__genwqe_writel(9)

💅 __genwqe_writel(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for __genwqe_writel(9), and honestly? it's giving "one job, does it well." ✨

---

🌸 NAME 🌸

__genwqe_writel — Write 32-bit register 🎀

like, that's it. that's the whole vibe. you write a 32-bit value into a register. slay.

---

🦋 SYNOPSIS 🦋

int __genwqe_writel (struct genwqe_dev *cd , u64 byte_offs , u32 val );

not me being obsessed with how clean that signature is 😭 three args, one int coming back at you.

---

✨ ARGUMENTS ✨

• cd — the genwqe device descriptor 💖 this is your main character, the device you're talking to.
• byte_offs — byte offset within BAR 🧚 that's where in the BAR you're aiming, measured in bytes.
• val — the 32-bit value 💅 the actual thing you're writing. 32 bits of pure content.

---

🔥 RETURN 🔥

• 0 if success 🫶
• < 0 if error 💀

that's the whole contract, no cap. zero means we ate. negative means something went sideways.
