[PATCH v3] drm/virtio: trace total gem bo for virtio

From: Yiwei Zhang On the success of virtio_gpu_object_create, add size of newly allocated bo to the tracked total_mem. In drm_gem_object_funcs.free, after the gem bo lost its last refcount, subtract the bo size from the tracked total_mem if the original underlying memory allocation is successful

[PATCH v4] drm/virtio: Track total GPU memory for virtio driver

more accurate to do this in device driver layer to best match when the underlying resource gets allocated and destroyed during tracing. Signed-off-by: Yiwei Zhang --- drivers/gpu/drm/virtio/Kconfig | 1 + drivers/gpu/drm/virtio/virtgpu_drv.h| 2 ++ drivers/gpu/drm/virtio/virtgpu_object.c
