STRUCT FSL_EASRC_PRIV(9)

🌈 struct fsl_easrc_priv(9) 🌈

okay bestie, welcome to the Kernel API Manual — today's main character is struct fsl_easrc_priv, and it is literally the private data holder for EASRC. no cap, she's got a lot going on but we're gonna get through it together 🫶

✨ NAME ✨

struct fsl_easrc_priv — EASRC private data 💅

🦋 SYNOPSIS 🦋

struct fsl_easrc_priv {
    struct fsl_easrc_slot slot[EASRC_CTX_MAX_NUM][2];
    struct asrc_firmware_hdr *firmware_hdr;
    struct interp_params *interp;
    struct prefil_params *prefil;
    const struct firmware *fw;
    const char *fw_name;
    unsigned int rs_num_taps;
    unsigned int bps_iec958[EASRC_CTX_MAX_NUM];
    u64 *rs_coeff;
    u64 const_coeff;
    int firmware_loaded;
 };

like, look at her. iconic struct. no notes 💜

🎀 Members 🎀

okay so let's meet the whole squad, one by one:

• slot — the slot setting, and yes she's an array: [EASRC_CTX_MAX_NUM][2], she contains multitudes ✨
• firmware_hdr — the header of firmware, the little crown on top 👑
• interp — pointer to interpolation filter coeff, pointing at the vibes
• prefil — pointer to prefilter coeff, the pre-game filter fr fr
• fw — firmware of coeff table, the whole coefficient table's firmware
• fw_name — firmware name, gov, it's literally just her name 😭
• rs_num_taps — resample filter taps, and the valid values are 32, 64, or 128 — those three, bestie, don't get creative 💀
• bps_iec958 — bits per sample of iec958, array of size EASRC_CTX_MAX_NUM 🎧
• rs_coeff — resampler coefficient, a u64 * of pure math
• const_coeff — one tap prefilter coefficient, a single u64, tiny but mighty 🌸
• firmware_loaded — firmware is loaded, the little int that tells you if we're so back or if we're not 🫶
