From: Philip Yang Date: Thu, 26 Jan 2023 23:50:09 +0000 (-0500) Subject: drm/amdkfd: Alloc memory of GPU support memory partition X-Git-Tag: v6.6.7~2401^2~12^2~320 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=53c5692e7a3c8e8eed3ec6b876a3c982d217a5d7;p=platform%2Fkernel%2Flinux-starfive.git drm/amdkfd: Alloc memory of GPU support memory partition For dGPU mode VRAM allocation, create amdgpu_bo from amdgpu_vm->mem_id, to alloc from the correct memory range. For APU mode VRAM allocation, set alloc domain to GTT, and set bp->mem_id_plus1 from amdgpu_vm->mem_id + 1 to create amdgpu_bo, to allocate system memory from correct NUMA node. For GTT allocation, use mem_id -1 to allocate system memory from any NUMA nodes. Remove amdgpu_ttm_tt_set_mem_pool, to avoid the confusion that memory maybe allocated from different mem_id.
