💖 cs_dsp_adsp2_init(9) — Kernel API Manual, bestie edition 💖

okay so picture this: you're in the kernel, you've got a cs_dsp struct that's supposed to be out here representing a whole ADSP2 core, and it's just sitting there uninitialised like a phone with 1% battery. this is the function that fixes that. it's from the Kernel API Manual (cs_dsp_adsp2_init(9)), and yes it's as iconic as it sounds ✨

🌸 NAME 🌸

cs_dsp_adsp2_init — literally the "Initialise a cs_dsp structure representing a ADSP2 core" moment. that's the whole vibe. you hand it a DSP struct, it makes it an ADSP2 core. slay.

✨ SYNOPSIS ✨

int cs_dsp_adsp2_init (struct cs_dsp *dsp );

she takes exactly one argument and returns an int. no cap. 🫶

🎀 ARGUMENTS 🎀

  • dsp — pointer to the DSP structure 💅 that's it, that's the whole list. this is the struct cs_dsp * she's gonna initialise, so bestie please make sure it's a real pointer and not whatever you had lying around 🙈

🦋 RETURN 🦋

  • Zero — success!! we love a glow-up 🎉
  • a negative number — error 😭 that's it, that's the contract. no funky positive codes, no "it depends", just zero or negative. periodt.
