For the Secure Video Path (SVP) feature, inculding the memory stored secure video content, the registers of display HW pipeline and the HW configure operations are required to execute in the secure world. So using a CMDQ secure driver to make all display HW registers configuration secure DRAM access permision settings execute by GCE secure thread in the secure world. We are landing this feature on mt8188 and mt8195 currently.
