Since we now have knobs to twiddle what used to be set on kernel configurations we can build one base kernel configuration and modify behaviour to mimic such kernel configurations to test them. Provided you build a kernel with: CONFIG_TEST_FIRMWARE=y CONFIG_FW_LOADER=y CONFIG_FW_LOADER_USER_HELPER=y CONFIG_IKCONFIG=y CONFIG_IKCONFIG_PROC=y We should now be able test all possible kernel configurations when FW_LOADER=y. Note that when FW_LOADER=m we just don't provide the built-in functionality of the built-in firmware. If you're on an old kernel and either don't have /proc/config.gz (CONFIG_IKCONFIG_PROC) or haven't enabled CONFIG_FW_LOADER_USER_HELPER we cannot run these dynamic tests, so just run both scripts just as we used to before making blunt assumptions about your setup and requirements exactly as we did before.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
