hwif_ready(9)

💅 hwif_ready — test if the HW is ready for use

okay so this is a page straight out of the Kernel API Manual, and it's about checking whether the hardware is, like, actually awake and ready to be used. not me being dramatic, it's literally called hwif_ready. bestie, it's a vibe check for hardware. 🦋

---

✨ SYNOPSIS ✨

int hwif_ready (struct hinic_hwif *hwif );

it returns an int, it takes exactly one thing, and honestly the name ate. 🔥

---

🎀 ARGUMENTS 🎀

• hwif — the HW interface of a pci function device. that's the whole argument, no notes, she's the main character here. 👑

---

🌸 DESCRIPTION 🌸

so here's the tea: this function gives you the verdict on whether the HW is ready for use, and it reports that verdict through its return value.

• returns 0 — Success 💖 (yay, we're so back)
• returns a negative value — Failure 😭 (it's giving not ready)

no cap, that's the entire contract: 0 good, negative bad. if you get a negative number back, do not pass go, do not start using the hardware, periodt. 💀
