New AMD Ryzen 5000 processors support VAES instructions with
256-bit AVX2 registers. Camellia AES-NI/AVX2 implementation
had to split 256-bit vector for AES processing, but now we
can use those 256-bit registers directly with VAES.
Benchmarks on AMD Ryzen 5800X:
Before (AES-NI/AVX2):
CAMELLIA128 | nanosecs/byte mebibytes/sec cycles/byte auto Mhz
CBC dec | 0.539 ns/B 1769 MiB/s 2.62 c/B 4852
CFB dec | 0.528 ns/B 1806 MiB/s 2.56 c/B 4852±1
CTR enc | 0.552 ns/B 1728 MiB/s 2.68 c/B 4850
OCB enc | 0.550 ns/B 1734 MiB/s 2.65 c/B 4825
OCB dec | 0.577 ns/B 1653 MiB/s 2.78 c/B 4825
OCB auth | 0.546 ns/B 1747 MiB/s 2.63 c/B 4825
After (VAES/AVX2, CBC-dec ~13%, CFB-dec/CTR/OCB ~20% faster):
CAMELLIA128 | nanosecs/byte mebibytes/sec cycles/byte auto Mhz
CBC dec | 0.477 ns/B 1999 MiB/s 2.31 c/B 4850
CFB dec | 0.433 ns/B 2201 MiB/s 2.10 c/B 4850
CTR enc | 0.438 ns/B 2176 MiB/s 2.13 c/B 4851
OCB enc | 0.449 ns/B 2122 MiB/s 2.18 c/B 4850
OCB dec | 0.468 ns/B 2038 MiB/s 2.27 c/B 4850
OCB auth | 0.447 ns/B 2131 MiB/s 2.17 c/B 4850
