# Kbuild - the "makefile" used to build the dfrgx software.
|
|
#
|
|
# Invocations
|
|
# 1. usual: as a part of a full kernel build if CONFIG_GFX_RGX_DEVFREQ is
|
|
# defined as "y" or "m". This file ("Kbuild") is selected by the kernel
|
|
# build system because "Kbuild" has priority over "Makefile".
|
|
#
|
|
# In which case, either:
|
|
# -- (CONFIG_GFX_RGX_DEVFREQ=y) the dfrgx software is built-in to the kernel.
|
|
# or
|
|
# -- (CONFIG_GFX_RGX_DEVFREQ=m) the dfrgx software is built as a module into
|
|
# dfrgx.ko . HOWEVER, some portions of dfrgx (e.g., hooks into the
|
|
# graphics device driver) are still built into the kernel.
|
|
#
|
|
# 2. Alternate invocation: The module may be built separately from the rest of
|
|
# the kernel (typically to reduce debug cycle time during development):
|
|
# File "Makefile" in this directory is invoked from the command line,
|
|
# defines DF_RGX_EXT_MOD_BUILD as "y", and then causes Kbuild to be invoked.
|
|
# The kernel against which the module will be loaded should have been created
|
|
# in the usual way with CONFIG_GFX_RGX_DEVFREQ=m.
|
|
# Requires one of the following have been done:
|
|
# -- "make modules_prepare" (ok, but does not set up Module.symvers)
|
|
# -- "make" or "make bzImage" -- regular kernel build to establish build
|
|
# environment.
|
|
|
|
# To add verbosity during build:
|
|
# make KBUILD_VERBOSE=1
