Subject: [PATCH 0/6] System call table generation support
Date: Mon, 16 Jul 2018 15:53:52 +0530 [thread overview]
Message-ID: <1531736638-15294-1-git-send-email-firoz.khan@linaro.org> (raw)
The goal of this patch series is to easily add/modify/delete a
system call by changing entry in syscall.tbl file. No need
to manually edit many files.
The another goal of this patch series is to to unify the system
call implementation across all the architectures. ARM, s390 and
x86 architecuture does have the similar support. I leverage their
implementation to come up with a generic solution.
I have done the same support for work for ia64, m68k, microblaze,
mips, parisc, powerpc, sh, sparc, and xtensa. But I started sending
the patch for one architecuture for review. Below mentioned git
repository contains more details.
Git repo:- https://github.com/frzkhn/system_call_table_generator/
Finally, this is the ground work for solving the Y2038 issue. We
need to change two dozen of system calls to solve Y2038 issue. So
this implementation will help to easily modify from existing system
call to Y2038 compatible system calls.
