Several upstream bug reports exist for this: https://github.com/xianyi/OpenBLAS/issues/502 https://github.com/xianyi/OpenBLAS/issues/685 In both cases, upstream suggests using a different target definition instead. E.G. from issue 685: You may use NORTHWOOD on x86: make TARGET=NORTHWOOD that uses SSE2 instructions. It's very hard to find non-SSE2 x86 CPUs today. For x86-64 use the PRESCOTT target So drop the SSE_GENERIC target. The only x86_64 variant we support not covered by a more specific openblas target is the default variant, nocona and jaguar. Nocona was a Xeon variant of the P4 "Prescott" architecture, so use the PRESCOTT openblas target: https://en.wikipedia.org/wiki/Xeon#Nocona_and_Irwindale Jaguar is from the Bobcat family, so use the BOBCAT openblas target: https://en.wikipedia.org/wiki/List_of_AMD_microprocessors#Bobcat_core_architecture_(APU) [Peter: add Jaguar as pointed out by Arnout] Signed-off-by: Peter Korsgaard (cherry picked from commit 5e6fa93483caac317ab8844feb2ae9c07078a6c8) Signed-off-by: Peter Korsgaard --- diff --git a/package/openblas/Config.in b/package/openblas/Config.in index eb93e319e4..8e71a43f98 100644 --- a/package/openblas/Config.in +++ b/package/openblas/Config.in @@ -3,7 +3,7 @@ config BR2_PACKAGE_OPENBLAS_DEFAULT_TARGET default "P2" if BR2_x86_pentium2 default "KATMAI" if BR2_x86_pentium3 default "NORTHWOOD" if BR2_x86_pentium4 - default "PRESCOTT" if BR2_x86_prescott + default "PRESCOTT" if BR2_x86_prescott || BR2_x86_nocona default "BANIAS" if BR2_x86_pentium_m default "CORE2" if BR2_x86_core2 default "NEHALEM" if BR2_x86_corei7 || BR2_x86_silvermont @@ -14,9 +14,9 @@ config BR2_PACKAGE_OPENBLAS_DEFAULT_TARGET default "OPTERON" if BR2_x86_opteron default "OPTERON_SSE3" if BR2_x86_opteron_sse3 default "BARCELONA" if BR2_x86_barcelona + default "JAGUAR" if BR2_x86_jaguar default "STEAMROLLER" if BR2_x86_steamroller default "VIAC3" if BR2_x86_c3 || BR2_x86_c32 - default "SSE_GENERIC" if BR2_X86_CPU_HAS_SSE default "POWER4" if BR2_powerpc_power4 default "POWER5" if BR2_powerpc_power5 default "POWER6" if BR2_powerpc_power6
