selftests: complete kselftest include centralization

2025-11-27T22:24:31Z

This follow-up patch completes centralization of kselftest.h and ksefltest_harness.h includes in remaining seltests files, replacing all relative paths with a non-relative paths using shared -I include path in lib.mk Tested with gcc-13.3 and clang-18.1, and cross-compiled successfully on riscv, arm64, x86_64 and powerpc arch.

selftests: riscv: Fix vector tests

2025-01-18T20:33:37Z

Overhaul the riscv vector tests to use kselftest_harness to help the test cases correctly report the results and decouple the individual test cases from each other. With this refactoring, only run the test cases if vector is reported and properly report the test case as skipped otherwise. The v_initval_nolibc test was previously not checking if vector was supported and used a function (malloc) which invalidates the state of the vector registers.

selftest: run vector prctl test for ZVE32X

2024-05-30T21:33:11Z

The minimal requirement for running Vector subextension on Linux is ZVE32X. So change the test accordingly to run prctl as long as it find it. Signed-off-by: Andy Chiu Link: https://lore.kernel.org/r/20240510-zve-detection-v5-8-0711bdd26c12@sifive.com Signed-off-by: Palmer Dabbelt

Merge patch series "tools: selftests: riscv: Fix compiler warnings"

2024-01-11T16:02:55Z

Christoph Muellner says: From: Christoph Müllner When building the RISC-V selftests with a riscv32 compiler I ran into a couple of compiler warnings. While riscv32 support for these tests is questionable, the fixes are so trivial that it is probably best to simply apply them. Note that the missing-include patch and some format string warnings are also relevant for riscv64. * b4-shazam-merge: tools: selftests: riscv: Fix compile warnings in mm tests tools: selftests: riscv: Fix compile warnings in vector tests tools: selftests: riscv: Add missing include for vector test tools: selftests: riscv: Fix compile warnings in cbo tools: selftests: riscv: Fix compile warnings in hwprobe Link: https://lore.kernel.org/r/20231123185821.2272504-1-christoph.muellner@vrull.eu Signed-off-by: Palmer Dabbelt

RISC-V: hwprobe: Clarify cpus size parameter

2024-01-03T11:36:47Z

The "count" parameter associated with the 'cpus' parameter of the hwprobe syscall is the size in bytes of 'cpus'. Naming it 'cpu_count' may mislead users (it did me) to think it's the number of CPUs that are or can be represented by 'cpus' instead. This is particularly easy (IMO) to get wrong since 'cpus' is documented to be defined by CPU_SET(3) and CPU_SET(3) also documents a CPU_COUNT() (the number of CPUs in set) macro. CPU_SET(3) refers to the size of cpu sets with 'setsize'. Adopt 'cpusetsize' for the hwprobe parameter and specifically state it is in bytes in Documentation/riscv/hwprobe.rst to clarify.
