[PATCH 1/7] drm/amdgpu: cleanup adjust_mc_addr handling v2
Christian König
deathsimple at vodafone.de
Wed May 17 09:22:46 UTC 2017
From: Christian König <christian.koenig at amd.com>
Rename adjust_mc_addr to get_vm_pde and check the address bits in one place.
v2: handle vcn as well, keep setting the valid bit manually,
add a BUG_ON() for GMC v6, v7 and v8 as well.
