kvm_pgd_init(9)

💫 kvm_pgd_init(9) 💫

okay so this is a page from the Kernel API Manual, and honestly? she's short, she's sweet, and she's doing exactly one (1) job. let's get into it 🎀

---

🌸 NAME 🌸

kvm_pgd_init — initialise the KVM GPA page directory, bestie. that's it, that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

void kvm_pgd_init (void *page );

---

💜 ARGUMENTS 💜

• page — a pointer to the page directory (PGD) for the KVM GPA. like, hand her the PGD and she'll take it from there 🫶

---

🔥 DESCRIPTION 🔥

So what she actually does: kvm_pgd_init initialises a KVM GPA page directory and fills it with pointers to the invalid table — meaning it represents no mappings at all. empty. blank slate. main character energy before anything happens 💅

It's similar to pgd_init, however (and this is the important part, don't skip it 🙈) it initialises all the page directory pointers, not just the ones corresponding to the userland address space. Why? because this is for the guest physical address space rather than a virtual address space. iykyk ✨
