PMAP_PAGE_INIT(9)

💖 NAME 💖

okay bestie, listen up — this is pmap_page_init, a lil function from the Kernel Developer's Manual (section 9, the big-kid kernel dev section, iykyk). What does it do? It initializes the machine-dependent fields of a VM page. that's it. that's the whole vibe. 🦋

✨ SYNOPSIS ✨

first, the ritual. you gotta summon the right headers or nothing works, fr fr:

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

void
pmap_page_init(vm_page_t m);

like, <sys/param.h>, <vm/vm.h>, and <vm/pmap.h> — all three, no skipping, no substitutions. the include order is giving main character energy and honestly it ate. 💅

🌸 DESCRIPTION 🌸

so pmap_page_init() does the thing where it initializes the machine-dependent fields of a VM page structure. lowkey important, highkey specific.

and when is it used, you ask? 👀 this procedure is normally used when adding new pages to the VM page queue management lists. that's the moment. that's when it shows up. periodt.

it's not out here initializing everything about a page — just the machine-dependent bits, so don't get it twisted. 🫶
