💖 pkvm_alloc_private_va_range(9) 💖

okay so real talk, bestie: this is a page from the Kernel API Manual, and it's giving “small function, very specific job” energy. Let's get into it ✨

🌸 NAME 🌸

pkvm_alloc_private_va_range — Allocates a private VA range.

🦋 SYNOPSIS 🦋

int pkvm_alloc_private_va_range (size_t size , unsigned long *haddr );

🎀 ARGUMENTS 🎀

• size — The size of the VA range to reserve. literally the amount of virtual address space we're asking for 💅
• haddr — The hypervisor virtual start address of the allocation. this is where the starting address gets handed back to you 🫶

✨ DESCRIPTION ✨

The private virtual address (VA) range is allocated above __io_map_next and aligned based on the order of size. that's the whole vibe: it sits above __io_map_next, and the alignment is determined by the order of size — no cap, that's the rule 🔥

💜 RETURN 💜

0 on success or negative error code on failure. so like, zero means slay, negative means something went wrong 😭
