Hi, Borislav and ARM folks.

Thank you for the information. We would like to see how cpu<NUM>/cache is implemented on x86 first, since we are not familiar with the design of cpu<num>/cache.

We agree that it is better to place hardware prefetch files under the cpu<num>/cache directory.

To the ARM folks: Would you give me information about the current state of cpu<num>/cache implementation in ARM and the future plans? If it doesn't yet exist as a feature, we would like to contribute to the work to enable it.
