💖 PMAP_RELEASE(9) — release resources held by a physical map 💖

okay so this is the PMAP_RELEASE(9) page from the Kernel Developer's Manual, and bestie, it's giving “small but important kernel cleanup energy.” let's get into it 🫶

🌸 NAME

• pmap_release — release resources held by a physical map

---

✨ SYNOPSIS

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

void
pmap_release(pmap_t pmap);

---

🎀 DESCRIPTION

The pmap_release() function releases any resources held by the physical map pmap. This function is called when a pmap initialized by the corresponding function, pmap_pinit(), is being released. literally a little handoff moment 💅

---

🧚 IMPLEMENTATION NOTES

This function should only be called if pmap no longer contains any valid mappings.

fr fr, that's the vibe check: pmap has to be done with its valid mappings before you call this. no cap 🚫
