Backport Argus library files from JP 5.1.4 to 5.1.2

Robotics & Edge Computing Jetson & Embedded Systems Jetson Xavier NX
1

It would be great if this topic would be merged with the original one, now locked: Jetson NX high CPU syscall usage on nvargus kernel 4.9 vs 5.10

Wanted to test the fix for Argus 40% CPU reduction mentioned in the Release Notes for JP 5.1.4, but since we are locked on a custom kernel, we can’t upgrade the whole system right now, so the question is: what files contain the fix, so we can copy them from a new install?

Thank you!

Replace the libs for CPU usage of Argus.

libnvscf.so.35.4.1.cpu_usage (8.4 MB)

Thanks

please note that,
we have seen 40% CPU reduction during 12 camera use case, which does not always translate to 40% aggregate reduction with 2 or 4 camera use cases.

I have replaced the file attached by you into this path: /usr/lib/aarch64-linux-gnu/tegra/libnvscf.so

Notice the “tegra” different from “nvidia” in the path.

Unfortunately, there is no measurable impact on the CPU load 🙁 more than half of the CPU time is sys calls, this was not the case in JP 4.6, see the linked topic.

PS: this is for 2 cameras.
