drm_gpuvm_exec_lock_range(9)

✨ drm_gpuvm_exec_lock_range ✨

okay so bestie, this is the drm_gpuvm_exec_lock_range page from the Kernel API Manual 💅 it's literally about prepping all your BOs in a range, no cap

SYNOPSIS

int drm_gpuvm_exec_lock_range (struct drm_gpuvm_exec *vm_exec , u64 addr , u64 range );

ARGUMENTS

• vm_exec — the drm_gpuvm_exec wrapper, it's giving main character energy for the whole operation 🎀
• addr — the start address within the VA space, like where the vibe check begins ⭐
• range — the range to iterate within the VA space, so how far we're going, periodt 🌸

DESCRIPTION

Acquires all dma-resv locks of all drm_gem_objects mapped between addr and addr + range. literally locking it all down bestie 🔥

RETURN

0 on success, negative error code on failure. slay when it works, 😭 when it doesn't
