2019-09-18kernel-selftest: Exclude from world buildsKhem Raj
Avoid need for installing clang on host, or depending on meta-clang Signed-off-by: Khem Raj <raj.khem@gmail.com>
2019-09-09kernel-selftest: Needs error.h which is missing in muslKhem Raj
prog_tests/flow_dissector.c:3:10: fatal error: error.h: No such file or directory | #include <error.h> | ^~~~~~~~~ Signed-off-by: Khem Raj <raj.khem@gmail.com>
2019-08-29kernel-selftest: Explicitly disable stack protectorKhem Raj
selftests do not support it and clang from meta-clang builds with this turned on by default Disable security flags completely, drop all workarounds used to get around the hoop Signed-off-by: Khem Raj <raj.khem@gmail.com>
2019-08-29kernel-selftest: Warn conditionally about clang-native dependencyKhem Raj
When meta-clang is in mix then it does the right thing already so no need to warn in that case Signed-off-by: Khem Raj <raj.khem@gmail.com>

2018-10-27kernel-selftest: temporary disable bpf for arm - fix build for qemuarmAndrea Adami
Even running on 32bit the bpf objects are 64bit: this triggers the QA about bitsize mismatch 32 vs. 64. Besides, objdump does not recognize the arch 0xf7. Trying the workaround to use the llvm-objdump and setting TOOLCHAIN = "clang" the build for arm fails on libcxx |include/c++/8.2.0/atomic:250: undefined reference to `__atomic_load_4' Temporary disable bpf as done for x86/32bit as it seems still unstable.

* (Depends upon a linux-libc-headers patch proposed to oe-core) * Delete unused patch * Mark Clang 6.0 as minimum required version * Do not hardcode python3 interpreter path Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Hongzhi.Song <hongzhi.song@windriver.com> Cc: Martin Jansa <Martin.Jansa@gmail.com>
2018-08-28kernel-selftest: Fix the COPYING checksum variablityKhem Raj
COPYING coming from kernel sources but the md5 is static value saved in recipe does not scale to all kind of machines which may have different kernel providers filling in, therefore keep a static copy of COPYING file as well, additionally copy LICENSES directory ( if it exists) into sources where all the real license texts are living Document need for clang Signed-off-by: Khem Raj <raj.khem@gmail.com>

2018-08-02kernel-selftest: Add a recipe on kernel selftestHongzhi.Song
The recipe builds the framework for kernel-selftest. Now, it just contains two sets of testcase, bpf and vm. We will append more to this recipe. The following kernel config fragments must be manually enabled, i.e. in local.conf, to use this test suite. KERNEL_FEATURES_append += "features/bpf/bpf.scc \ cfg/debug-kselftest.scc \ features/hugetlb/hugetlb.scc \ " Signed-off-by: Hongzhi.Song <hongzhi.song@windriver.com> Signed-off-by: Khem Raj <raj.khem@gmail.com>
