panthor_vm_pool_destroy_vm(9)

🌸 NAME 🌸

okay so this is panthor_vm_pool_destroy_vm(9) from the Kernel API Manual — and it's literally here to Destroy a VM 💀✨

✨ SYNOPSIS ✨

int panthor_vm_pool_destroy_vm (struct panthor_vm_pool *pool , u32
       handle );

🎀 ARGUMENTS 🎀

• pool — the VM pool, bestie 🫶
• handle — the VM handle 🎀

💅 DESCRIPTION 💅

okay so listen: this function doesn't free the VM object or its resources. not even a little. what it does do is kill all mappings and make sure nothing can be mapped after that point. periodt 💅

if there was any active jobs at the time this function is called, these jobs should experience page faults and be killed as a result 😭💀

the VM resources are freed when the last reference on the VM object is dropped. that's the rule, no cap 🫶

💖 RETURN 💖

0 for success, negative errno value for failure ✨
