Are page walks required to snoop the D-cache?
It is indeed valid for the page-table walker not to observe stores that have occurred since the last SFENCE.VMA instruction. That thread is 4.5 years old, and the RISC-V Linux kernel port has changed

Draft writeup of proposed Memory Ownership PMA (Smmtt)
Hi Priv TG, In various TGs under the Security HC, and in discussions with folks from this Priv TG, we have been discussing the concept of a dynamic PMA for physical memory isolation (page granular). T
