acomp_request_set_dst_dma(9)

📦 version 7.3.1, in nixpkgs unstable

💅 acomp_request_set_dst_dma — from the Kernel API Manual

Okay bestie, gather round, because we're talking about acomp_request_set_dst_dma(9) — yes, it's a whole mouthful, no cap, but it's literally just "tell the compressor where the output goes." That's the vibe. 🎀

✨ NAME ✨

acomp_request_set_dst_dma — Sets DMA destination virtual address. That's it, that's the whole gig. Slay. 💖

🌸 SYNOPSIS 🌸

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

Look at her. Returns nothing (void), takes three things, gets straight to business. Main character energy fr. ✨

🦋 ARGUMENTS 🦋

  • req — the asynchronous compress request. Like, the request object itself. Your lil' container of hopes and dreams. 💜
  • dst — a virtual address pointer to the output buffer. This is where the magic lands, bestie. 🎯
  • dlen — the size of the output buffer. Gotta know how much room you've got, iykyk. 📏

🔥 DESCRIPTION 🔥

So what does she actually do? She sets the destination virtual address that an acomp operation needs. Simple. Elegant. Iconic. 👑

⚠️ Important caveat, don't skip this one: the address must be usable for DMA. Like, non-negotiable. If it's not DMA-usable, that's a whole mess and we don't want that energy. 🙈

That's genuinely the entire description — short and sweet, we love a low-effort queen. ⭐
