xe_memirq_handler(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're fancy here 💅 — and today's main character is:

xe_memirq_handler — the Memory Based Interrupts_ Handler. that's it. that's the whole vibe. it handles the memory-based interrupts. iconic behavior only ✨

---

🌸 SYNOPSIS 🌸

void xe_memirq_handler (struct xe_memirq *memirq );

look at that signature. so clean. so symmetrical. she ate 🎀

---

🦋 ARGUMENTS 🦋

• memirq — the xe_memirq. that's the whole description. the xe_memirq. literally just the xe_memirq. no notes, she speaks for herself 💜

---

✨ DESCRIPTION ✨

so what does she actually do? glad you asked 🫶

this function reads the Memory Based Interrupts and dispatches them. read 'em, dispatch 'em, that's the entire job description. lowkey the most efficient little function ever — no cap, she's got one task and she's slaying it 💅🔥

ngl this page is short and that's on purpose — she does one thing and does it well. go read the SEE ALSOs if you want the full lore 🧚

okay that's the whole page!! this one came out of ./drivers/gpu/drm/xe, and it's dated October 2026 — the version tag on the bottom is xe_memirq_handler(9) itself, so like, she signed her own name at the bottom. self-referential queen 👑💖 mwah, bye bestie!! 💕
