PMAP_PROTECT(9)

💖 PMAP_PROTECT 💖

okay bestie, sit down, hydrate, and let me tell you about pmap_protect(9) — she's a Kernel Developer's Manual girlie, section 9, and she does exactly one thing and she does it flawlessly. ✨

🌸 NAME 🌸

pmap_protect — set physical page protection 💅

like. the name is the plot. she sets the protection. that's the whole vibe. no cap.

🦋 SYNOPSIS 🦋

#include <sys/param.h>
#include <vm/vm.h>
#include <vm/pmap.h>

void
pmap_protect(pmap_t pmap, vm_offset_t sva, vm_offset_t eva,
    vm_prot_t prot);

yes you need all three includes, don't try to be cute and skip one, she will Not compile for you 🙈

🎀 DESCRIPTION 🎀

so the tea is this: the pmap_protect() function sets the physical page permissions to prot for all the physical pages in the physical map pmap, in the virtual address range between sva and eva. 💖

that's it. that's her whole job. range in, permissions out, main character energy only. ✨
