2023-02-08Fix the return values of the aarch64 unroll8_eor_aes_gcm_*_*_kernel functionsTom Cosgrove
These aren't currently checked when they are called in cipher_aes_gcm_hw_armv8.inc, but they are declared as returning as size_t the number of bytes they have processed, and the aes_gcm_*_*_kernel (unroll by 4) versions of these do return the correct values.

2022-11-11Fix build issue with aes-gcm-armv8-unroll8_64.S on older aarch64 assemblersXiaokangQian
The EOR3 instruction is implemented with .inst, and the code here is enabled using run-time detection of the CPU capabilities, so no need to explicitly ask for the sha3 extension.

2022-11-11Optimize AES-GCM for uarchs with unroll and new instructionsXiaokangQian
Increase the block numbers to 8 for every iteration. Increase the hash table capacity. Make use of EOR3 instruction to improve the performance. This can improve performance 25-40% on out-of-order microarchitectures with a large number of fast execution units, such as Neoverse V1. We also see 20-30% performance improvements on other architectures such as the M1. Assembly code reviewd by Tom Cosgrove (ARM).
