Subject: [PATCH v6 00/15] tools/nolibc: add a new syscall helper
Date: Fri, 7 Jul 2023 22:49:28 +0800 [thread overview]
Message-ID: <cover.1688739492.git.falcon@tinylab.org> (raw)
Hi, Willy
Here is the v6 of the __sysret series [1], applies your suggestions.
additionally, the sbrk() also uses the __sysret helper.
These patches are tested (together with the coming v4 selftests/nolibc
patches) for all of the supported architectures:
arch/board | result
------------|------------
arm/vexpress-a9 | 142 test(s) passed, 1 skipped, 0 failed.
arm/virt | 142 test(s) passed, 1 skipped, 0 failed.
aarch64/virt | 142 test(s) passed, 1 skipped, 0 failed.
ppc/g3beige | not supported
ppc/ppce500 | not supported
i386/pc | 142 test(s) passed, 1 skipped, 0 failed.
x86_64/pc | 142 test(s) passed, 1 skipped, 0 failed.
mipsel/malta | 142 test(s) passed, 1 skipped, 0 failed.
loongarch64/virt | 142 test(s) passed, 1 skipped, 0 failed.
riscv64/virt | 142 test(s) passed, 1 skipped, 0 failed.
riscv32/virt | 0 test(s) passed, 0 skipped, 0 failed.
s390x/s390-ccw-virtio | 142 test(s) passed, 1 skipped, 0 failed.
Changes from v5 --> v6:
* tools/nolibc: arch-*.h: fix up code indent errors
toolc/nolibc: arch-*.h: clean up whitespaces after __asm__
Fix up the code indent errors and whitespaces between __asm__ and volatile.
The post-whitespaces are reserved as before.
* tools/nolibc: arch-loongarch.h: shrink with _NOLIBC_SYSCALL_CLOBBERLIST
tools/nolibc: arch-mips.h: shrink with _NOLIBC_SYSCALL_CLOBBERLIST
Add _NOLIBC_ prefix for SYSCALL_CLOBBERLIST.
* tools/nolibc: add missing my_syscall6() for mips
Use post-whitespaces instead of post-tab.
The above 4 patches are preparation for this one.
* tools/nolibc: __sysret: support syscalls who return a pointer
Add comments about the new errno range [-MAX_ERRNOR, -1], add ref to
the musl and glibc.
* tools/nolibc: clean up mmap() routine
Comment the MAP_FAILED return info.
* tools/nolibc: clean up sbrk() routine
New patch, applies __sysret() helper too and also fixes up an error
reported by scripts/checkpatch.pl.
* selftests/nolibc: export argv0 for some tests
selftests/nolibc: prepare: create /dev/zero
Prepare /dev/zero and argv0 for mmap test cases.
* selftests/nolibc: add EXPECT_PTREQ, EXPECT_PTRNE and EXPECT_PTRER
selftests/nolibc: add sbrk_0 to test current brk getting
No change.
* selftests/nolibc: add mmap_bad test case
selftests/nolibc: add munmap_bad test case
selftests/nolibc: add mmap_munmap_good test case
Split the first two out to standalone patches.
Add /dev/zero and argv0 to the file list and assigns a file_size
manually for /dev/zero.
Best regards,
Zhangjin
