[PATCH 4/6] drm/amd: Interface change to support 64 bit page_table_base
Felix Kuehling
Felix.Kuehling at amd.com
Thu Sep 13 01:44:05 UTC 2018
From: Shaoyun Liu <Shaoyun.Liu at amd.com>
amdgpu_gpuvm_get_process_page_dir should return the page table address
in the format expected by the pm4_map_process packet for all ASIC
generations.
