Just upgraded Jetson Nano 2gb to the new JetPack 4.5 release. We are running without the lightdm or other display manager. A “top” with none of our programs running, the top process is “irq/74-tegradc.” What is that interrupt and what is it doing?
The software we are developing is using OpenCV to run several detectors on an input video stream. Two of the detectors run on the graphics processor using CUDA. The Nano 4gb version running the same program is very responsive to terminal commands. The Nano 2gb terminal is totally unresponsive running the same program. The nvzram had to be disabled to get the programs to run and only the 4gb swapfile is being used. Is that irq/74-tegradc process aggravating the memory swap and terminal response issues.
