drm/amdgpu: Set vmbo destroy after pt bo is created
Under VRAM usage pression, map to GPU may fail to create pt bo and vmbo->shadow_list is not initialized, then ttm_bo_release calling amdgpu_bo_vm_destroy to access vmbo->shadow_list generates below dmesg and NULL pointer access backtrace: Set vmbo destroy callback to amdgpu_bo_vm_destroy only after creating pt bo successfully, otherwise use default callback amdgpu_bo_destroy. amdgpu: amdgpu_vm_bo_update failed amdgpu: update_gpuvm_pte() failed amdgpu: Failed to map bo to gpuvm amdgpu 0000:43:00.0: amdgpu: Failed to map peer:0000:43:00.0 mem_domain:2 BUG: kernel NULL pointer dereference, address: RIP: 0010:amdgpu_bo_vm_destroy+0x4d/0x80 [amdgpu] Call Trace: <TASK> ttm_bo_release+0x207/0x320 [amdttm] amdttm_bo_init_reserved+0x1d6/0x210 [amdttm] amdgpu_bo_create+0x1ba/0x520 [amdgpu] amdgpu_bo_create_vm+0x3a/0x80 [amdgpu] amdgpu_vm_pt_create+0xde/0x270 [amdgpu] amdgpu_vm_ptes_update+0x63b/0x710 [amdgpu] amdgpu_vm_update_range+0x2e7/0x6e0 [amdgpu] amdgpu_vm_bo_update+0x2bd/0x600 [amdgpu] update_gpuvm_pte+0x160/0x420 [amdgpu] amdgpu_amdkfd_gpuvm_map_memory_to_gpu+0x313/0x1130 [amdgpu] kfd_ioctl_map_memory_to_gpu+0x115/0x390 [amdgpu] kfd_ioctl+0x24a/0x5b0 [amdgpu] Signed-off-by: Philip Yang <Philip.Yang@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
