[PATCH 2/3] sh: Added system call table generation support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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'll generate the
header file and syscall table file so this change will
unify them across all architectures.

The system call table generation script is added in
syscalls directory which contain the script to generate
both uapi header file system call table generation file
and syscall.tbl file which'll 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.

syscallhdr.sh and syscalltbl.sh will generate uapi header-
unistd.h and syscall_table.h files respectively. File
syscall_table.h is included by syscall.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. And this is the ground work for y2038 issue. We need
to change 52 system call implementation and this work will
reduce the effort by simply modify 52 entries in syscall.tbl.
