__genwqe_readq(9)

💅 __genwqe_readq — read that 64-bit register, bestie

okay so this is a page from the Kernel API Manual (section 9, kernel-space girlies only ✨), and it's literally the tiniest little function and she still ate. it's __genwqe_readq. the double underscore is not a typo, it's a whole lewk 👑

🌸 NAME 🌸

__genwqe_readq — Read 64-bit register

like, that's it. that's her whole job. read a 64-bit register. iconic honestly 🎀

---

✨ SYNOPSIS ✨

u64 __genwqe_readq (struct genwqe_dev *cd , u64 byte_offs );

so she takes two things and she hands you back a u64. no cap 🫶

---

🦋 ARGUMENTS 🦋

• cd — the genwqe device descriptor. this is your main character struct, the whole device vibe check in one pointer 💖
• byte_offs — the offset within BAR. yes, byte offset, so don't come at her with word offsets, she's not doing that math for you 🙈

---

⭐ RETURN ⭐

value from register. that's the answer. that's the whole tea. she reads it and she gives it to you 🔥
