selftests/vDSO: remove duplicate compiler invocations from Makefile

2024-07-05T20:12:34Z

The Makefile open-codes compiler invocations that ../lib.mk already provides. Avoid this by using a Make feature that allows setting per-target variables, which in this case are: CFLAGS and LDFLAGS. This approach generates the exact same compiler invocations as before, but removes all of the code duplication, along with the quirky mangled variable names. So now the Makefile is smaller, less unusual, and easier to read. The new dependencies are listed after including lib.mk, in order to let lib.mk provide the first target ("all:"), and are grouped together with their respective source file dependencies, for visual clarity.

selftests/vDSO: remove partially duplicated "all:" target in Makefile

2024-07-05T20:12:28Z

There were a couple of errors here: 1. TEST_GEN_PROGS was incorrectly prepending $(OUTPUT) to each program to be built. However, lib.mk already does that because it assumes "bare" program names are passed in, so this ended up creating $(OUTPUT)/$(OUTPUT)/file.c, which of course won't work as intended. 2. lib.mk was included before TEST_GEN_PROGS was set, which led to lib.mk's "all:" target not seeing anything to rebuild. So nothing worked, which caused the author to force things by creating an "all:" target locally--while still including ../lib.mk. Fix all of this by including ../lib.mk at the right place, and removing the $(OUTPUT) prefix to the programs to be built, and removing the duplicate "all:" target.

kselftest: Move test_vdso to the vDSO test suite

kselftest: Extend vDSO selftest to clock_getres

2020-10-27T23:58:00Z

The current version of the multiarch vDSO selftest verifies only gettimeofday. Extend the vDSO selftest to clock_getres, to verify that the syscall and the vDSO library function return the same information. The extension has been used to verify the hrtimer_resoltion fix.

kselftest: Extend vDSO selftest

2020-10-27T23:57:08Z

The current version of the multiarch vDSO selftest verifies only gettimeofday. Extend the vDSO selftest to the other library functions: - time - clock_getres - clock_gettime The extension has been used to verify the unified vdso library on the supported architectures.

kselftest: Enable vDSO test on non x86 platforms

2020-10-27T23:51:55Z

Currently the vDSO tests are built only on x86 platforms and cannot be cross compiled. Enable vDSO TARGET for all the platforms. Future patches will extend the tests. Cc: Shuah Khan Signed-off-by: Vincenzo Frascino Acked-by: Thomas Gleixner Signed-off-by: Shuah Khan

selftests: vdso: Add a selftest for vDSO getcpu()

2020-05-22T17:05:07Z

Provide a very basic selftest for getcpu() which similarly to our existing test for gettimeofday() looks up the function in the vDSO and prints the results it gets if the function exists and succeeds. Signed-off-by: Mark Brown Signed-off-by: Shuah Khan

selftests: vdso: Rename vdso_test to vdso_test_gettimeofday

2020-05-22T15:49:49Z

Currently the vDSO kselftests have a test called vdso_test which tests the vDSO implementation of gettimeofday(). In preparation for adding tests for other vDSO functionality rename this test to reflect what's going on. Signed-off-by: Mark Brown Signed-off-by: Shuah Khan

selftests: vDSO - fix to exclude x86 test on non-x86 platforms

2018-07-11T16:14:14Z

Fix to exclude vdso_standalone_test_x86 test from building on non-x86 platforms. In addition, fix it to use TEST_GEN_PROGS which is the right variable to use for generated programs. TEST_PROGS is for shell scripts. Signed-off-by: Shuah Khan (Samsung OSG)
