Profiling

Performance metrics for nvsipl_camera can be displayed by specifying the --profile switch. The nvsipl_camera --profile command line option takes a file prefix as an argument and dumps the profiling timestamps into file-prefix_cam_x_out_y.csv for each camera and enabled output. The dumped CSV file has the following columns:

For Capture Output

Capture Timestamp (us)

For ISP Output

Capture Timestamp (us), Capture Done Event Timestamp (us)

Following is an example showing how to use this feature:

$ ./nvsipl_camera --platform-config "SF3324_DPHY_x4" --link-enable-masks "0x0001 0x0000 0x0000 0x0000" -d 0 --profile /tmp/sipl_profile
