q6asm_map_memory_regions(9)

💅 q6asm_map_memory_regions — the Kernel API Manual (section 9, bestie) 🎀

okay so picture this: you're deep in the kernel, section 9 of the manual, and this little icon is the one that maps memory regions in the dsp. yes. the dsp. we love her. ✨

✨ NAME ✨

q6asm_map_memory_regions — map memory regions in the dsp. that's it, that's the whole vibe. 💖

---

🌸 SYNOPSIS 🌸

int q6asm_map_memory_regions (unsigned int dir , struct audio_client *ac
, phys_addr_t phys , size_t period_sz , unsigned int periods );

like, five whole arguments. she's high maintenance but she's worth it. 👑

---

🦋 ARGUMENTS 🦋

• dir — direction of audio stream. which way are we going, bestie? 👉👈
• ac — audio client instanace. (that's the typo from the original, not me — keeping it 💀) your audio client, your main character.
• phys — physical address that needs mapping. this is the address. the physical one. ngl she's kind of the whole point. 🔥
• period_sz — audio period size. how big is each period, bestie? 📏
• periods — number of periods. how many of them. counting is free. 🍓

⭐ RETURN ⭐

Will be an negative value on failure or zero on success. like, zero = slay, negative = not slay. that's the whole system, no cap. 💀✨
