selftests: move vDSO tests from Documentation/vDSO

2016-09-20T15:58:04Z

Remove vDSO from Makefile to move the to selftests. Update vDSO Makefile to work under selftests. vDSO will not be run as part of selftests suite and will not be included in install targets. They can be built separately for now. Acked-by: Jonathan Corbet Signed-off-by: Shuah Khan

Documentation/vDSO: don't build tests when cross compiling

2015-06-22T22:04:57Z

The following was seen in linux-next build coverage, which is somewhat unique since it uses powerpc host to cross compile x86: Documentation/vDSO/vdso_standalone_test_x86.c:49:2: error: impossible register constraint in 'asm' make[4]: *** [Documentation/vDSO/vdso_standalone_test_x86.o] Error 1 It probably makes sense to just skip building these tests when we are cross compiling.

vdso: don't require 64-bit math in standalone test

2014-10-25T14:53:44Z

The use of 64-bit math on i386 causes build failures: vdso_standalone_test_x86.c:(.text+0x101): undefined reference to `__umoddi3' vdso_standalone_test_x86.c:(.text+0x12d): undefined reference to `__udivdi3' Commit adb19fb66ee (Documentation: add makefiles for more targets) is now building this by default, so it's failing the kernel build entirely. Switching the declaration from uint64_t to time_t does the right thing and handles the x32 case automatically. Signed-off-by: Jeff Mahoney Acked-by: Peter Foley Signed-off-by: Jonathan Corbet

Documentation: fix vdso_standalone_test_x86 on 32-bit

2014-10-21T14:44:26Z

vdso_standalone_test_x86 needs -lgcc_s to build succesfully on 32bit. Signed-off-by: Peter Foley [ Fixed missing separator issue reported by Paul Bolle ] Signed-off-by: Jonathan Corbet

Documentation: disable vdso_test to avoid breakage with old glibc

2014-09-26T09:03:00Z

glibc versions older than 2.16 don't include sys/auxv.h which this executable uses. Since we don't have a good way to test for specific glibc versions in kbuild, just disable it for now. Signed-off-by: Peter Foley Signed-off-by: Randy Dunlap Signed-off-by: Jiri Kosina

x86/vdso/doc: Make vDSO examples more portable

2014-06-13T02:01:24Z

This adds a new vdso_test.c that's written entirely in C. It also makes all of the vDSO examples work on 32-bit x86.

x86/vdso/doc: Rename vdso_test.c to vdso_standalone_test_x86.c

2014-06-13T02:01:16Z

This thing is hopelessly x86_64-specific: it's an example of how to access the vDSO without any runtime support at all. Signed-off-by: Andy Lutomirski Link: http://lkml.kernel.org/r/3efc170e0e166e15f0150c9fdb37d52488b9c0a4.1402620737.git.luto@amacapital.net Signed-off-by: H. Peter Anvin
