I've pushed a tag named 20230815-for-6.6-2 in the repo below: https://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/nolibc.git Please let me know if you want me to resend a PR. I'm also attaching a script I'm using here to run the tests on the various archs. It's quite limited but gets the job done for now. There are simplifications coming for future versions. The simplest way to use it is: 1) make sure you have the relevant toolchains. We're currently using those Arnd maintains and that are located here: https://mirrors.edge.kernel.org/pub/tools/crosstool/ If that helps I'm attaching a tiny script I have which downloads all needed ones from a given version and extracts them in a same directory. Please note, if you've downloaded version 13.1.0, I've had a segfault on gcc-aarch64 only on this one and that was fixed with 13.2.0. I preferred to tell you upfront instead of wasting your time on it. 2) from the kernel top dir, copy the test-all-full4.sh script into tools/testing/selftests/nolibc/ then indicate where you extracted the crosstools: $ cd tools/testing/selftests/nolibc $ TOOLCHAIN_BASE=/path/to/gcc-13.2.0-nolibc ./test-all-full4.sh For each supported arch, it will build the test program, run it in userland under qemu with your current kernel, and will also build a kernel, install the program in it and run it under qemu. Support for loongarch in Qemu is recent, so if the one from your distro doesn't have it, you can instead build for all other archs by passing their names in argument to the program: $ TOOLCHAIN_BASE=... ./test-all-full4.sh \ i386 x86_64 arm64 arm mips ppc ppc64 ppc64le riscv s390 Note that the archs most of the time match the kernel ones, except when there are variants, where we defined extra ones (typically to force 32/64 bits), and in this case we use distinct names to avoid any ambiguity. This explains "ppc" and "ppc64" above, which both map to "powerpc" when building the kernel. 3) At the end it will show a synthetic report indicating what archs succeeded/failed and some will show "warning" if there is at least one test skipped: #### Synthetic summary: USER i386 160 test(s): 158 passed, 2 skipped, 0 failed => status: warning KERN i386 160 test(s): 160 passed, 0 skipped, 0 failed => status: success Two "skipped" are expected for the userland tests, due to privileged operations being skipped. That is OK. On MIPS and s390 depending on the toolchains, another skipped can appear due to the stack-protector test being skipped. In this case it will be 3 skipped for userland, and 1 skipped for the kernel. There should never be any failure. 4) Save precious time: it is often useful to just run the userland tests when you're not testing for a kernel regression: the program is exactly the same and if you didn't change your kernel between tests there is no reason you'll get a different result once you know what the userland reports. For this, set USER_ONLY=1 when calling the script: $ TOOLCHAIN_BASE=... ./test-all-full4.sh \ USER_ONLY=1 \ i386 x86_64 arm64 arm mips ppc ppc64 ppc64le riscv s390 It will skip all the kernel parts and will only install UAPI headers, build nolibc-test for each arch and run it through Qemu. Quite honestly this is the recommended way to use it when you're not seeking a specific kernel issue. On my laptop it takes 24 seconds (loongarch was not tested here): #### Synthetic summary: USER i386 160 test(s): 158 passed, 2 skipped, 0 failed => status: warning USER x86_64 160 test(s): 158 passed, 2 skipped, 0 failed => status: warning USER arm64 160 test(s): 158 passed, 2 skipped, 0 failed => status: warning USER arm 160 test(s): 158 passed, 2 skipped, 0 failed => status: warning USER mips 160 test(s): 157 passed, 3 skipped, 0 failed => status: warning USER ppc 160 test(s): 158 passed, 2 skipped, 0 failed => status: warning USER ppc64 160 test(s): 158 passed, 2 skipped, 0 failed => status: warning USER ppc64le 160 test(s): 158 passed, 2 skipped, 0 failed => status: warning USER riscv 160 test(s): 158 passed, 2 skipped, 0 failed => status: warning USER s390 160 test(s): 157 passed, 3 skipped, 0 failed => status: warning 5) Other variables: it's possible to force a specific cross-compiler prefix with CROSS_COMPILE_$arch, or when building for a single arch, CROSS_COMPILE, a specific CC with CC, and to enable verbose build with V=1. 6) A complete capture of all outputs is done in "report.out", and a copy of each used nolibc-test executable is kept with the suffix -$arch. The script contains a "set -e" statement to stop on any error. There is one known case (missing qemu binary for userlan) where the error is ignored in the makefile and the build will continue. But this stuff is currently being improved so I consider there's no point re-changing this at the last minute at the risk of breaking other stuff. Do not hesitate to ask if you encounter difficulties or if anything is not clear. Thank you! Willy

Thank you. https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/log/?h=nolibc I will run tests later on today and keep you updated. thanks, -- Shuah
Hi Shuah, hi Paul, I'm sending you the list of planned nolibc changes for 6.6. A doc update may possibly follow a bit later to try to document the contribution process. We also noticed a slight increase in binary sizes that might be fixed soon but I wouldn't bet on this since it will require lot of testing again and I'd rather postpone this by default. In any case I have no intent to push any significant updates/fixes for 6.6 at this point. I'm also pasting a summary of the changes in this pull request, feel free to use it for the merge commit message if you need. For any question or if anything is not clear, do not hesitate to ask! Thanks, Willy ----- changes ------ Nolibc: - improved portability by removing build errors with -ENOSYS - added syscall6() on MIPS to support pselect6() and mmap() - added setvbuf(), rmdir(), pipe(), pipe2() - add support for ppc/ppc64 - environ is no longer optional - fixed frame pointer issues at -O0 - dropped sys_stat() in favor of sys_statx() - centralized _start_c() to remove lots of asm code - switched size_t to __SIZE_TYPE__ Selftests: - improved status reporting (success/warning/failure counts, path to log file) - various code cleanups (indent, unused variables, ...) - more consistent test numbering - enabled compiler warnings - dropped unreliable chmod_net test - improved reliability (create /dev/zero & /tmp, rely less on /proc) - new tests (brk/sbrk/mmap/munmap) - improved compatibility with musl - new run-nolibc-test target to build and run natively - new run-libc-test target to build and run against native libc - made the cmdline parser more reliable against boolean arguments - dropped dependency on memfd for vfprintf() test - nolibc-test is no longer stripped - added support for extending ARCH via XARCH Other: - add Thomas as co-maintainer ----------- The
