kvm-unit-tests: bump version to fix build issue

2017-11-20T21:11:47+00:00

Since binutils commit 1a9ccd70f9a7 ("Fix the linker so that it will not silently generate ELF binaries with invalid program headers. Fix readelf to report such invalid binaries.") the behaviour has changed and binutils tries to create a program header segment for which there is no space. Thanks to Nicholas Piggin and his patch to Linux: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/commit/?h=next&id=ff45000fcb56b5b0f Cedric fixed this in kvm-unit-tests commit 95062c20790d ("powerpc: add -n to LDFLAGS") so bump to that version. Since the patch 0001-remove-werror.patch needs to be adjusted, we take this opportunity to reformat is as a Git patch.

kvm-unit-test: x86-64 variant only available on x86-64 hosts

2017-11-05T20:32:31+00:00

We use the host compiler for x86-64 builds, so ensure it is only available on x86-64 hosts. Signed-off-by: Peter Korsgaard Signed-off-by: Arnout Vandecappelle (Essensium/Mind)

package/kvm-unit-test: available for big.LITTLE arm cores too

2017-07-22T21:29:41+00:00

Since it supports each variants individually, it should also supports the big.LITTLE configurations. Signed-off-by: "Yann E. MORIN" Cc: Cyril Bur Cc: Thomas Petazzoni Signed-off-by: Thomas Petazzoni

package/kvm-unit-tests: introduce _ARCH_SUPPORTS

2017-07-22T21:26:44+00:00

Move all architecture options to their own symbol, so that it is easier to add more variants in the future. The dependency on cross-gcc >= 4.5 is only valid for i386, as we use the host gcc for x86_64. Adapt the dependency accordingly. Signed-off-by: "Yann E. MORIN" Cc: Cyril Bur [Thomas: - add comment about host gcc >= 4.5 dependency on x86-64 - remove bogus "depends on ... if ..." construct.] Signed-off-by: Thomas Petazzoni

kvm-unit-tests: fix build on x86-64 with specific gcc versions

2017-05-11T20:13:19+00:00

kvm-unit-tests uses the following code on x86/x86-64: static inline u64 scale_delta(u64 delta, u64 mul_frac) { u64 product, unused; __asm__ ( "mul %3" : "=d" (product), "=a" (unused) : "1" (delta), "rm" ((u64)mul_frac) ); return product; } The "mul" instruction does not have a suffix that indicates the width of the data being multiplied. When the data is passed in a register, there is no need to specify the width, but with some gcc versions, the data is passed as a memory reference, and therefore the assembler does not know the width of the data to be multiplied. It causes the following build failure: x86/hyperv_clock.c: Assembler messages: x86/hyperv_clock.c:21: Error: no instruction mnemonic suffix given and no register operands; can't size instruction Since the data being multiplied is 64 bit, we explicitly specify the instruction as being "mulq".

package/k*/Config.in: fix ordering of statements

2017-05-01T09:39:51+00:00

The check-package script when ran gives warnings on ordering issues on all of these Config files. This patch cleans up all warnings related to the ordering in the Config files for packages starting with the letter k in the package directory. The appropriate ordering is: type, default, depends on, select, help See http://nightly.buildroot.org/#_config_files for more information. Signed-off-by: Adam Duskett Signed-off-by: Thomas Petazzoni

package: use SPDX short identifier for LGPLv2/LGPLv2+

2017-04-01T13:19:13+00:00

We want to use SPDX identifier for license string as much as possible. SPDX short identifier for LGPLv2/LGPLv2+ is LGPL-2.0/LGPL-2.0+.

kvm-unit-tests: only enable for ARM on Cortex-A{7,12,15,17}

2016-11-20T14:48:10+00:00

The library uses the hypervisor instruction HVC, which is only available on ARMv7-A with Hypervisor extensions. This is limited to Cortex-A{7,12,15,17}. In addition the build unconditionally passes -marm so it also needs ARM instructions to be available, but that is already implied by the CPU selection. Implicitly fixes http://autobuild.buildroot.net/results/53d109fd9055fd20387bb857aced5f89cf3086fd though it is still not clear why ld doesn't accept the -Ttext=... option there.
