selftests/nolibc: add armthumb configurationWhile nolibc does support ARM Thumb instructions,that support was not tested specifically.Add a new test configuration for it.Tested-by: Willy Tarreau Link: https://lore.kernel.org/r/20250301-nolibc-armthumb-v1-2-d1f04abb5f6d@weissschuh.netSigned-off-by: Thomas Weißschuh List of files: /linux-6.15/tools/testing/selftests/nolibc/Makefile

9c812b01 - tools/nolibc: add support for 32-bit s390

Thu, 06 Feb 2025 07:10:27 +0000

tools/nolibc: add support for 32-bit s39032-bit s390 is very close to the existing 64-bit implementation.Some special handling is necessary as there is neither LLVM norQEMU support. Also the kernel itself can not build natively for 32-bits390, so instead the test program is executed with a 64-bit kernel.Acked-by: Willy Tarreau Link: https://lore.kernel.org/r/20250206-nolibc-s390-v2-2-991ad97e3d58@weissschuh.netSigned-off-by: Thomas Weißschuh List of files: /linux-6.15/tools/testing/selftests/nolibc/Makefile

3d1e67c6 - selftests/nolibc: rename s390 to s390x

Thu, 06 Feb 2025 07:10:26 +0000

selftests/nolibc: rename s390 to s390xSupport for 32-bit s390 is about to be added.As "s39032" would look horrible, use the another naming scheme.32-bit s390 is "s390" and 64-bit s390 is "s390x",similar to how it is handled in various toolchain components.Acked-by: Willy Tarreau Link: https://lore.kernel.org/r/20250206-nolibc-s390-v2-1-991ad97e3d58@weissschuh.netSigned-off-by: Thomas Weißschuh List of files: /linux-6.15/tools/testing/selftests/nolibc/Makefile

d7d271ec - selftests/nolibc: execute defconfig before other targets

Thu, 23 Jan 2025 07:37:40 +0000

selftests/nolibc: execute defconfig before other targetsSome targets use the test kernel configuration.Executing defconfig in the same make invocation as those targets resultsin errors as the configuration may be in an inconsistent state duringreconfiguration.Avoid this by introducing ordering dependencies between the defconfigand some other targets.Acked-by: Willy Tarreau Link: https://lore.kernel.org/r/20250123-nolibc-config-v2-4-5701c35995d6@weissschuh.netSigned-off-by: Thomas Weißschuh List of files: /linux-6.15/tools/testing/selftests/nolibc/Makefile

Thu, 23 Jan 2025 07:37:39 +0000

selftests/nolibc: drop call to mrproper target"mrproper" unnecessarily cleans a lot of files.kbuild is smart enough to handle changed configurations,so the cleanup is not necessary and only leads to excessive rebuilds.Acked-by: Willy Tarreau Link: https://lore.kernel.org/r/20250123-nolibc-config-v2-3-5701c35995d6@weissschuh.netSigned-off-by: Thomas Weißschuh List of files: /linux-6.15/tools/testing/selftests/nolibc/Makefile

selftests/nolibc: start qemu with 1 GiB of memoryRecently the loongarch defconfig stopped working with the default 128 MiBof memory. The VM just spins infinitively.Increasing the available memory to 1 GiB, similar to s390, fixes theissue.

selftests/nolibc: use correct clang target for s390/systemzThe target names between GCC and clang differ for s390.While GCC uses "s390", clang uses "systemz".This mapping is not handled by tools/scripts/Makefile.include,so do it in the nolibc-test Makefile.Acked-by: Willy Tarreau Reviewed-by: Shuah Khan Link: https://lore.kernel.org/r/20240807-nolibc-llvm-v2-14-c20f2f5fc7c2@weissschuh.netSigned-off-by: Thomas Weißschuh List of files: /linux-6.15/tools/testing/selftests/nolibc/Makefile
