genwqe_card_type(9)

💅 NAME

genwqe_card_type — bestie, this is literally The Function that gets you the chip type from the SLU Configuration Register 🎀

Quick context before we dive in: this whole page lives in the Kernel API Manual, and it's all about genwqe_card_type(9). K? K. Let's go. ✨

🦋 SYNOPSIS

u8 genwqe_card_type (struct genwqe_dev *cd );

Yes the spicy space before the closing paren is exactly how the original writes it, don't come for me 🙈 Keep it verbatim, she's iconic like that.

---

🎀 ARGUMENTS

• cd — pointer to the genwqe device descriptor. That's it. That's the whole argument list. One (1) pointer, zero drama, we love a low-maintenance signature 💅

---

🌸 RETURN

You get back a u8, and the value tells you which chip you're dealing with. No cap, here's the full mapping:

1. 0 — Altera Stratix-IV 230
2. 1 — Altera Stratix-IV 530
3. 2 — Altera Stratix-V A4
4. 3 — Altera Stratix-V A7

Four chips, four numbers, zero chaos. Slay. 👑

Heads up bestie: those are the only values the page documents, so don't go inventing a 4 and expecting me to validate it. 🫶
