Page-Based Memory Types (Svpbmt)
Today’s @risc_v Tip:
A new version of the RISC-V Privileged Architecture (v1.12) was released on Dec 3rd. One of the larger changes is the addition of the “Page-Based Memory Types” extension (Svpbmt). It is configured in leaf PTE bits [62:61] in Sv39, Sv48, and the new Sv57.
