PMAP_GROWKERNEL(9)

💖 PMAP_GROWKERNEL 💖

okay bestie, welcome to section 9 of the Kernel Developer's Manual — this is pmap_growkernel, and she is the girl for making the kernel's virtual address space bigger. yes, literally. sit down, hydrate, let's go 🫶

✨ NAME ✨

pmap_growkernel — grow the kernel virtual address (KVA) space 🌱

🌸 SYNOPSIS 🌸

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

void
pmap_growkernel(vm_offset_t addr);

like, three whole includes, she's high maintenance but worth it 💅

🦋 DESCRIPTION 🦋

so the pmap_growkernel() function grows the kernel virtual address space all the way up to the virtual address addr. that's it. that's the whole vibe. she's expanding. main character energy fr fr 🌈

and if she needs more page entries to do it? she will allocate more page entries if required. no cap, she just handles it. ✨

not me casually resizing the kernel's address space like it's a group chat 💀
