In ARC++, the wayland sevice and the video stack rely on GRALLOC_DRM_GET_STRIDE and (*lock_ycbcr) with zero flags to return the metadata associated with the buffer. In the past, we've simply returned the metadata that was calculated during allocation. Since the current virtio-gpu API relies on shadow buffers, there's actually two different sets of metadata: 1) The metadata of the shadow buffer --> useful for mapping 2) The metadata of the host resource --> useful for passing to Chrome For the wayland_service and video stack, we want to return (2). For the Android framework, we want to return (1).
