which serial device to use in that case respectively to not rely on the OFW names of the input/output and stdin/stdout devices. Instead check whether input and output refers to the same device and is of type serial (uart(4) was already doing this) and for the fallback to a serial console in case a keyboard is the selected input device but unplugged do the same for stdin and stdout in case the input device is nonexistent (PS/2 and USB keyboards) or has a 'keyboard' property (RS232 keyboards). Additionally also check whether the OFW did a fallback to a serial console in the same way in case the output device is nonexistent. While at it save on some variables and for sys/boot/sparc64/loader/metadata.c move the code in question to a new function md_bootserial() so it can be kept in sync with uart_cpu_getdev_console() more easily. This fixes selecting a serial console and the appropriate device when using a device path for the 'input-device' and 'output-device' OFW environment variables instead of an alias for the serial device to use or when using a screen alias that additionally denotes a video mode (like e.g. 'screen:r1024x768x60') but no keyboard is plugged in (amongst others). It also makes the code select a serial console in case the OFW did the same due to a misconfiguration like both 'input-device' and 'output-device' set to 'keyboard' or to a nonexisting device (whether the OFW does a fallback to a serial console in case of a misconfiguration or one ends up with just no console at all highly depends on the OBP version however). - Reduce the size of buffers that only ever need to hold the string 'serial' accordingly. Double the size of buffers that may need to hold a device path as e.g. '/pci@8,700000/ebus@5/serial@1,400000:a' exceeds 32 chars. - Remove the package handle of the '/options' node from the argument list of uart_cpu_getdev_dbgport() as it's unused there and future use is also unlikely.

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 ``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.
