Get GCE HW thread execute count from the GCE HW register. 2. Add 1 to the execute count and then store into a shared memory. 3. Set a software event siganl as secure irq to GCE HW. Since the value of execute count + 1 is stored in a shared memory, CMDQ driver in the normal world can use it to handle task done in irq handler and CMDQ driver in the secure world will use it to schedule the task slot for each secure thread.
