Is GPU L1 cache enable in Jetson x1?

I am running a code in Jetson X1. When i compile my code with the flag -Xptxas -dlcm=ca (enable L1 cache), the execution time of my application is the same as if i compile it with the flag -Xptxas -dlcm=cg (disabled L1 cache). In addition, when i profile my application with nvvp there are not metrics for L1 cache to profile. Is L1 cache enable in Jetson x1?
Thank you in advance!
