The compile tests, benchmarks and the abi0-conflict regression test (unstable under QEMU) are excluded. The ust-elf test ships prebuilt, intentionally foreign-architecture ELF fixtures, so they are kept from being stripped and the related QA checks are relaxed for the ptest package. Tested on qemuriscv64 with ptest-runner. Signed-off-by: Pratik Farkase --- Notes: v2: Skip unit/ust-error on musl. It segfaults because lttng_ust_strerror() negates its argument (undefined for the INT_MIN the test passes) and then reads its lookup table out of bounds; this only shows up on musl. .../distro/include/ptest-packagelists.inc | 1 + meta/recipes-kernel/lttng/lttng-ust/run-ptest | 31 ++++++++++ meta/recipes-kernel/lttng/lttng-ust_2.16.0.bb | 60 ++++++++++++++++++- 3 files changed, 91 insertions(+), 1 deletion(-) create mode 100644 meta/recipes-kernel/lttng/lttng-ust/run-ptest diff --git a/meta/conf/distro/include/ptest-packagelists.inc b/meta/conf/distro/include/ptest-packagelists.inc index 74591a34f2..d5357d8732 100644 --- a/meta/conf/distro/include/ptest-packagelists.inc +++ b/meta/conf/distro/include/ptest-packagelists.inc @@ -64,6 +64,7 @@ PTESTS_FAST = "\ libxslt \ libyaml \ logrotate \ + lttng-ust \ lua \ lzo \ m4 \ diff --git a/meta/recipes-kernel/lttng/lttng-ust/run-ptest b/meta/recipes-kernel/lttng/lttng-ust/run-ptest new file mode 100644 index 0000000000..468562eb70 --- /dev/null +++ b/meta/recipes-kernel/lttng/lttng-ust/run-ptest @@ -0,0 +1,31 @@ +#!/bin/sh + +PTEST_PATH=$(dirname "$0") +cd "$PTEST_PATH/tests" || exit 1 + +export UST_TESTS_SRCDIR="$PTEST_PATH/tests" +export UST_TESTS_BUILDDIR="$PTEST_PATH/tests" + +TESTS=" +unit/libringbuffer/test_shm +unit/gcc-weak-hidden/test_gcc_weak_hidden +unit/libcommon/test_get_cpu_mask_from_sysfs +unit/libcommon/test_get_max_cpuid_from_mask +unit/libcommon/test_get_max_cpuid_from_sysfs +unit/libcommon/test_get_possible_cpus_array_len +unit/libmsgpack/test_msgpack +unit/pthread_name/test_pthread_name +unit/snprintf/test_snprintf +unit/ust-elf/test_ust_elf +unit/ust-error/test_ust_error +unit/ust-utils/test_ust_utils +" + +for test in $TESTS;
