This patchset implements virtual memory related RISC-V extensions: Svnapot version 0.1, Svinval vesion 0.1, Svpbmt version 0.1.
Specification:
https://github.com/riscv/virtual-memory/tree/main/specs
The port is available here:
https://github.com/plctlab/plct-qemu/tree/plct-vritmem-upstream
To test svinval implementation, specify cpu argument with 'x-svinval=true'. Other two extensions are enabled by default.
This implementation can pass the riscv-tests for rv64ssvnapot.
