Subject: [PATCH] Optimize AES-GCM for uarchs with unroll and new instructions
|
|
|
|
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).
