From 213c397492bdc64cf26b2e7b3877e4a29dc9f8da Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Mon, 28 Feb 2022 16:18:44 +0100 Subject: passt, pasta: Run-time selection of AVX2 build Build-time selection of AVX2 flags and routines is not practical for distributions, but limiting AVX2 usage to checksum routines with specific run-time detection doesn't allow for easy performance gains from auto-vectorisation of batched packet handling routines. For x86_64, build non-AVX2 and AVX2 binaries, and implement a simple wrapper replacing the current executable with the AVX2 build if it's available, and if AVX2 is supported by the current CPU.
