INO) for incorrect interrupt map entries on E250 machines. These incorrect entries caused the INO of the on-board HME to be also assigned to the second on-board NS16550 and to the on-board printer port controller. Further down the road caused hme(4) to fail to attach to the on-board HME in FreeBSD 5 and 6 as INTR_FAST and non-INTR_FAST handlers can't share the same IRQ there (it's unknown what whould happen in -CURRENT now that INTR_FAST and non-INTR_FAST handlers can share an IRQ but I'd expect funny problems with uart(4)). - Make sure there are exactly 4 PCI ranges instead of just checking that the bridge has a 'ranges' property in the OFW device tree at all. Besides the fact that currently the 64bit memory range isn't used by this driver it we can't really work with less than 4 ranges and don't have memory for more than 4 bus handles for the ranges in the softc. - Remove sc_range and sc_nrange from softc; for the bridges supported by this driver we no longer need to know the ranges besides the bus handles obtained from them once this driver is attached. That way we also can free the memory allocated for sc_range during attach again. - Remove sc_dvmabase from the softc and pass it to psycho_iommu_init() via an additional argument as we no longer need to know the DVMA base in this driver once the IOMMU is initialized. - Remove sc_dmatag from the softc, there isn't much sense in keeping the nexus dma tag around locally.

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.
