pvr_vm_unmap(9)

hii bestie 💖 welcome to pvr_vm_unmap(9) from the Kernel API Manual — okay so this is the page for unmapping a section of device-virtual memory that’s already mapped. it’s giving “that mapping had its moment, now it’s exiting stage left” energy ✨

💅 NAME

pvr_vm_unmap — unmap an already mapped section of device-virtual memory. lowkey the cleanup icon, no cap 💅

✨ SYNOPSIS ✨

int pvr_vm_unmap (struct pvr_vm_context *vm_ctx , u64 device_addr , u64 size );

🎀 ARGUMENTS 🎀

• vm_ctx — target VM context. the VM context we’re working in, bestie 🫶
• device_addr — virtual device address at the start of the target mapping. that’s the starting point of the target section, periodt ✨
• size — size of the target mapping. how big the mapping is, fr fr 🎀

🌈 RETURN 🌈

vibe check on the return values:

• 0 on success — slay, we love a clean win 💖
• Any error encountered by drm_gpuva_find — if that call runs into an error, it comes through here, no cap 🙈
• Any error encountered by pvr_vm_unmap_obj_locked — and any error from this call comes through too 💅
