openblas: fix build with musl libc

2018-04-25T21:02:10+00:00

Add upstream patches to avoid use of __GLIBC_PREREQ when this macro is not defined.

openblas: bump version to v0.2.20

2018-04-01T10:45:13+00:00

Drop 0001-Complete-support-for-MIPS-n32-ABI.patch as it is now upstream and rebase 0002-Makefile.arm-remove-march-flags.patch. Also add a hash for the license file. Signed-off-by: Peter Korsgaard

openblas: drop SSE_GENERIC target

2018-04-01T10:43:15+00:00

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 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

arch: add Atom CPUs as Silvermont Architecture target

2018-01-01T12:05:16+00:00

The old Atom target is not really fitting for recent Atom CPUs based on Silvermont, Airmont or Goldmont. Those have more in common with older Desktop CPUs than old Atoms. Signed-off-by: Norbert Lange Signed-off-by: Thomas Petazzoni

openblas: SPARC support is for Sparc v9

2017-05-13T14:09:53+00:00

Makefile.sparc in the openblas source code passes -mcpu=v9, i.e it assumes a SPARCv9 CPU. Therefore, this commit adjusts openblas Config.in file so that SPARC is only used for BR2_sparc_v9.

boot, package: use SPDX short identifier for BSD-3c

2017-04-01T13:26:57+00:00

We want to use SPDX identifier for license string as much as possible. SPDX short identifier for BSD-3c is BSD-3-Clause. This change is done using following command. find . -name "*.mk" | xargs sed -ri '/LICENSE( )?[\+:]?=/s/BSD-3c/BSD-3-Clause/g' Signed-off-by: Rahul Bedarkar Signed-off-by: Thomas Petazzoni

openblas: disable OpenMP

2016-11-21T20:44:58+00:00

For powerpc (and powerpc only), the openblas build system will enable USE_OPENMP when threads are enabled. But the toolchain wasn't necessarily built with OpenMP support. So explicitly disable OpenMP - for all architectures, not just powerpc, just to keep things simple. We could have autodetected whether OpenMP is available at configure time, but that would be more of a feature patch, it's up to upstream to do that.

openblas: fix build with old binutils versions

2016-08-22T20:21:11+00:00

Older toolchains that use binutils <= 2.23.2 are affected by binutils bug #14887 (https://sourceware.org/bugzilla/show_bug.cgi?id=14887), where: someinstruction [ foo, something ] is not accepted, due to the whitespace after [ and before ], causing the following build failures for OpenBLAS: ARM register expected -- `pld [ r1,#512 ]' Since we don't have any mechanism to add dependencies on binutils versions, we work around this problem by patching the code to remove the problematic whitespaces. As there are many many instances of this in the ARM assembly code of OpenBLAS, we use a sed expression to make this modification rather than a patch. Fixes: http://autobuild.buildroot.net/results/43e50b480b4aea0fdec745d7875c85377c114cac/ [Peter: use single quotes in sed invocation] Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard
