selftests: fuxex: Report a unique test name per run of futex_requeue_pi

2024-02-19T22:00:51+00:00

The futex_requeue_pi test program is run a number of times with different
options to provide multiple test cases. Currently every time it runs it
reports the result with a consistent string, meaning that automated systems
parsing the TAP output from a test run have difficulty in distinguishing
which test is which.

The parameters used for the test are already logged as part of the test
output, let's use the same format to roll them into the test name that we
use with KTAP so that automated systems can follow the results of the
individual cases that get run.

selftests/futex: Order calls to futex_lock_pi

2023-08-16T16:48:10+00:00

Observed occassional failures in the futex_wait_timeout test:

ok 1 futex_wait relative succeeds
ok 2 futex_wait_bitset realtime succeeds
ok 3 futex_wait_bitset monotonic succeeds
ok 4 futex_wait_requeue_pi realtime succeeds
ok 5 futex_wait_requeue_pi monotonic succeeds
not ok 6 futex_lock_pi realtime returned 0
......

The test expects the child thread to complete some steps before
the parent thread gets to run. There is an implicit expectation
of the order of invocation of futex_lock_pi between the child thread
and the parent thread. Make this order explicit. If the order is
not met, the futex_lock_pi call in the parent thread succeeds and
will not timeout.

selftests: futex: Fix incorrect kernel headers search path

2023-02-13T16:09:44+00:00

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).

selftests/futex: fix build for clang

2022-10-18T20:13:11+00:00

Don't use the test-specific header files as source files to force a
target dependency, as clang will complain if more than one source file
is used for a compile command with a single '-o' flag.

Use the proper Makefile variables instead as defined in
tools/testing/selftests/lib.mk.

selftests: stop using KSFT_KHDR_INSTALL

2022-07-11T23:23:30+00:00

Stop using the KSFT_KHDR_INSTALL flag as installing the kernel headers
from the kselftest Makefile is causing some issues.  Instead, rely on
the headers to be installed directly by the top-level Makefile
"headers_install" make target prior to building kselftest.

selftests: futex: Add the uapi headers include variable

2022-02-24T00:20:32+00:00

Out of tree build of this test fails if relative path of the output
directory is specified. KBUILD_OUTPUT also doesn't point to the correct
directory when relative path is used. Thus out of tree builds fail.
Remove the un-needed include paths and use KHDR_INCLUDES to correctly
reach the headers.

selftests: futex: set DEFAULT_INSTALL_HDR_PATH

2022-02-24T00:14:36+00:00

If only futex selftest is compiled, uapi header files are copied to the
selftests/futex/functional directory. This copy isn't needed. Set the
DEFAULT_INSTALL_HDR_PATH variable to 1 to use the default header install
path only. This removes extra copy of header file.

selftests: futex: Use variable MAKE instead of make

2022-01-27T23:29:23+00:00

Recursive make commands should always use the variable MAKE, not the
explicit command name ‘make’. This has benefits and removes the
following warning when multiple jobs are used for the build:

make[2]: warning: jobserver unavailable: using -j1.  Add '+' to parent make rule.
