How to measure the bandwidth of memory?

According to the link below

https://devtalk.nvidia.com/default/topic/1047012/jetson-agx-xavier/how-to-measure-l3-cache-miss-by-using-uncore-pmu-on-nvidia-jetson-agx-xavier/

there was no software support to get the L3 Cache event and it is said that the feature is under development. I just would like to know when the feature will be supported?

If that feature cannot be supported in the near future, are there any suggestions to get the measurement of memory bandwidth? (If the measurement can be shown in the NVIDIA System Profiler, that will be better.)

Thank you.

Hi jiaqi.zuo,

We’ve investigated this feature, but some dependencies while implementing it, these is no clear timeline and schedule yet. Once it’s clear, I will share with you.

Thanks

Thank you for your reply.
