[riscv-CMOs:master] New Comment on Issue #48 How to discover the information of cache block size by software?
By cmuellner:

We were discussing that as part of the kernel support for CBO. It was agreed to provide this information via DTB as specified here: http://lists.infradead.org/pipermail/linux-riscv/2022-May/014886.html

The interface for userspace is still not defined.

Also, note that the CBO granularity does not necessarily need to be equal to the cache line size.
