Introduce kern.opts.mk to hold all the options for kernel module builds. Include this in the right places. Make src.opts.mk optional so that modules can be built outside of the tree in the ports system. PR: 189520

# $FreeBSD$
# Options set in the build system that affect the kernel somehow.
#
# Define MK_* variables (which are either "yes" or "no") for users
# to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the
# make(1) environment.
# These should be tested with `== "no"' or `!= "no"' in makefiles.
# The NO_* variables should only be set by makefiles for variables
# that haven't been converted over.

Remove dependence on source tree options. Move all kernel module options into kern.opts.mk and change all the places where we use src.opts.mk to pull in the options. Conditionally define SYSDIR and use SYSDIR/conf/kern.opts.mk instead of a CURDIR path. Replace all instances of CURDIR/../../etc with STSDIR, but only in the affected files. As a special compatibility hack, include bsd.owm.mk at the top of kern.opts.mk to allow the bare build of sys/modules to work on older systems. If the defaults ever change between 9.x, 10.x and current for these options, however, you'll wind up with the host OS' defaults rather than the -current defaults. This hack will be removed when we no longer need to support this build scenario. Reviewed by: jhb Differential Revision: https://phabric.freebsd.org/D529

# Note: bsd.own.mk must be included before the rest of kern.opts.mk to make
# building on 10.x and earlier work. This should be removed when that's no
# longer supported since it confounds the defaults (since it uses the host's
# notion of defaults rather than what's default in current when building
# within sys/modules).

# Some options are totally broken on some architectures. We disable
# them. If you need to enable them on an experimental basis, you
# must change this code.
Add a note of clarification. MK_* variables only control what modules are built by default. You can still override that with MODULES_EXTRA for experimental features like ZFS and dtrace on some architectures. Also note that kernel config files are not affected by MK_ options listed, though some targets might be.
2015-03-27 17:36:22 +00:00
# Note: These only apply to the list of modules we build by default
# and sometimes what is in the opt_*.h files by default.
# Kernel config files are unaffected, though some targets can be
# affected by KERNEL_SYMBOLS, FORMAT_EXTENSIONS, CTF and SSP.

So, when MAKESYSPATH is defined, trust that it will do the right thing (to catch the JIRA use case). When it isn't defined, assume a standard FreeBSD tree and reach over to grab bsd.mkopt.mk (to fix the /usr/ports use case).

Add support for specifying unsupported / broken options that override any defaults or user specified actions on the command line. This would be useful for specifying features that are always broken or that cannot make sense on a specific architecture, like ACPI on pc98 or EISA on !i386 (!x86 usage of EISA is broken and there's no supported hardware that could have it in any event). Any items in BROKEN_OPTIONS are forced to "no" regardless of other settings. Clients are expected change BROKEN_OPTIONS with +=. It will not be unset, so other parts of the build system can have visibility into the options that are broken on this platform, though this should be very rare.
