- trying for a fit for a PnP configuration from a device - soaking up resources from a configuration that were not allocated by the driver do not attempt to activate them. Only a device driver that is aware of the nature of the resource and its suitability can be certain that activating a resource, particularly a memory resource, is a safe thing to do. This was prompted by the discovery that many systems report all physical memory through a PNP0c02 device; activating this resource maps all physical memory into the kernel's virtual space, either blowing out the kernel pagetable or in the worst case causing a panic in pmap_mapdev() if the system has too much physical memory.

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).
