Or SW driver use CPU to write a event id to GCE register to trigger the GCE event corresponding to that event id. - The HW event means: a GCE event signal triggered by HW engines. e.g. When HW OVL fetches all the data in frame buffer, HW OVL will send a frame done irq and also send a frame done GCE event via HW bus directly. CMDQ_SYNC_TOKEN_SECURE_THR_EOF is a SW token event that is set in the end of each cmdq secure pkt. It is used as a secure irq to notify CMDQ driver in the normal world that GCE secure thread has completed a secure cmd buffer in thee secure world.
