arch: allow GCC target options to be optionally overwritten

2018-09-23T20:17:57+00:00

The BR2_GCC_TARGET_* configuration variables are copied to corresponding GCC_TARGET_* variables which may then be optionally modified or overwritten by architecture specific makefiles. All makefiles must use the new GCC_TARGET_* variables instead of the BR2_GCC_TARGET_* versions. Signed-off-by: Mark Corbin [Thomas: simplify include of arch/arch.mk] Signed-off-by: Thomas Petazzoni

kvm-unit-tests: test for rdseed/rdrand

2018-01-14T14:08:37+00:00

The build fails when the host binutils isn't at least 2.23 (2.22.x introduced RDSEED). The host toolchain is used for x86_64 target builds where we need to do a 32bit build. Most other buildroot builds are using a much newer binutils unless it's a external older toolchain.

kvm-unit-tests: bump to kvm-unit-tests-20171020

2017-12-03T13:48:16+00:00

- 0001-Makefile-remove-Werror-to-avoid-build-failures.patch is adjusted to apply to the new version of kvm-unit-tests - 0001-x86-hyperv_clock-be-explicit-about-mul-instruction-d.patch is removed, as it has been merged upstream as of commit 45276b5860522921c77fb3ccc1458ff5f223c3c6.

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

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".
