This patchset implements RISC-V K-extension v1.0.0.rc5 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
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-with-act)
liweiwei (6):
target/riscv: rvk: add flag support for Zbk[bcx]
target/riscv: rvk: add implementation of instructions for Zbk* -
reuse partial instructions of Zbb/Zbc extensions - add brev8 packh,
unzip, zip, etc.
target/riscv: rvk: add flag support for
Zk/Zkn/Zknd/Zknd/Zkne/Zknh/Zks/Zksed/Zksh/Zkr
target/riscv: rvk: add implementation of instructions for Zk*
target/riscv: rvk: add CSR support for Zkr: - add SEED CSR - add
USEED, SSEED fields for MSECCFG CSR
disas/riscv.c: rvk: add disas support for Zbk* and Zk* instructions
