selftests: lib: Skip tests on missing test modules

2017-06-23T15:41:53+00:00

With older kernels, printf.sh and bitmap.sh fail because they can't find the respective test modules they are looking for. Use modprobe dry run to check for missing test_XXX module. Error out with the same error code as prime_numbers.sh. Signed-off-by: Sumit Semwal Signed-off-by: Shuah Khan

selftests: lib: add config fragment for bitmap, printf and prime numbers tests

2017-04-11T15:37:53+00:00

test_bitmap, test_printf and prime_numbers are expected to be built as modules. Signed-off-by: Fathi Boudra Tested-by: Naresh Kamboju Signed-off-by: Shuah Khan

lib: Add a simple prime number generator

2016-12-27T11:30:56+00:00

Prime numbers are interesting for testing components that use multiplies and divides, such as testing DRM's struct drm_mm alignment computations. v2: Move to lib/, add selftest v3: Fix initial constants (exclude 0/1 from being primes) v4: More RCU markup to keep 0day/sparse happy v5: Fix RCU unwind on module exit, add to kselftests v6: Tidy computation of bitmap size v7: for_each_prime_number_from() v8: Compose small-primes using BIT() for easier verification v9: Move rcu dance entirely into callers. v10: Improve quote for Betrand's Postulate (aka Chebyshev's theorem) Signed-off-by: Chris Wilson Cc: Lukas Wunner Reviewed-by: Joonas Lahtinen Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20161222144514.3911-1-chris@chris-wilson.co.uk

selftests/lib: set printf.sh executable

2016-06-27T19:17:14+00:00

Test for test_printf module fails always because the test program, printf.sh, has no execution permission. This commit adds execution permission to it. Signed-off-by: SeongJae Park Acked-by: Kees Cook Signed-off-by: Shuah Khan

test_bitmap: unit tests for lib/bitmap.c

2016-02-20T03:54:09+00:00

This is mainly testing bitmap construction and conversion to/from u32[] for now. Tested: qemu i386, x86_64, ppc, ppc64 BE and LE, ARM. Signed-off-by: David Decotigny Signed-off-by: David S. Miller

selftests: run lib/test_printf module

2015-11-07T01:50:42+00:00

This runs the lib/test_printf module to make sure printf is operating sanely. Signed-off-by: Kees Cook Cc: Rasmus Villemoes Cc: Shuah Khan Cc: Andy Shevchenko Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
