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 v20230620 version of the specification(1)(168e7b4).
This is an update to the patchset submitted to qemu-devel on
Tue, 27 Jun 2023 09:43:24 -0700
Based-on: 20230620110758.787479-1-richard.hender...@linaro.org
([PATCH v3 00/37] crypto: Provide aes-round.h and host accel)
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.
v4:
New patch 08/17 fixes the tcg_gen_gvec_andcs temporary variable
issue.
Patch 09/17 fixes imm mode for vror.vi.
Rebased to riscv-to-apply.next branch (de395bb):
Replace vstart constraint checking by TCG op.
Verified by code examples provided by vector crypto spec repository
(riscv-crypto).
v5:
Imported aes-round.h for Zvkned extension.
Rebased to 20230620110758.787479-1-richard.hender...@linaro.org
Exposed the properties of v4 patch 17/17 to the patches that the
extension was added.
Removed v4 patch 08/17 that is queued to tcg-next.
As v20230620 is a frozen version, 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.
