On the hikey960 platform, only one domain is supported, and you can see that the media business is all used by the domain created by the ion. After adding IPU (AI) to Hikey970 platform, it uses its own domain, so the underlying layer needs to support multiple page mapping of domain, otherwise IPU and DRM mapping will conflict, resulting in IPU recognition of image failure.
