The system call tables are in different format in all architecture and it will be difficult to manually add or modify the system calls in the respective files. To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implementation across all architectures.
The system call table generation script is added in syscalls directory which contain the script to generate both 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 calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by 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.h files respect- ively. File syscall_table_32/64/c32.h is included by sys- call.S - the real system call table. Both .sh files will parse the content syscall.tbl to generate the header and table files.
ARM, s390 and x86 architecuture does have the similar support. I leverage their implementation to come up with a generic solution.
