[PATCH 056/459] drm/amdgpu: add gmc v10 ip block for navi10 (v6)
Alex Deucher
alexdeucher at gmail.com
Mon Jun 17 19:10:17 UTC 2019
From: Hawking Zhang <Hawking.Zhang at amd.com>
GMC in the GPU memory controller.
v1: add place holder and initial basic implementation (Ray)
v2: retire unused amdgpu_gart_set_defaults (Hawking)
v3: re-work get_vm_pde function (Hawking)
v4: replace legacy amdgpu_vram/gtt_location with
amdgpu_gmc_vram/gtt_location (Hawking)
v5: squash in updates (Alex)
v6: use get_vbios_fb_size (Alex)
