💅 xe_ggtt_map_bo_unlocked(9) 💅

okay so this is a page straight out of the Kernel API Manual, bestie — welcome to the group chat 🫶

✨ NAME ✨

xe_ggtt_map_bo_unlocked — the girl whose whole job is restoring a mapping of a BO into GGTT 💖

---

🎀 SYNOPSIS 🎀

void xe_ggtt_map_bo_unlocked (struct xe_ggtt *ggtt , struct xe_bo *bo );

like… she takes two things and returns nothing (void), she's got main character energy but zero receipts 😭

---

🌸 ARGUMENTS 🌸

• ggtt — the xe_ggtt where the node will be mapped. that's her venue, her stage, her whole vibe check 🎤
• bo — the xe_bo to be mapped. the guest of honor fr fr 👑

---

🦋 DESCRIPTION 🦋

okay so listen: this one is used to restore a GGTT mapping after suspend. that's it. that's the whole plot. she wakes up from the nap and puts the mapping back where it belongs, no cap ✨😴➡️💅
