xe_memirq_hwe_handler(9)

✨ NAME ✨

xe_memirq_hwe_handler — bestie, this is the one that checks on a specific HW engine's interrupts and processes them 💅

Like, it's a Kernel API Manual situation, and this function is literally the vibe check for one engine's interrupt traffic.

---

🎀 SYNOPSIS 🎀

void xe_memirq_hwe_handler (struct xe_memirq *memirq , struct xe_hw_engine *hwe );

Two args, no return value, in and out, periodt. 🫶

---

🌸 ARGUMENTS 🌸

• memirq — the xe_memirq. That's the memory-based-interrupt situation our girl is working with. 🧚
• hwe — the hw engine to process. Yes, the hw engine — the one getting its interrupts handled. ✨

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this function reads and dispatches Memory Based Interrupts for the HW engine you handed it. That's it, that's the whole job, and it ate. 🔥

You pass in the memirq and the hwe, and it goes and deals with the interrupts for that specific engine. No cap, that's the entire plot. 💀
