29c5c3ac - arch: syscalls: remove $(srctree)/ prefix from syscall tables

Mon, 15 Feb 2021 00:48:23 +0000

arch: syscalls: remove $(srctree)/ prefix from syscall tablesThe 'syscall' variables are not directly used in the commands.Remove the $(srctree)/ prefix because we can rely on VPATH.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/powerpc/kernel/syscalls/Makefile

865fa29f - arch: syscalls: add missing FORCE and fix 'targets' to make if_changed work

Mon, 15 Feb 2021 00:48:22 +0000

arch: syscalls: add missing FORCE and fix 'targets' to make if_changed workThe rules in these Makefiles cannot detect the command line changebecause the prerequisite 'FORCE' is missing.Adding 'FORCE' will result in the headers being rebuilt every timebecause the 'targets' additions are also wrong; the file paths in'targets' must be relative to the current Makefile.Fix all of them so the if_changed rules work correctly.Signed-off-by: Masahiro Yamada Acked-by: Geert Uytterhoeven List of files: /linux-6.15/arch/powerpc/kernel/syscalls/Makefile

aff85039 - powerpc: add system call table generation support

Mon, 17 Dec 2018 10:40:34 +0000

powerpc: add system call table generation supportThe system call tables are in different format in allarchitecture and it will be difficult to manually add ormodify the system calls in the respective files. To makeit easy by keeping a script and which will generate theuapi header and syscall table file. This change will alsohelp to unify the implementation across all architectures.The system call table generation script is added insyscalls directory which contain the script to generateboth uapi header file and system call table files.The syscall.tbl file will be the input for the scripts.syscall.tbl contains the list of available system callsalong with system call number and corresponding entry point.Add a new system call in this architecture will be possibleby adding new entry in the syscall.tbl file.Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. - Compat entry name, if required.syscallhdr.sh and syscalltbl.sh will generate uapi header-unistd_32/64.h and syscall_table_32/64/c32/spu.h filesrespectively. File syscall_table_32/64/c32/spu.h is incl-uded by syscall.S - the real system call table. Both *.shfiles will parse the content syscall.tbl to generate theheader and table files.ARM, s390 and x86 architecuture does have similar support.I leverage their implementation to come up with a genericsolution.Signed-off-by: Firoz Khan Signed-off-by: Michael Ellerman List of files: /linux-6.15/arch/powerpc/kernel/syscalls/Makefile
