dated October 2026, and she's officially struct xsdfec_config(9). periodt. 🫶🌈💜
