xe_ggtt_node_remove(9)

💅 xe_ggtt_node_remove(9) — the kernel API manual, bestie edition

Okay so welcome to xe_ggtt_node_remove, straight out of the kernel API manual (that's the <9> section, iykyk) ✨ Pull up a chair, because this one is short but it matters.

---

✨ NAME ✨

xe_ggtt_node_remove — Remove a &xe_ggtt_node from the GGTT 🫶

Like, that's the whole vibe. A node goes in, a node comes out. The GGTT said "not today, bestie" and the node is removed.

---

🌸 SYNOPSIS 🌸

void xe_ggtt_node_remove (struct xe_ggtt_node *node , bool invalidate );

Look at her. void return, two args, no notes. Iconic behavior honestly 👑

---

🎀 ARGUMENTS 🎀

• node — the xe_ggtt_node to be removed 💀 Like, the actual node. The one getting yeeted. That's the main character of this whole operation.
• invalidate — if node needs invalidation upon removal 🔥 So this one's a bool, and it's your call: does this node need to be invalidated when it gets removed? Set it accordingly. No cap.

Fr fr, these are the only two things you pass in, so don't overthink it. Just know what your node needs before you send it off into the void 🙈
