VM_MAP_INIT(9)

✨ VM_MAP_INIT ✨

okay bestie, gather round, because we're talking about vm_map_init from the Kernel Developer's Manual — section 9, the deep-magic zone 💅

🌸 NAME 🌸

vm_map_init — initialize a vm_map structure for process zero 👑

🦋 SYNOPSIS 🦋

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

void
vm_map_init(vm_map_t map, vm_offset_t min, vm_offset_t max);

like, three includes, one function, zero drama. iconic behavior honestly 🎀

💖 DESCRIPTION 💖

so the vm_map_init() function does the absolute most important little job ever: it initializes the system map map by setting its upper and lower address bounds to max and min respectively. upper goes to max, lower goes to min — yes the order flips, no it's not a typo, that's just how she is 🫶

and it doesn't stop there! it also initializes the system map mutex 🔥 because a map without a mutex is giving chaos energy and we simply cannot.

🧚 IMPLEMENTATION NOTES 🧚

no cap: this routine is for internal use only. it's called during early system initialization, so like, it's backstage crew, not main character. don't come for her unless you're literally booting the system 💀
