STRUCT FSL_EASRC_CTX_PRIV(9)

✨ struct fsl_easrc_ctx_priv(9) ✨

okay so bestie, welcome to the Kernel API Manual — today we're looking at struct fsl_easrc_ctx_priv, which is literally the EASRC context private data 🎀. it's giving "the little struct that holds the whole vibe together" and honestly? obsessed.

🌸 NAME 🌸

struct fsl_easrc_ctx_priv — EASRC context private data 💅

🦋 SYNOPSIS 🦋

struct fsl_easrc_ctx_priv {
    struct fsl_easrc_io_params in_params;
    struct fsl_easrc_io_params out_params;
    unsigned int st1_num_taps;
    unsigned int st2_num_taps;
    unsigned int st1_num_exp;
    unsigned int pf_init_mode;
    unsigned int rs_init_mode;
    unsigned int ctx_streams;
    u64 rs_ratio;
    u64 *st1_coeff;
    u64 *st2_coeff;
    int in_filled_sample;
    int out_missed_sample;
    int st1_addexp;
    int st2_addexp;
    int ratio_mod;
    unsigned int in_filled_len;
 };

no cap, that's the whole shape of it — copy it exactly, don't be out here freestyling the field names 😭

👑 Members 👑

• in_params — input parameter. that's the input side's whole situation fr fr 🫶
• out_params — output parameter. the output side said "my turn" 💖
• st1_num_taps — tap number of stage 1 ✨
• st2_num_taps — tap number of stage 2 ✨ (yes there's a stage 2, we love a sequel)
• st1_num_exp — exponent number of stage 1 🔥
• pf_init_mode — prefilter init mode. the prefilter's main character energy setting 😌
• rs_init_mode — resample filter init mode. same but for the resample filter, iykyk
• ctx_streams — stream flag of ctx 🌈
• rs_ratio — resampler ratio, lowkey the moment ⭐
• st1_coeff — pointer of stage 1 coeff 🧚
• st2_coeff — pointer of stage 2 coeff 🧚 (both of them are pointers, both of them are iconic)
• in_filled_sample — input filled sample 🍓
• out_missed_sample — sample missed in output 🙈
• st1_addexp — exponent added for stage1 💜
• st2_addexp — exponent added for stage2 💜
• ratio_mod — update ratio 👑
• in_filled_len — input filled length 🌸

okay quick vibe check before you go: every one of those field descriptions is doing the work, so if you're reading the header you already know what's up. don't skip any of them 💀
