In svp mode, optee driver would wait the irq, but why optee driver does not notify normal world driver? The normal world driver here does not wait anything and keep going, so it would get the frame
which has not been processed done and pass it to next module such as mdp? The normal world driver does not wait here, how does it make sure the frame is processed done?

Normal and secure world can receive the interrupt at the same time when
play secure video.
The driver process the interrupt and clean the interrupt in optee-os
when play secure video, not normal world. So the driver needn't to wait
interrupt and clean the interrupt in normal world
