bnx2x_int_disable_sync(9)

💅 bnx2x_int_disable_sync(9) — the "okay everyone, interrupts OFF, nobody move" moment

bestie, welcome to the Kernel API Manual entry for bnx2x_int_disable_sync, and trust me, this one is short but it's doing something real. 🫶

---

✨ NAME ✨

bnx2x_int_disable_sync — disable interrupts. that's it. that's the whole name. iconic brevity honestly. 💅

---

🌸 SYNOPSIS 🌸

void bnx2x_int_disable_sync (struct bnx2x *bp , int disable_hw );

like, it returns nothing (void, she's not giving you a status report, she's just doing the thing) and it takes two args. slay.

---

🎀 ARGUMENTS 🎀

• bp — the driver handle. your bnx2x bestie. hold onto it. 💖
• disable_hw — true, disable HW interrupts. yes literally pass true for that. 🙈

---

🦋 DESCRIPTION 🦋

okay so here's the vibe: this function ensures that there are no ISRs or SP DPCs (sp_task) running after it returns.

read that again. after it returns. not "probably not running", not "we asked nicely", but like — when this bad girl comes back, there is nothing still going. no ISRs, no SP DPCs, sp_task included. that's the whole point of the _sync in the name and honestly it ate. 🔥

ok real talk for one sec: this is the :9 kernel API section, so it's describing an in-kernel function interface — aka documentation for people writing or reading driver code, not a command you run in your shell. don't go typing bnx2x_int_disable_sync into a terminal and expecting a vibe check back. 😭

and that's the page, bestie! this masterpiece comes to you from source ./drivers/net/ethernet/broadco... and it's dated October 2026 — so yeah, she's timestamped and official, mwah. 💋🌸 go forth and disable those interrupts responsibly ✨👑
