acomp_reques...t_dst_nondma(9)

💅 acomp_request_set_dst_nondma(9) 💅

okay so bestie, welcome to the Kernel API Manual page for acomp_request_set_dst_nondma(9) — it's giving very specific destination-address energy and we're gonna get into it. ✨

---

🌸 NAME 🌸

acomp_request_set_dst_nondma — sets the non-DMA destination virtual address. That's the whole vibe, no cap. 💖

---

🎀 SYNOPSIS 🎀

void acomp_request_set_dst_nondma (struct acomp_req *req , u8 *dst ,
       unsigned int dlen );

---

🦋 ARGUMENTS 🦋

• req — the asynchronous compress request, aka the main character here 👑
• dst — virtual address pointer to the output buffer, where the destination lives 💫
• dlen — size of the output buffer, so we know how much room we're working with 📏

---

🌈 DESCRIPTION 🌈

So this function sets the destination virtual address that an acomp operation needs. Simple, iconic, to the point. 🫶

The address can not be used for DMA — like, that is literally not its lane. Keep that in mind, bestie, because it matters. 💅
