From f24e924b7e8aba7b62671e7e1a19d83301a08597 Mon Sep 17 00:00:00 2001 From: Philip Yang Date: Thu, 26 Jan 2023 18:25:28 -0500 Subject: drm/amdgpu: Add memory partition mem_id to amdgpu_bo Add mem_id_plus1 parameter to amdgpu_gem_object_create and pass it to amdgpu_bo_create. For dGPU mode allocation, mem_id is used by VRAM manager to get the memory partition fpfn, lpfn from xcp manager. For APU native mode allocation, mem_id is used to get NUMA node id from xcp manager, then pass to TTM as numa pool id to alloc memory from the specific NUMA node. mem_id -1 means for entire VRAM or any NUMA nodes.
