📦 version 7.3.1, in nixpkgs unstable

💖 fm10k_fifo_init 💖

okay so this is a page from the Kernel API Manual, bestie — fm10k_fifo_init(9) — and it's literally the moment your message FIFO gets its whole life together ✨

🌸 NAME 🌸

fm10k_fifo_init — Initialize a message FIFO 🎀

like, it sets the whole thing up. the origin story. the glow-up. periodt.

🦋 SYNOPSIS 🦋

void fm10k_fifo_init (struct fm10k_mbx_fifo *fifo , u32 *buffer , u16
size );

no cap, that's the whole signature — go off, void 💅

✨ ARGUMENTS ✨

  • fifo — pointer to FIFO 🫶 this is the lil struct you're bringing to life.
  • buffer — pointer to memory to be used to store FIFO 💾 that's the actual space where the messages live, so give it somewhere nice to stay.
  • size — maximum message size to store in FIFO, must be 2^n - 1 🔥 and yes that "must" is doing a LOT of work, so respect the power-of-two-minus-one rule or it's giving bug energy.
⚠️ real talk: size has to be 2^n - 1. not vibes-based. not negotiable. it's in the spec, iykyk.
