💅 zynq_slcr_write(9) — from the Kernel API Manual, bestie 🎀

okay so real talk, this is a page straight out of the Kernel API Manual, and it's about one tiny function that does one big job: writing to a register in the SLCR block. yes THAT SLCR block. we ride at dawn ✨

---

🌸 NAME 🌸

zynq_slcr_write — literally just write to a register in the SLCR block. that's it. that's the whole vibe. no cap 💅

---

🦋 SYNOPSIS 🦋

int zynq_slcr_write (u32 val , u32 offset );

look at her. two arguments, returns an int. iconic behavior honestly 🫶

---

🍓 ARGUMENTS 🍓

• val — the value you're writing to the register. the payload. the main character of this operation 👑
• offset — the register offset in the SLCR block, i.e. where in the block you're dropping that value 📍

⭐ RETURN ⭐

so what does she give back?

• a negative value on error 😭
• 0 on success ✨ slay

fr fr, check the return value. negative means something went sideways and you should absolutely not ignore it 🙈
