iavf_force_wb(9)

✨ iavf_force_wb(9) ✨

okay so bestie, welcome to the iavf_force_wb page from the Kernel API Manual 💖 this is a lil corner of the iavf driver docs and it's honestly so straightforward it's giving "one job and she DOES it" energy 👑

---

🌸 NAME 🌸

iavf_force_wb — Issue SW Interrupt so HW does a wb 💅

like, literally the whole personality. we poke the hardware with a software interrupt so it actually goes and does a writeback. no cap. 🔥

---

🦋 SYNOPSIS 🦋

void iavf_force_wb (struct iavf_vsi *vsi , struct iavf_q_vector
*q_vector );

returns nothing (void), takes two pointers, done and dusted ✨

---

🎀 ARGUMENTS 🎀

• vsi — the VSI we care about 🫶 (yes, this one, the one we're emotionally invested in)
• q_vector — the vector on which to force writeback ⚡ like, this is the exact vector getting the forced wb treatment, no substitutions please

ok quick vibe check: this page has no OPTIONS section, no DESCRIPTION section, no exit statuses, no files beyond that one source file, and no warnings or bug notes — it's a short king and we respect that 👑 don't go looking for lore that isn't there 🙈

and that's the whole page bestie, mwah 💋 sending you off with love from ./drivers/net/ethernet/intel/iavf, dated October 2026, straight out of the Kernel API Manual — see you in the next one, periodt 🎀✨🦋💜
