💅 dma_buf_attach(9) — Kernel API Manual ✨

okay so bestie, welcome to the dma_buf_attach page 💖 this is a lil kernel API doc, and honestly? it's short, it's sweet, it's giving "one-line wrapper that does exactly what it says." let's get into it 🎀

🌸 NAME 🌸

dma_buf_attach — literally just a wrapper for dma_buf_dynamic_attach, no cap 🫶

✨ SYNOPSIS ✨

struct dma_buf_attachment * dma_buf_attach (struct dma_buf *dmabuf ,
struct device *dev );

that's the whole vibe — you hand it a buffer and a device, you get back a struct dma_buf_attachment * 💅

🦋 ARGUMENTS 🦋

  • dmabuf [in] — the buffer you wanna attach your device to 🍓 ngl this is the star of the show.
  • dev [in] — the device that's getting attached. the main character, if you will 👑.

💜 DESCRIPTION 💜

okay so here's the tea ☕: this is a wrapper that calls dma_buf_dynamic_attach for drivers that still use a static mapping 🌈. that's it. that's the whole function. it's iconic in its simplicity, fr fr 😭

lowkey important ✨ — it exists for the drivers still on static mappings. if that's you, this is your girl. if not, maybe slide over to dma_buf_dynamic_attach(9) iykyk 💅
