freebsd kernel with SKQ
d3109d3971
the kernel itself: If building for the same architecture as the build host,
the kernel build assumes that the host toolchain is capable of building the
kernel. If it's not, "make kernel-toolchain" will bootstrap a new set of
tools that will work.
With this change the same assumptions are made for building kernel tools,
and the existing host toolchain is used to do the build (notably, the build
doesn't link the tools with the legacy libraries, which may not even exist).
If ever for some reason the host toolchain isn't capable of building the
kernel tools, then doing a "make kernel-toolchain" will bootstrap newer
tools to get the job done.
So when built as part of buildworld or kernel-toolchain, the kernel tools
are built using the XMAKE (via BMAKE) commands and environment. When built
as part of building just the kernel on a same-target host, the tools are
built using the new KTMAKE commands and environment. What doesn't jump
out at you in the diffs is that the difference between BMAKE and KTMAKE
is that BMAKE contains this magic line which changes how the build is done
because it changes what files get included for .include <bsd.prog.mk> and
other standard includes:
MAKEFLAGS="-m ${.CURDIR}/tools/build/mk ${.MAKEFLAGS}"
and KTMAKE doesn't, and contains this instead:
TOOLS_PREFIX=${WORLDTMP}
Hopefully this brings the "how to build aicasm with the right toolchain"
saga to a conclusion that works in all usage scenarios that have
historically been supported.

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
