Tue, 10 Sep 2024 01:10:34 +0000

lib/math: Add int_pow test suiteAdds test suite for integer based power function which performs integerexponentiation.The test suite is designed to verify that the implementation of int_powcorrectly computes the power of a given base raised to a given exponent.The tests check various scenarios and edge cases to ensure the accuracyand reliability of the exponentiation function.Updated commit with test information at commit time: Shuah KhanSigned-off-by: Luis Felipe Hernandez Reviewed-by: David Gow Signed-off-by: Shuah Khan List of files: /linux-6.15/lib/math/Makefile

Tue, 20 Apr 2021 02:50:28 +0000

lib/math: Add a `do_div' test moduleImplement a module for correctness and performance evaluation for the`do_div' function, often handled in an optimised manner by platformcode. Use a somewhat randomly generated set of inputs that is supposedto be representative, using the same set of divisors twice, expressed asa constant and as a variable each, so as to verify the implementationfor both cases should they be handled by different code execution paths.Reference results were produced with GNU bc.At the conclusion output the total execution time elapsed.Signed-off-by: Maciej W.

15d5761a - kbuild: introduce ccflags-remove-y and asflags-remove-y

Tue, 07 Jul 2020 09:21:16 +0000

kbuild: introduce ccflags-remove-y and asflags-remove-yCFLAGS_REMOVE_.o filters out flags when compiling a particularobject, but there is no convenient way to do that for every object ina directory.Add ccflags-remove-y and asflags-remove-y to make it easily.Use ccflags-remove-y to clean up some Makefiles.The add/remove order works as follows: [1] KBUILD_CFLAGS specifies compiler flags used globally [2] ccflags-y adds compiler flags for all objects in the current Makefile [3] ccflags-remove-y removes compiler flags for all objects in the current Makefile (New feature) [4] CFLAGS_ adds compiler flags per file. [5] CFLAGS_REMOVE_ removes compiler flags per file.Having [3] before [4] allows us to remove flags from most (but not all)objects in the current Makefile.For example, kernel/trace/Makefile removes $(CC_FLAGS_FTRACE)from all objects in the directory, then adds it back totrace_selftest_dynamic.o and CFLAGS_trace_kprobe_selftest.oThe same applies to lib/livepatch/Makefile.Please note ccflags-remove-y has no effect to the sub-directories.In contrast, the previous notation got rid of compiler flags also fromall the sub-directories.The following are not affected because they have no sub-directories: arch/arm/boot/compressed/ arch/powerpc/xmon/ arch/sh/ kernel/trace/However, lib/ has several sub-directories.To keep the behavior, I added ccflags-remove-y to all Makefilesin subdirectories of lib/, except the following: lib/vdso/Makefile - Kbuild does not descend into this Makefile lib/raid/test/Makefile - This is not used for the kernel buildI think commit 2464a609ded0 ("ftrace: do not trace library functions")excluded too much. In the next commit, I will remove ccflags-remove-yfrom the sub-directories of lib/.Suggested-by: Sami Tolvanen Signed-off-by: Masahiro Yamada Acked-by: Steven Rostedt (VMware) Acked-by: Michael Ellerman (powerpc)Acked-by: Brendan Higgins (KUnit)Tested-by: Anders Roxell List of files: /linux-6.15/lib/math/Makefile
