This patchset implements virtual memory related RISC-V extensions: Svnapot version 1.0, Svinval vesion 1.0, Svpbmt version 1.0.
Specification: https://github.com/riscv/virtual-memory/tree/main/specs The port is available here: https://github.com/plctlab/plct-qemu/tree/plct-virtmem-upstream-v5 To test this implementation, specify cpu argument with 'svinval=true,svnapot=true,svpbmt=true'. This implementation can pass the riscv-tests for rv64ssvnapot. v5: * merge patch https://lore.kernel.org/qemu-devel/1569456861-8502-1-git-send-email-guo...@kernel.org/ * fix type compatibility in RV32 v4: * fix encodings for hinval_vvma and hinval_gvma * partition inner PTE check into several steps * improve commit messages to describe changes v3: * drop "x-" in exposed properties v2: * add extension check for svnapot and svpbmt Guo Ren (1): target/riscv: Ignore reserved bits in PTE for RV64 Weiwei Li (4): target/riscv: add PTE_A/PTE_D/PTE_U bits check for inner PTE target/riscv: add support for svnapot extension target/riscv: add support for svinval extension target/riscv: add support for svpbmt extension target/riscv/cpu.c | 4 ++ target/riscv/cpu.h | 3 + target/riscv/cpu_bits.h | 10 +++ target/riscv/cpu_helper.c | 23 ++++++- target/riscv/insn32.decode | 7 ++ target/riscv/insn_trans/trans_svinval.c.inc | 75 +++++++++++++++++++++ target/riscv/translate.c | 1 + 7 files changed, 120 insertions(+), 3 deletions(-) create mode 100644 target/riscv/insn_trans/trans_svinval.c.inc -- 2.17.1
