linux.git/arch/nios2/kernel/syscall_table.c, branch v7.1 Linux kernel source tree nios2: implement architecture-specific portion of sys_clone3 2025-09-01T13:31:34+00:00 Simon Schuster schuster.simon@siemens-energy.com 2025-09-01T13:09:53+00:00 c6ac444ff20ce301020a41e35f1942c6524e0864 This commit adds the sys_clone3 entry point for nios2. An architecture-specific wrapper (__sys_clone3) is required to save and restore additional registers to the kernel stack via SAVE_SWITCH_STACK and RESTORE_SWITCH_STACK.

nios2: convert to generic syscall table 2024-07-10T12:23:38+00:00 Arnd Bergmann arnd@arndb.de 2024-04-23T15:52:56+00:00 ef608c5767f983123b7d7f18b1b940e934419a3c The uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now be generated from scripts/syscall.tbl, which makes this consistent with the other architectures that have their own syscall.tbl. nios2 has one extra system call that gets added to scripts/syscall.tbl. The time32, stat64, and rlimit entries in the syscall_abis_32 line are for system calls that were part of the generic ABI when arch/nios2 got added but are no longer enabled by default for new architectures. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this. Signed-off-by: Arnd Bergmann <arnd@arndb.de> 
The uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now be

nios2 has one extra system call that gets added to scripts/syscall.tbl.

The time32, stat64, and rlimit entries in the syscall_abis_32
line are for system calls that were part of the generic ABI when
arch/nios2 got added but are no longer enabled by default for new
architectures.

Both the user visible side of asm/unistd.h and the internal syscall
table in the kernel should have the same effective contents after this.
