panthor_vm_create(9)

💖 NAME 💖

okay so bestie, this is panthor_vm_create(9) from the Kernel API Manual — the function that creates a VM, and it's lowkey iconic in the panthor MMU universe. ✨

🌈 SYNOPSIS 🌈

struct panthor_vm * panthor_vm_create (struct panthor_device *ptdev ,
bool for_mcu , u64 kernel_va_start , u64 kernel_va_size , u64
auto_kernel_va_start , u64 auto_kernel_va_size );

🎀 ARGUMENTS 🎀

• ptdev — the device, obvi. 🫶
• for_mcu — True if this is the FW MCU VM. periodt.
• kernel_va_start — start of the range reserved for kernel BO mapping. yes bestie, the start. 💅
• kernel_va_size — size of the range reserved for kernel BO mapping. the range said "respect my size." 🎀
• auto_kernel_va_start — start of the auto-VA kernel range. slay. ✨
• auto_kernel_va_size — size of the auto-VA kernel range. it's giving range energy. 🌸

🦋 RETURN 🦋

A valid pointer on success, an ERR_PTR otherwise. no cap — that's literally the whole return vibe. 😭
