From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Korsgaard Date: Sun, 1 Apr 2018 10:46:41 +0200 Subject: [Buildroot] [PATCH 1/2] openblass: drop SSE_GENERIC target Message-ID: <20180401084642.15199-1-peter@korsgaard.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Fixes #10856 The SSE_GENERIC target fails to build with a "sgemm_kernel.o: No such file or directory" error. 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. 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 Signed-off-by: Peter Korsgaard --- package/openblas/Config.in | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/package/openblas/Config.in b/package/openblas/Config.in index eb93e319e4..8f514685a1 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 @@ -16,7 +16,6 @@ config BR2_PACKAGE_OPENBLAS_DEFAULT_TARGET default "BARCELONA" if BR2_x86_barcelona 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 -- 2.11.0
