TDA4VM: GPU tiler and renderer works sequentially in OpenVX Node

HI,

I saw Grigory's questions and TI expert's answers.

In the latest PSDK, 7.3 for TDA4, there is no such functionality and in SRV test sample there is explicit glFinish() which affects PVR GPU performance (tiler and renderer works only sequentially without overlapping in pipeline for two subsequent output framebuffers.

I tested with PVRTune. 

In case of Linux only, tiler and renderer works in parallel.

But in case of RTOS + Linux, tiler and renderer works sequencially.

Are there any design guides or sample on how to implement similar asynchronous pipeline?

Best regards

Jack
