ibmvscsi_resume(9)

💖 ibmvscsi_resume(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ today's main character is ibmvscsi_resume(9) — the lil function that gets your adapter back on its feet after a suspend. she's short, she's sweet, she's lowkey doing the most important thing. let's get into it 🫶

---

✨ NAME ✨

ibmvscsi_resume — literally just: Resume from suspend 🌸

---

🦋 SYNOPSIS 🦋

int ibmvscsi_resume (struct device *dev );

that's it. that's the whole signature. short queen behavior 💅

---

🎀 ARGUMENTS 🎀

• dev — the device struct, aka the device she's resuming. hand her the device and let her cook 🍓

---

👑 DESCRIPTION 👑

so here's the tea ☕ — when you suspend/resume, we may have lost an interrupt along the way 😭 like it just ghosted us. so what does she do? she kicks the interrupt handler 🔥 to get things flowing again. no cap, that's the whole vibe. not me being obsessed with a three-line function 💀

ngl this is one of those "small but crucial" moments — the interrupt handler does NOT get to take a nap forever, bestie is waking it UP 🙈
