This patchset implements RISC-V K-extension v1.0.0.rc6 version instructions. Partial instructions are reused from B-extension.
Specification: https://github.com/riscv/riscv-crypto The port is available here: https://github.com/plctlab/plct-qemu/tree/plct-k-upstream-v3 To test rvk implementation, specify cpu argument with 'x-zks=true,x-zkn=true' or "x-zbkb=true,x-zbkc=true,x-zbkx=true,x-zknd=true,x-zkne=true,x-zknh=true,x-zksed=true,x-zksh=true,x-zkr=true" to enable K-extension support. This implementation can pass the ACT tests for K with our extended act support for qemu (available at https://github.com/plctlab/plct-qemu/tree/plct-k-upstream-v3-with-act) v3: * add extension check for SEED csr access v2: * optimize implementation for brev8, xperm, zip, unzip * use aes related sbox array from crypto/aes.h * move sm4_sbox to crypto/sm4.c, and share it with target/arm liweiwei (7): target/riscv: rvk: add cfg properties for zbk* and zk* target/riscv: rvk: add implementation of instructions for Zbk* crypto include/crypto target/arm: move sm4_sbox to crypto target/riscv: rvk: add implementation of instructions for Zk* target/riscv: rvk: add CSR support for Zkr disas/riscv.c: rvk: add disas support for Zbk* and Zk* instructions target/riscv: rvk: expose zbk* and zk* properties crypto/meson.build | 1 + crypto/sm4.c | 48 +++ disas/riscv.c | 171 ++++++++- include/crypto/sm4.h | 6 + meson | 2 +- target/arm/crypto_helper.c | 36 +- target/riscv/bitmanip_helper.c | 74 ++++ target/riscv/cpu.c | 36 ++ target/riscv/cpu.h | 13 + target/riscv/cpu_bits.h | 9 + target/riscv/crypto_helper.c | 446 ++++++++++++++++++++++ target/riscv/csr.c | 73 ++++ target/riscv/helper.h | 48 +++ target/riscv/insn32.decode | 94 ++++- target/riscv/insn_trans/trans_rvb.c.inc | 127 ++++++- target/riscv/insn_trans/trans_rvk.c.inc | 467 ++++++++++++++++++++++++ target/riscv/meson.build | 1 + target/riscv/pmp.h | 8 +- target/riscv/translate.c | 8 + 19 files changed, 1597 insertions(+), 71 deletions(-) create mode 100644 crypto/sm4.c create mode 100644 include/crypto/sm4.h create mode 100644 target/riscv/crypto_helper.c create mode 100644 target/riscv/insn_trans/trans_rvk.c.inc -- 2.17.1
