ps3_mm_region_create(9)

🌸 NAME 🌸

ps3_mm_region_create — bestie, this one creates a memory region in the vas ✨ (yes, that's the whole vibe, and it's from the Kernel API Manual, iykyk).

🦋 SYNOPSIS 🦋

int ps3_mm_region_create (struct mem_region *r , unsigned long size );

💅 ARGUMENTS 💅

• r — a pointer to a struct mem_region that's gonna receive the initialized values 🫶
• size — the region size you're requesting, no cap

🎀 DESCRIPTION 🎀

Okay so this implementation creates the region with the vas large page size. Literally iconic.

size is rounded down to a multiple of the vas large page size — so don't come for this function expecting it to round up, because it will not 💀.
