jean=Philippe, The driver just dump the statistics as read from the hardware. The VPFE Programmers Reference Guide (PRG) explains how the information is packed in memory.I am not sure if a customer needs to sign any NDA to get the details. Please check with TI support channel if that is the case.
The driver works in the following way. Application sets configuration about number of paxels/windows etc in the driver after opening the aew device and start capture in VPFE. Application then issues a read call to the device for statistics. The isr kicks in when statistics is available. The application read call will get unblocked when isr happens and the data is copied to user space. The Application needs to process the raw data using the packing information specified in the PRG.
