💅 dspload_image(9) — Kernel API Manual 🎀

okay so bestie, welcome to the page about dspload_image — it downloads the DSP from a DSP Image Fast Load structure. that's the whole vibe. let's get into it ✨

✨ NAME ✨

dspload_image — Download DSP from a DSP Image Fast Load structure. literally what it says on the tin, no cap 💖

🌸 SYNOPSIS 🌸

int dspload_image (struct hda_codec *codec , const struct dsp_image_seg
*fls , bool ovly , unsigned int reloc , bool autostart , int
router_chans );

🦋 ARGUMENTS 🦋

  • codec — the HDA codec. that's your main character rn 💅
  • fls — pointer to a fast load image. yes pointed, yes iconic 🎀
  • ovly — TRUE if overlay format is required. gotta be true-or-false about it fr fr
  • reloc — Relocation address for loading single-segment overlays, or 0 for no relocation. zero means "chill, no relocating happening here" 🌸
  • autostart — TRUE if DSP starts after loading; ignored if ovly is TRUE. so if ovly is true, this argument is just standing there with no job 😭
  • router_chans — number of audio router channels to be allocated (0 means use internal defaults; max is 32). so like, pick a number, but 32 is the ceiling bestie, don't push it 🫶

🔥 DESCRIPTION 🔥

Download DSP from a DSP Image Fast Load structure. 🎧

the way this works: that structure is a linear, non-constant sized element array of structures, and each one of them contains:

  • the count of the data to be loaded
  • the data itself
  • the corresponding starting chip address of the starting data location

Returns zero or a negative error code. so like, 0 = slay, negative = not slay 💀

👑 SEE ALSO 👑

go check out the Kernel file ./sound/hda/codecs/ca0132.c — and while you're in there, these besties are linked too:

ngl bestie, read the SEE ALSO before you go poking at the DSP, it's giving "you'll want the context" 🙈
