💖 amdgpu_vm_bo_clear_mappings(9) — Kernel API Manual 💖

okay bestie, welcome to amdgpu_vm_bo_clear_mappings(9) from the Kernel API Manual. This page is giving “remove all mappings in a specific range,” and honestly? iconic. 💅

🌸 NAME 🌸

amdgpu_vm_bo_clear_mappings — remove all mappings in a specific range 🫶

✨ SYNOPSIS ✨

int amdgpu_vm_bo_clear_mappings (struct amdgpu_device *adev , struct amdgpu_vm *vm , uint64_t saddr , uint64_t size );

🎀 ARGUMENTS 🎀

• adev — amdgpu_device pointer. that's the device pointer, periodt. 🫶
• vm — VM structure to use. yes ma'am, the actual VM structure. ✨
• saddr — start of the range. where the range begins, no cap. 💅
• size — size of the range. how big the range is. 🔥

🦋 DESCRIPTION 🦋

Remove all mappings in a range, split them as appropriate. That's the assignment bestie: range in, mappings removed, splitting done as appropriate. Lowkey straightforward, highkey important. 💀

🌈 RETURN 🌈

0 for success, error for failure. So if you get 0, slay; if not, you got an error. 😭
