From 14cf68a48a2ef95c214e445e96c25f0dd90f7aac Mon Sep 17 00:00:00 2001 From: Jan-Simon Moeller Date: Fri, 15 Dec 2023 20:55:06 +0100 Subject: Enhance DEFAULTTUNE mechanism This commit enhances the way we select the DEFAULTTUNE. DEFAULTTUNE in AGL is meant to be set to either corei7-64 for x86-64 aarch64 for 64bit ARM armv7vethf-neon-vfpv4 for 32bit ARM (where applicable) The reason is that we do want to work towards a binary distro and also maximize sstate reuse between platforms. Each and every board having different settings is counter-productive here. The original setting was done in SPEC-491. See this presentation: https://docs.google.com/presentation/d/1_VSGfheItufCCP_rbGBDg3-2miCyh02-yZva6m8cyUE The enhancement is that we introduce a variable 'AGL_DEFAULTTUNE' that a user could override if he really needs to change the defaults. Also we introduce OVERRIDES to help support this mechanism (agldefaulttune, forcedefaulttune).
