[PATCH v5 0/5] nolibc: add part2 of support for rv32

by Zhangjin Wu

Hi, Willy This is the revision of the v4 part2 of support for rv32 [1], this further split the generic KARCH code out of the old rv32 compile patch and also add kernel specific KARCH and nolibc specific NARCH for tools/include/nolibc/Makefile too. This is rebased on the dev.2023.06.14a branch of linux-rcu repo [2] with basic run-user and run tests. Changes from v4 -> v5: * selftests/nolibc: allow customize kernel specific ARCH variable The KARCH customize support part splitted out of the old rv32 compile patch and removed the one passed to tools/include/nolibc/Makefile. * tools/nolibc: add kernel and nolibc specific ARCH variables Pass original ARCH to tools/include/nolibc/Makefile, add KARCH and NARCH for kernel and nolibc respectively. * selftests/nolibc: riscv: customize makefile for rv32 Now, it is rv32 specific, no generic code.

[PATCH v1 00/11] tools/nolibc: shrink arch support

by Zhangjin Wu

Hi, This patchset further improves porting of nolibc to new architectures, it is based on our previous v5 sysret helper series [1]. It mainly shrinks the assembly _start by moving most of its operations to a C version of _start_c() function. and also, it removes the old sys_stat() support by using the sys_statx() instead and therefore, removes all of the arch specific sys_stat_struct. Tested 'run' on all of the supported architectures: arch/board | result ------------|------------ arm/vexpress-a9 | 141 test(s) passed, 1 skipped, 0 failed. See all results in /labs/linux-lab/logging/nolibc/arm-vexpress-a9-nolibc-test.log arm/virt | 141 test(s) passed, 1 skipped, 0 failed.

Changes: * tools/nolibc: remove old arch specific stat support Just like the __NR_statx we used in nolibc-test.c, Let's only reserve sys_statx() and use it to implement the stat() function. Remove the old sys_stat() and sys_stat_struct completely. * tools/nolibc: add new crt.h with _start_c A new C version of _start_c() is added to only require a 'sp' argument and find the others (argc, argv, envp/environ, auxv) for us in C. * tools/nolibc: include crt.h before arch.h Include crt.h before arch.h to let _start() be able to call the new added _start_c() in arch-<ARCH>.h. * tools/nolibc: arm: shrink _start with _start_c tools/nolibc: aarch64: shrink _start with _start_c tools/nolibc: i386: shrink _start with _start_c tools/nolibc: x86_64: shrink _start with _start_c tools/nolibc: mips: shrink _start with _start_c tools/nolibc: loongarch: shrink _start with _start_c tools/nolibc: riscv: shrink _start with _start_c tools/nolibc: s390: shrink _start with _start_c Move most of the operations from the assembly _start() to the C _start_c(), only require to do minimal operations in assembly _start now. With this patchset, porting nolibc to a new architecture become easier, the powerpc porting will be added later.

[PATCH v1] Fix documentation of panic_on_warn

The kernel cmdline option panic_on_warn expects an integer, it is not a plain option as documented. A number of uses in the tree figured this already, and use panic_on_warn=1 for their purpose.

[PATCH v4 00/10] tools/nolibc: add a new syscall helper

by Zhangjin Wu

Hi, Thomas, David, Willy Thanks very much for your kindly review. This is the revision of v3 "tools/nolibc: add a new syscall helper" [1], this mainly applies the suggestion from David in this reply [2] and rebased everything on the dev.2023.06.14a branch of linux-rcu [3]. The old __sysret() doesn't support the syscalls with pointer return value, this revision now supports such syscalls. The left mmap() syscall is converted to use this new __sysret() with additional test cases. Changes from v3 -> v4: * tools/nolibc: sys.h: add a syscall return helper tools/nolibc: unistd.h: apply __sysret() helper tools/nolibc: sys.h: apply __sysret() helper The original v3 series, no code change, except the Reviewed-by lines from Thomas. * tools/nolibc: unistd.h: reorder the syscall macros reorder the syscall macros in using order and align most of them. * tools/nolibc: add missing my_syscall6() for mips required by mmap() syscall, this is the last missing my_syscall6(). * tools/nolibc: __sysret: support syscalls who return a pointer Apply suggestion from David. Let __sysret() also supports syscalls with pointer return value, so, the return value is converted to unsigned long and the comparing of < 0 is converted to the comparing of [(unsigned long)-MAX_ERRNO, (unsigned long)-1]. This also allows return a huge value (not pointer) with highest bit as 1. It is able to merge this one to the first one if necessary. * tools/nolibc: clean up mmap() support Apply new __sysret(), clean up #ifdef and some macros. * selftests/nolibc: add EXPECT_PTREQ, EXPECT_PTRNE and EXPECT_PTRER selftests/nolibc: add sbrk_0 to test current brk getting selftests/nolibc: add mmap and munmap test cases Add some mmap & munmap test cases and the corresponding helpers, to verify one of the new helpers, a sbrk_0 test case is also added.
