This patchset implements RISC-V scalar crypto extension v1.0.0 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-v9 To test rvk implementation, specify cpu argument with 'zks=true,zkn=true' or "zbkb=true,zbkc=true,zbkx=true,zknd=true,zkne=true,zknh=true,zksed=true,zksh=true,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-v9-with-act) Review status: patch 1~9 and 14 are acked or reviewed by Alistair Francis patch 2~11 are reviewed by Richard Henderson patch 5 is reviewed by Philippe Mathieu-Daudé v9: * check whether seed is accessed by a read-write instruction in helper_csrr. * fix disas for partial scalar crypto instructions * rebase on https://lists.nongnu.org/archive/html/qemu-riscv/2022-03/msg00156.html v8: * replace large macro for trans function of sha256/512 instructions with parameters to gen_sha* function in patch 8,9,10 * fix tcg_const_tl to tcg_constant_tl * fix rmw_seed function v7: * reuse gen_unary/gen_arith to simplify trans_* functions * replace DEF_HELPER_* with DEF_HEPER_FLAG_* * move aes64 related macros from patch 6 to patch 7 * create common helper gen_aes32_sm4 for aes32 and sm4 related instructions * replace bs with shamt (bs << 3) * optimize trans function for sha256, sha512 and sm4 instructions to be generated inline v6: * add reviewed-by tags * rebase on upstream v5: * split the big patches v4: * drop "x-" in exposed properties * delete unrelated changes 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 Weiwei Li (14): target/riscv: rvk: add cfg properties for zbk* and zk* target/riscv: rvk: add support for zbkb extension target/riscv: rvk: add support for zbkc extension target/riscv: rvk: add support for zbkx extension crypto: move sm4_sbox from target/arm target/riscv: rvk: add support for zknd/zkne extension in RV32 target/riscv: rvk: add support for zkne/zknd extension in RV64 target/riscv: rvk: add support for sha256 related instructions in zknh extension target/riscv: rvk: add support for sha512 related instructions for RV32 in zknh extension target/riscv: rvk: add support for sha512 related instructions for RV64 in zknh extension target/riscv: rvk: add support for zksed/zksh extension 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 | 49 +++ disas/riscv.c | 173 ++++++++++- include/crypto/sm4.h | 6 + target/arm/crypto_helper.c | 36 +-- target/riscv/bitmanip_helper.c | 80 +++++ target/riscv/cpu.c | 36 +++ target/riscv/cpu.h | 13 + target/riscv/cpu_bits.h | 9 + target/riscv/crypto_helper.c | 302 +++++++++++++++++++ target/riscv/csr.c | 68 +++++ target/riscv/helper.h | 22 ++ target/riscv/insn32.decode | 97 ++++-- target/riscv/insn_trans/trans_rvb.c.inc | 116 +++++++- target/riscv/insn_trans/trans_rvk.c.inc | 380 ++++++++++++++++++++++++ target/riscv/meson.build | 3 +- target/riscv/op_helper.c | 9 + target/riscv/pmp.h | 8 +- target/riscv/translate.c | 8 + 19 files changed, 1345 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
