From fcfefd85f18a0004c7c7b499f0701fd2c76d4c68 Mon Sep 17 00:00:00 2001 From: Rajneesh Bhardwaj Date: Mon, 27 Feb 2023 20:08:29 -0500 Subject: drm/amdkfd: Native mode memory partition support For native mode, after amdgpu_bo is created on CPU domain, then call amdgpu_ttm_tt_set_mem_pool to select the TTM pool using bo->mem_id. ttm_bo_validate will allocate the memory to the correct memory partition before mapping to GPUs.
