Interrupt Latency of Jetson Xavier NX/AGX?


Is there any documentation describing the interrupt latency of the Jetson Xavier NX or Jetson AGX Xavier?

Online I have seen limited/generalized details, but would prefer to have these numbers confirmed for the NX and AGX:

“worst-case of less than 40 microseconds in the presence of a non-CUDA stress-intensive load” and
“average interrupt response time on a real-time shielded core is consistently ~8 microseconds regardless of load.”

Thank you.

Just check looks like don’t have this kind documentation.


Can Nvidia perform some internal testing on interrupt latency and provide results to its customers?
