dspxfr_image(9)

💅 dspxfr_image — like, the whole DSP image gets written to DSP memory, bestie

okay so this is dspxfr_image(9) from the Kernel API Manual, and it's literally the function that takes your entire DSP image — like a full DSP code/data overlay — and writes it to DSP memories. it's giving "all at once, no crumbs left behind." 🎀

---

✨ SYNOPSIS ✨

int dspxfr_image (struct hda_codec *codec , const struct dsp_image_seg
*fls_data , unsigned int reloc , unsigned int sample_rate , unsigned
short channels , bool ovly );

like yes she's a little long, she's worth it 💖

🌸 ARGUMENTS 🌸

• codec — the HDA codec. that's her. that's the main character 🫶
• fls_data — pointer to a fast load image ✨ (fr, it's the image)
• reloc — the relocation address for loading single-segment overlays, or 0 for no relocation. so either you're relocating or you're not, no in-between 💅
• sample_rate — sampling rate of the stream used for DSP download 🎵
• channels — channels of the stream used for DSP download 🎧
• ovly — TRUE if overlay format is required. TRUE, okay? not "true-ish," not "maybe," TRUE 👑

---

🦋 DESCRIPTION 🦋

so what does she return? returns zero, or a negative error code. that's it, that's the whole vibe check. zero means slay, negative means 😭.

no cap, that's genuinely all the manpage says about behavior — I'm not gonna invent lore that isn't there 🙈

ngl bestie, if you're poking at dspxfr_image you're already deep in the DSP lore. drink some water, read the source, and remember: 0 is a win 💀✨
