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-v4 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-v4-with-act) 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 (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 | 49 +++ disas/riscv.c | 170 +++++++++ include/crypto/sm4.h | 6 + target/arm/crypto_helper.c | 36 +- target/riscv/bitmanip_helper.c | 74 ++++ target/riscv/cpu.c | 37 ++ target/riscv/cpu.h | 13 + target/riscv/cpu_bits.h | 9 + target/riscv/crypto_helper.c | 446 ++++++++++++++++++++++ target/riscv/csr.c | 74 ++++ target/riscv/helper.h | 42 +++ 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 | 3 +- target/riscv/pmp.h | 8 +- target/riscv/translate.c | 8 + 18 files changed, 1594 insertions(+), 70 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
