Using L1 Cache on Jetson Nano

Hi all,

How do I enable the use L1 cache on the Maxwell based GPU (which Jetson Nano has).
I read that in Maxwell the Texture cache and L1 cache are unified.


I tried

nvcc -Xptxas -dlcm=ca

But it did not show any change in performance…

I don’t think the Maxwell arch are the same with Nano.

Hi,

For Nano, which GPU architecture is 5.3, please not all the memory type are supported L1 cache.
You can find same memory cache information in the below document:

Thanks.
