ISPI(4)

💅 ISPI(4) 💅

ok so this is a page from the Kernel Interfaces Manual — yes, the kernel interfaces manual, we're doing big-kid stuff today bestie, and the star of the show is ispi 💖

---

✨ NAME ✨

ispi — the Intel LPSS SPI controller. that's it, that's the whole name. short, iconic, no notes 🎀

---

🌸 SYNOPSIS 🌸

ispi* at acpi?
ispi* at pci?

so ispi can show up two ways — hanging off acpi? or hanging off pci?. pick your fighter, both are valid, the * and the ? are doing their whole wildcard thing exactly like you'd expect 🦋

---

🫶 DESCRIPTION 🫶

okay so real talk: the ispi driver supports the Serial Peripheral Interface (SPI) controller that's baked into the Intel Low-Power Subsystem (LPSS). that's the whole description bestie, it's a short one — lowkey the manpage equivalent of a clean five-second get-ready-with-me 🙈

ngl if you were hoping for a whole novel of options and flags, this is not that page. it's a device driver page. it does one thing and it does it 💅

---

🔥 SEE ALSO 🔥

• acpi(4) — the ispi driver can attach at acpi?, so go read this one
• pci(4) — and it can attach at pci? too, so this one's also your bestie

fr fr go read both, they're right there 👑

🌈 HISTORY 🌈

the ispi device driver first appeared in OpenBSD 7.9 ⭐ so it's genuinely new-new, fresh out the box, main character energy from day one 🧚
