💅 ks8851_rxctrl_work(9) — the glow-up

Okay so bestie, welcome to the man page for ks8851_rxctrl_work from the Kernel API Manual. This is literally the work handler that changes the rx mode and it's giving very important background-task energy. No cap, let's get into it. ✨

🌸 SYNOPSIS 🌸

void ks8851_rxctrl_work (struct work_struct *work );

---

🎀 ARGUMENTS 🎀

• work — the work structure this belongs to. That's it, that's the whole argument. She's simple, she's iconic. 🫶

💖 DESCRIPTION 💖

So here's the vibe: this function locks the device and issues all the necessary changes to the receive mode from the network device layer. Why do it this way? Because we need to do this without having to sleep whilst holding the network device lock. Basically the network device lock is main character and we're not about to make it wait around while we nap. 😴🚫

Now for the technical tea ☕: the recommendation from Micrel is that the RXQ is shutdown whilst the receive parameters are programmed. So what happens is we issue a write to disable the RXQ, and then we wait for the interrupt handler to be triggered once the RXQ shutdown is complete. After that, the interrupt handler writes the new values into the chip. It's a whole relay race and honestly? Slay. 🏁✨
