vbg_guest_mappings_init(9)

🦋 vbg_guest_mappings_init 🦋

okay bestie, welcome to the Kernel API Manual entry for vbg_guest_mappings_init(9) — the little function that handles some truly main-character memory-reservation business. 💖

---

🎀 NAME 🎀

• vbg_guest_mappings_init — reserves memory in which the VMM can relocate any guest mappings that are floating around. slay. ✨

---

🌸 SYNOPSIS 🌸

void vbg_guest_mappings_init (struct vbg_dev *gdev );

---

🧚 ARGUMENTS 🧚

• gdev — the Guest extension device. that's the whole vibe check, bestie. 🫶

---

💅 DESCRIPTION 💅

okay so this operation is a little bit tricky 😭 — the VMM might not accept just any address because of address clashes between the three contexts it operates in, so we try several times. no cap, it's giving complicated-address-drama, but we keep trying. 🔥

Failure to reserve the guest mappings is ignored. literally ignored, bestie. 💀
