Re: [PATCH v2 1/1] drm/amdkfd: use allowed domain for vmbo validation

[Christian König]

Am 08.06.21 um 13:27 schrieb Nirmoy Das:
Fixes handling when page tables are in system memory.

v2: remove unwanted variable.
     change amdgpu_amdkfd_validate instead of amdgpu_amdkfd_bo_validate.

The structure define of amdgpu_vm_parser isn't used any more if we drop 
this as well, isn't it?
