[RFC PATCH v2 0/7] support subsets of scalar crypto extension


From: liweiwei
Subject: [RFC PATCH v2 0/7] support subsets of scalar crypto extension
Date: Tue, 16 Nov 2021 16:06:14 +0800

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-v2

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-v2-with-act)

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
