📦 version 7.3.1, in nixpkgs unstable

💖 kvm_pgtable_hyp_init(9) — like, the hypervisor stage-1 page-table glow-up 💖

Okay bestie, welcome to the Kernel API Manual ✨ — this is kvm_pgtable_hyp_init(9) and she is the moment your hypervisor stage-1 page-table gets born. Think of it as the birth announcement, but for page tables. Iconic.

🌸 NAME 🌸

kvm_pgtable_hyp_init — initialises a hypervisor stage-1 page-table. That's it, that's the whole personality. 🎀

✨ SYNOPSIS ✨

int kvm_pgtable_hyp_init (struct kvm_pgtable *pgt , u32 va_bits , struct
kvm_pgtable_mm_ops *mm_ops );

Yes the spacing is like that. We don't fix it, we respect it. 💅

🦋 ARGUMENTS 🦋

  • pgt — the uninitialised page-table structure you're about to bring to life. She starts empty, bestie, and it's your job to initialise her. Main character energy fr fr.
  • va_bits — maximum virtual address bits. That's the ceiling, the limit, the "how much address space are we working with" number. 🫶
  • mm_ops — memory management callbacks. The little crew of functions that handles the memory stuff for you. No cap, you gotta supply them.

🔥 RETURN 🔥

  • 0 on success 🎉 — everything slayed, page-table initialised.
  • A negative error code on failure 😭 — something went sideways, check the code.

👑 SEE ALSO 👑

The whole extended friend group 🫶 — all these live in the kernel file ./arch/arm64/include/asm/kvm_pgtable.h:

That's thirty entries. We listed all thirty. Obsessed with our consistency. 💀✨

🌈 Quick vibe check: pgt has to be uninitialised when you hand it over — this function does the initialising. Don't double-init, bestie, that's not the move. 🙈

And that's the whole page, bestie — brought to you by ./arch/arm64/include/asm 🧚, dated October 2026 ⭐, and signed off by kvm_pgtable_hyp_init(9) herself 💜. Go initialise something beautiful. Periodt. 💅🎀
