🌸 NAME 🌸

pmap_pinit, pmap_pinit0 — initialize pmap structures 💖

---

✨ SYNOPSIS ✨

like, you gotta include these first, obvi:

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

void
pmap_pinit(pmap_t pmap);

void
pmap_pinit0(pmap_t pm);

---

🦋 DESCRIPTION 🦋

okay so <pink>pmap_pinit()</pink> is the main character here — it initializes the preallocated and zeroed structure pmap, like the one you'd find in a vmspace structure. it's giving "prep the vibe before the party starts" ✨

then there's <purple>pmap_pinit0()</purple>, which initializes the physical map pm — and this one is literally associated with process 0, aka the very first process created in the system 👑 first one ever, iykyk.
