As far as I can see the problem is not inside amdg= pu, > but rather inside the driver which is importing buffers from amdgpu. At least, we should call drm_prime_gem_destroy() to detach dma-buf(if exist= s) before WARN_ON_ONCE(bo->pin_count). And do you think if clients don't unmap/detach amdgpu dma-buf properly, sho= uld amdgpu do that work? Thanks! --=20 You may reply to this email to add a comment.
