# ===========================================================================
|
|
#
|
|
# Stage one of module building created the following:
|
|
# a) The individual .o files used for the module
|
|
# b) A <module>.o file which is the .o files above linked together
|
|
# c) A <module>.mod file, listing the name of the preliminary <module>.o file,
|
|
# plus all .o files
|
|
# d) modules.order, which lists all the modules
|
|
|
|
# Stage 2 is handled by this file and does the following
|
|
# 1) Find all modules listed in modules.order
|
|
# 2) modpost is then used to
|
|
# 3) create one <module>.mod.c file pr. module
|
|
# 4) create one Module.symvers file with CRC for all exported symbols
|
|
|
|
# Step 3 is used to place certain information in the module's ELF
|
|
# section, including information such as:
|
|
# Version magic (see include/linux/vermagic.h for full details)
|
|
# - Kernel release
|
|
# - SMP is CONFIG_SMP
|
|
# - PREEMPT is CONFIG_PREEMPT[_RT]
|
|
# - GCC Version
|
|
# Module info
|
|
# - Module version (MODULE_VERSION)
|
|
# - Module alias'es (MODULE_ALIAS)
|
|
# - Module license (MODULE_LICENSE)
|
|
# - See include/linux/module.h for more details
|
|
|
|
# Step 4 is solely used to allow module versioning in external modules,
|
|
# where the CRC of each module is retrieved from the Module.symvers file.
|
|
|
|
# KBUILD_MODPOST_WARN can be set to avoid error out in case of undefined
|
|
# symbols in the final module linking stage
|
|
# KBUILD_MODPOST_NOFINAL can be set to skip the final link of modules.
|
|
# This is solely useful to speed up test compiles
