From 3a14dbc32bc4ebf9064c3b038eaca67356579610 Mon Sep 17 00:00:00 2001 From: krant Date: Fri, 16 Feb 2024 14:46:45 +0200 Subject: [PATCH] openblas: enable ARM-specific optimizations OpenBLAS allows to specify per-family CPU optimizations during build stage. This package supports manual specification of a family during configuration. This commit adds automatic detection of target family, while keeping manual override as a backup. Automatically detected ARM families: - Cortex-A9 without NEON - Cortex-A9 with NEON - Cortex-A15 - Cortex-A53 - Cortex-A72 Signed-off-by: krant --- libs/openblas/Makefile | 19 ++++++++++++++++--- 1 file changed, 16 insertions(+), 3 deletions(-) diff --git a/libs/openblas/Makefile b/libs/openblas/Makefile index 3a44db40df3167..715d35e1303b04 100644 --- a/libs/openblas/Makefile +++ b/libs/openblas/Makefile @@ -6,7 +6,7 @@ include $(TOPDIR)/rules.mk PKG_NAME:=OpenBLAS PKG_VERSION:=0.3.26 -PKG_RELEASE:=1 +PKG_RELEASE:=2 PKG_SOURCE:=OpenBLAS-$(PKG_VERSION).tar.gz PKG_SOURCE_URL:=https://github.com/xianyi/OpenBLAS/releases/download/v$(PKG_VERSION)/ @@ -49,13 +49,26 @@ endmenu endef OPENBLAS_TARGET=$(call qstrip,$(CONFIG_OPENBLAS_TARGET_OVERRIDE)) -CPU_TYPE=$(call qstrip,$(CONFIG_CPU_TYPE)) ifeq ($(OPENBLAS_TARGET),) # initialize to GENERIC as default OPENBLAS_TARGET:=GENERIC -ifeq ($(ARCH),aarch64) +ifneq ($(findstring cortex-a9,$(CONFIG_CPU_TYPE)),) + ifneq ($(findstring neon,$(CONFIG_CPU_TYPE)),) + # CORTEXA9 relies on NEON + OPENBLAS_TARGET:=CORTEXA9 + else + # Fallback for CPUs without NEON + OPENBLAS_TARGET:=ARMV7 + endif +else ifneq ($(findstring cortex-a15,$(CONFIG_CPU_TYPE)),) + OPENBLAS_TARGET:=CORTEXA15 +else ifneq ($(findstring cortex-a53,$(CONFIG_CPU_TYPE)),) + OPENBLAS_TARGET:=CORTEXA53 +else ifneq ($(findstring cortex-a72,$(CONFIG_CPU_TYPE)),) + OPENBLAS_TARGET:=CORTEXA72 +else ifeq ($(ARCH),aarch64) OPENBLAS_TARGET:=ARMV8 else ifeq ($(ARCH),arm) OPENBLAS_TARGET:=ARMV5
