stmmac_axi_blen_to_mask(9)

💅 stmmac_axi_blen_to_mask — the Kernel API Manual moment 🎀

okay so bestie, we're in the stmmac_axi_blen_to_mask(9) page and honestly? it's a little baby function with one job and it does it flawlessly. no cap. let's get into it ✨

---

✨ NAME ✨

stmmac_axi_blen_to_mask — convert a burst length array to a reg value 🦋

like, it takes your burst lengths and turns them into one shiny register value. that's the whole vibe. that's the assignment and it ATE. 💅

---

🌸 SYNOPSIS 🌸

void stmmac_axi_blen_to_mask (u32 *regval , const u32 *blen , size_t len );

returns void, so no "did it work" little return value to obsess over — it just does the thing. periodt. ✨

---

💖 ARGUMENTS 💖

• regval — pointer to a u32 for the resulting register value 🎀 — this is the main character, it's where the answer goes.
• blen — pointer to an array of u32 containing the burst length values in bytes 🌈 — yes, bytes, not vibes.
• len — the number of entries in the blen array ⭐ — like, how many of them you actually packed in there.
