freebsd kernel with SKQ

incomplete in that the PRT routing was not aware of link programming. Fix this by doing all routing through the link devices. The new algorithm for setting up links is: 1. Read _CRS to get current setting. If invalid (not in _PRS), then set to 0. 2. Attempt to call _DIS on the link. If successful, mark the link as not routed. Otherwise, assume it still is. Then when a routing request occurs: 3. Update weights for all IRQs 4. Attempt to route the initial IRQ if valid 5. If that fails, walk through the sorted list, attempting to route IRQs. 6. Configure the trigger/polarity based on _PRS. Other changes: * Add acpi_pci_find_prt() to look up the PRT entry for a given device and acpi_pci_link_route() to select/route the best IRQ for it. * Remove duplicated code in acpi_pcib_route_interrupt() that picked the first IRQ from _PRS. * Remove unneeded arguments from acpi_pcib_resume() and friends. * Ignore _STA on link devices but report if it seems strange. * Add a prt_source handle to the PRT structure since the ACPI struct ACPI_PCI_ROUTING_TABLE uses a fixed-size entry for it. We'll need to dynamically size this object if we want to use it the same way ACPI-CA does. Null-terminate the source.

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.
