# ===========================================================================

|

# 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 in $(MODVERDIR)/, listing the name of the
|
||||
# the preliminary <module>.o file, plus all .o files
|
||||
|
||||
# Stage 2 is handled by this file and does the following
|
||||
# 1) Find all modules from the files listed in $(MODVERDIR)/
|
||||
# 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
|
||||
# 5) compile all <module>.mod.c files
|
||||
# 6) final link of the module to a <module.ko> file
|
||||
|
||||
# Step 3 is used to place certain information in the module's ELF
|
||||
# section, including information such as:
|
||||
# Version magic (see include/vermagic.h for full details)
|
||||
# - Kernel release
|
||||
# - SMP is CONFIG_SMP
|
||||
# - PREEMPT is CONFIG_PREEMPT
|
||||
# - 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.symers file.
|
||||
|
||||
# KBUILD_MODPOST_WARN can be set to avoid error out in case of undefined
