📦 version 7.3.1, in nixpkgs unstable

💅 ksz9477_acl_wait_ready(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the Microchip DSA driver, you just kicked off an ACL read or write, and now you're sitting there like 👀 waiting for the hardware to finish. That's this function. It's the "girl, are we done yet?" of kernel functions, and it's lowkey doing the lord's work.

✨ NAME ✨

ksz9477_acl_wait_ready — Waits for the ACL operation to complete on a given port.

Like literally, it waits. Patient queen behavior. 👑

🎀 SYNOPSIS 🎀

int ksz9477_acl_wait_ready (struct ksz_device *dev , int port );

🌸 ARGUMENTS 🌸

  • dev — The ksz_device instance. That's your whole switch vibe right there. 🫶
  • port — The port number to wait for. Yes, the specific one. She's not waiting for all of them, she's waiting for this one. 🎯

🦋 DESCRIPTION 🦋

This function checks if the ACL write or read operation is completed by polling the specified register. That's it, that's the whole thing — it's a polling loop, no interrupts, no fancy async drama, just checking and re-checking until the hardware says "done bestie ✨". It's giving patient, it's giving persistent, it's giving main character energy fr fr.

⭐ RETURN ⭐

  • 0 if the operation is successful 🎉
  • a negative error code if an error occurs 💀

No cap, that's the whole return contract. Check your return value, bestie, don't just ignore it. 🙈

And here's the whole friend group, all of them, every single one, no skips:

tl;dr: you call it, it polls the register, you get 0 or a negative error code. That's the tea. ☕💅
