This patchset provides an implementation for Zvbb, Zvbc, Zvkned, Zvknh, Zvksh, Zvkg, and Zvksed of the draft RISC-V vector cryptography extensions as per the v20230425 version of the specification(1) (6a7ae7f2). This is an update to the patchset submitted to qemu-devel on Monday, 17 Apr 2023 14:58:36 +0100.
v2:
squashed commits into one commit per extension with separate commits for
each refactoring
unified trans_rvzvk*.c.inc files into one trans_rvvk.c.inc
style fixes in insn32.decode and other files
added macros for EGS values in translation functions.
updated from v20230303 to v20230407 of the spec:
Zvkb has been split into Zvbb and Zvbc
vbrev, vclz, vctz, vcpop and vwsll have been added to Zvbb.
v3:
New patch 03/19 removes redundant “cpu_vl == 0” checks from trans_rvv.c.inc
Introduction of new tcg ops has been factored out of patch 11/19 and into 09/19
These ops are now added to non riscv-specific files
As v20230425 is a freeze candidate, we are not expecting any significant changes to the specification or this patch series.
Please note that the Zvkt data-independent execution latency extension (and all extensions including it) has not been implemented, and we would recommend not using these patches in an environment where timing attacks are an issue.
Work performed by Dickon, Lawrence, Nazar, Kiran, and William from Codethink sponsored by SiFive, as well as Max Chou and Frank Chang from SiFive.
For convenience we have created a git repo with our patches on top of a recent master. https://github.com/CodethinkLabs/qemu-ct
