From ac7a646fce132c70015bc0e3ed3e15dd7df4c4bb Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Tue, 21 Jan 2025 14:08:25 -0500 Subject: conf: machine: k3: Use Cortex-A53/A72 CPU tune All current K3 devices use either A53 or A72. Use the compile tune configuration specific for these to allow the compiler to make better optimizations. Default tune here is weakly set to a lowest common denominator of aarch64, as before, which is a recommended behavior for a BSP layer. This allows for greater binary reuse (packages, sstate, etc.) across different platforms of the same architecture in multi-BSP environments. At the same time, since all the correct tunes are now configured for K3 devices, one can elevate compiler optimization levels either from local.conf or own Distro configuration on a per-SoC or per-device basis, like so: DEFAULTTUNE:k3 = "armv8a-crc" DEFAULTTUNE:j721e = "cortexa72-cortexa53" DEFAULTTUNE:beagleplay = "cortexa72-cortexa53" Signed-off-by: Andrew Davis Signed-off-by: Denys Dmytriyenko --- meta-ti-bsp/conf/machine/include/k3.inc | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/meta-ti-bsp/conf/machine/include/k3.inc b/meta-ti-bsp/conf/machine/include/k3.inc index a296f64f..dd3cbeca 100644 --- a/meta-ti-bsp/conf/machine/include/k3.inc +++ b/meta-ti-bsp/conf/machine/include/k3.inc @@ -3,7 +3,8 @@ require conf/machine/include/ti-soc.inc SOC_FAMILY:append = ":k3" -require conf/machine/include/arm/arch-arm64.inc +DEFAULTTUNE ?= "aarch64" +require conf/machine/include/arm/armv8a/tune-cortexa72-cortexa53.inc require conf/machine/include/ti-bsp.inc -- cgit v1.2.3-54-g00ecf
