PMAP_MINCORE(9)

✨ NAME ✨

okay so bestie, this is pmap_mincore, and we're lowkey in the Kernel Developer's Manual — the header energy is PMAP_MINCORE(9), but we're folding that in here instead of copying the line, periodt 💅. The whole vibe? It determines if a virtual address is resident in physical memory. No cap. 🫶

🌸 SYNOPSIS 🌸

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

int
pmap_mincore(pmap_t pmap, vm_offset_t addr);

🦋 DESCRIPTION 🦋

The pmap_mincore() function is the main character here: it determines if the page at the virtual address addr in the physical map pmap is resident in physical memory. Literally that's the whole quest. ✨

It is the machine-dependent interface used by the mincore(2) system call. iykyk 🧚

🎀 RETURN VALUES 🎀

If the page is resident in physical memory, a mask of flags is returned, and the meaning of those flags is documented in mincore(2). Otherwise, 0 is returned. Slay. 💖

The pmap must exist and addr must be mapped into the pmap. If any error occurs, the machine-dependent implementation should return 0. Not me stressing the should — it's right there in the source, bestie. 😭
