💅 xe_default_l...with_address(9) — Kernel API Manual ✨

okay so bestie, the manual name got literally chopped in half by the title bar (it's giving tragic), but the full name is xe_default_lrc_update_memirq_regs_with_address and this whole page is about that. it's a Kernel API Manual situation, we're in the (9) section, it's very kernel-core. let's go 🎀

🌸 NAME 🌸

xe_default_lrc_update_memirq_regs_with_address — Re-compute GGTT references in default LRC of given engine. 🦋

that's it. that's the whole vibe. it recomputes GGTT references, in the default LRC, of whatever engine you hand it. no cap, that's the job.

---

✨ SYNOPSIS ✨

void xe_default_lrc_update_memirq_regs_with_address (struct xe_hw_engine
*hwe );

note the void bestie — it returns nothing, it just does the thing and dips 💅

---

💖 ARGUMENTS 💖

• hwe — the xe_hw_engine struct instance. that's the one (1) thing you gotta give it. the engine. the whole engine. 🫶

🔥 SEE ALSO 🔥

okay so there is a lot of family here, this function has main character energy and knows everyone. also heads up, the kernel file lives at ./drivers/gpu/drm/xe/xe_lrc.c — that's where the lore is 👑
