ACPI I/O port descriptors use _MIN and _MAX fields to specify the set of allowable base (start) addresses for an I/O port resource along with a _LEN field specifying the length. A fixed resource is supposed to be encoded with _MIN == _MAX, but some buggy firmwares instead set _MAX to the end of the fixed range. Relocating I/O ranges only make sense in _PRS (possible resource settings), not in _CRS (current resource settings), so if an I/O port range with _MAX set set to the end of the range is present in _CRS, treat it as a fixed I/O port resource starting at _MIN.

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. See build(7) and https://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. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
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 kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
