💖 irdma_puda_alloc_buf (9) — the kernel API manual, bestie edition ✨

okay so. this is a page from the Kernel API Manual, and no, we're not skipping it, because the PUDA buffer allocation is honestly kind of a big deal. sit down, get a lil snack 🍓, and let me tell you about the one (1) function that grabs you some memory for a buffer.

🌸 NAME 🌸

irdma_puda_alloc_buf — literally just: allocate mem for buffer. that's the whole vibe. it hands you a buffer. 💅

🦋 SYNOPSIS 🦋

struct irdma_puda_buf * irdma_puda_alloc_buf (struct irdma_sc_dev *dev ,
u32 len );

so it takes two things and it gives you back a struct irdma_puda_buf *. no cap. 🫶

✨ ARGUMENTS ✨

  • dev — the iwarp device 👑 like, THE main character here. it's a struct irdma_sc_dev *.
  • len — length of buffer 📏 a u32, so you tell it how much you want.
