[PATCH v4 00/18] tools/nolibc: shrink arch support

by Zhangjin Wu

Hi, Willy, Thomas Thanks very much for your careful review and great suggestions, now, we get v4 revision of the arch shrink series [1], it mainly include a new fixup for -O0 under gcc < 11.1.0, the stackprotector support for _start_c(), new testcases for startup code and two new test targets. All of the tests passed or skipped (tinyconfig + few options + qemu-system) for both -Os and -O0: arch/board | result ------------|------------ arm/versatilepb | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning. arm/vexpress-a9 | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning. arm/virt | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning. aarch64/virt | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning. i386/pc | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning. x86_64/pc | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning. mipsel/malta | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning. loongarch64/virt | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning. riscv64/virt | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning. s390x/s390-ccw-virtio | 165 test(s): 158 passed, 7 skipped, 0 failed => status: warning.

Hope you like this revisoin ;-) Next patchset is powerpc & powerpc64 support, after that we will send the v2 of tinyconfig support, at last the left rv32 patches (mainly 64bit time).

[PATCH v5 0/4] RISC-V: mm: Make SV48 the default address space

by Charlie Jenkins

Make sv48 the default address space for mmap as some applications currently depend on this assumption. Users can now select a desired address space using a non-zero hint address to mmap. Previously, requesting the default address space from mmap by passing zero as the hint address would result in using the largest address space possible. Some applications depend on empty bits in the virtual address space, like Go and Java, so this patch provides more flexibility for application developers. -Charlie --- v5: - Minor wording change in documentation - Change some parenthesis in arch_get_mmap_ macros - Added case for addr==0 in arch_get_mmap_ because without this, programs would crash if RLIMIT_STACK was modified before executing the program. This was tested using the libhugetlbfs tests. v4: - Split testcases/document patch into test cases, in-code documentation, and formal documentation patches - Modified the mmap_base macro to be more legible and better represent memory layout - Fixed documentation to better reflect the implmentation - Renamed DEFAULT_VA_BITS to MMAP_VA_BITS - Added additional test case for rlimit changes --- Charlie Jenkins (4): RISC-V: mm: Restrict address space for sv39,sv48,sv57 RISC-V: mm: Add tests for RISC-V mm RISC-V: mm: Update pgtable comment documentation RISC-V: mm: Document mmap changes Documentation/riscv/vm-layout.rst | 22 +++ arch/riscv/include/asm/elf.h | 2 +- arch/riscv/include/asm/pgtable.h | 20 ++- arch/riscv/include/asm/processor.h | 46 +++++- tools/testing/selftests/riscv/Makefile | 2 +- tools/testing/selftests/riscv/mm/.gitignore | 1 + tools/testing/selftests/riscv/mm/Makefile | 21 +++ .../selftests/riscv/mm/testcases/mmap.c | 133 ++++++++++++++++++ 8 files changed, 234 insertions(+), 13 deletions(-) create mode 100644 tools/testing/selftests/riscv/mm/.gitignore create mode 100644 tools/testing/selftests/riscv/mm/Makefile create mode 100644 tools/testing/selftests/riscv/mm/testcases/mmap.c -- 2.41.0

[PATCH net-next 0/4] selftests: mptcp: join: pass args in new env vars

by Matthieu Baerts

In this series, Geliang did some refactoring in the mptcp_join.sh file. Patch 1 reduces the scope of some global env vars, only used by some tests: easier to deal with. Patch 2 uses a dedicated env var for fastclose case instead of re-using addr_nr_ns2 with embedded info, clearer. Patch 3 is similar but for the fullmesh case. Patch 4 moves a positional but optional argument of run_tests() to an env var like it has already been done with the other args, cleaner.

[PATCH RFC 0/2] Add support for inlined documentation for kunit and kselftests

by Mauro Carvalho Chehab

This RFC is a follow-up of the discussions taken here: https://lore.kernel.org/linux-doc/20230704132812.02ba97ba@maurocar-mobl2/T/… It adds a new extension that allows documenting tests using the same tool we're using for DRM unit tests at IGT GPU tools: https://gitlab.freedesktop.org/drm/igt-gpu-tools. While kernel-doc has provided documentation for in-lined functions/struct comments, it was not meant to document tests. Tests need to be grouped by the test functions. It should also be possible to produce other outputs from the documentation, to integrate it with test suites. For instance, Internally at Intel, we use the comments to generate DOT files hierarchically grouped per feature categories. This is just an initial RFC to start discussions around the solution. Before being merged upstream, we need to define what tags will be used to identify test markups and add a simple change at kernel-doc to let it ignore such markups. On this series, we have: - patch 1: adding test_list.py as present at the IGT tree, after a patch series to make it more generic: https://patchwork.freedesktop.org/series/120622/ - patch 2: adds an example about how tests could be documented. This is a really simple example, just to test the feature, specially designed to make easy to build just the test documentation from a single DRM kunit file. After discussions, my plan is to send a new version addressing the issues, and add some documentation for DRM and/or i915 kunit tests.
