💜 i40e_write_dword(9) 💜

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, and yes, we're really doing this. this one's a function page for i40e_write_dword, and it's lowkey a tiny little helper doing one very specific glow-up job. let's get into it 🫶

---

✨ NAME ✨

i40e_write_dword — replace HMC context dword 💅

like, it swaps out a dword in your HMC context. that's the whole vibe. no cap.

---

🌸 SYNOPSIS 🌸

void i40e_write_dword (u8 *hmc_bits , struct i40e_context_ele *ce_info ,
u8 *src );

she returns void, she takes three args, she's booked and busy ⭐

---

🎀 ARGUMENTS 🎀

• hmc_bits — pointer to the HMC memory 🧠✨ this is the destination bestie, the place where the bits live
• ce_info — a description of the struct to be read from 📋
• src — the struct to be read from 🍓

not me noticing ce_info and src have literally the same one-line description 🙈 that's exactly what the page says though, so we're keeping it fr fr — no editorialising, just vibes and accuracy
