Originally, only the PTE valid is taken in consider.
The PRT case is missied when bo update which raise problem.
We need add condition for PRT case.
v2: add PRT condition for amdgpu_vm_bo_update_mapping, too
Good point, yes. Feel free to commit it like this, but we might want to
add a define for (AMDGPU_PTE_VALID | AMDGPU_PTE_PRT) at some time to
make the code easier to read.
Going to take care of this as a follow up cleanup as soon as the patch
lands on amd-staging-drm-next.
Regards,
Christian.
v3: fix one typo error
