PMAP_ACTIVATE(9)

💖 PMAP_ACTIVATE — activate a physical map 💖

okay bestie, so this is the pmap_activate page from section 9 of the Kernel Developer's Manual (that's the kernel-dev girlies section, iykyk 🧚). It's a tiny page, but it's so important, no cap.

✨ NAME ✨

pmap_activate — activate a physical map 🗺️✨

🌸 SYNOPSIS 🌸

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

void
pmap_activate(struct thread *td);

like, include all three headers or it literally will not work, periodt 💅

🦋 DESCRIPTION 🦋

The pmap_activate() function activates the physical map for a user thread td. 🌈

⚠️ bestie listen — this function must be called before the thread's address space may be accessed. Not after. Not "eh, whenever". BEFORE. The way that the address space is just sitting there un-accessible until you do this… 😭
