ENUM KVM_PGTABLE_PROT(9)

📦 version 7.3.1, in nixpkgs unstable

💅 enum kvm_pgtable_prot — the kernel API manual, bestie edition ✨

Okay so you're in the Kernel API Manual and the page is literally called enum kvm_pgtable_prot, and honestly? It's giving permission-slip realness. This is the enum that tells KVM's page-table code what a page is allowed to do and what kind of memory it is. No cap, every bit here matters. 🎀

🌸 NAME 🌸

enum kvm_pgtable_prot — Page-table permissions and attributes. That's it, that's the whole vibe. Permissions AND attributes, bestie, both. 🦋

✨ SYNOPSIS ✨

enum kvm_pgtable_prot {
    KVM_PGTABLE_PROT_PX ,
    KVM_PGTABLE_PROT_UX ,
    KVM_PGTABLE_PROT_X ,
    KVM_PGTABLE_PROT_W ,
    KVM_PGTABLE_PROT_R ,
    KVM_PGTABLE_PROT_DEVICE ,
    KVM_PGTABLE_PROT_NORMAL_NC ,
    KVM_PGTABLE_PROT_SW0 ,
    KVM_PGTABLE_PROT_SW1 ,
    KVM_PGTABLE_PROT_SW2 ,
    KVM_PGTABLE_PROT_SW3

};

Look at that list. Eleven constants. Every single one is a mood, and every single one gets its own moment below. 👑

🧚 Constants 🧚

  • KVM_PGTABLE_PROT_PX — Privileged execute permission. So like, the privileged side can execute. Iconic. 🔥
  • KVM_PGTABLE_PROT_UX — Unprivileged execute permission. Same energy, but for the unprivileged girlies. 💅
  • KVM_PGTABLE_PROT_X — Privileged and unprivileged execute permission. Everybody gets to execute. Generous queen behavior. 👑
  • KVM_PGTABLE_PROT_W — Write permission. Go ahead, write to it, slay. ✍️
  • KVM_PGTABLE_PROT_R — Read permission. The bare minimum, but we respect it. 💖
  • KVM_PGTABLE_PROT_DEVICE — Device attributes. It's giving "this memory is a device, don't treat it like normal RAM." 🫶
  • KVM_PGTABLE_PROT_NORMAL_NC — Normal noncacheable attributes. Normal-ish but noncacheable, which is a whole personality. 🦋
  • KVM_PGTABLE_PROT_SW0 — Software bit 0. Reserved for the software squad, not the hardware. 🎀
  • KVM_PGTABLE_PROT_SW1 — Software bit 1. Second verse, same as the first. ✨
  • KVM_PGTABLE_PROT_SW2 — Software bit 2. Still going. 💜
  • KVM_PGTABLE_PROT_SW3 — Software bit 3. And that's the last software bit, periodt. 🌸
