cs_amp_write_cal_coeffs(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the cs_amp_write_cal_coeffs(9) page, straight outta the Kernel API Manual. it's giving “tiny function, very important firmware business” energy, and we're gonna get into all of it. 🎀

💅 NAME 💅

cs_amp_write_cal_coeffs — literally just write calibration data to firmware controls. that's the whole assignment, and it ate. ✨

✨ SYNOPSIS ✨

int cs_amp_write_cal_coeffs (struct cs_dsp *dsp , const struct
       cirrus_amp_cal_controls *controls , const struct cirrus_amp_cal_data
       *data );

🦋 ARGUMENTS 🦋

  • dsp — pointer to struct cs_dsp. yes ma'am, that's the dsp situation. 💖
  • controls — pointer to the definition of firmware controls to be written. the firmware-controls blueprint, basically. 🎀
  • data — pointer to calibration data. the actual calibration data bestie, no cap. 🌸

🔥 RETURN 🔥

0 on success, else a negative error value. so like… zero is the slay outcome, negative means something went nope. 😭
