| # 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 |
