va_range_fini(9)

💖 NAME 💖

Okay so bestie, you're on the va_range_fini(9) page in the Kernel API Manual, and honestly? It's a little cleanup baddie.

va_range_fini — clear a virtual addresses range. That's the whole assignment. She tidies up, she leaves. Periodt. 💅

---

✨ SYNOPSIS ✨

void va_range_fini (struct hl_device *hdev , struct hl_va_range
*va_range );

Not her returning anything btw — she's a void girlie, she does the work and dips. 🫶

---

🎀 ARGUMENTS 🎀

• hdev — pointer to the habanalabs structure. Your main-character handle to the whole device thing.
• va_range — pointer to virtual addresses range. The range in question, the one getting the glow-down.

---

🌈 DESCRIPTION 🌈

This function does the following, and it's lowkey just the one thing:

• Frees the virtual addresses block list and its lock. That's it. Block list: gone. Lock: also gone. No loose ends, no leftovers, no "wait did we free that" at 3am. 🔥

Ok that's the page!! She's short, she's efficient, she's iconic. Go free that block list, bestie. 🧚✨

And a lil sign-off for the credits stans: this whole thing lives in ./drivers/accel/habanalabs/common, it's dated October 2026, and it shipped in the Kernel API Manual. Mwah. 💜🍓
