    Subject[RFCv3 20/21] tcm: Add Kbuild and Kconfig for drivers/target and Documentation/target/
    Date
    From: Nicholas Bellinger <nab@linux-iscsi.org>

    Add TCM Kbuild and Kconfig files and update drivers/ to pick up drivers/target.
    Add Docmentation/target/ for tcm_mod_builder.py script for generating new
    TCM v4 fabric modules functional ConfigFS skeletons.

    +>>>>>>>>>> The TCM v4 fabric module script generator <<<<<<<<<<
    +
    +Greetings all,
    +
    +This document is intended to be a mini-HOWTO for using the tcm_mod_builder.py
    +script to generate a brand new functional TCM v4 fabric .ko module of your very own,
    +that once built can be immediately be loaded to start access the new TCM/ConfigFS
    +fabric skeleton, by simplying using:
    +
    + modprobe $TCM_NEW_MOD
    + mkdir -p /sys/kernel/config/target/$TCM_NEW_MOD
    +
    +This script will create a new drivers/target/$TCM_NEW_MOD/, and will do the following
    +
    + *) Generate new API callers for drivers/target/target_core_fabric_configs.c logic
    + ->make_nodeacl(), ->drop_nodeacl(), ->make_tpg(), ->drop_tpg()
    + ->make_wwn(), ->drop_wwn(). These are created into $TCM_NEW_MOD/$TCM_NEW_MOD_configfs.c
    + *) Generate basic infrastructure for loading/unloading LKMs and TCM/ConfigFS fabric module
    + using a skeleton struct target_core_fabric_ops API template.
    + *) Based on user defined T10 Proto_Ident for the new fabric module being built,
    + the TransportID / Initiator and Target WWPN related handlers for
    + SPC-3 persistent reservation are automatically generated in $TCM_NEW_MOD/$TCM_NEW_MOD_fabric.c
    + using drivers/target/target_core_fabric_lib.c logic.
    + *) NOP API calls for all other Data I/O path and fabric dependent attribute logic
    + in $TCM_NEW_MOD/$TCM_NEW_MOD_fabric.c
    +
    +tcm_mod_builder.py depends upon the mandatory '-p $PROTO_IDENT' and '-m
    +$FABRIC_MOD_name' paramters, and actually running the script looks like:
    +
    +target:/mnt/sdb/lio-core-2.6.git/Documentation/target# python tcm_mod_builder.py -p iSCSI -m tcm_nab5000
    +tcm_dir: /mnt/sdb/lio-core-2.6.git/Documentation/target/../../

    +Set fabric_mod_dir:

    +Using proto_ident: iSCSI
    +Creating fabric_mod_dir:

    +Writing file:

    +Using tcm_mod_scan_fabric_ops:

    +Writing file:

    +Writing file:

    +Writing file:

    +Would you like to add tcm_nab5000to drivers/target/Kbuild..? [yes,no]: yes
    +Would you like to add tcm_nab5000to drivers/target/Kconfig..? [yes,no]: yes
    +
    +At the end of tcm_mod_builder.py. the script will ask to add the following
    +line for to drivers/target/Kbuild:
    +
    + obj-$(CONFIG_TCM_NAB5000) += tcm_nab5000/
    +
    +and the same for drivers/target/Kconfig:
    +
    + source "drivers/target/tcm_nab5000/Kconfig"
    +
    +*) Run 'make menuconfig' and select the new CONFIG_TCM_NAB5000 item:
    +
    + <M> TCM_NAB5000 fabric module
    +
    +*) Build using 'make modules', once completed you will have:
