# Due to the extensive use of driver libraries, the SDK usually builds
|
|
# kernel modules from a precompiled object. To avoid various warnings
|
|
# and conflicts, the pre-compiled object must be named differently
|
|
# from the target module, and the object file itself should be
|
|
# appended with "_shipped".
|
|
|
|
# If a module exports any symbols, then the exporting source file must
|
|
# be compiled within the kernel source tree for correct generation of
|
|
# module symbol versions. The symbol source file should be passed to
|
|
# this Makefile via the MODULE_SYM variable.
