* kernel-selftest: do not run 'make clean'Nora Schiffer2026-06-091-0/+2
| | | | | | | | | | | | | Due to the way the kernel-selftest sources are set up, the toplevel Makefile does not work and `make clean` will always result in a "The source tree is not clean, please run 'make ARCH=... mrproper'" error. Avoid running it by setting CLEANBROKEN = "1", so rebuilding the recipe without a clean (which often happens when the kernel has changed) does not fail.

* kernel-selftest: add libcap to build and runtime dependenciesTelukula Jeevan Kumar Sahu2026-06-071-2/+2
| | | | | | | | | | | | | | libcap is needed unconditionally for capability-aware tests such as breakpoints, cgroup, clone3, futex, ptrace, and seccomp. Add it to DEPENDS so it is always available at build time and to RDEPENDS so the installed tests can call cap_get_proc() and friends at runtime. bash and libgcc are also added to RDEPENDS: bash is required by several test shell scripts, and libgcc provides libgcc_s.so needed by tests that use GCC-emitted unwinding stubs.

* kernel-selftest: fix mm selftests dependenciesJoao Marcos Costa2026-04-202-1/+82
| | | | | | | | | | | | | | | | | Add numa (numactl), as required by rmap, migration, and others. Add liburing, otherwise some tests would be disabled. Moreover, liburing's availability is checked in a shell script executed prior to the compilation of the individual test cases. This script, however, does not read CFLAGS. Backport a fix [1] from mainline to address this issue.

* kernel-selftest: drop libhugetlbfsJoao Marcos Costa2026-04-201-7/+4
| | | | | | | | | | | | | | | | The support of libhugetlbfs was removed from mainline Linux a while ago, since v6.1 [1]. Since libhugetlbfs was the main reason to remove 'mm' selftests for some specific architectures, the respective operations should only remove bpf. Update the recipe to remove libhugetlbfs as a dependency of mm, and thus unblock this test category for some targets.

| | | | | | | | | | | | | | | | | The PTP selftest fails to compile with kernel versions 6.7+ due to missing header definitions for PTP_MASK_CLEAR_ALL and PTP_MASK_EN_SINGLE. These definitions were introduced in kernel v6.7 with commit c5a445b. This fix adds kernel headers to CFLAGS during compilation to ensure the required definitions are available.

* kernel-selftest: Update to allow for turning on all testsRyan Eatmon2024-10-111-16/+10
| | | | | | | | | | | | | | | | | | | | | | | | In testing adding in more kernel-selftests there were a number of issues that arose that require changes that are more appropriate for the main recipe and not a bbappend. 1) Stop looping over TEST_LIST ourselves and use the TARGETS="" provided by the kernel-sefltest Makefiles. This correctly sets up various variables that the selftest Makefiles all need. Also, do_install becomes cleaner because the main Makefile already installs the list of tests and the top level script. 2) Add DEBUG_PREFIX_MAP to the CC setting to avoid some "buildpaths" QA errors. 3) Add two INSANE_SKIPS for "already-stripped" and "ldflags". Some of the selftest Makefiles are adding flags to their compiles that basically break the above checks. Since these compiles are not really meant as user level tools and instead testing, it should be ok to just always set INSANE_SKIP for these two.
