their HotRod controller and on SIIG PCI ultra DMA controller. These changes also made lots of the Promise code go away, its all much more generic this way. Get rid of atapi_immed_cmd, instead use the queue to move atapi commands from interrupt context if nessesary, the entire atapi layer has gotten an overhaul. Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet). Use our own malloc names, its a lot easier to track memory usage this way. General cleanup overall.
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 and the contents of /etc. 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 with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/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 LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
