[PATCH 2/2] asinfo: Introduce static query tool asinfo

Fri Jul 28 15:33:54 UTC 2017
From: Edgar Kaziakhmedov <edgar.kaziakhmedov at virtuzzo.com>
The 1.2 version of asinfo tool. The asinfo tool has the
following architecture:
commnand dispatcher->architecture dispatcher->abi dispatcher->
system call dispatcher->filter dispatcher
As for arch. dispatcher, the asinfo has get-arch, list-arch, set-arch
%name_of_arch options, arch_dispatcher is purposed to process them.
As for abi dispatcher, the asinfo has get-abi, list-abi, set-abi
%name_of_abi options, abi_dispatcher is putposed to process it.
As for command_dispatcher, for now it checks all options for
correctness.
Now, to find out the main principle of working, let’s consider next
one case:
$ asinfo get-arch
Firstly, arch_dispatcher will return the current architecture, based on
uname return value, after that in case of no options for abi_dispatcher,
AD perceives it as get-abi option and returns corresponding for the set
arch value.
NOTE: syscall_dispatcher for now is not supported
It is worth mentioning that this tool supports almostly all
architectures supporting by Linux kernel.
* Makefile.am (SUBDIRS): Add tools directory.
* configure.ac (AC_CONFIG_FILES): Add Makefile's.
* tools/Makefile.am: New file.
* tools/asinfo/Makefile.am: New file.
* tools/asinfo/dispatchers.h: New file. Prototype abi_dispatcher,
arch_dispatcher, and syscall_dispatcher.
* tools/asinfo/dispatchers.c: New file. Implement it.
* tools/asinfo/arch_interface.h: New file. Prototype methods to simplify
work with the list of arch_descriptor. Introduce struct arch_descriptor.
* tools/asinfo/arch_interface.c: New file. Implement it.
* tools/asinfo/request_msgs.h: New file. Introduce main types of requests.
Introduce structures for syscall_dispatcher.
* tools/asinfo/asinfo.c: New file. Implement support of all options.
* tools/asinfo/asinfo.1: New file. Empty man.
