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-v5
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-v5-with-act)
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
