[PATCH v5 0/7] mips: system call table generation support

[PATCH v5 0/7] mips: system call table generation support

[Firoz Khan]

The purpose of this patch series is, we can easily
add/modify/delete system call table support by cha-
nging entry in syscall.tbl file instead of manually
changing many files. The other goal is to unify the 
system call table generation support implementation 
across all the architectures. 

The system call tables are in different format in 
all architecture. It will be difficult to manually
add, modify or delete the system calls in the resp-
ective files manually. To make it easy by keeping a 
script and which'll generate uapi header file and 
syscall table file.

syscall.tbl contains the list of available system 
calls along with system call number and correspond-
ing entry point. Add a new system call in this arch-
itecture 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.

ARM, s390 and x86 architecuture does exist the sim-
ilar support. I leverage their implementation to 
come up with a generic solution.

I have done the same support for work for alpha, 
ia64, m68k, microblaze, parisc, powerpc, sh, sparc, 
and xtensa. Below mentioned git repository contains
more details about the workflow.

https://github.com/frzkhn/system_call_table_generator/

Finally, this is the ground work to solve the Y2038
issue. We need to add two dozen of system calls to 
solve Y2038 issue. So this patch series will help to
add new system calls easily by adding new entry in
the syscall.tbl.

Changes since v4:
 - _MIPS_SIM_ABIN64 (suppose to be _MIPS_SIM_NABI64)
   macro rename back to _MIPS_SIM_ABI64 to avoid
   toolchain issue. 

Changes since v3:
 - rearranged the patches for '64' to 'n64' conver-
   sion.
 - moved the unistd_nr_*.h files to asm/unistd.h
 - modified the *.sh files.

Changes since v2:
 - fixed __NR_syscalls assign issue.

Changes since v1:
 - optimized/updated the syscall table generation 
   scripts.
 - fixed all mixed indentation issues in syscall.tbl.
 - added "comments" in syscall_*.tbl.
 - changed from generic-y to generated-y in Kbuild.

[PATCH v5 1/7] mips: add __NR_syscalls along with __NR_Linux_syscalls

[Firoz Khan]

__NR_Linux_syscalls macro holds the number of system call
exist in mips architecture. We have to change the value of
__NR_Linux_syscalls, if we add or delete a system call.

One of the patch in this patch series has a script which
will generate a uapi header based on syscall.tbl file.
The syscall.tbl file contains the total number of system
calls information. So we have two option to update __NR-
_Linux_syscalls value.

1. Update __NR_Linux_syscalls in asm/unistd.h manually
   by counting the no.of system calls. No need to update
   __NR_Linux_syscalls until we either add a new system
   call or delete existing system call.

2. We can keep this feature it above mentioned script,
   that will count the number of syscalls and keep it in
   a generated file. In this case we don't need to expli-
   citly update __NR_Linux_syscalls in asm/unistd.h file.

The 2nd option will be the recommended one. For that, I
added the __NR_syscalls macro in uapi/asm/unistd.h along
with __NR_Linux_syscalls. The macro __NR_syscalls also
added for making the name convention same across all
architecture. While __NR_syscalls isn't strictly part of
the uapi, having it as part of the generated header to
simplifies the implementation. We also need to enclose
this macro with #ifdef __KERNEL__ to avoid side effects.

[PATCH v5 2/7] mips: remove unused macros

[Firoz Khan]

Remove NR_syscalls from asm/unistd.h as there is no
users to use NR_syscalls macro in mips kernel.

Remove __NR_Linux_syscalls from uapi/asm/unistd.h as
there is no users to use NR_syscalls macro in mips
kernel.

MAX_SYSCALL_NO can also remove as there is commit
2957c9e61ee9 ("[MIPS] IRIX: Goodbye and thanks for
all the fish"), eight years ago.

[PATCH v5 3/7] mips: rename macros and files from '64' to 'n64'

[Firoz Khan]

When we get nanoMIPS support we'll be introducing the p32
ABI, and there's a reasonable chance that the equivalent
p64 ABI may come along in the future. Using 'n64' now would
avoid confusion in that case where we may have 2 different
64-bit ABIs.

[PATCH v5 4/7] mips: add +1 to __NR_syscalls in uapi header

[Firoz Khan]

All other architectures are hold a value for __NR_syscalls will
be equal to the last system call number +1.

But in mips architecture, __NR_syscalls hold the value equal to
total number of system exits in the architecture. One of the
patch in this patch series will genarate uapi header files.

In order to make the implementation common across all architect-
ures, add +1 to __NR_syscalls, which will be equal to the last
system call number +1.

[PATCH v5 5/7] mips: remove syscall table entries

[Firoz Khan]

The config flag - CONFIG_MIPS_MT_FPAFF uses to check whether which
syscall entries need to be used in scall32-o32.S file.

One of the patch in this patch series will generate syscall table
file. But CONFIG_MIPS_MT_FPAFF flag will add more complexity in the
script to generate the syscall table file.

In order to come up with a common implementation across all archit-
ecture, we need to remove mipsmt_sys_sched_setaffinity and mipsmt-
_sys_sched_getaffinity from the table and define it in other way.

[PATCH v5 6/7] mips: add system call table generation support

[Firoz Khan]

The system call tables are in different format in all
architecture and it will be difficult to manually add,
modify or delete the syscall table entries in the res-
pective 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 implemen-
tation across all architectures.

The system call table generation script is added in
kernel/syscalls directory which contain the scripts to
generate both uapi header file and system call table
files. The syscall.tbl will be 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, syscallnr.sh and syscalltbl.sh will gene-
rate uapi header unistd_n64/n32/o32.h, unistd_nr_n64/n32/-
o32.h and syscall_table_32_o32/64_n64/64-n32/64-o32.h files
respectively. All *.sh files will parse the content sys-
call.tbl to generate the header and table files. unistd-
_n64/n32/o32.h and unistd_nr_n64/n32/o32.h will be included
by uapi/asm/unistd.h and syscall_table_32_o32/64_n64/64-n32-
/64-o32.h is included by kernel/syscall_table32_o32/64-
_n64/64-n32/64-o32.S - the real system call table.

ARM, s390 and x86 architecuture does have similar support.
I leverage their implementation to come up with a generic
solution.

[PATCH v5 7/7] mips: generate uapi header and system call table files

[Firoz Khan]

System call table generation script must be run to gener-
ate unistd_(nr_)n64/n32/o32.h and syscall_table_32_o32/
64_n64/64_n32/64-o32.h files. This patch will have changes
which will invokes the script.

This patch will generate unistd_(nr_)n64/n32/o32.h and
syscall_table_32_o32/64_n64/64-n32/64-o32.h files by the
syscall table generation script invoked by parisc/Make-
file and the generated files against the removed files
must be identical.

The generated uapi header file will be included in uapi/-
asm/unistd.h and generated system call table header file
will be included by kernel/scall32-o32/64-n64/64-n32/-
64-o32.Sfile.
